The embodiment of the invention provides a kind of method of machining screw, has adopted the lathe tool that provides among the embodiment 3, and shown in figure 12, this method comprises:
Step 101: adopt the grooving cutter cutter head on workpiece to be processed, repeatedly to process helicla flute, reach first order working depth up to the spiral fluted degree of depth with identical bite.
Particularly, adding body of tool each time comprises:
Grooving cutter according to bite radially vertical cut go out a helicla flute, in the degree of depth of bite helicla flute is carried out the left side successively and axially expands to cut and cut to expansion with right axis, process next helicla flute then.
Particularly, can the grooving cutter cutter head be installed on the knife bar, promptly obtain grooving cutter.
In this step, first order processing is divided into repeatedly machines again, the degree of depth/number of times of the spiral fluted degree of depth of each processing=first order processing is bite.Radially during vertical cut, the position of each feed is the centre position of screw thread to grooving cutter.For example the degree of depth of first order processing is 0.5mm, and then the spiral fluted degree of depth of each processing is 0.05mm, for the first time in the processing; Grooving cutter is first helicla flute of vertical cut radially; Radially the bite of vertical cut is 0.05mm, then this spiral fluted left side is axially expanded and is cut, and bite is 0.05mm; This spiral fluted the right is axially expanded again and cut, bite still is 0.05mm; First helicla flute of processing is the same together then, processes other helicla flute successively.Follow-up repeatedly add man-hour, still begin processing from first helicla flute, processing method is the same with processing for the first time.Adopt cutter head that the spiral fluted left side or the right are axially expanded when cutting; Have only the main cutting edge of cutter head to participate in cutting, avoided three of cutter heads to participate in cutting simultaneously, reduce the contact area of cutter head and workpiece with one of them front cutting edge; Reduce cutting resistance, strengthened the life-span of cutter head.

Particularly, the cutter head of grooving cutter is disassembled from knife bar, the roughing cutter head is installed on the knife bar, the roughing cutter head is processed workpiece then.
Step 101-102 has realized first order processing.
Step 103: repeating step 101-102 is the degree of depth sum of second level working depth and first order processing up to the spiral fluted degree of depth; Carry out the processing of next stage successively, up to the thread height-surplus of the spiral fluted degree of depth=screw thread to be processed.
Particularly, the process of remaining each grade processing all process with first order processing is identical, and just the spiral fluted degree of depth of each grade processing is different.
Through step 101-103, realize the roughing of double thread.In the roughing of screw thread, adopt radially vertical cut with axially about expand and cut the processing method that combines, avoided three of cutter heads to participate in cutting simultaneously, reduce the contact area of lathe tool and workpiece, reduce cutting resistance, the enhancing lathe tool life-span.And grooving cutter is in processing spiral fluted process, is degree of depth of vertical cut radially earlier, expands about carrying out axially to the helicla flute that cuts out then and cuts; Degree of depth of vertical cut radially again expands about carrying out axially then and cuts, through vertical cut radially repeatedly; The spiral fluted height is processed into identical with the height of the tooth form of screw thread to be processed, has avoided because the tooth form height is bigger, grooving cutter is when once radially the degree of depth of vertical cut is identical with the tooth form height; The iron filings that produce in the processing are discharged not smooth, and cutting resistance is big, easily breaking.And in the roughing of screw thread, adopt the alternately processing of grooving cutter cutter head and roughing cutter head, make that grooving cutter and roughing cutter head are not easy to wear, increased the life-span of cutter head.
Step 104: adopt the fine finishining cutter head that helicla flute is repeatedly processed, up to the thread height of the spiral fluted degree of depth=screw thread to be processed.
Particularly, the roughing cutter head is disassembled from knife bar, the fine finishining cutter head is installed on the knife bar.
