Sword is cut, each blade is in machining position there are one cutting edge, and by the improvement, blade has there are three cutting edge,
Blade position can be adjusted by mounting hole, the rotating blade when a certain cutting edge fails carrys out work using remaining cutting edge,
Blade overall utilization rate is high.
As a kind of improvement that also has of the present invention, the side of N number of chuck seat is at least one to be equipped with along chuck seat thickness
The auxiliary blade tool sip that direction is cut out, the auxiliary blade tool sip is interior to install auxiliary blade, the auxiliary of the auxiliary blade
Blade cut sword is exposed at outside chuck seat end face and is in assisted machining machining position, by the improvement, workpiece to be machined into
When to chuck screwer bottom, auxiliary blade can complete chamfering and either fillet or make the work of step or face work
Sequence exempts the additional process that will use tool sharpening chamfering either step or face work after piece-holder again, processing efficiency
The high concentricity for ensureing each working position simultaneously.
As a kind of improvement that also has of the present invention, the auxiliary blade cutter hub is equipped with multiple auxiliary blade cutting edges, institute
The auxiliary blade mounting hole being equipped in the middle part of auxiliary blade for making it be fixed on knife rest is stated, by the improvement, one of them
When auxiliary blade cutting edge fails, installs after auxiliary blade being rotated, added using other auxiliary blade cutting edge
Work improves auxiliary blade overall utilization rate.
As a kind of improvement that also has of the present invention, the quantity of the chuck seat is three, and the quantity is general hydraulic pressure card
The chuck seat quantity of disk, and three blades substantially meet cutting needs.
Second technical problem to be solved by this invention be：A kind of nothing is provided and needs to change cutter, process is simple, cutting effect
The chuck screwer that rate is high, blade life is high.
Second technical solution is used by the present invention solves the above problems：A kind of processing method of chuck screwer,
The method of the chuck screwer machining internal thread passes through following steps,
