A kind of method of processing micropore on glass sealing alloy
Technical field
The invention belongs to electronic component processing technique field, relate to a kind of method of processing micropore on glass sealing alloy.
Background technology
Glass sealing alloy, is iron cobalt nickel alloy again, because it has good electric conductivity, so be used widely in the electronics industry.But glass sealing alloy hardness is high, sticky cutter, chip removal performance is bad, often cause cutter not to be durable, easy to break, often kill, the fault such as easily to burn.So on glass sealing alloy during machining hole, seem and be not easy, especially process diameter and be less than φ 0.6mm, just more difficult during the micropore of the degree of depth more than 3mm, for solving the problem, the method mainly controlling step feed at present artificially solves, although this method is simple, but control not in place, production efficiency is low.Therefore the processing method exploring such micropore never stopped so far.
Summary of the invention
The present invention is directed to and on glass sealing alloy, process diameter be less than φ 0.6mm, the degree of depth more than 3mm micropore existing for technical difficulty, the technical barrier of high around glass sealing alloy hardness, sticky cutter, not easily chip removal, provides a kind of method of processing micropore on glass sealing alloy.
The object of the invention is to be achieved by following technical solution.
Glass sealing alloy is processed a method for micropore, realizes drilling processing micropore on glass sealing alloy mainly through following steps:
(1) cutter material is selected: adopt W-Co kind carbide alloy as cutter material;
(2) Choice and process equipment: miniature precision lathe selected by process equipment, and on the feed arrangement of miniature precision lathe, installed cam wheel adjustment mechanism additional, the effect of automatic withdrawal and feed can be realized;
(3) cutting parameter is set: feed speed is that 0.05-0.15mm/ turns, and the speed of mainshaft is 1500-4500 rev/min;
(4) drilling processing micropore: after the cutting parameter as described in step (3) sets, glass sealing alloy carries out capillary processing;
(5) supply cooling fluid: in the drilling processing micropore process as described in step (4), adopt cooling fluid supply establishment to carry in time and supply cooling fluid, on the one hand cooling, can wash out and get rid of iron filings on the other hand.
Cooling fluid in described step (5) adopts high-pressure coolant, and its cooling fluid pressure is 0.2 ~ 0.8Mpa.
In described step (3), feed speed is that 0.1mm/ turns, and the speed of mainshaft is 4000 revs/min.
In described step (5), cooling fluid pressure is 0.5Mpa.
The invention has the beneficial effects as follows:
Compared with prior art, instant invention overcomes cause cutter not to be durable because sticky cutter, not easily chip removal, hardness are high, easy to break, often kill, the fault such as easily to burn, greatly enhance productivity, extend cutting-tool's used life.Present invention process is simple, safe and reliable, easy to implement, successful, extensively can promote the use in machinery, electronics processing industry.

Detailed description of the invention
Technical scheme of the present invention is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figure 1, a kind of method of processing micropore on glass sealing alloy of the present invention, realizes drilling processing micropore on glass sealing alloy mainly through following steps:
(1) cutter material is selected: adopt W-Co kind carbide alloy as cutter material, through multiple contrast process, practical W-Co kind carbide alloy is more durable;
(2) Choice and process equipment: miniature precision lathe CM6125 selected by process equipment, and on the feed arrangement of miniature precision lathe CM6125, installed cam wheel adjustment mechanism additional, the effect of automatic withdrawal and feed can be realized; The degree of depth that this feeding adjusting mechanism can realize each feed gradually increases function, each working depth reaches about 0.15-0.2mm, automatically withdrawing can be carried out, now cooling fluid is under High Pressure, pour in hole, and the iron filings in hole are discharged, so through 15-20 feed repeatedly, withdrawing and cooling, just by the capillary processing of dark about 3mm out.Adopt this device, intermittent advance when making tool feeding, allow cooling fluid enter working environment in time and reduce temperature, the timely dialysis of interrupted cut iron filings simultaneously;
(3) cutting parameter is set: feed speed is that 0.05-0.15mm/ turns, and the speed of mainshaft is 1500-4500 rev/min;
(4) drilling processing micropore: after the cutting parameter as described in step (3) sets, glass sealing alloy carries out capillary processing;
(5) supply cooling fluid: in the drilling processing micropore process as described in step (4), adopt cooling fluid supply establishment to carry in time and supply cooling fluid, on the one hand cooling, can wash out and get rid of iron filings on the other hand.
Cooling fluid in described step (5) adopts high-pressure coolant, and its cooling fluid pressure is 0.2 ~ 0.8Mpa.
In described step (3), feed speed is that 0.1mm/ turns, and the speed of mainshaft is 4000 revs/min.
In described step (5), cooling fluid pressure is 0.5Mpa.
