The machining center feed shaft, Y, Z coordinate control, the main shaft for servo motor power drive, knife storage capacity of 1624 is optional. Can realize a variety of disc, plate, shell, CAM, mold and other complex parts in a clamping, complete drilling, milling, boring, expanding, reaming, tapping and other processes, three axis hard rail structure, used in various industries of complex parts of the single and batch production. Processing is programmed, shorten the production cycle, so that users get good economic benefits. VMC850 vertical machining center adopts vertical frame layout, the column is fixed on the bed, the spindle box moves up and down along the column (to), the slide seat moves longitudely along the bed (to), the workbench moves laterally along the slide seat (x) structure. Bed, workbench, slide seat, column, spindle box and other large castings are made of resin sand castings, and after two times of aging treatment to eliminate stress, good stability, high strength, to ensure the stability of the long-term use of precision machine tool, provide a guarantee for the stability of the performance of the machine tool. Soldvorks and Ansy optimization design were used to improve the stiffness and stability of the large and the whole machine, which effectively suppressed the deformation and vibration of the machine tool caused by cutting force. 2. The guide rail of x, V and B axis of the dragging system adopts widened rectangular sliding guide rail, which has been subjected to medium frequency fire and precision grinding; Sliding guide rail surface is coated with PTFE composite material and precision scraping, with automatic forced concentrated lubrication, reduce the friction resistance of feed movement, reduce low speed crawling, improve the precision life of machine tool. X, Y, Z three ball screw shaft, adopt Taiwan professional manufacturers of PMI provides C3 level double nut preloaded ballscrew, on both ends of the ball screw bearing imported P level 60 special bearing contact Angle screw, screw bearing adopts pre-stretching structure, greatly reduces the machine running for a long time in the influence of thermal deformation b axis servo motor with automatic brake function , in the case of power failure, it can automatically lock the motor shaft to hold tight, so that it can not rotate, play a role in safety protection. 3. The spindle group adopts Taiwan famous brand high-speed, high precision and high rigidity spindle unit, and all important parts have been strengthened; Adopt world famous brand P class spindle special bearing and adopt KLUBR NBU15 grease lubrication, the whole set of spindles are assembled under constant temperature conditions, after the computer balance correction and running test, makes the whole set of spindles long service life, high reliability, the spindle can achieve stepless speed regulation in its speed range, the spindle is controlled by motor built-in encoder, can realize spindle orientation and rigid tapping function. The main shaft adopts the central blowing structure. After the main shaft is loose, the central high pressure gas is used to clean the inner cone of the main shaft quickly to ensure the precision of the tool clamping. 4 tool library adopts high quality 16 or 24 high-speed automatic tool change library, tool change accurate, short time, high efficiency, after millions of times of operation test, meet the reliability requirements; Optional configuration of bucket or disc type tool library, bucket type tool library with damping structure, can reduce the impact of movement, ensure the service life of the tool library.
