Blade Grinding & Edge Sharpening
Surface and profile grinding for blade edges. Single-bevel, double-bevel and chamfered profiles to Ra 0.4.
- Surface grinding for flatness on sealing dies and shear blades
- Profile (form) grinding for slitter blade edge angles
- Edge angle range 15° – 45°, customer-spec
- Surface roughness Ra 0.4–1.6 routinely
Edge geometry is the second half of “blade life”. After heat treatment and wire-EDM the blade still needs a true ground edge — surface grinding for flatness and profile grinding for the bevel angle. We hold edge angles to ±0.5° and surface finish to Ra 0.4 on the working edge.
