  • Offer Profile

  • When it comes to surface finishing, Rösler is naturally the number one choice for many companies across the globe.

    For over 80 years, the name Rösler has stood for the highest quality in the production of machines and integrated systems for mass finishing and shot blasting as well as the development and production of dedicated consumables. To put it simply – surface finishing is in our DNA!

    Due to additive manufacturing becoming an increasingly popular production technology, in 2018 we combined all the activities of the Rösler Group relating to 3D printing under the brand AM Solutions. This includes the division for automated post-processing solutions (3D post-processing technology) and a comprehensive service division (Manufacturing service partner).

     

Product Portfolio

  • World-class mass finishing solutions for your perfect surface

  • Unlimited applications – no matter what your requirements

    Rösler mass finishing offers more than 1,000 surface finishing options.Metal, plastic, ceramic or wood, deburring, descaling, rust removal or polishing – the uses for mass finishing machines are almost limitless and they have been used successfully day in and day out for decades in many industries such as aerospace, medical technology, the automotive sector and the coin and jewelry industries. Nowadays, almost every workpiece requires functional or aesthetic surface finishing.
    Mass finishing, also referred to as tumbling or vibratory finishing, is a technique derived from nature – surfaces are polished using grinding media and compounds in the same way that sand and water smooth pebbles in the riverbed.

    Mass finishing offers a big advantage over other competing methods. By combining processes, several production steps can often be carried out simultaneously. As a result, processing time is reduced, fewer resources are used and it is more cost-effective.

      • CONTINUOUS FLOW INSTALLATIONS

      • If mass finishing needs to integrated into a continuous process, through-feed systems are a logival choice.

        Through-feed systems are ideally suited for the fully automatic vibratory finishing of stampings, castings, forgings, or machined work pieces. Deburring, grinding, rounding, and ball burnishing are the most common processing methods for through-feed systems.

        There is a choice of through-feed systems in linear form and in the Rotomatic variant, a special development of Rösler. The numerous special features of our Rösler through-feed systems are continually opening up new fields of application. The sophisticated machine design, conceived for continuous industrial operation under demanding conditions, various work bowl sizes, the robust drive technology, a large-area separating station, and the modern control technology ensure maximum reliability – even under the harshest of operating conditions. No other supplier can offer a more diverse and wider range of through-feed systems.

         

      • HIGH ENERGY DISC SYSTEMS

      • Our high energy disc systems make mass finishing more efficient than ever before. Compared with conventional vibratory finishing, a 10- to 15-fold increase in performance can be achieved with the help of centrifugal force. High energy disc systems are inspiring not only because of their speed but also because of their processing spectrum. Among other things, they are used for deburring, grinding, rounding, or polishing stampings, castings, forgings, and machined work pieces – from thin-walled to solid. High energy disc systems are used in medical technology, jewelry and eyewear manufacturing, as well as in the automotive sector as well as in many other special applications.

      • DRYERS

      • Almost all processing methods in vibratory grinding are wet processes. In order to be fed into the next production process, work pieces usually must be dried after mass finishing. We offer our customers sophisticated solutions that allow the drying process to follow the vibratory grinding process smoothly and automatically. Among the requirements placed on the systems are that they can be directly connected to the mass finishing system in terms of control technology and that they can be operated in an energy-efficient manner while maintaining high drying performance.

      • Centrifuge technology

      • Today, almost any mass finishing process can be linked to a Rösler process-water cleaning system. The process water is cleaned of the solids generated during mass finishing and can then be re-used in the finishing process. This makes the process much more sustainable and cost-effective.

        The basis of modern process-water cleaning technology relies on the principle of two-phase solid-liquid separation using centrifugal force. Depending on cleanliness requirements, particle sizes and materials, the systems can achieve throughput rates of up to 6,000 liters per hour. Thanks to the high acceleration of up to 2,000 g, particles larger than 2.0 µm are separated from the liquid and collected by the centrifuge rotor as a filter cake. By using our process-water cleaners, which have been specially developed for process water recycling, the physical separation performance of the centrifuge can be optimized. This ensures that the quality of the process fluid is maintained for the entire service life. We offer an extensive range of highly effective process-water cleaners and chemical additives from our own development and production.

         

      • ROTARY VIBRATORS

      • Rotary vibrators are flexible all-rounders. They have been used for deburring, grinding, cleaning, polishing, and descaling as well as many other surface processing methods. The range of materials that can be processed in rotary vibes is virtually unlimited. Metal, plastic, ceramics, rubber, wood, and even glass can be processed effortlessly in a rotary vibrator. A wide and unique range of different sizes and work bowl designs in the standard range results in the right solution for every application. Our engineers are happy to take on the challenge of even unusual processing requirements – including the necessary automation.

        At Rösler, we focus on ensuring that our machines have the longest possible service life. That’s why we place particular importance on functional design, high-quality materials, and the highest quality of workmanship. Our engineers are continually developing the particularly powerful and adaptable circular vibrator technology, thereby expanding the possible range of applications.

      • SURF-FINISHER

      • With our innovative special systems for single-part processing, we enable the targeted processing of high-quality, demanding work pieces by avoiding contact between the work pieces. Drag finishers, surf finishers, multi-surf finishers, and plunge grinders take mass finishing to a whole new level. These types of systems are used in various configurations in the aerospace, automotive, and medical technology industries as well as in the tooling industry.

        The basic principle of these types of systems is the same: the work piece or work pieces are attached to a clamping device – either to processing spindles or to a robot – and immersed in the container filled with finishing media. Rotating either the work bowl or the parts on the fixture creates the relative movement between the part and the finishing media. This way, grinding, deburring, polishing, or edge rounding is performed on the part based on the type of finishing media used. Finsihing media especially developed for this intensive processing ensure high-quality and economical processing of the work pieces.

         

      • Industrial cleaning systems

      • Industrial cleaning systems are used in countless industries – because wherever production takes place, work pieces have to be cleaned of release agents, oils, chips, or abrasion and much more. We offer our customers industrial cleaning equipment for spray cleaning with aqueous solutions. We focus on the two main types of equipment for interlinking with blast or mass finishing applications: continuous cleaning systems and drum cleaning systems.

        A functional aqueous cleaning system must meet standardized cleanliness specifications. We therefore coordinate all systems and processes in the best possible way. That’s why we use classic continuous cleaning systems for automatic production systems. Or multi-functional, specially designed mass finishing systems that combine processes: cleaning, pickling, neutralizing, smoothing, polishing, and drying in an automated program sequence.

      • Tub Vibrators

      • For the processing of particularly large-volume and/or heavy work pieces in the mass finishing process, Rösler trough vibrators have proven themselves time and again. These systems can be used for all common mass finishing processes – whether deburring, edge rounding, grinding, polishing, or ball burnishing. Tub vibrators are suitable for single part processing as well as for processing several components simultaneously. In the second case, the parts are either separated by dividers or, in the case of sensitive components,mounted on special fixtures.

      • WASHING AND DRYING SYSTEMS

      • Minimal parts handling, maximum surface result: Washing and drying systems combine the finishing of small or mass-produced parts with subsequent cleaning and drying in a single, compact system. This makes the mass finishing process not only unsurpassed in its effectiveness, but also extremely cost-effective: part-on-part finishing in these systems does not require media for these special process. T the process becomes less expensive and the workpiece price can be significantly reduced.

        Both circular vibrators and centrifugal systems are available in the WTA series. Both systems allow complete workpiece discharge - either by tilting the entire work bowl or by bottom discharge of the workpieces.

         

    • SHOT BLASTING TECHNOLOGY: A TECHNOLOGICAL LEADER IN MECHANICAL SURFACE FINISHING

    • Unlimited applications – no matter what your requirements

      Our shot blasting machines offer you almost unlimited options for surface finishing: from deburring, descaling, de-sanding and rust removal to roughening, cosmetic blasting, smoothing and edge rounding all the way to shot peening. After all, the functionality and aesthetics of surfaces are not only an important sign of quality for technical products, they also contribute significantly to their success on the market. Surface finishing is therefore nearly always essential and has to be integrated into existing production processes as an additional, value-added step.

      Not many technical procedures have such a variety of uses as shot blasting, especially when it comes to metal surfaces. However, other materials, such as concrete, sandstone, glass, textiles, wood and plastics, can also be processed with machines from Rösler.

        • Tumble belt blast machines

        • Tumble belt blast machine are suitable for the derusting, deburring, roughening, or cleaning of robust work pieces of any size that are suitable for tumbling. Depending on the type of system, the work pieces are processed in either batches or in continuous operation. The use of a tumble belt blast machine is also ideal for shot peening, matting, or general surface finishing. When it comes to the material of the work pieces, the spectrum ranges from small plastic parts to massive, sand castings depending on the system design, Depending on the system type, the machines are used for blasting transmission parts, forged parts, and light metal components.

           

        • WIRE MESH BELT BLAST MACHINES

        • RDGE wire mesh belt blast machines

          The RDGE wire mesh belt blast machine is a true multi-talent in homogenizing surfaces, and can be used for de-sanding, deburring, roughening, cleaning, and descaling, among other things.

          Thanks to its specific design, this wheel blasting machine is particularly suitable for processing long, flat, or voluminous parts. However, even small work pieces that are not suitable for roller tables (e.g., castings, flame-cut parts, or car body parts) can be blasted economically and reliably using a wire mesh belt blast machine.

           

        • ROTARY TABLE BLAST MACHINES

        • Rotary table blast machines, satellite table blast machines, and swing chamber blast machines are suitable for processing larger work pieces with often more complex structures. They all enable particularly targeted and reliable blasting of single components in one-piece flows in chambers, in specially separated segments, or on satellites.

          In order to avoid idle time as a result of individual part processing, in some of the systems, it is possible to process work pieces in the blast chamber and simultaneously load and unload other work pieces in a separate area. The RST satellite table blast machine and the RWK swing chamber blast machine offer this process advantage. The systems are suitable for stand-alone operation or, depending on the system type, can be integrated into production lines (RWK/RST).

           

        • Roller conveyor blast machines

        • Roller conveyor blast machines are suitable for the descaling, paint stripping, rust removal, roughening, and cleaning of work pieces such as sheet metal plates, profiles, beams, and pipes. Depending on the type of system, thin sheet metal plates up to massive steel profiles weighing several tons can be processed. The largest systems allow optimal processing of work pieces up to 6,000 mm in height and up to 5,000 mm in width.

          During processing, the work pieces pass through the pre-chamber, blast cabin, and post-chamber of the system – either one after the other or in batches on a roller conveyor. Depending on the type of system, shot blasting is carried out with precisely positioned blast turbines equipped with energy-saving motors. The blasting result is all-round, comprehensive, and always reproducible. Roller conveyor blast machines can be easily integrated into existing production lines. Despite their sometimes considerable size, the systems are easy to maintain because the components can be conveniently reached through large access openings and inspection platforms.

        • PRESERVATION LINES

        • A preservation line is a highly complex, individually configured surface treatment system that fully automatically pre-heats, derusts, and descales and then applies a temporary corrosion protection – the welding primer – to steel. Preservation lines can take on enormous dimensions. They are used where large quantities of steel sheets or profiles have to be processed (e.g. in shipyards, steel trades, or rolling mills).

          The main component of the preservation line is a roller conveyor blast machine. Various components are then installed upstream and downstream.

           

        • Turning chamber blast machines

        • Rotary table blast machines, satellite table blast machines, and swing chamber blast machines are suitable for processing larger work pieces with often more complex structures. They all enable particularly targeted and reliable blasting of single components in one-piece flows in chambers, in specially separated segments, or on satellites.

          In order to avoid idle time as a result of individual part processing, in some of the systems, it is possible to process work pieces in the blast chamber and simultaneously load and unload other work pieces in a separate area. The RST satellite table blast machine and the RWK swing chamber blast machine offer this process advantage. The systems are suitable for stand-alone operation or, depending on the system type, can be integrated into production lines (RWK/RST).

          These systems are used for shot peening, deburring, cleaning, roughening, and homogenizing surfaces.

           

        • MULTI-TUMBLER

        • Thanks to the gap-free design of its work piece drum, the “RMT” multi-tumbler is particularly well suited for small parts processing. With this system, work pieces can be thoroughly cleaned from scale, sand, or rust in short cycle times.

          At the same time, the RMT is a shot blast machine with special inner values. The inner wall of the multi-tumbler barrel has specially shaped ribs, and the bottom has been designed as a three-sided pyramid. This unique combination provides the innovative “multi-tumble” effect of the various work pieces. When the drum rotates, the internal ribs ensure complete mixing of the work pieces. The pyramid also causes an exchange between upper and lower layers. This multiple rotation ensures that all surface areas are evenly and reliably exposed to the blast media during the process.

        • Tumble belt blast machines

        • Tumble belt blast machine are suitable for the derusting, deburring, roughening, or cleaning of robust work pieces of any size that are suitable for tumbling. Depending on the type of system, the work pieces are processed in either batches or in continuous operation. The use of a tumble belt blast machine is also ideal for shot peening, matting, or general surface finishing. When it comes to the material of the work pieces, the spectrum ranges from small plastic parts to massive, sand castings depending on the system design, Depending on the system type, the machines are used for blasting transmission parts, forged parts, and light metal components.

          In the blasting area, the work pieces are constantly in motion. Through the perforated tumble belt, which is made of rubber as standard (but optionally also of steel), the parts are circulated and simultaneously blasted with the aid of up to three high-performance turbines or with compressed air. Typically, up to four turbines are installed in continuous feed tumble belt blast machine. For everyday foundry use, the systems can also be lined with manganese steel plates. This ensures both a longer service life and lower maintenance requirements.

        • Roller conveyor blast machines

        • Roller conveyor blast machines are suitable for the descaling, paint stripping, rust removal, roughening, and cleaning of work pieces such as sheet metal plates, profiles, beams, and pipes. Depending on the type of system, thin sheet metal plates up to massive steel profiles weighing several tons can be processed. The largest systems allow optimal processing of work pieces up to 6,000 mm in height and up to 5,000 mm in width.

          During processing, the work pieces pass through the pre-chamber, blast cabin, and post-chamber of the system – either one after the other or in batches on a roller conveyor.

          • Plastic Media

          • Plastic grinding media are used for the gentle deburring, edge rounding or grinding of brass, aluminum or copper. They are only approximately half the weight of ceramic media.

          • Compounds

          • Compounds are the magic potion of mass finishing – their composition determines the reliability of the vibratory finishing process and the additional effects achieved in addition to the removal of material. They are available as liquids, powders and pastes.

          • Polishing and Drying Media

So, take a look through our options – then challenge us. We look forward to learning about your products.

            • ROUGHENING

            • Many industrially manufactured workpieces need to be roughened during the production process. This is generally done using shot blasting.

              Roughening is usually either wanted for aesthetic reasons or needed in order to prepare the workpiece for further processing. For example, many surfaces need to be roughened before coating or bonding. This increases the surface area, which improves adhesion.

            • DEBURRING

            • Protrusions of material, such as sharp edges, fraying and splinters, are classified as burrs. They have to be removed, i.e. deburred, during the production process.

              Deburring is an important part of many process chains because burrs occur during nearly all manufacturing processes. They are not only a safety hazard, they also affect further processing and can significantly impact the functionality of a workpiece. Deburring is especially important in the metal industry because casting, sawing, drilling and milling always create unwanted protrusions in different places.

            • STRIPPING

            • The stripping and repainting of workpieces is usually carried out to prevent corrosion and to improve appearance. Surfaces can be completely or selectively stripped.

              Paint stripping is regularly required in the aerospace industry. In this sector, the limits of technical feasibility are constantly being redefined and minimum production tolerances must be met.

            • RUST REMOVAL

            • Removing rust from metal components made of iron or steel is one of the classic applications of mass finishing and shot blasting technology.

              Metal parts often need to have rust removed before further processing. The blasting process used is known as blast cleaning. This effectively and completely removes the unwanted layer of corrosion without altering the surface of the base metal.

            • DE-SANDING

            • De-sanding workpieces made in a foundry places very high demands on the equipment, the wear resistance of the turbines and the performance of the cleaning system for the blast media.

              How can a workpiece be quickly and cost-effectively de-sanded following the casting process and therefore best prepared for the next step in the production process? This question is key to everyday foundry operations. The number of parts that need to be processed as well as the size and complexity of the parts determine the type of machine technology required.

            • DECOATING

            • Stripping is a cleaning process and is one of the most frequent types of surface finishing. Dirt or unwanted materials are removed during this process.

              Decoating processes can be semi-automatic or fully-automatic. The decisive question when searching for the right machine and suitable consumables is always: How much material removal gives you the desired result?

              With the right machine, surface layers from materials such as concrete, sandstone, glass, wood or textiles as well as plastics and metals can be removed. The surface of the workpiece should not be damaged during the process.

            • DISCALING

            • Cast, forged parts need a clean surface so that further processing can be carried out successfully. Often, a brighter surface is also desired.

              The complete descaling of surface oxidation, scale and hard residues is a prerequisite for numerous subsequent processing stages.

            • HIGH PRESSURE WATER JET BLASTIING

            • High-quality workpieces need a particularly gentle finishing process. High-pressure water jet blasting is gentle on materials, environmentally friendly and blasts waters at up to 5000 bar.

              Very hard coatings can be removed in a particularly gentle way using high-pressure water jet blasting.

              Blasting with water through a rotating multi-nozzle also has many more benefits. For example, no blast media is used which minimizes the abrasion to the base material. Subsequent cleaning of the workpieces due to dust or blast media is eliminated. Temporary corrosion protection is also possible by adding compounds to the process water. The option to continually re-use the process water in a closed-loop system also makes high-pressure water jet blasting very environmentally friendly.

            • ISF®-PROCESS

            • Isotropic Superfinishing, ISF® for short, is also known as the “REM process” and stands for chemically accelerated surface finishing.

              The patented ISF® process is the ideal combination of chemical and mechanical surface finishing. It is used when high-quality parts need to be finished as gently as possible. By using compounds, usually in the acidic pH range, a thin conversion layer forms on the parts being processed. This is then removed by the special grinding media used in the process. This ensures the permanent removal of the material. The subsequent neutralization phase produces super-smooth, shiny and decorative surfaces. Another benefit of this surface finishing technique is that the achieved surface profile reduces the rolling and running noises of components, while also increasing their service life.

            • EDGE ROUNDING

            • Workpieces made from a wide range of materials can have sharp edges, depending on the manufacturing process. These usually need to be rounded before further processing for technical or haptic reasons.

              Vibratory finishing is the most cost-effective solution for edge rounding mass-produced parts. Even very sensitive workpieces with high quality requirements can be rounded in an economical, precise and repeatable way using this process.

            • WET BLASTING

            • Cleaning, stripping, cosmetic finishing, deburring and lots more can be carried out very gently using a combination of blast media and water.

              Wet blasting is particularly suitable for delicate, precision-machined workpieces. This method is not just gentle, it is also efficient because less blast media is required due to the protective layer of water. There is also no dust and very fine blast media can be used. Wet blasting also enables the blasting of materials which create hazardous conditions.

            • POLISHING / SMOOTING

            • Very smooth and high-luster surfaces are a sign of proven quality and aesthetics. A perfectly polished surface can also be necessary for a product to achieve its optimal function and life span.

              Polished and smooth surfaces catch the eye and feel good. Fine jewelry and cutlery are given this “finishing touch”.

            • CLEANING, DE-OILING OR DEGREASING

            • Oil, grease or lubricants are used in many manufacturing processes, and even when used for modern minimum lubrication, a small amount remains on the workpiece. This residue needs to be removed before further processing or surface finishing.

              Industrial cleaning, i.e. the cleaning, de-oiling and degreasing of workpieces, during the production process can account for up to 20 percent of manufacturing costs due to rising quality requirements as a result of the high quality and functional expectations for components. Cleanliness requirements for components are set out with increasingly narrow limits and must be reliably met.

            • GRINDING

            • Surface defects, mold seams or roughness on workpieces made using traditional manufacturing processes or additive manufacturing methods (3D printing) must be removed before further processing.

              Grinding surfaces is an ancient technique that people have taken from nature and perfected over centuries. In nature, pebbles are rounded in the riverbed by sand and water, while in industrial vibratory grinding, the workpieces are processed using grinding media, water and compounds.

            • SHOT PEENING

            • Shot peeing uses special media and a very targeted blasting process to improve wear and fatigue life of components.

              In the shot peening process, a specially chosen blast medium is selected and repeatedly propelled at high speed onto the usually metal surface. By generating a residual compressive stress up to a maximum penetration depth in the surface of a component, the wear resistance and fatigue life of highly loaded components (gears, turbine blades, etc.) is significantly improved. For safety reasons, shot peening is therefore now absolutely necessary in the aerospace industry.

            • DRY ELECTROPOLISHING (DRYLYTE)

            • The DryLyte process is a completely new method of surface finishing. No liquid is used as electrolyte, instead it uses an electrolyte-containing, solid polishing medium.

              The patented DryLyte Technology from our partner GPAInnova is a new post-processing method for cast, sintered and milled metal parts of any kind. It is used in sectors with the most demanding requirements, such as the aerospace industry and the production of luxury goods. It can be used in combination with the well-known mass finishing process or by itself, provided that the initial surface already has a minimum roughness. The process works by combining the electrical flow generated by the high precision rectifier with the movement of the pieces in the electropolishing media. This results in an ion exchange, which removes material only from the peaks of the roughness. It does not round edges and can access geometries that are difficult to reach mechanically.

            • SPECIAL APPLICATIONS
