我们在无心磨床上加工电动式扬声器里的磁极芯零件时,因工件的直径接近于或大于长度,因此,时常由于跳料“啃”伤磨削轮而影响生产,还可能发生人身及机床事故。针对以上问题,我们用4～5毫米厚的中碳钢板制作了一个防跳挡板(见图示),把它安装在导轮架转体前端面装冷却液护板的螺孔上,不仅能防止跳料,又能增加磨削量,提高生产效率、效果很好。应该指出,挡板使用部分的宽度应宽于磨削轮(进料口与出
When machining magnetic pole components of electric speakers in a centerless grinder, the diameter of the workpiece is close to or greater than the length. Therefore, it often affects the production due to the “gnawing” injury of the grinding wheel, and personal and machine accidents may also occur . In response to the above problems, we use a 4 to 5 mm thick carbon steel plate made of a baffle (see the picture), it is installed on the front end face of the guide wheel bracket mounted coolant guard plate screw holes, not only To prevent the hopper, but also increase the amount of grinding, improve production efficiency, the effect is very good. It should be noted that the width of the baffle section should be wider than the grinding wheel (inlet and outlet
