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.

The company has released its OpenCNC grinder for CNC ID, OD and centerless grinders. The grinder consists of hardware, software and documentation and has been engineered to meet the needs of machine builders, integrators, end-users and retrofitters who specialize in CNC grinding machines, the company says.

The grinder maintains the flexibility and power of open architecture, while providing ease of use and built-in features of a standard package, the company says. It is said to allow machine builders and end-users to easily upgrade or interchange machine hardware, software and peripheral components without having to re-engineer their existing machine logic.

The part programming features include: 11 wheel dressing routines, eight grinding sequences, advanced grinding wheel offset tools and an online help system. Each part program can contain as many as 20 grinding sequences.

The hardware/software package comes with wiring diagrams, documentation and pro-written PLC logic that allows machine builders or integrators to complete a control retrofit without having to spend weeks writing and debugging special machine logic, the company says.

Similar in appearance to its predecessor, the RG6, the Coborn RG8 wet grinding machine can control as many as 16 axes simultaneously. Also, its Windows-based software enables more multitasking than the previous model. This brochure provides technical specifications, photographs and a description of the product, which is distributed solely by Precision International Corp. in North America.
