1 minute / ) . Its do line fundamental is: Implementation is full automatic change, improve manufacturing efficiency effectively, avoid to be operated by accident artificially; It is core in order to enhance market competition ability, achieve rate of expensive go into operation, and run cost is low. In addition, all fronts of this product line uses water-solubility cutting liquid. 2, full automatic this product line machines product line of crankshaft finish machining basically object workpiece is crankshaft of 4 crocks of gasoline engine, production program is 150000 / year (C/T: 1.
2 minutes / ) . This entire line principle is in held to full automatic on the base that crankshaft product line makes line principle, return the correspondence that can realize workpiece breed automatically to change. In addition, beat to assure crankshaft finished product of precision exceedingly good, make its smooth, quiet in the movement in engine, this product line was used machine connecting rod neck first, the craft of main shaft neck is machined after. The main facility in this product line is numerical control CBN stage of double emery wheel is followed move grinder GF50M-70T, its are main the characteristic includes: (1) circumgyrate of synchro control workpiece (C axis) with feed of emery wheel stage (X axis) along with the connecting rod neck that moves grinding crankshaft. Agree with different and phyletic crankshaft (abduct ministry journey and phasic point of view are different) in all line production, saved change model measure. (2) stage of numerical control double emery wheel is controlled independently severally, can undertake each journal grinding independently, in order to improve manufacturing efficiency. (3) use TOYODA grinder is consistent [TOYODA STAT] is static pressure grinding spindle bearing and static press slideway technology; Drive of emery wheel stage uses technology of advanced linear electric machinery. (4) grinding uses the water-solubility cooling fluid that can reclaim, with use refrigeration oily means photograph is compared, big political integrity restricted finished cost. Graph product line of treatment of camshaft of working procedure of grinding of neck of 2 crankshaft main shaft, connecting rod neck is full automatic the treatment object workpiece of product line of camshaft finish machining is gasoline engine camshaft, production program is 300 thousand / year (C/T: 1 minute / ) . Its do line fundamental is: Implementation is full automatic change, completely rate of expensive go into operation, flexible reach grinding of CBN high speed, all fronts uses water-solubility cutting liquid. The main device that its product line uses is numerical control GC32M-63 of grinder of camshaft of emery wheel of CBN of linear electric machinery and GL5P-63III of grinder of neck of grinding spindle of CBN of double top drive. Among them, numerical control is linear the characteristic of GC32M-63 of grinder of camshaft of emery wheel of electric machinery CBN is: (1) the treatment efficiency that has the world to precede. Linear velocity of emery wheel surface can amount to 200m/s, fast feed speed is φ 60m/min. 8 cam workpiece machines the Leng Jizhu iron that mental allowance is 6mm to need 52s only, it is the cam grinder with the at present rapiddest rate of the treatment on the world. (2) workpiece circumgyrate (C axis) control for infinitely variable speeds, the biggest grinding is finished to measure in making sure cam turns in a week, grinding obstruction is more balanced, the treatment precision of outline molded lines rises, because this shortened effectively,machine metre, realize grinding of high speed, high accuracy thereby. (3) static the feed of stage of light qualitative emery wheel with the tall mobile sensitivity that controls drive of slideway feed, linear electric machinery is tectonic, can come true without unoccupied place feed of idling, very close to each other. Answer of latest technology quickly while servo and system of feed of emery wheel stage are reducing cam grinding time, raised cam to machine the quality of the face. (4) TOYODA GC50 open mode controls a system to wait for all sorts of self-correcting functions to be configured as the standard, increase change model supportive function, locomotive operation is handy and reliable, realized high accuracy treatment easily. (5) can pass installation double an emery wheel, undertake inphase horn cam while grinding, improve treatment efficiency further; What also can use means of grinding of single emery wheel to enhance a machine tool is flexible. Graph 3 numerical control are linear the characteristic with the mainest GL5P-63III of grinder of neck of grinding spindle of CBN of drive of double tip of GC32M-63 of grinder of camshaft of emery wheel of electric machinery CBN is Gao Rou sex and high accuracy. It used means of distinctive double top and synchronous drive, the double tip that relies on a machine tool adopts roll of camshaft of attrition force drive, undertake grinding is machined. The tip adopts servo synchronism drive, top sleeve is OK numerical control is mobile, the workpiece that realized different length mixes line treatment. In addition, the machine tool deserves to have active quantity appearance, each journal to grinding can undertake be metricaled actively, realize accurate treatment. The motor product line that JTEKT company abounds 60 years by right of its makes experience, had had the equipment delivery outstanding achievement of 30000 above, because this makes equipment of world top class engine,create a company. In Chinese market, JTEKT company is depending on powerful technical actual strength, the professional, after service team that respects property, the move since the development that is Chinese automobile industry urges action actively. Believe JTEKT company depends on his " the dream that pursues a technology, the technology that brings you to have value " this one concept, innovation of broad user of meeting and home goes better future.
