Superfinishing machines SPH, SPHK and SPV

Superfinishing machines with rotating tools are used for the machining of spherical surfaces and flat surfaces with self-sharpening superfinishing cup wheels or superfinishing sleeves.

Typical for flat surface machining is the parallel displacement of tool and workpiece axis and a low speed. In contrast to grinding and fine turning there are no changes to the microstructure in the edge zone through thermal changes to the surface. As high level of overlapping results in a very good correction of the flatness. At the same time the plane parallelism and wobble can be improved. The workpiece and cup wheel counter rotate.

With the machining of spherical surfaces the axes of symmetry and rotation of the tool and workpiece intersect. The very high form correction is achieved by a high level of overlapping. Also here the tool and workpiece rotate in opposite directions.

Ceramic bond diamond and CBN cup wheels and respective finishing sleeves are used as tools. Depending on the workpiece volumes to be machined and the feed of the workpieces, different machine concepts are available with a horizontal and vertical design. On request we also produce customer-specific machines.

The range of workpieces includes the contact surfaces of planet gears and gearwheels, metallic sealing surfaces of components of injection pumps, ball pins and glide shoes of hydraulic construction parts, ball valves, ball pins used in vehicle construction and medical protheses.
