Mold machining center for deep hole processing, often the processing of iron chips wrapped around the tool, if not cleaned will be more and more tangled will even throw out. Some operators may say that it is 2 000 to remove them manually by hand or hook, but the iron chip temperature at high speeds will be very high and the operator will not be safe. In fact, we can be programmed to solve, after machining a hole to lift the spindle, and then the spindle reverse, so that the spindle tool can be thrown off the iron chips. This deals with iron chips but programming is cumbersome, every hole processed will have to change a spindle flip, and then turn forward, if a directive is missed, the consequences are serious.
Can also be deep hole with G83 shallow hole with G73, the amount of retract to small, choose a reasonable speed into the, in addition to the need to grind the turn head, so as to ensure that at least 30 or 40 holes in a row without iron chips winding, there is a little disadvantage of processing efficiency is a little lower, with G83 segment with a reasonable speed, iron chips can also be automatically thrown out, the premise is to close the processing center protection door.
