A kind of processing method of deep via, fixture is fixed with knife bar, multiple cutters are uniformly fixed on to the surrounding of fixture, on fixture, the rear side processing water-cooling groove of cutter, the distance between the top of cutter and fixture outer shroud are 10mm 12mm, and the distance between the bottom of cutter and fixture inner ring are 10 12mm.High-pressure water pipe is connected in the rear end of knife bar, then starts to process deep via, the rotating speed of knife bar is 130 150 revs/min, and feed speed is 10 20mm/ hours.While knife bar works, water under high pressure is passed through, water under high pressure is flowed between workpiece and cutter, reserved from water-cooling groove, circulating cooling is carried out to cutter and workpiece, while going out metal fragment.The present invention is simple in construction, it is adaptable to process deep via, operating efficiency can be provided significantly, through practical operation, same hole is processed, than the time that traditional diamond-making technique can save more than half；And cooled down in process, the metal fragment of generation greatly reduces, and the metal bar processed can also be recycled.
Description
Technical field
The present invention relates to a kind of machining tool in hole, especially a kind of instrument for processing deep via.
Background technology
Current hole forming method, is to be cut using boring machine or drilling machine mostly, can produce substantial amounts of metal fragment, wasted
Material also is difficult to sweep；And process velocity is very slow, particularly with the processing of large-scale deep hole, generally require to process up to a hundred hours
It can complete.For processing deep via, cooling is very crucial, and the effect of cooling directly affects the efficiency of processing, existing
Deep via machining tool cooling effect it is general.
The content of the invention
For above-mentioned the deficiencies in the prior art, hole machined work is mastered the invention provides one kind is simple in construction, efficient
Tool.
To achieve the above object, the technical solution adopted by the present invention is：A kind of instrument for processing deep via, including knife bar,
Fixture, cutter, high-pressure water pipe and water-cooling groove.Described knife bar, fixture and high-pressure water pipe is hollow structure.The fixture is fixed on
The front end of knife bar, high-pressure water pipe is fixed on the rear end of knife bar.Cutter is fixed on the front end of fixture, the top of cutter with outside fixture
The distance between ring is 10mm-12mm, and the distance between the bottom of cutter and fixture inner ring are 10-12mm.Water-cooling groove is in
The rear side of cutter.
It is preferred that, described knife bar is provided with antivibration pump.
It is preferred that, on described fixture, the rear side of cutter be provided with hole boring cutter, peak high 0.2- of its peak than cutter
0.4mm。
It is preferred that, described hole boring cutter material is high-speed tool steel.
The present invention is simple in construction, it is adaptable to process deep via, operating efficiency can be provided significantly, through practical operation, processing
Same hole, than the time that traditional diamond-making technique can save more than half；And cooled down in process, the metal of generation
Chip greatly reduces, and the metal bar processed can also be recycled.Using this tool processes deep hole, compared to existing
Drill bit, reduces the contact area in boring procedure, substantially increases the efficiency of drilling, and because blade stability is good, leads to
Cross the hole that this instrument comes outbreak out, hole wall is round and smooth, and finish can reach more than 6.3, can by blank core completely extract one
Bar, the diameter of bar only than the small 20-30mm in hole for needing to process, the scope of application for need deep hole processing diameter 100mm with
On metal stock.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
As Figure 1-Figure 4：A kind of instrument for processing deep via, including knife bar 1, fixture 2, cutter 3, high-pressure water pipe 5, water
Cold trap 8 and hole boring cutter 9.Described knife bar 1, fixture 2 and high-pressure water pipe 5 is hollow structure.The fixture 2 is fixed on knife bar 1
Front end, high-pressure water pipe 5 is fixed on the rear end of knife bar 1.Cutter 3 is fixed on the front end of fixture 2, the top of cutter 3 with outside fixture 2
The distance between ring is that h1 is 10mmm, and the distance between the bottom of cutter and fixture inner ring h2 are 12mm.Water-cooling groove is in knife
The rear side of tool.Hole boring cutter 9 is arranged on fixture 2 and the rear side in cutter 3, between its peak and the peak of cutter away from
It is 0.2mm from h3, in order to bore hole.Described knife bar 1 is provided with antivibration pump 4.
One 6 meters long, a diameter of 200mm through hole is processed on workpiece, first from hollow knife bar 1 and fixture 2,
Fixture 2 is fixed with knife bar 1, both total lengths are 6.3 meters.Four cutters 3 are uniformly fixed on to the surrounding of fixture 2, in folder
On tool 2, the rear side of cutter 3 processing water-cooling groove 8, the distance between the top of cutter 3 and the outer shroud of fixture 2 h1 are 10mm, cutter 3
The distance between bottom and the inner ring of fixture 2 h2 be 12mm, this distance while guaranteeing to obtain maximum metal rod 7,
Water cooling can be sufficiently carried out, and processing is got up easily；High-pressure water pipe 5 is connected in the rear end of knife bar 1, then starts processing
Deep via.While knife bar 1 works, water under high pressure is passed through, water under high pressure is flowed between knife bar 1 and metal bar 7, from water-cooling groove 8
Reserve, circulating cooling is carried out to cutter 3 and workpiece 6, while going out metal fragment；After drilling through, by the metal bar 7 in workpiece 6
Take out, complete the processing of deep via.Described knife bar 1 is provided with antivibration pump 4.The height of antivibration pump 4 is slightly below folder cutter 3 most
High point, because hole depth is larger, rocks if knife bar 1 is anti-raw during brill, the position that cutter 3 is bored can be caused to occur deviation,
It may result in that hole wall is sufficiently oily, antivibration pump 4 can set multiple according to the depth of drilling.Fixture 2 is provided with hole boring cutter, and it is most
The peak of high point and cutter 3 apart from h3 be 0.3mm, can be during deep hole machining, while bore hole, that is, drill
Method as carrying out (processing mode in the past is first to drill, hole drill be over bore hole again) simultaneously with bore hole has been saved the time, again
It can guarantee that the finish of hole wall, and the bore hole simultaneously during punching, moreover it is possible to ensure the precision of bore hole.
