Abstract
The present invention is a kind of twist drill tool, particularly to the preparation method of a kind of rustless steel whole hard alloy tricuspid step drill cutter.Sequentially include the following steps: the selection of cutter material → cut and roughly grind → peripheral milling to put the first edge on a knife or a pair of scissors and open the back of the body → cutting tool dulling and process → detect outbound with surface.The preparation method of rustless steel whole hard alloy tricuspid step drill cutter is scientific and reasonable efficiently, enhances product performance further.
Description
Technical field
The present invention is a kind of twist drill tool, particularly to a kind of rustless steel whole hard alloy tricuspid step drill cutter
The preparation method of tool.
Background technology
When processing blind hole of the prior art or through hole, generally requiring because cutting performance is the best, machining accuracy is the highest.
Summary of the invention
The present invention mainly solves the deficiencies in the prior art, compact conformation, and lifting operation precision, uses ring
The multi-functional most advanced and sophisticated formula fluted drill of one that border suitability is high.
The above-mentioned technical problem of the present invention is mainly addressed by following technical proposals:
The preparation method of a kind of rustless steel whole hard alloy tricuspid step drill cutter, sequentially includes the following steps:
(1), the selection of cutter material:
1, for this difficult-to-machine material of processing stainless steel, the hardness of tungsten and cobalt sintering is selected to reach the hard of HRA86～93
Matter alloy material bar is main material；
2, according to cutter maximum diameter D16, the interior cryoprobe tool bar diameter of D16.3 is selected；
3, according to processing stainless steel material, select cobalt content higher, the preferably interior cold material of rigidity；
(2), cut and roughly grind:
1, according to cutter overall length 100, the bar hair training of 106 need to be cut；
2, by tool grinder, bar two is ground top；
(3), peripheral milling:
According to stairs of knives length and diameter, coarse-fine mill ladder and cylindrical, it is desirable to surface smoothness reaches Ra0.8 and notes retaining；It is coated with
Size and length BT0.2/100 of cutter back taper before layer；
(4), put the first edge on a knife or a pair of scissors and open the back of the body:
1, by special CNC five travelling wheelhead roll grinder, the fluting helical pitch of cold bar in calculating, control flume anterior angle 18 degree is also slotted；
2, measure blade angle by grooved, for the characteristic of stainless steel material, grind 48 degree of chisel edge angle, drill point angle 120 degree, protect
Protect cutter rib anterior angle 6 degree, relief angle 12 degree, C value 0.26, B value-0.63, R1 value 1, the long 1.2mm of chisel edge, chamfered corner length 1.2mm；
3, open unlucky seamed edge width 1mm and the seamed edge height 0.4mm that controls well, remove unnecessary back side surplus；
(5), cutting tool dulling processes with surface:
1, use cutting edge passivation machine that cutting edge does Passivation Treatment 0.07 on the cutter after putting the first edge on a knife or a pair of scissors；
2, to ground cutter, surface coated treatment is carried out；
(6), detection outbound:
Cutter is detected, without carrying out outbound after quality problems.
Therefore, the preparation method of the rustless steel whole hard alloy tricuspid step drill cutter that the present invention provides, preparation
Methodological science is rationally efficient, enhances product performance further.
