高硬度球面磨削中球面形状误差分析与补偿

Spherical Shape Error Analysis and Compensation in Hard Sphere Grinding

为了提高高硬度球面磨削后的形状精度,分析了新型高硬度球面磨削机床中球面形状误差来源,针对实际加工过程中出现的鞍形球面,提出了采用退让式球面磨削的方法.实验结果表明:退让式球面磨削可以有效减小球面形状误差,对高硬度球面磨削具有实用价值.

In order to improve the precision of the spherical shape of hard sphere after grinding,the source of the spherical shape error in a novel hard sphere grinding machine tool was analyzed.The back-up sphere grinding was proposed for the spherical shape like saddle which appears more frequently in practice.The experimental results indicate that the back-up sphere grinding can decrease the spherical shape error effectively.It can benefit the hard sphere grinding greatly.
