Subcontractor GB Precision has invested in a Studer S21 CNC grinding machine, which is suitable for use on high-accuracy components for the aerospace sector.

Micronz LLP supplied the S21 at the end of November and it is already proving its worth on many tasks, including the machining of bespoke thread forms with a maximum pitch error of 1.5 microns and the grinding of tapered polygons on the end of otherwise cylindrical geometric forms.

The machine also handles a range of high-precision grinding tasks for GB Precision, including the creation of external and internal spherical forms, often required for bearing races for aerospace components, where the surface finish across the whole part and the form accuracy is of critical importance.
