Boring

Compared with other mechanical equipment processing, boring processing is a relatively difficult processing. It only needs to adjust one bit/(or bit holder/) to produce μm holes like H7 and H6. With the spread of machining centers in machining, boring is now only necessary for programming and twisting.

1. Tool rotation is different from CNC lathe machining, because the tool rotates during machining center, it is unlikely to immediately grasp the condition of the sharp knife during processing to adjust the amount of cutter. It is also unlikely that the machining diameter can be changed by simply adjusting the CNC machine twist, as is the case with machining centers. This becomes a considerable obstacle to fully automated processing.

2. Chatter The most common and headache problem in boring is chatter. The key reasons for flutter on machining centers are as follows:

3. Rigidity of the tool system software: including the stiffness of the collet, boring bar, boring head and part of its middle connection. Stub Boring is therefore very important for the machining of small round holes, deep holes and hard steel parts, where the stiffness of the tool system software is crucial.
