GB Precision has invested in a Studer S21 CNC grinding machine, making it one of only a handful of companies in the UK capable of offering out-of-round subcontract grinding.


This new machine has the ability to grind high-accuracy bespoke thread forms – often required for mould tool assembly work, and cut tapered polygons on the end of otherwise cylindrical geometric forms. In addition, the S21 also handles the whole range of high precision grinding tasks, including the creation of external and internal spherical forms, where the surface finish across the whole part and the form accuracy is of critical importance.
