在生产中,常遇到图1类型的零件。其圆弧型面加工的传统方法是在平面磨床上先用挤光刀(图2)将砂轮圆周面挤出圆弧为R的凸型面,再以此型面砂轮来磨削零件,达到技术要求。但是,上述这种挤压砂轮的方法有明显的缺点: 一、工人劳动强度大。使用挤光刀时,被挤砂轮须低速旋转(每分钟数拾转,高于此速,会磨坏挤光刀)。操作时砂轮向挤光刀作垂直缓动送进,靠接触面的压应力将砂粒逐渐挤掉,而获得所需的砂轮型面。但平面磨床的
In production, often encounter the type of Figure 1 parts. The traditional method of arc-shaped surface machining is to use a squeegee (Figure 2) on the surface grinder to extrude the circular surface of the grinding wheel into a convex surface of circular arc R, then grind the parts with the surface-grinding wheel to achieve the technical Claim. However, the above method of squeezing the grinding wheel has obvious shortcomings: First, workers are labor-intensive. When using a squeegee, the squeezed wheel to be low-speed rotation (revolutions per minute pick up, higher than this speed, will wear crowded knife). When operating the squeegee to squeeze the knife for vertical slow feed, by the contact surface of the compressive stress will gradually squeeze out the sand, and get the desired wheel profile. But the surface grinder
