Yang Yongxiu (the first car of Chinese machining center of foreword of 130000) of Changchun of Jilin of place of trial-produce of total courtyard of group company research and development is the numerical control machine tool that contains knife library, can come true to change a knife automatically, automation rate is higher. VMC850L vertical machining center, or so journey is X to, around journey is Y to, fluctuation journey is Z to. Main treatment dish kind with the axis kind component, in dish kind with the axis kind hole is made all round component kind, keyway, all sorts of model the treatment of the face. VRNC210 is deployed on the machine tool four-axle revolving stage, assemble four-axle circumgyrate type machining center, if pursue 1. The purpose is to come true to install clip to be able to machine much place to take angle place, also can realize treatment of 4 axes linkage at the same time, treatment is sophisticated model face, improve treatment quality and treatment efficiency. The geometrical precision of the machine tool is the foundation that machines precision, only the geometrical precision of the machine tool achieves demand ability to assure to machine precision. In producing treatment actually, because get the influence of all sorts of elements, if be operated by accident, the influence that machines vibration to wait, can make the precision of machine tool oneself produces change. Machining center is processing form of this four-axle circumgyrate when accurate component, unqualified circumstance appears, detect through 3 coordinate, the niche that discovers workpiece spends deviation bigger, through the analysis, the precision problem that is four-axle revolving stage brings about workpiece out of tolerance. Graph machining center of 1 four-axle circumgyrate one, four-axle precision adjusts an operation to contain stick of standard of a circle above all, material is 45# steel, the course moves qualitative processing, prevent to happen be out of shape. 20mm of standard marvellous diameter, length 200mm, coaxial is spent be less than 0.

02mm. The scale of the diameter because of standard club and length is 1: 10, length is longer also, the workpiece length of common treatment is in 200mm less than, the precision requirement of workpiece is in commonly 0.

02mm less than, if use standard club to do the precision when adjusting to assure,be so inside this limits, the product that treatment comes out also won't have a problem. (One) four-axle revolving stage and Xiang Ping of machine tool X spend the 3 ungual chuck that adjust a revolving stage to go up to clear clean all right, standard club installs clip to be inside the 3 ungual chuck of revolving stage. Load dial gauge magnetic force watch to sit, express magnetic force fixed go up in machine tool main shaft. The watch needle of dial gauge is pressed in the standard to go up marvellously bus, handwheel of jolty machine tool, make its express a needle to move along the axes direction of standard club, see dial gauge whether have fluctuant. If change,be less than 0.

02mm, silent thinks revolving stage and way of standard of machine tool mesa are consistent. If change,be more than 0.

02mm, in a way shakes revolving stage to secure bolt, in feet of padding of lower part of revolving stage base, the big rootlet of feet of a place of strategic importance occupies the numeric adjustment that what dial gauge mirrors, relapse next jolty handwheel and replace rule of a place of strategic importance, tone is in to dial gauge 0.

02mm less than, also achieved the demand with revolving stage and consistent way of standard of machine tool mesa. The watch needle of dial gauge is pressed in the side generatrix of standard club, handwheel of jolty machine tool, make its express a needle to move along the axes direction of standard club, see dial gauge whether have fluctuant. If change,be less than 0.

02mm, acquiesce goes for revolving stage and Xiang Ping of machine tool X. If change,be more than 0.

02mm, in a way shakes revolving stage to secure bolt, with base of revolving stage of cupreous marvellous knock, relapse jolty handwheel and knock base, tone is in to dial gauge 0.

02mm less than, the side generatrix that also achieved standard club and the requirement that Xiang Ping of machine tool X goes, secure the locking bolt of improving stage base next. (2) four-axle revolving stage places dish of coaxial to spend with 3 claw adjust be in assured above below the premise that narrates Xiang Ping of four-axle revolving stage and machine tool X to spend a requirement all right, the four-axle revolving stage that has as follows again places dish of coaxial to spend with 3 claw adjust. Press needle of dial gauge watch on the generatrix of standard good side that is far from revolving stage a side, handwheel of jolty machine tool, rotational 4 axes revolving stage, if change,be less than 0.

02mm, show four-axle revolving stage and 3 claw clip dish coaxial spends demand of OK and contented normal treatment. If change,be more than 0.

02mm, in a way shakes the fixed bolt of 3 ungual chuck, use cupreous hammer knock next 3 ungual chuck, relapse jolty handwheel and knock 3 ungual chuck, those who be moved to dial gauge is fluctuant in 0.

02mm less than, also achieved four-axle revolving stage and the requirement that 3 claw place dish of coaxial to spend. (3) four-axle revolving stage and tailstock coaxial are spent adjust adjust in what assure to undertake four-axle revolving stage and top tailstock coaxial are spent below four-axle revolving stage and the premise that 3 claw place dish of coaxial to spend. Dial gauge presses what standing by club of standard of tailstock one aspect of the matter to go up bus, move next top tailstock, make top top is inside the central aperture of standard club, what observe dial gauge right now is fluctuant. If change,be less than 0.

01mm, the center that shows tailstock tip and center of four-axle revolving stage are coaxial. If change,be more than 0.

01mm, the center that shows tailstock tip follows revolving stage center high tall abhorrent. In be more than 0.

01mm when, two kinds of circumstances appear. One kind is tailstock under revolving stage center, adjusting a method is the foot of a place of strategic importance that pays certain height in tailstock lower part, the condition that measurement of feet of a place of strategic importance reflects according to dial gauge is decided, till be moved to tailstock center and revolving stage center,wait tall. The 2nd kind of circumstance is center of revolving stage of tailstock prep above, adjust a method to be differred according to height namely, undertake repairing wearing tailstock bottom, tone reachs tailstock center and revolving stage center to wait tall. Dial gauge is pressed in the side generatrix that stands by club of standard of tailstock one aspect of the matter, move next top tailstock, make top top is inside the central aperture of standard club, what observe dial gauge right now is fluctuant. If change,be less than 0.

01mm, the center of acquiescent tailstock tip and center of four-axle revolving stage are coaxial. If change,be more than 0.

01mm, the center that shows tailstock tip is spent with coaxial of revolving stage center bad. Two kinds of circumstances appear, one kind is the side outside tailstock deflection, additionally one kind is deflection inside. Above the adjustment of two kinds of circumstances the method is bottom of tailstock of knock of the hammer that use copper, those who be moved to dial gauge is fluctuant be less than 0.

01mm, also assured tailstock center and coaxial of center of four-axle revolving stage. . 2, the last word adopts pair of four-axle circumgyrate form the precision of the four-axle revolving stage of machining center is adjusted, solved accurate component to machine occurrence position to spend bad problem. Other the machine tool of this model, adjust a method according to ours, can achieve corresponding precision likewise, have certain promotion sense. CNC Milling CNC Machining
