Are the typical figure, roughness and removal-rate values guaranteed for every optic?

No. Project guarantees must define material, surface form, clear aperture, data processing, wheel/fluid and FAT/SAT methods.

Can the wheel and abrasive system be changed?

50 mm is standard; 20 mm/150 mm are optional. Typical unit exchange is about 5 min, excluding cleaning/fluid replacement; recalibrate the ribbon and removal function.

What representative case is published?

170 mm spherical optic, R = 158 mm and edge tilt 32.55, improved from RMS 17.136 nm to RMS 1.655 nm. This applies only to the stated workpiece, fixture, process and data-processing conditions.

Product Q&A

Q:Can the PKC300-Q handle optics with steep slope curvature?

Yes, it offers extraordinary capability for steep slope optics, processing convex surfaces up to 90 and concave surfaces up to 60.

Q:How long does it take to switch between different polishing slurries?

With its mobile independent circulation system, the PKC300-Q allows users to switch between diamond and cerium oxide polishing slurries within 5 minutes.

Q:What is the axis configuration and precision level of this machine?

The PKC300-Q includes X,Y,Z linear axes and B,C rotational axes. Repeatability positioning accuracy is 8 um for linear axes and 8 for rotational axes,ensuring superior repeatability.

Q:What surface forms and sizes can be processed?

300 mm-class small- and medium-aperture flats, spheres, aspheres and freeforms. The nominal XY envelope is 300 * 300 mm; full-aperture feasibility depends on curvature, slope, workholding and collision clearance.

Q:How is steep-slope capability qualified?

X/Y/Z and B/C position and orient the workpiece. Approximately 90 convex and 60 concave are typical/project-specific; final reach requires part-specific accessibility and collision review.
