Flachhonen - Doppelplanschleifen auf Peter Wolters Maschinen

flat honing or discus grinding

Discus grinding is used to machine components that place high demands on flatness and thickness tolerance.

The components to be machined are placed in externally toothed rotor disks (plastic, steel, etc.) and moved evenly by two pin rings over the horizontally arranged grinding disks. At the same time the grinding and rotor wheels are prompted. Different relative movements between the active parts are generated by rotation of the grinding wheels and the inner pin ring. This means cyclic trajectory curves are created.

In the case of rolled sheets, stamped, forged or cast components, hardened or tempered parts, stresses can be present in the material. Due to the simultaneous grinding of both outer surfaces, the released tension is neutralized, and the components are particularly flat after machining.

This processing method is suitable for flat parts from medium series, where special requirements are placed on the tolerance in thickness and flatness. Compared to conventional lapping our processing method significantly reduces machining times and enables comfortable cleaning of the workpieces.

Thanks to the tension-free mounting of the workpieces in the rotor discs, almost any solid material can be processed. The range of applications are plentiful. For example, bearing rings, spacer rings, sealing washers, sheets, barquettes and plates are reliably and precisely grinded to meet the highest quality standards.

material

The workpieces are shape-locked between the grinding wheels. This makes the grinding process is particularly suitable for non-magnetic metals in addition to magnetic steel:

  • Steel (soft, hard, hardened, tempered)
  • Stainless steel (V2A, V4A, Inox)
  • Hard metal
  • Titanium, nickel, silver
  • Non-ferrous metals (brass, copper, aluminum)
  • Ceramics
