In the process of deep hole drilling, there are many problems, such as the dimension accuracy, appearance quality and tool life of the machined parts. How to reduce or even avoid these problems is the problem we need to deal with now. The following summarizes the problems and treatment methods of reducing the diameter of CNC deep hole drilling machine.
The reason why the diameter of the CNC deep hole drilling machine is reduced is that the axis is different from that of the workpiece, and the force of both hands is uneven when reaming the hole, which makes the reamer shake left and right. The results show that the planning value of the outer diameter of the reamer is too large or there is burr on the cutting edge of the reamer; the flat tail of the unsuitable taper shank is selected and installed into the main shaft of the machine tool; the taper of the taper shank interferes with the taper interference; when the reamer is installed, the oil stain on the surface of the taper shank is not cleaned or the taper surface is bumped.
CNC deep hole drilling machine three-axis feed drive adopts servo motor and driver, and is directly connected with ball screw, transmission is stable, no backlash. At the same time, its good rigidity and optimized shock absorption performance greatly improve the dynamic rigidity of transmission system and realize rapid movement. Heavy load, high-speed, high-precision ball linear guide ensures high-precision processing and prolongs the service life of the linear guide.
