Grinding & spark machining

Spark machining is a technique that uses electrical discharge. It offers the advantage that all materials that conduct electricity can be processed. The greatest advantage is that it is possible to process hardened materials. It allows simple 2D forms and even complex 3D forms to be processed.

Both cylindrical grinding and surface grinding are applied to optimise accuracy. For example, grinding after a hardening process, concentric diameters, with no impact, etc.
