The assorted device that die workshop uses cutting tool clamp makes the function of small diameter cutting tool is achieved the biggest change. The user of machining center is facing the choice of a lot of cutting tool clamp. All sorts of Qian machine -- include to secure head of screw, card, heat to cover system and hydraulic substantially to be able to do same business, they can be in keep homocentric knife handle of degree of the clamp below the circumstance with hardness. The forging die in Impact Forge job shops machines a process nevertheless, all sorts of machine achieve the degree of these two targets to still differ in different applied domain. In addition, the special corporation that hold card expanded the range that its use further to clamp device. Want to complete a specific work in a specific workshop, the right choice of clamp device also becomes worse and worse. Be located in Indiana, the job shops of the Impact Forge of Columbus is facing the challenge that needs many outfit card. The small-sized cutting tool that this workshop machines has the very long length that hang buy, these jobs include limited cutting tool to be received not only, also include the treatment of horniness material. The plan of cutting tool clamp that this workshop develops is comprised by the clamp device of many collective jobs. A staff guage can use specification antrum to have many not only deep, and return what can show hollow wall to have many from unoccupied place horn small the forging die inside specific working workshop machines a process, its job basically is a few righter the existing mould that has repaired in solder undertakes be machininged afresh. Craft process designing member Doug Lynch explanation says, hardness achieves 50Rc solder the hardness of the mould should be compared taller before. Rough machining and finish machining are OK one Taichun undertakes the random in machining center of two Okuma horizontal. Among them rough machining includes to locating screw installs jacket blocking a stage to block a diameter to be 1in (1in=0.

0254m) upright milling cutter. Under photograph comparing, the difficulty holding card of finish machining appears a few greater, because the small diameter of the mould asks,the diameter of upright milling cutter is less than 0.

030in. In the meantime, when in-house groove mixes treatment workpiece to leave unoccupied place part smally, need plan of a clamp to make these small-sized cutting tool can be close to the surface adequately to undertake machining thereby. Once upon a time, use heat covers clamp device to achieve these goals the workshop. Below the circumstance of not mobile workpiece, heat covers clamping apparatus to use heat bilges and cold the principle that shrink, the clamping apparatus when heating can be stretched greaten, pack calorie of cutting tool, the clamping apparatus when cooling next can contract again. Heat is covered offerred a clamp the means of small-sized cutting tool, the clamping apparatus of this kind of means has very concise appearance normally, OK and homocentric clamp cutting tool. Mr Lynch says, the problem is hot covered clamping force is with expand quantity and systole measure proportionate, and expanding to be measured with systole is concerned with the dimension of aperture. Enough small hole can suit a workshop medium or small the clamp of cutting tool, the clamping force that it produces wants relatively small. The discovery in treatment, use Melin (Cleveland city, ohio city) the small diameter of the company carries milling cutter to may realize more efficient cutting, have exception of a kind of circumstance, if cutting power is too high, heat covers clamping apparatus to be able to unlock small-sized cutting tool. In other words, machining center and cutting tool can complete treatment, but clamping apparatus is restricted element. The workshop develops among them a plan is to come from Schunk (Morrisville city, north Carolian city) of the company " Tribos " system. Of this system use metal turn over bounce to come clamp cutting tool, this and heat cover clamp very similar, different is, it uses mechanical power to open hole. The other part of plan of Impact Forge workshop is to be in hydraulic outfit card the extension that carries a Tribos. Qian is below device. Pull lever make clamping apparatus drill a round hole, this makes cutting tool OK and built-in the equipment holding card that what the picture below longer life shows is Tribos system. The external form of clamping apparatus aperture is very common, but the circle that it can be imagined to become an ideal normally. When clamping apparatus maintains with this kind of means, can embed cutting tool. The force that releases can make clamping apparatus reactive, at the same time homocentric clamp cutting tool. Job shops was in confluence of clamping apparatus technology one case, tribos uses this system to come by hydraulic unit clamp clamp cutting tool, the job shops of Impact Forge can make Melin company diameter is 0.

03in, stiffness is the movement of ball head knife of 50Rc, the state that run is 8500r/min, 20ipm, cutting deepness is 0.

003in. Mr Lynch says, should cover clamp through heat when small-sized cutting tool, the workshop is unwarrantable these parameter. Should mention maintain extension to come when clamp cutting tool, the clamp plant that job shops discovers to the flexibility that holds the post of He You metal produces power -- include heat to cover system and card head -- the photograph of hydraulic clamping apparatus with likewise achievable task Bidouxun became lubricious a lot of. Card of use water press fitting comes the extension of clamp Tribos system wants to come than using system of a collet the effect of clamp is better, former can make the life of cutting tool increases 3 - - 4 times. Hydraulic clamping apparatus is to use hydraulic will convey of force. This clamping apparatus includes reservoir of liquid of a hydraulic press. The person that use arrives through screwing bolt brings to bear on pressure on the liquid, next pressure can distributing in the metal clamp knife handle comes all round bushing. The compression of this flexibility lining is OK clamp cutting tool. In addition, hydraulic press liquid offers oscillatory damp to serve as gain 2 times. Mr Lynch returns this damp the result for the improvement that is cutting tool life. Job shops uses what come from Schunk company likewise " Tendo " hydraulic clamping apparatus. Pass the consideration of pair of other and hydraulic clamping apparatus, mr Lynch says the life of clamping apparatus needs to cause our attention more than the life of cutting tool. When clamping apparatus is disengaged, go up accidentally close bolt can compress lining, bring about attaint clamping apparatus. The design of Tendo just avoided this problem, because carry an alone machine, bolt is mere be gone up to tighten to stop condition to spark beforehand hydraulic. Such, torsion spanner was not necessary, and also can go up when clamping apparatus is disengaged close bolt. CNC Milling
