随着高速切削、强力切削先进技术的不断推广与提高,各厂巳广泛使用硬质合金车刀来代替高速钢和高碳钢。结构方面,目前虽有小部分采用机械装夹和切削力装夹,大部分仍采用焊接。因此,提高车刀的焊接质量可减少刀具消耗和降低产品成本。我厂对此进行了试验,并取得一定成绩。现将我们对接触钎焊工艺的几项改进介绍如下: 一、焊接工艺的制订焊接工艺的贯彻,是提高质量的重要环节。过去由于工艺规程不明确,操作者自搞一套,影响了质 With the continuous promotion and improvement of advanced technology of high-speed cutting and powerful cutting, carbide cutting tools have been widely used in various factories to replace high-speed steel and high-carbon steel. Structure, although a small part of the mechanical clamping and cutting force clamping, most still use welding. Therefore, improving the welding quality of lathe can reduce tool consumption and reduce product cost. I plant this test, and achieved some results. Now we contact the brazing process several improvements are described below: First, the development of welding process The implementation of welding process, is to improve the quality of an important part. In the past as the process is not clear, the operator set up a self, affecting the quality
