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 PG4 uses high quality air bearings for
both wheel spindle and the pivot which are
essential pre-requisites for controlled and
low waviness SCD tools. Programming is
extremely simple and minimal
The Coborn RG9A Laser Measuring
System is an optional extra which can be
purchased at point of sale or as an add-on,
retro-fit kit at a later date. This sophisticated
laser-beam measuring system can be used
to accurately reposition the RM Rotary axis,
in order to eliminate loading and brazing
errors giving you the exact geometry you
want. The laser uses a triangulation system
with aid from the camera to measure the
beam’s position and alter the machine’s axis
positions giving a high degree of accuracy
and precision, significantly improving
grinding results. training is required. It is an ideal machine
for SCD tool manufacturers who are looking
to minimise production costs and use their
skilled operators in more demanding areas.
PG4 ULTRA-HIGH PRECISION
SCD GRINDING
The PG4 is an automatic, ultra-high
precision grinding machine designed to
meet the most advanced requirements
of toolmakers working with natural or
synthetic single crystal diamond (SCD),
manufactured by either high pressure high
temperature (HPHT) or chemical vapour
deposition (CVD). The machine 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.
