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

Graph 1

Valenite pneumatic control compensates boring cutter of essence of air cylinder aperture automatically to be able to satisfy the precision that air cylinder aperture machines to ask better, the mainest is to come true to be compensated automatically in the dimension on machining center, in order to achieve the goal of treatment dimension automata. Additional, it is had and the gender leans in the high accuracy like treatment of special machine tool and Gao Ke.

The finish machining of air cylinder aperture is whole engine cylinder body the Chongzhongzhi in treatment is heavy. To assure the dimension precision of air cylinder aperture, form tolerancepublic errand and the Cpk value that get a stability, the uses an entrance generally rigid private plane in the treatment that at present home is enraging cylinder body, cooperate online (from the line) electronic check is provided and system of automatic compensation cutting tool, the automation that implements measure (automatic or semi-automatic feedback) . But, the competition as auto industry is more and more intense, the development of engine and newer rate are accelerated ceaselessly, rigid special machine tool already was not accorded with far flexible the demand of treatment, show more and more air cylinder aperture to machine move to arrive flexible on higher machining center. Here, this stationery body introduced a boring tool of essence of air cylinder aperture that is used at machining center.

The graph is shown 1 times for the is used at machining center pneumatic control of newest development of American Valenite company compensates boring cutter of air cylinder aperture automatically, this boring cutter uses HSK100 interface, have advantage of a lot of treatment.

1.Half essence boring comes true on machining center, boring of essence of life is machined apart

To satisfy the precision requirement of air cylinder aperture, 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.

2.Automatic compensation comes true on machining center

After all aperture that machine a cylinder body, 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 a quantity always to be 0.18mm up in the diameter.

3.Tall treatment precision reachs dependability

The design that Valenite pneumatic controls this kind of unprecedented that compensates 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 0.01mm.

4.Other characteristic

This pneumatic control compensates 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) the compression of the 0.4 ~ 0.6MPa that can use workshop mark to match directly 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.

Zhang Guobao: Machine tool of clench numerical control this masterstroke

A few days ago, national hair changes appoint vice director, the State Council revitalizes northeast to do director Zhang Guobao to develop an informal discussion to point out in industry of numerical control system, must take strong step, capture numerical control machine tool this masterstroke, master technology of core of numerical control system, raise the fundamental equipment level of manufacturing industry of our country equipment.

Zhang Guobao says, future a certain number of inside year, demand of market of machine tool of our country numerical control will continue with year all 10 – the rate of 15 % rises, to 2010, machine tool of homebred numerical control is produced per year will amount to 100 thousand above, sale will exceed 6 billion dollar, market space is vast. But from the industry on the whole, although our country is machine tool big country, but still not be machine tool powerful nation, industry core competition ability is not strong. Among them very main reason depends on numerical control system and lag of functional component development, especially system of numerical control of machine tool of high-grade numerical control and progress of crucial function component are slow, already became the bottleneck that industry of numerical control machine tool grows. Machine tool of homebred numerical control progresses a few this years very big, a lot of products that count an import for a long time in the past achieved the breakthrough of 0. But, the numerical control system of form a complete set of machine tool of our country high-grade numerical control 99 % above is foreign product, although use partial country product, still also be in try out phase, far the level that did not reach client satisfaction.

Zhang Guobao emphasizes, numerical control system is the core component of numerical control machine tool, its technology level not only the performance quality that affects numerical control machine tool directly and market are had rate, to the important key such as light industrial, spin, shipping the treatment of the spare parts also has very important sense.
