Ondrives has recently taken receipt of an S21 grinding machine, designed for the grinding of workpieces in individual as well as small and large series production operations.

The S21 is suitable for grinding high-precision workpieces, as required by the aerospace, precision mechanics and hydraulic/pneumatic sectors.

The centre height of the unit bought by Ondrives is 125mm (4.9in) and the centre distance is 400m (15.7in).

There is a turret wheelhead that swivels automatically, a frequency controlled motor grinding spindle for external and internal grinding from 42,000-60,000rev/min and it is able to sense when about to touch on for grinding.

There is also automatic dressing of the grinding wheel using studiers latest software that brings a high level of functions to grinding operations that are not available on older machines.

This makes it a multi-functional machine for Ondrives’ grinding operations.

The workhead for universal use in live grinding operations and grinding between centres was of particular interest to Ondrives, and it decided to have the option of having a workhead specially designed for grinding chuck components also fitted so that every eventuality is covered where necessary.

There is a full enclosure with two sliding doors and the machine base is made of Granitan.

Ondrives can undertake all types of grinding work as well as other types of CNC milling and manufacturing.
