CK 8465/P Heavy Duty Precision CNC Roll Lathe

This machine tool is a CNC roll-and-toss integrated lathe.  It is mainly used for heavy-duty turning and surface polishing after hydraulic support live column, medium cylinder, and laser cladding, and also for semi-finishing and finishing of cast iron, steel, and non-ferrous metal rolls.  The machine tool comprises two independent servo feed shafts in the transverse direction.  The polishing device is installed on one side of the longitudinal drag plate and does not interfere with the processing tool rest of the transverse feed car, It is used for turning and polishing respectively.  The longitudinal and transverse (turning and polishing) movement are driven by high-precision ball screws, and the longitudinal and transverse feed movement guide rails of the tool holder and polishing device are adopted by high-rigidity rectangular guide rails, combined with four-station heavy-duty electric tool holder and special polishing spindle, to improve the high rigidity and stability of the machine tool cutting and polishing.  The bearing of the main shaft adopts a double-row radial short cylindrical roller bearing with high precision and adjustable clearance, so the main shaft has strong rigidity, smooth rotation, and high precision.  The tail seat is composed of an upper body and a lower body, and the upper body is equipped with a spindle, a sleeve, and a spindle center adjustment mechanism.  The lower body is equipped with an quick-moving mechanism for the tail seat, the moto,r and the reducer drive the overall movement of the tail seat, and the high-pressure pump station is installed at the back of the tail seat, which is used for the hydraulic automatic locking and loosening after the tail seat is in place, with interlock protection function.  The tail seat sleeve can be moved by motor drive and manual fine-tuning.  The tail seat has the function of top tightening force display, and the workpiece top tightening torque can be visually adjusted according to the requirement of the workpiece top tightening force.  The above high stability and high rigidity structure design ensures the overall comprehensive machining accuracy of the machine tool.  The moving guide pair adopts wear-resistant adhesive plastic treatment and a centralized lubrication system to implement fixed-point quantitative automatic lubrication to ensure the dynamic response of the whole machine.  The longitudinal and transverse feed rails of the machine tool are fully protected by stainless steel, which is conducive to the long-term maintenance of motion accuracy.
