大球面精加工和测量方法已受到机械制造业的密切重视。下面以球轴承的精密加工与测量为例作介绍。一、加工方法选用成型范成法磨削球面,主要是由于它的成型精度高,加工设备简单。但磨削过程中发热量多,冷却条件差,这可通过选择适当的磨削用量和冷却方式加以改善。图1为在M131W万能外圆磨床上加工球轴外表面的情形。床头加一套减速装置,使其头架转速范围为0.1—36转/分; Large spherical finishing and measuring methods have been closely attached to the machinery manufacturing industry. The following ball bearing precision machining and measurement as an example for introduction. First, the processing method selected forming Fan law grinding spherical, mainly because of its high precision molding, processing equipment is simple. However, the grinding process, more heat, poor cooling conditions, which can be selected by the appropriate amount of grinding and cooling methods to be improved. Figure 1 for the M131W Universal Cylindrical Grinder on the outer surface of the case. Bed plus a deceleration device, so that the first frame speed range of 0.1-36 rev / min;
