A Kellenberger CNC universal grinder is now in operation at Yeovil-based PDQ Precision, a specialist in the provision of subcontract machining services to sectors such as aerospace, medical, motorsport and packaging.

“Although we have earned a reputation as a comprehensive one-stop-shop machining facility, if we have a speciality it’s in the area of precision grinding,” explains managing director Martin Thrower. “To enable our grinding section to keep pace with ever increasing demand we recently searched for an efficient universal CNC grinding machine able to produce high-accuracy work. In addition, as we generally grind relatively small volumes, we looked for a flexible machine with quick set-up capabilities.

“Although a couple of the universal CNC grinding machines we scrutinised satisfied certain aspects of our needs, it was only a Kellenberger model that fulfilled all of them,” continues Thrower. “Our new universal CNC grinding machine is now delivering on all the promises made and producing the required large volumes of high-quality components.”

The Kellenberger’s Z-axis movement uses traditional guideways that guarantee a high degree of damping, while the machine’s X-axis movement utilises roller guideways which deliver non-stick/slip positioning. Heidenhain high-precision nano-resolution linear scales feature in both axes. The space-efficient grinder offers one internal and two external spindles, selected via a programable B axis. A swivelling workhead makes the machine suitable for both grinding between centres and chucked work, with further flexibility provided by a manually operated swivelling upper table.

The grinder’s wheel-head exhibits thermal stability thanks to the use of optimised spindle bearings and water-cooled motors. Control is via a FANUC 0i CNC.

Kellenberger’s entire grinding machine range is exclusively available in the UK and Ireland through DF Precision Machinery.
