【正文】 s own precision precision is it mean following odd to adjust. （ 1） The side base of the lathe , installation level of the post base . （ 2） The side base of the lathe , distortion of post base , lathe guide. （ 3） The radial of the axis of the main shaft hole beats . （ 4） Parallel degree to the lathe guide of axis of the main shaft hole. （ 5） The bush hole axis of the jig or the parallel degree to the guide of kinds of hole axis.. （ 6） Main shaft, and jig bush hole or kinds of pieces of hole to guide distance degree. （ 7） Turn the gyration centre of the workingbench and coaxial degree of the machining center of the main shaft case round. 5 Take a trial run When the state knob switch of the work piece is put adjusting the position , operate every button such as clamping , relaxing , advancing , going backwards etc., can carry on single step movements of the lathe , this function is used in adjustment of the test run of the lathe or the cutter ,etc. mainly. When the switch is put in the automatic state , movements of the lathe are totally controlled automatically by the procedure , load and unload after the work piece each time, is it press clamp , lift button to need only, lathe can automatic circulation , work that go round and begin again go down, until press and stop the button, function this use for to to process automatically part mainly. Through is it operate everything to be normal to take a trial run , is it is it is it is it prove to cut to try on to process to go on to the part, measure through Ministry of MachineBuilding Industry 17 idea test center, dimensional tolerance and precision accord with specification requirement , part of drawing. 6 This association lathe characteristic (1)Part in mon use and standard part on the lathe account for more than 70% of the total amount of spare part of the lathe , so the cycle designed and making is short, economy is profitable. (2)The bed adopts specialpurpose jig , cutter and bores the template , after disposable adjustment, processing its quality is it guarantee by craft , the engineering level to the attenbant is expected much to equip all, and labour intensity is low. (3)This equipment is small in floor space, the machining accuracy is high, it is reliable that performance is steady, it is a dedicated device that the automobile factory processed the hub . (4)Lathe is it get into , expand , cut with scissors and load and unload 4 pieces of Engineer location to have, load and unload and process going on in step, so the production efficiency of the lathe is high, can process more than 15 parts per hour, processing quality is steady. (5)The lathe adopts the programmable control procedure to control, therefore the automatic degree is high, and can work out the procedure online in case of not changing electric circuit in movement of the lathe , change at random 。 The automatic way is controlled and realized automatic circulation according to processing the flow chart by the procedure . Cooling system The lathe outside has specialpurpose case of cooling with foot wheel, it is easy to maintain and clear up , the electrical machinery of coolant pump is 0. 12KW. Capacity 50L/min, cooling water is it get into template divide three No. into , 10 lead the water outlet all the way while being every to reach, correspondent to 10 cutters, Russia realizes the cooling of the cutter effectively. Coolant pump is it start automatically to control by procedure when the slippery worker in Taiwan enters, implement to process into cooling of work piece, it is closed automatically until terminal point that the worker enters. 4 The installation which makes the lathe up is debugged and the precision is examined Running through constant debugging to the part of the system all the time in the course of assembling, and to influencing one39。s location . It turn workingbench round it last folk prescription to gyration sport,equivalent to pieces of production line not automatic not round, its structure is pact, the realization that production efficiency is high , can be convenient is automaticallied control electrically. Lathe this whether tooth record is it turn workingbench round to make a reservation, it it makes up to be as follows, mainly Flower disc , job body of the platform , many tooth make a reservation record , collect bits trough , respirator , card urgent cylinder , piston , transfer location gear wheel to, transfer location clutch , hydraulic pressure valve to Tooth one which turns the workingbench round is a terminal surface gear wheel that the couple distributing in the circumference clenched the teeth each other, Is it make a reservation to clench the teeth by many tooth by circumference, is it orient precision to be high with rigidity kind characteristic to have, No matter radial strength, axial force or tangential force, can play the function of feeling relieved automatically so on the revolving stage. Jig The jig enables being used for preventing and fixing and is processed the part. It is an important condition of guaranteeing the machining accuracy to choose to process correctly with the datum of orienting. Size precision of jig install level of precision influence machining accuracy of part directly, This lathe has four sets of jigs the same in size in all, Deploy it in turning the workingbench round and with going back to the revolving stage centre to form the assembly line of concentric circles . The jig
