In order to achieve the desired effect when using the deep hole drill, how can we improve its machining accuracy? Next by our staff to give you a brief introduction to its related knowledge.
Knowledge 1. It is necessary to ensure that the radial resultant force always presses the guide block and does not violate the direction of the guide block when changing the viewpoint and the width of the cutter teeth of the deep hole bit. The radial force should be neither too small nor too large. Too small radial force will weaken the guide of the deep hole bit and cause vibration; too large radial force will destroy the oil film of the guide block and make the guide block wear quickly. So we should pay attention to this question in deep hole drilling.
Knowledge 2: in the process of deep hole drilling, it is necessary to ensure the coolant flow and select the guide block material with good adhesion resistance, so as to avoid chip plugging and cutting adhesion on the guide block.
Knowledge 3: it is necessary to control the coaxiality error of spindle, guide sleeve and inner hole of connector less than 0.03mm.
