The following process measures can be taken during processing depending on the specific processing requirements:
(1) Before drilling, pre-drill a shallow hole with the same diameter as the drill bit, which can guide the centering when drilling. This step is especially necessary when machining small holes with high straightness requirements.
(2) When installing and debugging the machine tool, ensure that the center axis of the workpiece hole coincides with the center axis of the drill pipe.
(3) According to the material of the workpiece, the cutting amount is reasonably selected to control the degree of chip curling, and C-shaped chips which are favorable for chip removal are obtained. When machining high-strength material workpieces, the cutting speed V should be appropriately reduced. The amount of feed has a great influence on the formation of chips, and a small feed can be used under the premise of ensuring chip breaking.
