OLP40 lathe touch probe

For workpiece inspection and job set-up on lathes of all sizes and small multi-tasking machines.

Flexible probing solution.

Reliable modulated optical transmission.

Outstanding performance for less scrap and higher profits.

Ultra-compact probe

Ultra-compact 3D touch-trigger probe with optical signal transmission, specifically designed for workpiece set-up inspection on lathes and grinding machines.

Compatibility with all Renishaw optical receivers enables users to easily upgrade existing installations.

Features and benefits:

  • Proven kinematic design.
  • Exceptional resistance to light interference with modulated transmission.
  • 360° transmission envelope.
  • Ultra-compact design.
  • Increased environmental protection.
  • 1 μm 2σ repeatability.

On one component we used to spend 35 minutes on in-process inspection – this had to be improved. We replaced this with a probe cycle, reducing the inspection cycle to about six minutes.
