              Range of application
              The Nearly every automobile manufacturer is in the processof downsizing its passenger cars’ engines. Small displacement engines are lighter and have reduced friction loss, thus making them more fuel efficient and able to meet more stringent emission limits.

              To achieve this technically, tomorrow’s crankshaft bearings will need to have smaller diameters and lengths, and will often need to be harder — resulting in higher stresses and strains due to increased pressures. Thus, the surfaces of the main and pin bearings will require more precise microgeometry.

              Rising to this manufacturing challenge, Supfina has created a new machine line: the Supfina CenPro S. It combines high workpiece quality with short cycle times, not to mention a smaller footprint and lower operating costs.

              That’s because the LCM Crank can be conveniently equipped with the right finishing modules for each machining task.

              Up to six Supfina attachments (either permanently mounted, manually adjustable, or numerically controlled) can be used simultaneously, including stone- and tape-finishing units as well as deburring and polishing devices.

              Equipped with the latest machine technology, the LCM Crank’s modular system meets the quality and process reliability needs demanded by the automotive industry and its suppliers.

              In addition to “simple” shaft geometries such as transmission, balancer, cam, and eccentric shafts, a crankshaft’s main and connecting rod bearings can also be easily machined. Just about any material — from soft iron to hardened steel — can be finished.

              LCM Crank series machines can be loaded and unloaded manually, by gantry loader, or by robot — thus guaranteeing cost-effective part handling for single-unit or small-run production.

              • Fittings technology

                Dams, refineries, pipelines, and chemical plants: All of these environments must control fluids and gases. Thus, they require reliable fittings, of which the ball valve is at the heart. That’s because ball-shaped surfaces are the ideal shape for accurately controlling technical processes of this kind.

                They must be leak-proof, withstand tremendous loads, and have the ¬longest possible service life. These requirements can be met only if the surface is perfect — and Supfina’s technology makes that perfection possible.

                Medical technology

                Replacing a hip joint is not as easy as changing a washer in a leaky tap.

                From the outset, everything must fit perfectly. Of course, the surgeon’s skill is integral to ensuring that, following the operation, the patient moves freely and without pain. But also crucial is the quality of the artificial femur head and ace¬tabulum, both of which must be finished to an extremely high standard of accuracy.

                In many cases today, the preferred material for hip replacement parts is ceramic, which requires very specialized processes and is more difficult to finish than steel. But by using Supfina’s superfinishing technology, we can achieve the high quality that is necessary for these ceramic parts.

                  Perfection is achieved when the final finishing touches have been applied. In the automotive industry, components must meet the most exacting standards so that, in tough day-to-day running, parts can last for the maximum time.

                  Whether the part’s surface is flat or curved, our machines achieve the best possible finish. This result is crucial for load-bearing sealing surfaces, because perfect finishes make parts virtually wear-free and tough enough to last.

                  While our flat finishing machines can give a component the surface perfection it needs, that’s still not enough for us. With each improvement it becomes more difficult to make our machines even better — but this ongoing pursuit of excellence is a challenge that we’re happy to embrace.

                    • Flat components

                      Accurate flat surfaces are often required even if the workpieces they belong to are not visible. In household appliances, in entertainment technology, in the manufacture of clocks and watches, in the automotive field – nearly every product today contains small, flat parts.

                      Due to the high demands made on tolerances, evenness and parallelism, the workpieces have to be ground to a very precise degree to enable them to perform as intended. They are often components that the user never sees but which are essential so that the clock, watch, pump, gearbox and car function properly. The manufacturing process requires both quality and economical processes to be in the foreground.

                      Economy

                      This is where Supfina is setting new standards. Our double-disk grinding technology enables high product quantities to be machined to consistently high standards in the shortest possible times. The result is workpieces with high surface quality, evenness and parallelism while ad­hering to the tightest of tolerances and keeping costs per part to a minimum.

                            • Superfinish

                            • What is superfinishing? The perfect finish.

                              Tape and stone superfinishing
                              Superfinishing is a chip removing machining process. But not one that is comparable to any other. In contrast to the classic lathe turning and grinding methods, there is full surface contact between the tool and the workpiece.

                              This is precisely the feature that produces the unique characteristics of a perfectly machined surface. This is superfinishing!

                              By overlaying workpiece rotation and tool oscillation, each individual grain travels along a sinusoidal line – a feature typical for this process.

                              All the grinding grains in contact with the workpiece create a machining pattern by means of overlaying individual sinusoidal lines that cross each other at a particular angle. This generates a specific, defined pattern of grooves and plateaux, which, in turn, results in the particular advantages of the superfinishing process. The grooves act as channels to aid uniform distribution of the lubricant, while the plateaux guarantee a high percentage contact area.

                              The tools in use here are either bonded grinding compound on a solid substrate, such as ceramic, or on a flexible backing such as a textile tape.

                              Uniform lubricant distribution, higher bearing ratio, improved microgeometry, optimized peak heights – this is workpiece quality made by superfinishing.

                              Machinable materials
                              The materials used today are many and varied. It is not only steel in all its many alloys and qualities that can be machined using Supfina machines. The superfinishing process is suitable for all those materials that can be machined with geometrically undefined cutting edges.

                              These materials include ceramic, plastic, monocrystalline silicon, cast iron and non-ferrous metals.

                              But such coatings as tungsten carbide, chromium and copper are also processed in Supfina machines to provide them with the perfect surface finish.
                              • Machining of various materials using superfinishing technology
                              • The right machining process for each specific workpiece
                              • The right superfinishing system for the current requirement
                            • Precision Abrasive Finishing

                            • What is the best process for producing flat surfaces with the highest precision? Given the wide range of applications for an enormous variety of workpieces, this question poses great challenges for manufacturers.
                              Supfina has the answer — and three superior methods for getting the job done: double-disk grinding, flat finishing, and fine grinding.

                              Double-disk grinding
                              Considered one of the “classic” grinding processes, double-disk grinding is performed when both sides of a workpiece must be ground so that both surfaces are exactly plane and parallel. The workpiece is not fixed for this process. Instead, it is loosely placed in the “nest” of the workpiece carrier. Then both sides of the workpiece are simultaneously machined between two grinding wheels. The upper grinding wheel is adjusted with the “tilt” navigation setting, which allows the upper wheel to maintain the desired angle with the lower wheel. Thus, the gap between the grinding wheels is greater on the infeed side than on the outfeed, resulting in the required amount of stock removal.
                              Through regular dressing, the grinding wheels maintain their form and sharpness.

                              Flat finishing
                              Flat finishing is primarily the process of using a cup wheel to machine a workpiece’s face. The workpiece is clamped in a chuck and rotated. The rotating cup wheel is then precisely advanced to the workpiece’s surface.
                              Precision slides allow the finishing unit to be adjusted in multiple directions — thus giving the workpiece a characteristic “cross-hatch” pattern, in addition to concave or convex adjustments. With these capabilities a flat, concave, convex, or spherical surface can be produced. One key difference between double-disk grinding and flat finishing is that, for the latter process, the tool is self-dressed during the machining of components and regular wheel dressing is not necessary.

                              Fine grinding
                              Fine grinding is also used when workpieces require both surfaces to have plane parallelism, but with more precision than can be achieved with double-disk grinding. Workpieces are placed in carriers that have teeth on the outside diameter. An inner pin ring rotates the carriers as they shift on a stationary outer pin ring in an orbiting manner. Machining takes place between two rotating grinding wheels. The optimal machining force is applied by the upper wheel, which is mounted on an oscillating pendulum. Fine grinding’s central feature is that a fixed number of parts can be processed simultaneously, or in batches.
                              Each of these machining technologies has its particular strengths. For maximum stock removal as well as output of finished workpieces, double-disk grinding is preferred. For example, within large-scale production, single cams can be ground with a cycle time of fewer than 0.5 seconds with a continuous-feed loading system.
                              However, for maximum precision and size accuracy, fine grinding is preferred. Hydraulic components, for example, can be finished with an accuracy of ± 0.001 mm.
                              Flat finishing distinguishes itself in that workpieces are clamped, therefore making the clamped surface a geometric reference point for perpendicularity and flatness. Thus, in the case of transmission components, the perpendicularity of flat surfaces and bores can be ensured.
                            • SpeedFinish®

                            • Supfina’s SpeedFinish® technology was developed to combine the advantages of grinding with those of superfinishing, i.e. to achieve high ­removal volumes in the shortest possible finishing times while achieving homogenous surface roughness free of half-moon markings.

                              The name says it all: it is not only called SpeedFinish®, this system is faster than comparable processes. Workpieces are machined at high speed, which reduces the machining process by as much as 75 percent.

                              This improves efficiency while, at the same time, improving competitive advantage thanks to reduced costs.
