Description
Technical field
The present invention relates to processing thread arts, specially a kind of side using screw cutter cold in diamond processing screw thread
Method.
Background technique
Milling is carried out with disc milling cutter or Comb milling cutter on screw-thread miller.Disc milling cutter is mainly used for milling screw rod, snail
Trapezoidal external screw thread on the workpiece such as bar.Comb milling cutter is used for the inside and outside regular screw threads of milling and taper thread, due to being to use Multi-cutting-edge milling tool
Milling, its working portion length be greater than the length of processed screw thread again, therefore workpiece only needs to rotate 1.25~1.5 turns to add
Work is completed, and productivity is very high, and the screw pitch precision of thread milling generally can be up to 8~9 grades, and surface roughness is R5~0.63 micron,
The whorl work piece or the roughing before grinding that this method is suitable for producing general precision by batch.
The screw element machining internal thread to be processed, it is solid that screw element to be processed directlys adopt beam type one end too much
Surely carry out processing method, this causes to be easy to generate winding degree in processing, strong influence internal thread machining surface accuracy and
Roughness, secondly milling cutter uses hard alloy too much, and spontaneous hardness limitation, burr easily occurs in screw thread process face, and it is cut
It cuts three elements to be restricted, influences production efficiency.
Summary of the invention
The purpose of the present invention is to provide a kind of methods using screw cutter cold in diamond processing screw thread, on solving
State the problem of proposing in background technique.
The purpose of the present invention is be achieved a kind of to process using screw cutter cold in diamond by following technical proposals
The method of screw thread, comprising the following steps:

It carries out drilling processing, it is desirable that drill axis and the internal screw thread basic circle center of circle are in same horizontal line, and the diameter and internal screw thread to drill
Basic circle leaves enough machining allowance,
2) screw element to be processed after drilling is carried out coarse-fine bore hole twice to handle, bore dia and interior spiral shell after guaranteeing bore hole
Line basic circle is equal,
3) screw element to be processed after bore hole is fixed one by fixture, and centre frame is successively placed on screw thread to be processed
Part is fed on track, and centre frame is related with screw element length to be processed using number, generally increases by a centre frame every 200mm,
4) select No.1 diamond in cold screw cutter, by lathe main motion rotate milling cutter, screw element to be processed by
Screw rod, which drives, carries out feed motion, and internal screw thread basic circle is made to pass through milling cutter, and internal screw thread spiral groove depth is made to reach the processing of the first assistant warden
Depth, i.e. roughing depth, screw element amount of feeding f to be processed are equal to 2mm,
5) cold screw cutter in No. two diamonds is selected, continues to process screw thread processing, makes the depth of the helicla flute,
The depth of helicla flute is equal to part drawing and thread height 0.3mm, screw element amount of feeding f to be processed is required to be equal to 0.3mm,
6) by internal thread hole after processing is completed, the first layer screw pitch at both ends carries out coating treatment using TiC coating solution.
Cold screw cutter is relative to cold screw cutter anterior angle and tough inclination angle in No. two diamonds in the No.1 diamond
Smaller, relief angle is equal.
Described its screw position of screw element to be processed is not necessarily located in end face center, and by internal screw thread after processing is completed
The first layer pitch screw spiral groove depth at the both ends in hole is compared with remaining position depth 0.1-0.2mm, and by interior spiral shell after processing is completed
Pit need to store 20-30min and need to carry out coating treatment.
The beneficial effects of the present invention are: the invention is a kind of method using screw cutter cold in diamond processing screw thread,
It solves the problems, such as that internal thread machining is of low quality in the prior art, changes fixed form by increasing centre frame, effectively solve
Secondly the influence that the processing of winding degree internal threads generates changes motion mode by doing feed motion to screw thread process part, realize plus
Any selection of work screw position also makes disposably to process multiple screw threads on guaranteeing screw processing quality and become possible, using gold
Cold screw cutter in hard rock, machining internal thread surface quality, precision is higher, effectively removes machined burrs phenomenon, increased painting
Layer processing, can effectively prevent thread damage.
