Chip removal mode of deep hole cutter

Because the deep hole tool adopts the internal chip removal working mode, the oil is supplied from the outside of the boring bar. After passing through the guide bar and cutting edge, it turns back and carries the chips from the boring bar cavity and discharges them back, realizing the full cooling and lubrication of the boring head cutting edge and guide bar. On this basis, the cutting edge and guide bar can be made of superhard tool materials freely to achieve high-speed and high-precision deep hole boring.
There are mainly CNC production drilling machines, deep hole drilling machines, etc., which have completed drilling, reaming, hole comparison, boring, tapping and other processes; The hole cutting tool is applicable to the production of parts with certain accuracy requirements for the distance between holes.  
For deep hole cutters, its application brings convenience to the majority of users, and also improves the qualification rate of products. Some users may not understand this very well, so let's have a brief understanding. I hope our explanations can help you better understand and understand, as follows:
In general, we know that the feature of deep hole cutters is to reduce the precision requirements for the guide sleeve of the machine tool. The adjustable ball size can effectively control the fitting clearance between the tool and the guide sleeve, reduce the requirements for the dimensional accuracy of the inner hole of the guide sleeve, and avoid the problem that when the fitting clearance between the conventional TGG boring roller head and the guide sleeve is too large, the thread occurs in the processing of the inner hole, which can effectively improve the processing quality of the inner hole.
The technical requirements of its products for operators are reduced. For the workpieces with unsatisfactory processing size, secondary processing can be carried out by adjusting the rolling amount, which can effectively control the scrap rate.
