GAS / GIS / HGS

special solutions

GAS
Machines from the GAS model range are used for processing external threads and similar profiles. Typical components for these machines are external ball screws for automotive steering systems, as well as drive worms and small pumps and metering components. In line with the shaft-type geometry of the components, these machines are designed with a horizontal workpiece axis and have correspondingly long travelling paths. Parts are machined by discontinuous profile grinding only; the tool concept is adapted to the corresponding component requirements:

  • non-dressable CBN profile grinding wheels
  • dressable ceramic grinding wheels

For specific applications, various tools can also be combined.

GIS
Machines of this type are used for the hard and soft finishing of internal threads in ball screw tracks or similar profiles. Typical applications besides vehicle steering are recirculating ball screws in the field of automotive.

Parts are machined by discontinuous profile grinding.

Non-dressable CBN profile grinding wheels are exclusively used, typically in a combination of roughing and finishing tools.

HGS
The high-speed grinding machine HGS is mainly used for grinding slots in pump rotors into the solid, through-hardened material. Slot widths of 0.5 to 2.0 mm can be produced with high efficiency due to package clamping and automatic unloading and loading. The in process measuring control ensures maintaining slot width tolerances.

The HGS uses non-dressable CBN profile grinding wheels only.
