FAQs
We typically achieve ±0.002 mm tolerance with PG optical profile grinding.For simpler geometries or specific critical features, tolerance can reach to ±0.001mm. Final capability depends on part geometry, material, and profile complexity.
We typically grind radii as small as R0.02 mm (tool steel) and R0.01 mm (carbide).
All sharp corners are produced with a controlled micro-radius for durability and performance.
Yes. We specialize in complex and asymmetric PG-ground profiles, including compound curves and non-symmetrical shapes.

PG optical profile grinding provides significantly higher profile accuracy and repeatability than standard grinding, especially for parts with complex contours and functional edges.
Compared with standard grinding, PG grinding offers:
Superior profile accuracy for curves, angles, and asymmetric shapes
Direct optical profile verification during grinding
Cleaner, sharper cutting edges with controlled micro-radius
Better consistency across multiple identical parts
Standard grinding is well suited for straight surfaces and simple geometries.
However, when the function of a punch or insert depends on precise contour shape, PG optical profile grinding ensures the profile matches the design intent exactly.
For precision molds, connector tooling, and fine-pitch stamping applications, PG grinding often results in more stable performance and longer tool life.
