Skill of work of efficient small Kong Jia

001 inches (of humanness hair diameter 1/3) small small-sized hole. This kind can machine the process capability that has the metallic spare parts that amounts to thousands of small hole, much professional work was won in textile and industry of medical apparatus and instruments for the company, because have rarely,other company can have such process capability. And, entrust already had prior operation by other contractor to the most spare parts of National Jet company. Then National Jet company becomes to add the professional cutting company that gets small hole on semi-manufactured goods spare parts. And this advocates with this company this starts work all along it seems that the guiding principle of treatment has conflict. In usually they grind hard metal by manual blade small small-sized bit. The machine tool of small small-sized bore that oneself are made before use itself company and sells is machined. At the same time they still machine EDM electrode mould, in order to cooperates various distinctive inside aperture appearance. This was according with this company to decide hard to come true overall the big target that the product machines, and not only confine Yu Kongjia is versed in. National Jet company is in the CNC treatment facilities that already introduced, the Swiss lathe that included to equipment has air main shaft and the vertical machining center that cool through the aperture inside main shaft, in order to improve the process capability of general machining and small small-sized hole. This company still is attracting a large number of users besides special skill of small small-sized bore besides, still execute the advantage of one-time treatment through conduct propaganda: With treatment of the rapiddest rate, consign product, reduce a spare parts to machine working procedure and reduce manufacturing cost to wait win whole spare parts to process business. Chuck Condor of selling manager of National Jet company and general manager James Odom have this company tiny Kong Jia is versed in and how from market information is obtained over there the user, and the concerned information that raises manufacturing efficiency and economic benefits further. The data of the following introduction basically is offerred by them. The company of National Jet of skill of work of small Kong Jia of ceaseless development was built by the trailblazer John Cupler of miniature bore technology 1937. Old before, what manufacturer of broach of a foreign country produces him most miniature broach sends Cupler, ask whether he can produce a so little bit. And the way that Mr Cupler answers them is to was in this to a hole was drilled on broach and send it. These miniature alveolus are in only just can see times higher below microscope, the payoff of a lot of small small-sized bore also is similar to standard measure auger cut treatment. When undertaking assessment to a new job every time, national Jet company must decide most effective opening machines a method above all. This still gets a basis to machine spare parts sort greatly, inside precision of appearance of aperture diameter, geometry, dimension asks and the lot size of spare parts of deepness, treatment, and the treatment method that uses so. The tiny Kong Jia that accuses a machine tool to often be used at scientific research to project, small lot is produced or need few number only of the hand of microscope is versed in. A few manufacturer that devote oneself to tiny Kong Jia to be versed in the machine tool is developed, be being offerred mostly is the hand charges type machine tool, method of this one treatment wants the 30 time of the century on restrospect to. Of other although had used CNC workbench to try to transform, but still maintaining the feed that controls bit with handiwork, the hand moves feed such tiny diameter broach, the worker that needs adroitness has manual feeling. A lot of small alveolus that National Jet company has summed up get cut experience. "Our skilled worker handlers in fact can by ' feeling ' affirm whether small small-sized bit already was ground blunt. " Mr Condor says. Graph the technical special skill or knowledge that treatment of 1 small hole became National Jet company. Graphic representation is 0.

The hair of the person of 003 inches of diameters, by 0.

001 inches little bit gets the graphic representation that break-through crosses. Peck the machine program that get to be in be used in operation of each miniature drilling almost, in order to assure successful platoon bits, assure the quality of small hole, exterior surface roughness and maximize broach service life. Cooling fluid or light qualitative oily in order to cool and from get a needle to eliminate to cut bits. Introduce according to Mr Condor, the great majority that National Jet company produces is compressed model the long way that little bit place has is compared (L/D) for 7:1, and 10:1Be considered as what still can assure to offer close together common difference normally the largest percentage. One small alveolus is gotten on a curved surface, need gets aperture of one tiny blind to undertake directing beforehand on the spare parts, with preventing opening bend or " deflective " . The oriented and little bit that has be gettinged beforehand needs to be designed very shortly commonly, had the oldest long way is compared (L/D) for 2: 1. The company has a kind of patent treatment method, small small-sized and oriented hole can be machined on very sharp workpiece edge. Be machined to tall productivity or need the part of treatment to having a lot of small alveolus, national Jet company will use their CNC machining center or lathe. Hand motive bed often is used job pay before new CNC machine tool, undertake trying getting to the workpiece of treatment. Basically be to decide to need to change in the process that machining so small the frequency that gets cutting tool. This company is new purchased 2215 VMC by company of Fadal Machining Center (the Hatsworth of California city) production, via main shaft Kong Zhu enters cooling fluid, can get be less than 2.

The alveolus of 5 Mm. This kind machines means, cancelled to peck get a means, because cut bits,can eliminate smoothly from cutting area through cooling fluid. Although less diametical bit does not have cooling fluid passageway, also can use on this one machine tool. The locates condition can use a convention point feet of the spare parts or the linearity instrument that design technically undertake check and undertaking locating debugging to the spare parts. L32 Switzerland lathe by Marubeni Citizen-Cincom company (the Allendale of new jersey) production, can provide the complete treatment of cylinder spare parts, in including to hold clip in, execute tiny Kong Zuan to cut. This lathe has the pneumatic main shaft of 30000r/min of two highest turn up, little bit machines drive. Pneumatic main shaft is used by more ground actually undertake nicety machines small diameter bore is not to exceed high speed to machine. This lathe returns equipment to have feed of a good stuff implement, offer longer nobody change a spare parts to machine. Graph the 2 Swiss lathe that use main shaft of pneumatic of an outfit stock undertake operation of general turning, milling and tiny Kong Zuan cut. Mr Condor admits a lot of people to be quite to tiny Kong Neng below relatively inferior speed be finished to surprised by treatment, "We are to the diameter 0.

005 inches small Xiaokong, the choice issued treatment to score huge success in the main shaft rotate speed of 500 ～ 3000r/min, " Mr Condor says, "In feed very little state of affairs falls, the main shaft rotate speed that was not necessary to use thousands of rotation per minute will machine small hole. " the purify orifice wool after drilling small hole perverses, also be a when complete good aperture treatment main factor. Every time bore has the burr that needs cleared aperture exit. National Jet company uses surface of the aperture inside polishing and the handiwork outside using disclose of one little bit to give orifice burr to come to go normally burr method. National Jet company to hard the burr of purify, for example the steel wire that small diameter tells oily aperture and the alveolus that are not a circle to apply small diameter or undertake purify through EDM equipment. "But machine to small deep hole, we do not use EDM commonly, because electrode is easy,the ministry is mixed by burn alveolus generation taper. " Mr Odom says. Graph 3 miniature EDM uses at managing material or other the circumstance that goes burr and bore compare difficulty or cannot be being machined. The EDM machine tool of National Jet company can be machined small to 0.

The small Xiaokong of 001 inches of diameters. Besides undertake tiny Kong Jia is versed in, the EDM machine tool of miniature still can keep clear of to already broke off from inside the spare parts the little bit inside alveolus. The diameter of broach is very tiny, breaking off consequently is understandable. The EDM machine tool of a few companies has deploy linear electric machinery, the workbench that is used at X and Y axis moves quickly. Still provided system of tray clamping apparatus at the same time, offer the spare parts outside machine to fast outfit is placed and change. EDM machine tool often is mixed all night undertaking nobody turn operation on the weekend. Newest EDM machine tool has a machine tool that is based on PC to control a system, make offer the CAM assembler that uses on CNC machining center so, change the treatment on EDM machine tool quickly. Of small hole detect National Jet company is not every tiny Kong Dou that goes up to every spare parts undertake detecting, it is to adopt Nikon vision system actually small to every hole undertakes detecting. The dimension precision of can small to nicety hole and surface roughness have this vision system detect, will detect the result delivers an user through E-mail. But to a few go up the part that the design has tiny opening, there is small Xiaokong in spinneret for example, using Nikon vision system cannot detect, for this, the company designed to be able to detect accurately the new method of alveolus geometry appearance. To check small hole geometry appearance is mixed the appearance outline of small hole, national Jet company is divided into the oak puddle of two parts to the infuse in aperture, after balata mud shapes, meeting by take out from Kong Zhong, the concerned information such as small hole outline and geometrical appearance can measure microscope to fall to watch balata pattern and get through be in. Graph the spinneret spare parts of 4 classics prior operation, can offer very quick spare parts delivery to pursue the 5 puddle that use oak examine appearance of geometry of complex and small hole. Previously the geometrical appearance precision to small hole cannot be checked. The ability of very strong small small-sized bore that machines place of National Jet company to have in holding clip already helped a company walk out of the trough of recent manufacturing industry depression. However, the company thinks it must expand this one ability limits arrives the industrial domain of other, in order to create a better business chance. "Our tiny Kong Zuan cuts capacity the industrial domain outside already beginning an end scores a success, for example radio news report and aviation and spaceflight industry, it can support us to finish a lot of other R&D project. " Mr Condor says. "Our key still is the treatment market of the small small-sized part that growing ceaselessly. " recent economic depression also is in sturdily afresh the determination that after machining the market into alveolus of in a subtle way, continues to advance. Our tiny Kong Jia is versed in, often be the final treatment of whole spare parts. Perhaps arrange the immediateness in the spare parts to machine working procedure finally. " Mr Odom says. National Jet company made many effort recently, to the user conduct propaganda is in in outfit clip, finish whole spare parts to machine (also weigh one-time treatment) advantage. Purchase new CNC machining center, its the plan pays Zhu Yusheng to produce actual. This is opposite to already had the manufacturer of position in manufacturing industry, had crossed before professional bounds is moved toward further flexible change, always be helpful. It is the economy that the one-time treatment that summary of National Jet company gives will give an user to bring and manufacturing benefit below: ◆ makes a product rapid consign. Be in by a company in outfit clip, complete treatment of whole spare parts, mean need to be carried rarely and be carried only, handling time concentration, make process a product can quick delivery. The first part that National Jet company uses one-time treatment means is thread machining and the diameter that have a key are car of a need 0.

The minor volume carburettor of 005 inches of via. The company is to be after the labor situation that has all wanting that machine first, drill small hole on the spare parts finally. National Jet company proved for the user, it used the in part of original handling time only, with respect to can good in the treatment on Swiss lathe whole part, win this production job finally for the company. ◆ gets used to change of new products plan quickly, this are very important also. Get used to change of new products plan quickly, national Jet company is its main textile user, inventory the semifinished product of the spare parts such as many spinneret. Because carpet manufacturer cannot await the time of a month for new spinning jet. The company was adopted leave makings and rough machining semifinished product beforehand, once receive order, the other geometry feature that can add small hole and spare parts place quickly to need on semifinished product. ◆ one-time treatment brings tall treatment precision, decreased for many times to install the mounting error that clip causes greatly, assured the treatment precision of the spare parts steadily. Avoided to be not satisfied because of the spare parts before specify specification and meet with of the user censure. Additional, the user workshop that those undertake integral part is produced won't consider those are in 2 form process possibly serious problem, for instance small the deepness that get. ◆ special experience. National Jet company in its tiny Kong Zuan cuts a field, accumulated a lot of valuable experience, it suggests, pass those who design a structure to transform sometimes, can make treatment becomes easy and make produce cost to drop. "The small Xiaokong that if one user needs to get a very inaccessible design on the spare parts,asks, the proposal designs blueprint by large hole taper transfers the structural appearance of small hole, will make treatment becomes easy and can not affect product performance. " Mr Condor says. It is admittedly important that a company has a fixed professional place in manufacturing industry. But professional very strong workshop can discover very quickly, according to the market need of the user, research develops new technology new technology, agile ground provides a variety of technology services for the user, have the development to the enterprise very main effect. These more than 1 kinds of technologies serve continuity development, will promote an enterprise the competition ability in the market greatly. CNC Milling
