Coborn Engineering Co Ltd

RG9A - PCD Tool Production

Launched in 2016, the RG9A is a fully automatic, high precision grinding machine designed to meet the sophisticated demands of toolmakers working with both hard and ultrahard materials, such as carbides, ceramics, PCD and PcBN.Drawing on our 75 years of experience in designing machines for grinding and polishing diamond and related materials, the RG9A's construction ensures fast grinding times and repeatable accuracy to 2μm tolerances. The Coborn designed and manufactured wheel spindle is dynamically balanced to ensure minimal edge chipping of brittle and delicate tool materials. Programming is rapid, menu driven and straightforward for the operator and the ultra-fast vision system, with closed loop feedback, ensures minimum cycle times and maximum rates of throughput.The RG9A is ideal for tool manufacturers making both small and large batch sizes. Individual tool set up times are quick and, if required, robot loading is available. From simple, single point shank tools to helical/radius multi-point rotary tools, the RG9A has all the characteristics, functions and capabilities needed to minimize tool production costs.
