Are you having problems producing in-tolerance parts?
It is very likely that the root cause of the problem is your CNC machine tool.
Backlash, lack of repeatability, positioning and geometry errors may be
reasons your machine is producing parts out-of-tolerance. With the Renishaw
Laser Interferometer and QC10 Ballbar Systems we can analyze your machine and
in most cases isolate the problem on the first visit. In some cases we can correct
the problem on the spot and have your machine back up the same day.
