随着机床生产一日千里的发展,切削刀具的生产也应該相应地加以解决,特别是在机械工业大搞小土群以来,刀具的需要量将大量增加。在这样一个形势下,我們进行了以球墨鑄鉄和高硫可鍛鑄鉄(通称土球墨鑄铁)制造刀具的試驗,經試驗証明可以用它来加工鋼材和鑄鉄,并可以保持一定的耐用度。只是切削速度不能太高,这一点需要我們在使用中继续研究改善。目前試制的鑄铁車刀有以下四种: 1.經过热处理的球墨鑄鉄車刀:用普通球墨鑄铁浇
With the rapid development of machine tool production, the production of cutting tools should also be resolved accordingly, especially in the machinery industry to engage in small soil groups, the tool will greatly increase the demand. In such a situation, we have carried out tests on ductile cast iron and high-sulfur malleable cast iron (commonly known as earth ductile iron), which have been tested to prove that steel and castings can be processed and retained Durability. Just cutting speed can not be too high, this point we need to continue to study and use in improving. The current trial of cast iron turning tools have the following four: 1. After heat treatment of ductile cast iron turning tool: cast with ordinary ductile iron
