为了使铣削加工实现高效率、高质量和低成本,人们对陶瓷铣刀的应用进行了许多试验和研究。早在1936年,德国已经研制了装有纯氧化铝刀片,直径达400毫米的圆柱铣刀,当时由于材料的断裂强度太低,只用作塑料切削试验。1937年,在莱比锡博览会上,第一次展出了这种刀具。50年代中期,苏联试验了能加工灰铸铁的氧化铝多齿铣刀,其耐用度比硬质合金刀具提高了一倍。到60年代,东德采用装
In order to make the milling process to achieve high efficiency, high quality and low cost, people have carried out many experiments and studies on the application of ceramic milling cutter. As early as 1936, Germany had developed a cylindrical cutter with a pure alumina blade up to 400 mm in diameter, which was only used for plastic cutting tests due to the material’s low breaking strength. In 1937, the tool was exhibited for the first time at the Leipzig Trade Fair. In the mid-1950s, the Soviet Union tested an alumina multi-tooth cutter capable of processing gray cast iron, doubling its durability over cemented carbide tools. By the 1960s, East Germany used equipment
