As a result of a lot of congenital advantages of shrinkage fitting collet, it already became a mould to machine the collet of cutting tool of high accuracy mainstream of market first selection. Mould industry is far to machining the requirement of precision outclass is common treatment. Accordingly, how to choose appropriate cutting tool collet according to its characteristic and advantage, it is the main task that height must cause to pay close attention to in mould treatment. In going 10 years, shrinkage fitting collet already was accepted generally in industry of North America mould, its application is increasingly wide, help mould job shops retain competition ability of its whole world thereby. As a whole, the most mould manufactory of North America area often ignores the cutting tool clip that milling machines to hold an issue. However, mould industry is actually to raising cutting tool clip holds precision to ask in production market the most pressing fractionize industry. As a result of a lot of congenital advantages of shrinkage fitting collet, it already became a mould to machine the collet of cutting tool of high accuracy mainstream of market first selection. Should machine an industry to turning into increasingly as North America mould to the challenge global competition market, the requirement of cost of costly to reducing labor already became the urgent matter of die manufacturer. The target of most mould job shops is the handiwork that decrease or cancels a mould completely abrade act the role of handling time with essence of life. This one target can come true through a variety of means, include to use electric spark to engrave steel of modular machine, strong to temper by dipping in water pattern to undertake hard milling, and begin level to undertake cutting of close clean figuration from treatment. To answer these challenges, mould job shops is forced to examine their whole treatment technological process afresh. For example, be treatment to choose correct machine tool already was the issue that needs a consideration exclusively no longer, to realize efficient treatment, collet of package of software of research and system of affirmatory and appropriate machine tool control, CAD/CAM, cutting tool and cutting cutting tool are crucial. When solution of cutting tool collet is seeking solution of cutting tool collet for the treatment of any types, must pay close attention to 3 of cutting tool collet main character above all: Rigid: Tigidity depends on sufficient awl surface contact and cutting tool collet the correct clamp on machine tool main shaft. Precision: Precision depends on of blade of cutting tool cutting most trail jumps. Evenly: Depend on evenly pair of cutting tool collet (include all accessory, if pull a hammer) the balance after with cutting tool combination is assembled. But, because mould treatment industry is right the requirement of precision is far outclass is common treatment, because this must is opposite,choose appropriate cutting tool collet to give more takes seriously. For example, mould job shops must consider the following issue normally: The geometrical appearance of cutting tool collet: Cutting tool collet should avoid to interfere collision with workpiece happening. Machine to discharge (EDM) , must undertake to electrode high accuracy, efficient treatment. In workpiece treatment, often need to face deep costal region board treatment challenge. In addition, treatment is deep model antrum (be like large door heart board or bumper mould) when, collet of requirement cutting tool can be thorough model antrum interior space undertakes machining. The cleanness of cutting tool collet spends: Jump to avoid to introduce additional means error, the cleanness that must maintain cutting tool collet (the) when machining black lead electrode especially. Cutting tool life: Because high-end cutting tool needs to be in,optimal cutting property is acquired inside short handling time as far as possible, these cutting tool used advanced coating normally, the price is quite high also, because this asks,these cutting tool have longer working life. Bright and clean degree: Use higher cutting rate, older feed rate and lesser cutting deepness, the treatment appearance with can be obtained better is bright and clean degree. Come to reduce the vibration of blade of cutting tool cutting the smallest, the balance of cutting tool collet is crucial. In addition, the good performance that discharge bits also is helpful for improving the appearance bright and clean degree. Considering afore-mentioned additional requirements, a lot of mould job shops discover, because have certain and congenital advantage, shrinkage fitting collet is become likely complete the optimal selection with treatment highly competitive task correctly. In addition, it is easier that inductive type adds the development of machine of shrinkage fitting knife to also make the process that hold a knife becomes, quicker and safer; In the meantime, the investment cost that uses this kind of advanced technique also is reduced increasingly. The advantage of shrinkage fitting collet is machined to the mould, shrinkage fitting collet has the following 10 congenital advantages: The shrinkage fitting collet that the high accuracy that surmounts hard makes correctly is in the 3 times the oldest way that should assure 3 μ M at place of cutting tool diameter jumps error. When different personnel undertakes operating, this precision also has extremely tall repeatability. The collet of dainty appearance shrinkage fitting with good applicability uses cone angle to be the inclined wall form of 3 ° , the appearance is very fine and cabinet. Collide to prevent collet and workpiece interference, if be necessary, also can build collet body of instead straight wall. Collet of shrinkage fitting of huge clamp torque is around arbor periphery undertakes 360 ° clamp to cutting tool, its clamp torque is accordingly great, displacement can happen in order to prevent cutting tool when rough machining or finish machining, drop work substantially thereby discard as useless rate. Can choose lengthen lever to divide collet of standard shrinkage fitting beyond, the user still can choose the lever of shrinkage fitting lengthen of different specifications. Machining deep model when antrum, in can loading lever of shrinkage fitting lengthen collet of standard shrinkage fitting, obtain diameter to jump thereby the collet of error minimum is outspread length. Balance repeatability and adjustable evenly do not have athletic component as a result of shrinkage fitting collet, because this can be offerred,exceed the optimal balance repeatability of any tool collet systems on the market. Below a lot of circumstances, if job shops buys to deserve to have appropriate attachment (if pull a hammer) , the shrinkage fitting collet that passes good balance, and use itself do not have inherent lopsided sex element (like plane) high grade cutting tool, so they need not be adjusted reentry travel is additionally evenly subtly normally, exceedingly good balance property can be acquired in high speed cutting. Of course, after undertaking assembly to collet system (collet + cutting tool + pull hammer or) of cooling fluid canal, if return need to undertake to collet system on balancing machine additional balance is operated, so a lot of shrinkage fitting collet that city makes work distribute stock already inside on park collet, what use easily is adjustable evenly. Shorten the time that change a knife / an efficient induction is used to increase chance of shrinkage fitting knife in if changing knife course,reducing collet accessory inventory, so the time changing a knife of shrinkage fitting collet is the shortest in all sorts of tool collet, need 10 seconds of 5 ~ to be able to be finished only change a knife, more important is, can maintain the consistency of the time that change a knife from beginning to end. The shrinkage fitting collet that this assembles with respect to machine of use outfit knife can win more cutting time, and need not make machine tool idling waits to change a knife. In addition, the workshop needs reserve scarcely spare collet accessory (the claw that be like clip, pressure cap, sealed dish wait for) , can simplify thereby flow. Collet cleanness is spent look high from design principle, shrinkage fitting collet is a typical sealed system. Accordingly, the impurity of the generation when treatment (like black lead dust, cut bits to wait) the possibility that enters collet hole is dinky. If foreign matter enters collet Kong Zhong, often can affect its diameter to jump precision. Suit inside collet of cooling means shrinkage fitting uses innovation normally means general cooling fluid or cold air / oily mist is carried go up to blade of cutting tool cutting, conduce to purify cutting bits thereby, the treatment appearance with be helpful for obtaining better is bright and clean degree. In addition, if mould job shops needs to undertake high accuracy is gotten,cut treatment, because shrinkage fitting collet does not need accessory or special clip claw, because this is clip,hold inside the ideal collet of cooling broach, the sealed design of collet is complete but refrigerative fluid arranges flow to move in cutting tool interior. The each outfit knife of the collet of consistency shrinkage fitting that holds a knife has admirable consistency between the operation, the mould job shops that this runs to high speed is particularly advantageous. For example, the operation holding a knife that by different operation personnel has on shrinkage fitting collet has same state, won't get all sorts of variable (if place claw pressing,the cap is tightened too or too loose, collet did not fill minute of cleanness to wait) influence. In addition, the place before be like is narrated, the balance repeatability of shrinkage fitting collet is extremely tall also. This kind of consistency that hold a knife and balance repeatability are united in wedlock, make life of well and truly monitoring cutting tool mixes job shops calculate the workpiece amount that holds a knife to be able to be machined every time, this is all in all also to improving the treatment efficiency of the workshop. The convenience sex that offers money is current, the manufacturer of cutting tool collet with main much can offer the whole world shrinkage fitting collet (as standard product) . Accordingly, mould job shops won't be placed like bedspring of use high accuracy head or a few otherer collet system appears in that way the problem that offer money (these collet have only sometimes or very few a few manufacturer produce) . The vendor that chooses collet of shrinkage fitting of shrinkage fitting collet correctly is very much, product quality also the good and bad are intermingled. Accordingly, when asking to choose collet according to specific treatment, have relevant research crucial. Generally speaking, the cutting tool collet that buys at first will prolong the service life that machines a machine tool. Consider to discover, the total cost of cutting tool collet is equal to (or be less than) machine tool life period inside 0 what machine process total cost.

5% . The relation of aperture of cutting tool collet and cone decided its clip holds precision. The product that selects real him production specializations with what produce cutting tool collet only the company is very main, the collet of high accuracy cutting tool that can make sure the treatment that is you offers quality to agree so. The material of shrinkage fitting collet also is a when choose collet correctly main factor. If make the data that collet place uses do not accord with a requirement, because its heat - cooling loop number is limited, may shorten the service life of shrinkage fitting collet. The shrinkage fitting collet that uses right stuff to make should keep termless (long-term) service life. In addition, the front dimension of shrinkage fitting collet must accord with German DIN standard, the different and cooling means that just can use the machine that hold a knife so, this are very important. Generally speaking, recommend buy have a variety of inside buy " functional option " shrinkage fitting collet (for example, the lopsided quantity of the collet after the course is balanced is less than 1gmm, can design evenly, form " DIN B " the) such as cooling fluid transmission option. Such, when the scope of application of collet will expand further henceforth, limitation is lesser. Finally, the company of collet of production shrinkage fitting should be this industry " leading sheep " , in the research that can support new cutting tool mix continually concept infuse product and development, widen shrinkage fitting collet processes the application of the industry in the mould further thereby. For example, haimer company develops a kind to have recently fight brace up shrinkage fitting collet of the function, this collet has wonderful installation tigidity, conduce to when rough machining restrain vibration, improve treatment thereby the surface is bright and clean degree. The boss of a lot of job shops and manager express brief summary, shrinkage fitting collet is a when they make in going 5 years optimal investment. Technology of cutting tool shrinkage fitting is accepted extensively in mould treatment industry and apply, produced crucial effect to strengthening the engineering capability of North America and implementation to grow continuously.
