RE-GRINDING AND RE-COATING Re-grinding and re-coating Guhring provides a life-long re-grind and re-coating service for thread milling cutters. By professionally re-grinding and re-coating with original geometries and original coatings Guhring re-produces the 100 per cent tool efficiency. Re-grind service In our service centres, tools are re-ground on the front rake face according to the degree of wear. According to width of wear marks the re-grind service is possible two or three times (from milling part diameter d1 > 5.0 mm). In order to re-define the milling portion diameter, the number of re-grinds is indicated by a notch on the end of the shank. This means every notch is assigned to a diameter and re-etched. Re-coating If a thread mill was enhanced with a coating, the tool is re-coated following the re-grind. This way, not only the wear-and corrosion-protection as well as the glide characteristics are re-produced but also the tool life prolonged. GUHRING 821 Technical section
