Undertaking Hui Shibiao follows whorl precision work (WST) in exercise, the exercise cycle that turning machines is very short, this wants height with respect to the work flow of requirement workpiece chuck reliable. And use contain ternary claw type to direct the dynamical chuck of device can come true to lubricate compulsively, at the same time this work way has the characteristic of proper motion adjustment. Can say this is a kind of feasible technology solution. One when be located in German Löffingen is engaged in Hui Shibiao following whorl precision work (WST) enterprise, can be used according to machining a purpose to differ and install the chuck that matchs neatly. And when undertaking to machining batch to amount to 10 thousand workpiece WST works, machine exercise cycle to be 25~60s only to the turning of below one workpiece from this one workpiece, treatment cycle is very short, the demand to workpiece chuck is extremely so high. Before processing work, the work that wants fetch to need treatment above all is placed, close chuck, lubricate and close afresh. Inside the cycle that processes work in every, the clamp action of chuck is extremely much. The manufacturer home that this asks to be engaged in WST working seeks a kind of new chuck regulation. Because, in using the fundamental ungual type that contains a tradition to direct the chuck of device is processing work, wear away big, the meeting when the treatment that having big batch work works often repeats occurrence plane the problem of parallelism and circular exercise respect. Machine to the turning of below one workpiece from this one workpiece, exercise cycle is 25~60s only, machine to such abidance must ask the manufacturing operation flow of chuck is absolutely for exercise lubricant effect mixes on the safe side wear away the value improves the process that seeking program of clamp plant technology greatly in, people is certain the setting of the clamp device of German Forkard limited company is regular, namely mandatory moving meeting brings about those who produce flow dependability to rise. Because use QLC chuck multiple shape the lubricant effect of oriented device mixes ungual type wear away the value will be improved considerably, and the dependability of the WST work flow that can realize people place to ask. What using chuck of 4 years of QLC is multiple shape ungual type is oriented after device, what people discovers effect unexpected is good. Use such clamping apparatus device to make of equipment maintain periodic and affirmatory, that is to say, to clean and lubricate but fixed (every 6 months) whole disassembles clamping apparatus device, avoided an enterprise to be not a plan to stop so machine, the failure free operation that ensured WST works, raised production to machine the high utilization rate of equipment thereby. The high utilization rate that effective working hours machines equipment for 80%+x production works to WST and character: It is definition of effective working hours 80%+x namely. In a day of 24h, machining the machine tool equipment of exercise to have 22h is to be in turning to machine condition. There is spare lubricant inside motor-driven chuck, when treatment works lubricant can be provided for chuck in the lubricant box from add setting, implementation is mandatory lubricant. This is meant, journey of Zhang Jin's ungual every treatment exercise all carries engine oil lubricant. As oriented as traditional ungual pattern device is contrary, what grinding shapes all around is multiple shape the action that ungual type directs plant institute rises is to prevent engine oil to lubricant comes out and volatilize quickly. Such, in machining exercise process, lubricant loss amount will be very few, this to batch Dajujia is versed in cycle is having very large dominant position for short WST work. Through using multiple shape ungual type directs device comes true mandatory lubricant, can make of chuck wear away fall lowest (graph 1) . Graph 1 people can weigh ungual type to direct facial cent comes to device and the bearing that increase from this through how control ungual type is oriented inside device wear away Nextpage in addition, multiple shape ungual type directs device is undertaking mandatory when treatment works allow common difference small, go up in workpiece so when, zhang Jin wears away ungually small. Can ensure workpiece is secured absolutely in the position in turning working procedure so, its end panel swings the value also can be controlled it is in micron limits. In the past, people is through be opposite on a raised content the quality of clamping element undertakes detecting, to WST exercise uses such detecting likewise method. Now, the clamp cycle of clamping element is the most important level that measures clamping element quality. That is to say, the applied state of clamping element is having absolutely sex sense to clamping element quality. Automobile manufacturing industry uses way of durative WST work to undertake turning works normally (graph 2) . The treatment operation that clamping element reachs 700000 times in cycle of the clamp in durative WST exercise is not scarce. This that is to say, calculate and must decide the service life of chuck according to the effective clamp periodicity of chuck. Graph after the 2 precision work that use WST work way to have large quantities of amounts were having extensive trial and test, people decides to be in durative WST exercise the QLC chuck with reliable performance characteristics, accord with the requirement of people in order to make treatment makes the dependability of the flexibility of course of study and pull current Cheng. The lathe on the choose product line of 20 EMAG VL3 composition used QLC chuck, this model lathe contains the turning of two perpendicular settings is unit (graph 3) . In addition, this lathe operation goes to the lavatory simply, do not have special skill requirement to operating personnel. The lathe on the choose product line of EMAG VL3 composition used station of graph 3 20 QLC chuck, this model lathe contains the turning of two perpendicular settings is unit CNC Milling
