Use at the boring cutter of essence of air cylinder aperture of machining center

Half essence boring comes true on machining center, boring of essence of life machines the precision requirement for aperture of contented air cylinder apart, valenite used the process that boring of half essence boring, essence of life machines apart on cutting tool design, in order to avoid the vibration that at the same time treatment produces. Half essence boring and end face pour horn to use push boring (main shaft be issued to lower levels) means, boring of essence of life is used pull boring (main shaft goes up) means. When treatment, take a knife to undertake changing a knife automatically directly from knife library by the manipulator that change a knife above all, next main shaft locates treatment position, undertake half essence boring above all (3 cutting tool are machined at the same time) , right now the knife clip of boring of essence of life maintains in original position, namely the radius with located needle of boring cutter of essence of life is less than the radius with located point of a knife of razor blade of half essence boring, do not participate in cutting (see a picture 2) . After the semifinishing machining that finish, main shaft continues to be versed in, undertake end face pours wine cup, after completing part, main shaft is regressive 1 ～ 2mm. At this moment, 0.
4 ～ 0.
6MPa (or greater pressure) compress air to enter gas mouth to input boring lever interior through be located in lateral of knife handle flange from machine tool main shaft, by the compression of the input air urges the drag link inside boring lever; Pull rod promotes form of cake of a wedge, carry clip of penknife of boring of essence of life on the head to the dimension of finish machining, next regressive labour enters main shaft, undertake boring of essence of life; After boring of the essence that finish, the compression inside boring lever air by eduction, right now pull rod loses pressure, make by orgnaization of in-house a bedspring clip of penknife of boring of essence of life returns original position, finish whole treatment to circulate (see a picture 3) ; Next main shaft locates afresh again, machine circularly the rest of air cylinder aperture. Graph aperture of air cylinder of boring of 2 half essence (push boring) graph aperture of air cylinder of 3 essence boring (pull boring) 2.
After all aperture that realize automatic compensation to should machine a cylinder body on machining center, provide pair of aperture that already machined to undertake metrical through online check, if discover dimension decrescent (main as a result of bit wear away cause) , criterion the dimension that boring cutter of essence of life places needs shift of essence of life. Before machining next cylinder body, main shaft can carry cutting tool to installation to be on the pneumatic chuck device on clamping apparatus, see a picture 4. Through this pneumatic chuck fixed position intensifies cutting tool after the essence of foremost end moves knob, circumgyrate of machine tool main shaft, main shaft arranges hour hand or anticlockwise every circumgyrate 10 ° , dimension of boring of essence of life is added on radius direction or decrease 0.
0025mm, realize the automatic compensation of finish machining dimension thereby. Most can circumgyrate 360 ° , just adjust an amount always up in the diameter for 0.
18mm. Graph device of 4 pneumatic chuck 3.
The design of this kind of unprecedented that tall treatment precision and control of dependability Valenite pneumatic compensate boring cutter of air cylinder aperture automatically can be obtained on machining center with same on special machine tool treatment function and stability. Because boring cutter used compensation of revolving of machining center main shaft to replace the servo electric machinery on private plane to compensate a system, can make sure boring of essence of life repeats fixed position precision to be in 0.
002mm, the cylinder of air cylinder aperture spends tolerancepublic errand to be less than 0.
This pneumatic controls other characteristic to compensate boring cutter of air cylinder aperture automatically besides the 3 big characteristics besides above, still have the following characteristic; (1) inside the belt cold; (2) dynamic balancing design, use PCBN razor blade to undertake high speed is machined; (3) 0 what can use workshop mark to match directly.
4 ～ 0.
The compression of 6MPa air, do not need to add other pressure boost equipment, the high-pressured cooling fluid that also can use 5MPa comes clip of drive essence boring cutter; (4) adjust precision tall, the smallest adjust a quantity to be radius direction 0.
0025mm; (5) half essence boring, parameter of cutting of boring of essence of life can be adjusted alone; (6) boring of essence of life uses the treatment that pull boring, avoid to decline knife mark; (7) treatment efficiency is tall; (8) maintenance cost is low. CNC Milling
