Machine stability
The whorl milling cutter of certain brand, thread machining and go burr machines one knife to finish. Need not to go burr spends more time, restrict labour cost with season.
Finished cost is low
Whorl milling cutter is used agile, OK and applicable a variety of operating mode.
For example: We can be used same a whorl of Zun Xuan of treatment of whorl milling cutter, also can machine dextral whorl; The whorl outside can be being machined already, OK also the whorl inside treatment. All all these need to adjust interpolation program only just. Use tap is machined, if there are many different diameters on the spare parts but the whorl hole with same pitch, need the tap of different diameter. Such not only what require tap amount very much and the time that change a knife is much also.
If use whorl milling cutter, because use helix interpolation will undertake it machining, need to change machine program to be able to complete the treatment of the whorl of all diameters only so, charge of greatly economic cutting tool reachs the time that change a knife. To assure whorl precision, the need when processing different data with tap uses the tap of different type. Use whorl milling cutter not to have this limitation however.
Same a data that whorl milling cutter can process great majority and obtain very the whorl of high accuracy. Also can reduce cutting tool cost greatly so. When machining whorl to ask to be close to ministry of blind hole bottom, if use tap,tap general obtains complete whorl very hard in bottom. And be in likely attack bottom tap to stop preparation inverts time retreat the cutting tool in this paragraph of time to continue to move to was apart from ahead (float tap) , cause tap very easily to break off so.
Use whorl milling cutter can avoid this problem -- whorl milling cutter wants than aperture small need not invert retreat a knife, and be in cutting tool is most advanced remain complete whorl figure. Such we can obtain complete and accurate whorl deepness! In some treatment, whorl milling can help us solve a lot of problems.
For example: Be in large, in the thread machining of the spare parts that be not a circle, if be machined on lathe,with respect to need complex outfit is placed and shake in order to avoid generation evenly. Can use at this moment machine on machining center, the spare parts is not moved, whorl milling cutter rotates, avoid to balance a problem. Still have when machining spiccato whorl for instance, shake concussion to affect crackle of very large easy generation to bit. Use whorl milling cutter because cutting tool is,cut material gradually intermittent of place, avoided big impact so, prolonged cutting tool life.
