我厂是国内生产杂质泵的专业厂,杂质泵的主要材料为高硬铸铁和其它耐磨材料。这些材料经热处理后硬度为HRC 50～64,给机械加工带来许多问题。以前,采用硬质合金刀具加工,切削速度仅为10米/分左右,车出的工件尺寸带锥度,尤其是对止口的加工、刀尖磨损快,更难保证精度。成为机械加工的关键。从1983年开始,我们试用湖南冷水江市陶瓷工具厂生产的陶瓷刀片后,取得很好的使用效果。改为陶瓷刀具后,切削速度为80～100米/分,工效成倍提高,使多年来的老大难问题基本得到解决。
Our factory is a professional factory producing impurity pump in China. The main material of impurity pump is high hard cast iron and other wear-resistant materials. These materials after heat treatment hardness HRC 50 ~ 64, to bring many problems machining. In the past, the use of carbide cutting tools, cutting speed of only 10 m / min or so, the car out of the workpiece with a taper, especially for the processing of the mouth, the tip wear fast, more difficult to ensure accuracy. Become the key to machining. Since 1983, we have tried our best to use the ceramic blade produced by Hunan Lengshuijiang Ceramic Tools Factory. To ceramic tools, the cutting speed of 80 ~ 100 m / min, work efficiency increased exponentially, so that over the years the basic problems have been resolved.
