Choose the SPM-50 CNC grinding machine for the production of small to midsized optics, from Ø 5 mm up to Ø 50 mm.




Best fit for combining the production of small AND midsized optics

SPM-50 features highest sensitivity for the handling of small lenses combined with best force required for processing larger diameters.

Efficient and flexible

  • The SPM-50 has been designed to be sensitive towards processing small lenses, without compromising on the force and robustness required for processing larger diameters.
  • Faster than expected, allowing pre- and fine grinding with one setup and minimal sub-surface damage.

Reliable and precise

  • It offers repeatable process performance through the improved machine and axes cooling that ensure an optimal and constant processing temperature during the grinding process.
  • The direct driven linear drives and servo motors ensure highest repeat positioning accuracy during processing.

Easy to use

  • Coated working chamber for fast and easy cleaning
  • Maintenance friendly
  • Compact footprint
