GBP 57 D Diamond grinding points − brazed metal bonding Precision-ground blanks with diamond application in vacuum brazing processes. Advantage: ■ More free-cutting than galvanically bonded grinding points due large grit projection (about 70% of the grit projects from the bonding material) and stronger bonding. ■ The open structure and coarse D427 grit reduce the grinding temperature and minimise the tendency to clog up. Application: For hand-held use, on industrial robots or CNC grinding machines for rough grinding work with high material removal rates. Side milling, contour milling of composite materials (CRP/GRP), fibreglass, graphite, honeycomb. Note: Other grit grade, special shapes or grinding points with internal cooling for stationary use are available in request.
