背景技术Background technique
在目前已有的技术中，轴承在各种机械结构中应用广泛，属于重要部件。随着时代的发展，人们对机械产品的寿命、稳定性和精度提出了更高的要求，这就为高精度轴承提供了广泛的市场。轴承滚道精度是轴承精度的重要指标。而车削是目前轴承滚道加工的常用方式。这也就对车削加工提出了更高的要求。同时，在车削轴承大直径滚道的过程中容易出现刀杆与轴承体发生干涉的情况。这种干涉会损坏刀具，乃至轴承、机床，从而影响加工过程，造成经济损失。In the current existing technologies, bearings are widely used in various mechanical structures and are important components. With the development of the times, people put forward higher requirements for the life, stability and precision of mechanical products, which provides a wide market for high-precision bearings. Bearing raceway accuracy is an important indicator of bearing accuracy. Turning is a common method for machining bearing raceways at present. This also puts forward higher requirements for turning processing. At the same time, in the process of turning the large-diameter raceway of the bearing, it is easy to cause interference between the tool holder and the bearing body. This kind of interference will damage the tool, even bearings and machine tools, thereby affecting the machining process and causing economic losses.
