The choice of rough boring cutter: most people do not attach much importance to rough boring cutter. It is often easy to ignore the importance of rough boring. In fact, the rough boring machining is very important. It directly affects the effect of the finishing process of the latter, which is embodied in the stable machining of the cutting after the rough boring. The choice of the rough boring knife should pay attention to the rigidity and easy operation of the boring cutter. A good rough boring cutter needs to be able to deal with the large cutting quantity and ensure the stability of the size of the aperture, so it is not guaranteed by a casual knife.
The choice of fine boring cutter: fine boring belongs to the Onomichi process of hole processing. The precision boring cutter has the function of precision and stability. The inner structure of the fine boring head determines the advantages and disadvantages of the fine tuning function of the boring head. The higher boundary of the fine boring head is that there is no backlash in the fine tuning. If the precision boring head has the reverse clearance, it will cause a lot of trouble for the precision boring processing, and it needs to be adjusted and confirmed repeatedly. Therefore, if a good boring head without reverse gap can be used, it is a great pleasure for the boring tool user.
