目前在批量加工中至少有50％以上的刀具是用高速钢制造的。用PVD方法在高速钢刀具上涂上TiN涂层,是提高高速钢刀具耐用度的有效途径。涂层高速钢刀具具有优良的切削性能,已逐步推广应用于批量加工中,并初步取得了良好的经济效益。随着涂层高速钢刀具成本、价格不断降低,涂层质量不断改善,可以预期,今后在批量加工中会不断投入使用更多的涂层高速钢刀具。 At least 50% of the tools currently used in batch processing are made of HSS. Using PVD method to coat TiN coating on HSS tool is an effective way to improve the durability of HSS tool. Coating high-speed steel cutting tools with excellent performance, has been gradually applied to batch processing, and initially achieved good economic benefits. With the cost, cost and price of coated high-speed steel cutting tools and the continuous improvement of coating quality, it is expected that more coated HSS tools will continue to be put into mass production in the future.
