PCD cutters have high strength and impact strength, and only produce small grain breakage when the impact is large. Therefore, PCD cutters can be used not only for precision machining and ordinary semi-precision machining, but also for specific shapes to fit. With the development of PCD tool materials, Wald PCD tools have rapidly expanded to the manufacturing industry, and their high performance has replaced traditional hard alloys in the automotive industry. The special PCBN threaded insert is applied to the automobile cylinder liner in the automobile engine production line. The Wald PCBN insert has high precision, small surface roughness value and good stability. Due to the fast processing cycle of the production line, the cutting speed of the PCBN insert is high (usually V≥500m/ Min), the tool life is long (the number of machining holes is ≥1000), and the blade life of multiple stations such as chamfering, stop, coarse and fine, should meet the durability requirements. High-speed cutting and high-stability machining of engine cylinder bore can be realized by PCBN tool. Typical cutting parameters are: V=500m/min, f=0.2～0.4mm/r, ap=0.2～0.7mm; machining surface roughness Ra≤1.6μm, tool life>1,000 pieces. The Wald PCD inserts are dedicated to wind turbine rotor blades DFT & DFS and are drilled at the fan blade joint.
