PPM 250 CNC

CNC-Controlled 5-Axis Polishing Center for Optics up to Ø 450 mm 

 

 

Highlights:

  • Maximum flexibility due to 5 CNC axes
  • OptoTech Reverse Technology (ORT): Reverse arrangement of the tool and the workpiece. The is held in the upper spindle during the polishing process and allows for working pressure to be applied, or for polishing to be done without any working pressure using just the workpiece's own weight. This produces much better surface accuracy compared to those achieved with the conventional configuration
  • High Dynamic Digital Drives for all axes
  • AST: Advanced Setup Technology (Touch Setting)
  • Options: Second Tool Spindle with separate Z-Axis for the Dressing Tool; Hydro Expansion Chuck HD 40; HydroSpeed® Polishing Technology

 

Range of Application:

Polishing of high performance optics for use in lithography and semiconductor optics. Production of plano surfaces (plano plates, prisms); Spherical surfaces (lenses); Aspheres; Optical freeform surfaces
