随着科学技术的飞速发展,出现了多种难切削材料,它对金属切削刀具的性能提出了新的要求。本文就新型陶瓷刀具的应用与推广作一些肤浅的探讨。概况自1937年莱比锡春季博览会展出第一把陶瓷刀具以来,各工业发达国家不断进行了研究和切削试验。早期的陶瓷刀具主要是以冷压烧结制成的纯氧化铝陶瓷。我国在五十年代初,曾以冷压法制成白色陶瓷刀片,但太脆,抗震性差,不耐冲击,加上陶瓷中添加的强化材料与刀具几何参数选用不当,因此未得到广泛的推广应用。从六十年代末期起,我国更新了生产 With the rapid development of science and technology, a variety of difficult-to-cut materials have emerged, which put forward new requirements on the performance of metal cutting tools. This article makes some superficial discussions on the application and promotion of new ceramic tools. Overview Since the first ceramic tool was exhibited at the 1937 Leipzig Spring Fair, industrialized countries have continuously conducted research and cutting tests. Early ceramic knives are mainly made of cold-pressed sintered pure alumina ceramic. China in the early 1950s, once made by cold-pressed white ceramic blade, but too brittle, poor shock resistance, impatience and impact, coupled with the addition of ceramic materials and tool geometry parameters improper selection, it has not been widely promoted . Since the late 1960s, China has renewed its production
