Manual Radius Grinding Machine for PCD and PcBN tools
The RG5B-XD is the latest in a very successful line of RG machines made by Coborn Engineering in the UK. The machine is unique in terms of strength and rigidity - both are essential for grinding diamond under high grinding pressures.
Many of the machine parameters are controlled via the touch screen. Tools are made in a series of steps e.g. grind facet left, grind facet right, grind radius between facets. Parameters for each step or "block" are saved to the internal PC.
Parameters are: wheel direction, wheel position, wheel speed, wheel stroke length. A tool program is thus made up of a series of such blocks. Programs, once written can be re-called of course or modified as required.It is thus a semi-automatic machine.
The tool image can be inspected using a projector (as on the machine above). Alternatively, a camera/vision system (VS5-G, see below) can be fitted. The image from the camera then appears on the touch screen.
