Product Portfolio
  • Centrifugal Disc Finishing Machines

  • In these machines, the workpieces and the grinding material are added loosely into a container which is open at the top and has a plate-shaped base which causes a torus-style tumbling effect. The centrifugal force flings the workpieces and the grinding elements against the stationary aerodynamic inner wall of the plate-based working bowl. In doing so, the workpieces and grinding elements perform a relative movement as a result of their different density. This dynamic flow enables high, targeted material erosion in very short processing times compared to vibrators or drums.

    • Trough Vibrators

    • During this process, the workpieces and the grinding material are added loosely into a container which is open at the top (trough). The items are then oscillated through an imbalance in weight, which forces them into a screwing or annular torus-like movement (long trough or round trough). Due to their different density, the workpieces and grinding media perform a relative movement, particularly during the negative amplitudes which enables material erosion. Vibrators are universal mass finishing machines, which can be used for a variety of workpieces and processing objectives unlike drum and centrifugal grinding which may cause some problems during the process. They are particularly suitable for the economically priced high polish finishing of extremely sensitive workpieces which reach from rough pre-grindings up to the preparation of surfaces ready for electroplating.

      • Separation

      • During the massfinishing process, the separation of workpieces and media is an essential element and it is important to integrate into the whole process. We offer a variety of manual and automated separation systemsand gladly help you to decide for the optimal solution for your process.
          • Manual separation

            • Separation of workpieces by manual screen box
            • By manual oscillation of the screen box, the abrasive falls into the collection container.
            • The work pieces remain in the screen and can now be removed.
            • Screens are easy and quick to change.

          • Process Media - Consumables

          • Making the right choice of process media in terms of quality and shape is the key for an optimal finish in the interplay between workpiece and machine. For this purpose there is a wide variety of grinding and polishing elements available as well as granulate, compounds and additives for your process design. We are happy to advise you!
              • Ceramic Media

              • Ceramic grinding and polishing media are distinguished by hardness ratings of 7.3 - 8.5 Mohs and density ratings of 2.37 - 3.51 g/cm³. This results in high grinding performance with high grinding pressure. Light and shiny surface finishes are typical. 
                Ceramic grinding and polishing media have a long service life and can maintain their original shape during operation.
              • Plastic Media

              • Synthetically bound grinding and polishing media have a lower density rating of 1.61 - 1.89 g/cm³ and, thanks to the selection of different grinding effects, they are the best choice for gentle and splinter-free processing by high demands on the surface quality of non-ferrous metals or soft surfaces.
              • Stainless Steel Media

              • For ball burnishing and pressure deburring, smoothing and compacting the surface of non-ferrous metals and light alloys.
              • Compound

              • During the grinding process with water, compounds absorb the by-product of the grinding elements and the workpieces while helping to transport these away. Thanks to additives in the compound, this process is accompanied by cleaning, brightening and passivation of the workpiece.
              • Polishing- and Drying Media

              • Nut shell granulate is used as a carrier medium for polishing and grinding pastes in dry polishing and grinding. A distinction is made between unimpregnated qualities and impregnated qualities appropriate to their utilization which have to be resharpened at regular intervals.

                For the right polishing and grinding pressure, there is a whole range of grain sizes that can be used for your application.

                There are also corn grits in different versions available

              • Additives

              • With additives such as pastes and adhesive oils the proportion of polishing and grinding particles in dry polishing and grinding processes are metered ("resharpening") and binds grinding, dust and dirt particles ("regreasing").
