一、概述 BPH300型矩台卧轴平面磨床是五十年代捷克的产品。经二十多年使用,精度下降,被加工零件波纹度大,最高加工光洁度为▽8。生产中被加工件的光洁度一般要求在▽9以上,故需增加研磨工序。将该磨床的磨头由动压轴承改为小孔节流液体静压轴承后,不用冷却液磨削,工件光洁度可达▽10。在横向进给相同的情况下,最大屹刀量从0.2毫米提高到0.3毫米。如果把皮带轮改为卸荷装置,减少电机振动对主轴的影响,加以适当的冷却液,估计光洁度还可提高一级。
First, an overview BPH300 Rectangle horizontal axis plane grinder is the Czech Republic’s products of the fifties. After more than twenty years of use, the accuracy is reduced. The waviness of the processed parts is large and the highest processing finish is ▽ 8. Production of finished parts of the finish is generally required in ▽ 9 above, it is necessary to increase the grinding process. The grinder grinding head from the dynamic pressure bearing small orifice throttled hydrostatic bearing, without coolant grinding, workpiece finish up to ▽ 10. In the same case of horizontal feed, the maximum amount of force increased from 0.2 mm to 0.3 mm. If the pulley into the unloading device to reduce the impact of motor vibration on the spindle, to be appropriate coolant, the estimated finish can also be increased by one.
