System Profiles PCD Tools On A Wire EDM

The PCD Edge System is said to allow quick and precise profiling of PCD cutting tools using a Fanuc iC series wire EDM. Available from Methods EDM, the system consists of programming/probing/cutting software, a micro-finish power supply for cutting PCD, a Hirschmann rotary axis, a Renishaw probe (mounted on the EDM) and a tool-clamping system. Suited for PCD tooling OEMs, contract sharpening services and shops that maintain their own tooling, the system can be used to create original profiles or to restore profiles on worn PCD-tipped tools. The system allows users to design tool edge contours on their own CAD systems, eliminating the need to learn a new system or change procedures. It provides special input masks to simplify parameter selection, program simulation, design modification and verification. With no special programming knowledge, the user can create as many as eight profile sections with specific parameters for each. The software and a rotary axis permit adjustment of the relief angles on each contour element as well as automatic measuring (with feedback) of 3D PCD tip positions such as rake and shear angles. With optional control software, the entire process can be automated for unattended operation.
