Group of the machine tool that install this world is narrow liability company (factory of Yuan Anyang machine tool) the major that is center lathe of our country Ø630 produces manufacturer, 1/4 what its crop occupies this norms lathe in the whole nation, produce per year a quantity to amount to many 1000. According to the country place of 7 ministries and commissions issues a file to ask, change produce for the CW6163B center lathe that produces now. CW6163B lathe lathe bed is wide (550mm) , main shaft is thick, rigid diameter of via of good, main shaft is big (Ø100mm) , smooth board sudden shift operates with crossed handle, delightful sex is good. But clutch of box of its main shaft is controlled with hydraulic pressure, to whorl and worm treatment, control is not quite convenient, safe. Additionally main shaft box operates centrally, also be inferior to operating dispersedly to maintenance convenient, transmission shaft of main shaft box is decorated in casing in front, also affect a worker to expect up and down greatly. According to the feedback opinion of the user, we feel need develops a kind of new Ø630 center lathe. The guiding ideology that designs new lathe is: Retain the advantage of lathe of CW6163B, C630-1, the part adopts the advanced structure of lathe of DUE630 of German VDF company. Below the premise that assures machine tool function, use mature structure as far as possible, give attention to two or morethings the manufacturing condition of my factory, strive to achieve the outward appearance novel, the structure is reliable, performance is good, operation and maintenance are convenient, cost is low. The CWA6163 lathe of new design uses leg of lathe bed, bed to connect the structure of whole of half be born of body, the tigidity that raised lathe bed and precision maintain a gender, and appearance of lathe bed of lathe of sectional reservation PCW6163B mixes lathe bed the advantage of width respect. Main shaft box uses the transmission fashion line of C630-1 lathe and mode of operation, main shaft instead 3 bearing. Bearing is mixed with 3182 biserial roller bearing before auger horn discharges ball bearing collocation 2268 pairs to use, main shaft precision is stable, tigidity is good. Gearshift is used operate dispersedly. I axis clutch is moved with mechanical hand operate. Mechanical brake, turn off a machine is smooth, be adjusted easily and control, diameter of main shaft via is Ø86mm. Feed box is orgnaization of double axis slippage, operate rotate to be pulled type, as identical as CW6163B. Smooth board box consults the swift current of German DUE630 lathe board box structure, the structure is simple, the part is little, cost low; surmounts clutch to use one-way bearing, safe clutch uses attrition formula, facilitate adjust, control easily. Means of tailstock sleeve locking uses the form of C630-1, locking is reliable. CWA6163 lathe implemented the tentative plan before the design basically, the shell is beautiful, distribution is equitable, have a times to feel. Precision accords with GB4020-97 standard, machine tool trends is characteristic, include negative charge experiment, fight brace up the experiment, noise, oil that prevent leakage all up to mark or design requirement. Machine tool parameter and function index accord with the regulation of country music series basically. Contrast of 3 kinds of lathe sees a table. Wide 490mm of model C630-1CW6163BCWA6163 lathe bed, structure of asymmetry hill shape, bits is discharged inside, leg of lathe bed bed is apart. Wide 550mm, structure of symmetrical hill shape, bits is discharged outside, leg of lathe bed bed is apart. Wide 550mm, structure of symmetrical hill shape, bits is discharged outside, leg of lathe bed bed joins system structure of whole of half be born. Diameter of main shaft via (inner cone of aperture of Mm)Ø70Ø100Ø86 main shaft is metric 80 metric 120 metric rotate speed of 100 main shaft (R/min)14 ～ 750(18 class) 7. Class of 5 ～ 1000(18) 12.
Class of 5 ～ 1000(20) instrument of motive of hand of means of control of clutch of attrition of main shaft box operates hydraulic pressure operates with machinery of C630-1 brake means hydraulic pressure is the same as structure of bearing of C630-1 main shaft 2 bearing 3 bearing, bearing is before 31822132 use 3 bearing with 2268132 collocation, bearing is before 31822128 with 2268128 collocation box of use main shaft operates dispersive concentration lubricates with C630-1 splatter oil pump lubricates compulsively to be with configuration of shafting of transmission shaft of box of CW6163B main shaft behind casing of main shaft box centrally do not affect a worker to expect up and down. In casing of main shaft box in front, affect a worker to expect up and down. Does with 0630-1 feed box collect connect orgnaization: ?
