Abstract

A kind of processing method of deep via, fixture and knife bar are fixed, 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 was 10 20mm/ hours.While knife bar works, water under high pressure is passed through, water under high pressure flows between workpiece and cutter, is reserved from water-cooling groove, carries out circulating cooling to cutter and workpiece, while go out metal fragment.The present invention is simple in construction, suitable for processing deep via, can provide operating efficiency significantly, through practical operation, process same hole, than the time that traditional diamond-making technique can save more than half；And cooled down in process, caused metal fragment greatly reduces, and processing the metal bar to get off can also recycle.

Description

A kind of processing method of deep via

Technical field

The present invention relates to a kind of processing method in hole, especially a kind of processing method of deep via.

Background technology

Current hole forming method, cut using boring machine or drilling machine mostly, substantial amounts of metal fragment can be produced, 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.

The content of the invention

For above-mentioned the deficiencies in the prior art, the invention provides a kind of simple in construction, high efficiency, mastering for material is saved Hole forming method.

To achieve the above object, the technical solution adopted by the present invention is：A kind of processing method of deep via, first from length The deep via to be processed of ratio long and hollow knife bar and fixture are spent, fixture and knife bar are fixed, multiple cutters are uniformly fixed on The surrounding of fixture, on fixture, the rear side of cutter processing water-cooling groove, the distance between the top of cutter and fixture outer shroud are 10mm-12mm, 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 start to process deep via, the rotating speed of knife bar is 130-150 revs/min, and feed speed is 10-20mm/ hours.Worked in knife bar While, water under high pressure is passed through, water under high pressure flows between workpiece and cutter, is reserved from water-cooling groove, cutter and workpiece are followed Ring cools down, while goes out metal fragment；After drilling through, the metal bar in workpiece is taken out, completes the processing of deep via.

Preferably, described knife bar is provided with antivibration pump.

Preferably, described fixture is provided with hole boring cutter, and its peak is higher 0.2-0.4mm than the peak of cutter.

Preferably, described hole boring cutter material is high-speed tool steel.

The present invention is simple in construction, suitable for processing deep via, can provide operating efficiency 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, caused metal Chip greatly reduces, and processing the metal bar to get off can also recycle.Using the method deep hole processing, compared to existing Drill bit, reduce the contact area in boring procedure, substantially increase the efficiency of drilling, and because blade stability is good, lead to The hole that the method drills out is crossed, hole wall is round and smooth, and finish can reach more than 6.3, blank core can completely be extracted into one Bar, the hole of the diameter of bar only than needing to process is small 20-30mm, 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 describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made Embodiment, belong to the scope of protection of the invention.

As Figure 1-Figure 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 and knife bar 1 are fixed, both total lengths be 6.3 meters.Four cutters 3 are uniformly fixed on folder The surrounding of tool 2, on fixture 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 is 10mm, and the distance between the bottom of cutter 3 and the inner ring of fixture 2 h2 are 12mm, and this distance is guaranteeing to obtain maximum While metal bar 7, water cooling can be sufficiently carried out, and process easily；High-pressure water pipe is connected in the rear end of knife bar 1 5, then start to process deep via, the rotating speed of knife bar 1 is 130 revs/min, and feed speed is 15mm/ hours.Worked in knife bar 1 Meanwhile water under high pressure is passed through, water under high pressure is flowed between knife bar 1 and metal bar 7, is reserved from water-cooling groove 8, and cutter 3 and workpiece 6 are entered Row circulating cooling, while go out metal fragment；After drilling through, the metal bar 7 in workpiece 6 is taken out, completes the processing of deep via. Described knife bar 1 is provided with antivibration pump 4.The height of antivibration pump 4 is slightly below the peak for pressing from both sides cutter 3, because hole depth is larger, is boring During if knife bar 1 anti-life is rocked, can cause the position that cutter 3 bores that deviation occurs, it is sufficiently oily to may result in hole wall, Antivibration pump 4 can set multiple according to the depth of drilling.Fixture 2 is provided with hole boring cutter, its peak and the peak of cutter 3 away from It is 0.3mm from h3, can be during deep hole machining, while bore hole, that is, drilling and bore hole carry out (adding in the past simultaneously Work mode is first to drill, and hole drill is over bore hole again) as method saved the time, and can ensures the finish of hole wall, and During punching simultaneously bore hole, moreover it is possible to ensure the precision of bore hole.
