The geometric shape of the cutting part of the through hole turning tool is basically similar to that of the outer circle turning tool. In order to reduce the radial cutting resistance and prevent the vibration of the turning hole, the main deflection angle should be larger, generally in the middle, the secondary deflection angle. In order to prevent the friction between the rear cutting face and the hole wall of the inner hole turning tool, the sum of two rear angles is generally taken. Take left and right. Blind hole turning tool is used to lathe blind hole or step hole, and the geometric shape of cutting part is basically similar to that of deflector. The main deviation angle is larger than, generally, the requirement of rear angle is the same as that of through hole turning tool. The difference is that the blind hole turning tool is clamped at the front end of the tool rod, and the distance from the tip to the outside end of the tool rod is less than the radius of the hole R, otherwise, the bottom surface of the flat hole can not be obtained.
