Out-of-Round Grinding Capability give GB Precision the Edge

GB Precision has invested in a state-of-the-art 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 – a growing requirement for the complex high-accuracy components for the Aerospace sector.

“More and more customers are asking us to grind components which include micrometer-class threads or out-of-round geometries,” explains GB Precision MD, Paul Turner, continuing; “We purchased our first Studer CNC machine almost a decade ago and it has been producing first class precision parts ever since, so we knew where to turn for an additional machine to tackle these new challenges.”

The new S21 was commisioned in November and is already proving its worth on a number of tasks including the machining of bespoke thread forms, with a maximum pitch error of 1.5 microns, which are required for a complex mould tool assembly, as well as the grinding of tapered polygons on the end of otherwise cylindrical geometric forms.

In addition to tackling these most challenging jobs, the machine also handles the whole range of high precision grinding tasks for GB Precision, including the creation of external and internal spherical forms, often required for bearing faces on aerospace components, where the surface finish across the whole part and the form accuracy is of critical importance.
