Is there a standard for drilling errors due to machine tool shaking?
But the drill is drilled out of Kong Shizheng because the bit will wobble during drilling so that the drilled hole is out of turn.
Is the drill drill a positive or negative deviation, or is it bigger or smaller?. Bit wear is not serious, the drilled hole is a positive deviation. If the drill is used for a long time, the ligament is worn badly and the drill is worn out too, and the hole drilled is a negative deviation
There is no standard for the drill hole error due to machine tool shaking.
