在磨削加工中,工件的粗糙度是主要的指标之一,在诸多因素中最主要的是外圆磨头的旋转精度。造成磨头旋转精度降低的原因中,最严重的是磨头烧伤。拉烧磨头的修复一般较困难,通过实践,我们总结了一些经验,较好地解决了上述问题。 1.磨头主轴的修复拉烧的主轴轴颈表面有密布的周向刻痕,有的深达几丝。一般工厂中没有超精磨床,只能研磨,但研磨工效低,而且不适于较深刻痕。为此,我们用超精
In the grinding process, the roughness of the workpiece is one of the main indicators, the most important factor in many factors is the rotational accuracy of the cylindrical grinding head. Caused by lower grinding rotation accuracy reasons, the most serious is the burn head. Pull the grinding head repair is generally more difficult, through practice, we sum up some experience, a better solution to the above problems. 1. Grinding head spindle repair Spinning spindle spigot surface with a circumferential notch, and some deep wire. General factory does not super-precision grinding machine, can only grind, but the grinding efficiency is low, and not suitable for deeper nicks. To this end, we use super fine
