After air hardening we use high-precision grinding equipment for optical-quality surface and close-toleranced dimensions. Cylindricity deviation after finishing is within 1 micron.


Soft embossing rolls

They are also steel rolls, but have special plastic cover with unique mechanical properties. Combination of hardness and compliance provides the quality of hard with the versatility of soft embossing.
