PG4 Curve Block Software | Coborn Engineering

PG4 Curve Block

Coborn is introducing the new Curve Block Software for the PG4 Planetary Grinding Machine. This optional feature allows grinding of elliptical, parabolic, hyperbolic and cubic profiles.

The PG4 Curve Block Software is ideal for tool manufacturers in the electro-optics industry and is intended to facilitate the production of complex profile tools. The software can be purchased at point of sale or can easily be added remotely at a later date. Please contact  for further details or a quote.

The PG4 is an automatic, ultra-high precision CNC grinding machine designed to meet the most sophisticated of demands from toolmakers working with natural or synthetic single crystal diamond (SCD), manufactured by either high pressure high temperature (HPHT) or chemical vapour deposition (CVD).

The PG4 now enables many of the laborious and time consuming processes, such as blocking out, to be fully automated and the subsequent final radius polishing to be completed without human intervention. The machine uses high quality air bearings for both wheel spindle and the pivot which are essential pre-requisites for controlled and low waviness SCD tools. Please go to  for more information.
