Dispatch of net of machine tool of Chinese numerical control: Boring machine basically is opposite with boring cutter workpiece already the machine tool that some prefab aperture have boring. Normally, boring cutter rotates give priority to motion, the shift of boring cutter or workpiece moves for feed. It basically is used at processing high accuracy aperture or the precision work that fixed position completes many aperture, still can be engaged in the treatment of the other treatment face that concerns with aperture finish machining in addition. With coaxial of casing spare parts aperture fastens the long aperture boring that is a delegate, it is one of the most serious content in metallic cutting treatment. Although still have now use rear column of boring machine of mill of boring model, guide-post bushing, table to bearing grows boring lever or search artificially the method such as 180 ° carries out workpiece circumgyrate the example of long aperture boring, but some closer year come, use in great quantities as a result of boring machine of numerical control mill and machining center on one hand, make the coordinate of boring machine of mill of of all kinds horizontal locates precision and precision of workbench circumgyrate graduation had bigger rise, long aperture boring gradually by efficient workbench circumgyrate 180 ° bore hole from the tune of fixed position on the other hand of layout of form lathe bed common or of boring machine of mill of table of numerical control dig mass-produced with application, make from machine tool structure workbench circumgyrate 180 ° bore hole from the tune of fixed position, become the only method that grows aperture in the boring on this kinds of machine tool almost. The coaxial that pillar sends tune to bore hole spends an error to reach its to compensate tune of influence mill boring machine to bore hole the main factor that coaxial spends and table mill boring machine are same, also be the graduation error Da of 180 ° tune mixes workbench circumgyrate to make before tune already axes of D1 of half when boring becomes long aperture, after tune again the D2 of aperture of other in part of with coincide of boring axis axes boring long aperture, what need workbench horizontal stroke (X) the Dx2 of fixed position error to mobile Lx=2lx. And workbench circumgyrate 180 ° around, the obliquitous error Df that mesa produces inside Xy coordinate plane, the obliquitous error Dy that arises inside Yz plane and in Y the translation error Dy to generation, it is tune of boring machine of dig table mill bores hole as much the main influencing factor that coaxial spends. But head of exchange of position of space of boring axis axes bores hole the influence that coaxial spends, send the aperture that finish the boring machine of dig table mill of full-length boring with pillar normally, with what even if move,send with workbench normally mill boring machine has table to differ apparently. If the attention is clean, lubricant,the labour of care and maintenance of boring machine decides with reasonable operation. Safeguard what boring machine introduces below daily: 1, before the job begins, check a machine tool each component orgnaization is in good condition, each handle position is normal; Clean machine tool is departmental, observation lubricates each device, irrigate directly to face of machine tool slideway oil-lubricated. 2, in working process, operate correctly, do not permit work of machine tool excess load, not usable and accurate machine tool undertakes rough machining wait. 3, the job ends, cleaning machine bed is departmental, move the machine tool each power source is shut after the component moves to provide the place.
