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:What surface types can the PKC300-Q finish?

It supports deterministic correction of flat, spherical, aspheric and freeform surfaces. The feasible aperture, radius, sag, local normal angle and workpiece mass must be evaluated from the drawing, fixture and collision envelope.

Q:How is steep-slope capability determined?

B/C mechanical rotary axes work with the software virtual A axis to orient complex surfaces. The reachable angle is not a single universal value; it depends on optic geometry, wheel diameter, fixture and tool-path strategy. A 3D feasibility review is recommended.

Q:Is the machine suitable for batch production?

Quick loading, multi-station handling, guided setup and automated calibration improve repeatability and reduce auxiliary time. Actual cycle time still depends on incoming error, required removal, substrate, wheel size, process route and metrology loop.

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.
