Table 2 Classification by the degree of cutting tools failure
Rough machining does not require high cutting edge, and electrical machining or grinding can be selected. The electrical processing efficiency is high, and it is suitable for processing complex tools, such as drill bits for printed circuit boards, forming milling cutters for cutting laminate flooring, etc. Coarse-grained grinding wheel can be selected for grinding, with large contact area and high grinding force (300~400N) during sharpening, which can quickly remove excess machining allowance.
Polyetheretherketone PEEK has excellent comprehensive properties and can replace traditional materials such as metals and ceramics in many special fields. Moresuperhard has developed targeted grinding wheel formulas for the grinding of special engineering plastics such as PEEK, mainly electroplated grinding wheels, divided into rough grinding and fine grinding.
Diamond peripheral grinding wheels are used for peripheral grinding of PCD, CBN, carbide, ceramic, cermet and other indexable blades, flat blades, milling cutters, cutting blades, brazing blades, and machine clamp blades. At present, Moresuperhard peripheral grinding wheels have been successfully equipped with domestic and foreign mid-to-high-end peripheral grinding machines such as Hypertherm, Tiantong, Weize, WAIDA, EWAG, AGATHON, and WENDT, and have received unanimous praise from customers.
