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.
With tungsten carbide prices soaring 200%+, PCD & CBN become cost-effective alternatives. Moresuperhard provides high-quality PCD/CBN blanks, grinding wheels & grinders to help manufacturers reduce costs and improve efficiency.
A deep engineering analysis of vitrified diamond grinding wheels used for PDC cutters, covering grinding force, thermal damage, wheel clogging, self-sharpening behavior, and precision control solutions for high-performance drilling tool manufacturing.
