一、问题的提出小孔磨削时,由于受砂轮直径的限制,砂轮线速度达不到一般正常磨削所要求的线速度,磨削效率低,磨削力大,效果差。此外,还存在砂轮磨损快,耐用度低,自励性差,工件易烧伤等缺点。可见,在现有常规设备上进行小孔磨削的难度很大,必须寻求新的解决办法。 First, the issue raised hole grinding, due to the limited diameter of the wheel, grinding wheel linear speed less than the normal normal grinding required linear speed, low grinding efficiency, grinding power, poor results. In addition, there are shortcomings of wear fast wheel, low durability, poor self-motivation, easy to burn the workpiece. It can be seen that it is very difficult to grind small holes on existing conventional equipment and new solutions must be sought.
