Micro-optics grinding machine

The SPM-30 double high-speed tool spindle equipped grinding machine with optimum accuracy and surface roughness generates spheres of Ø up to 30 mm.

The Micro Series is the world-leading CNC manufacturing solution for micro-optics featuring air bearing spindle technology for up to 80,000 rpm. The optical micro machines include variety functions, one cycle pre- and fine-grinding, edging, chamfering, radial grooves and tool dressing.

The SPM-30 produces optimum surface quality. The grinding machine is easily handled by the operator using BaSyS, a user guided software interface.

Benefits and features

  • Precision processing
  • Air bearing spindles (up to 80000 rpm) and ball bearing spindle (up to 60000 rpm)
