一、前言刀具前角测量仪,实际上是个简单的检验夹具,原系用作检验丝錐前角的。笔者考虑,它的使用范围远不止此,因此给它这样一个名称。我们知道,前角是任何切削刀具最重要的角度之一,它对于切削速度、刀具寿命、切削力的大小等有很大关系,亦即对提高生产率有极大意义。前角无论是大了或小了,都会严重地影响到劳动生产率,是不合乎我们要求的;对于高速切削的硬质合金或陶瓷刀具更是如此。保证刀具前角是保证劳动生产率(尤其是稳定)的重要因素之一,但目前有些工厂没有重视这
First, foreword Tool rake angle measuring instrument, in fact, is a simple test fixture, the original for testing tap rake angle. The author considers that its scope of use goes far beyond this, so give it such a name. As we know, the rake angle is one of the most important angles of any cutting tool. It has a great relationship with the cutting speed, the tool life and the cutting force. That is to say, it is of great significance to improve the productivity. Whether the anterior horn is large or small, will have a serious impact on labor productivity, is not in line with our requirements; for high-speed cutting cemented carbide or ceramic tool even more so. To ensure the tool rake angle is to ensure that labor productivity (especially stable) one of the important factors, but some factories do not attach importance to this
