高精度,高效率成型磨削工艺是当前磨削技术发展的主要趋势之一,它可代替部分机加工的成型加工,从而节约大量复杂的工艺设备与投资,也可代替具有复杂表面形状的轴类零件(回转体)的多工序加工,并可达到所要求的复杂表面形状和相互位置精度。球销是我厂 EQ140,EQ240汽车之转向系的重要零件,目前,年生产纲领为近50万 High-precision, high-efficiency forming grinding process is one of the main trends in the current development of grinding technology. It can replace some machining and forming process, thus saving a large number of complex process equipment and investment, but also can replace the complex surface shape of the shaft Class parts (rotary) multi-process machining, and can achieve the required complex surface shape and mutual position accuracy. Ball pin is an important part of the steering system of our EQ140 and EQ240 cars. At present, the annual production program is nearly 500,000
