Precautions when using deep hole drill

1) The end face of the workpiece is perpendicular to the axis of the workpiece to ensure reliable end face sealing.

2) Before formal processing, pre-drill a shallow hole on the workpiece hole, which can serve as a guide and centering function when drilling.

3) In order to ensure the service life of the tool, it is best to use automatic tool feeding.

4) If the guide elements in the liquid inlet and the movable center support are worn, they should be replaced in time to avoid affecting the drilling accuracy.

 

Deep hole processing occupies a very important position in the field of mechanical processing, accounting for approximately 40% of the hole processing volume. The continuous emergence of new high-hardness and high-value difficult-to-machine deep-hole workpieces has led to continuous improvement in the processing depth, processing accuracy and processing efficiency requirements of the processed workpieces. As a key process and processing difficulty, only by mastering the concept of deep holes, deep holes Only by understanding the characteristics and difficulties of processing and having an in-depth understanding of the types, structures and usage ranges of various deep hole drilling bits can we better improve the efficiency of deep hole processing.
