一前言 金属切削机床尺寸链的组成环和封闭环是矛盾的两个方面。在生产实践中,利用主轴尺寸链的组成环相互补偿使封闭环为零,以达到机床精度验收标准中规定的主轴锥孔中心线径向跳动允差要求。这种利用组成环相互补偿解决封闭环矛盾的办法,称为主轴径向跳动的角度选配法。这对 A preface Metal cutting machine tool chain composed of the size of the ring and the closed ring are contradictory two aspects. In production practice, the use of the main shaft size chain mutual compensation ring closed to zero, in order to achieve the acceptance criteria for precision machining spindle taper centerline radial runout tolerance requirements. This use of the composition of the ring to compensate each other to solve the contradiction between closed-loop approach, known as the spindle radial runout angle matching method. This pair
