The poles of ball screw adopt the NSK high-precision angle of contact ball screw bearingMaking Molds VMC1890 Vertical CNC Machinng Tools 1.6Tons Load Capacity Quick details: 1. Use 3D-CAD and finite element analysis to delevlop high-rigidity machine tool structure.2. Resin bonded sand molding,twice aging,and special tank-type structure and optimized rib-reinforced lay-out,make the machine tool of good rigidity and hysteresis loss. 3. X.Y.Z three axles all adopt precise linear rolling guide rail(THK or HIWI).4. Less noise,low resistance,high speed,high precision.5. Three axles all adopt C3 degree high precision ball screw,fix the poles of ball screw,fix the poles of ball screw and pre-pull,and optimize drive rigidity,reduce the heat distortion. 6. The poles of ball screw adopt the NSK high-precision angle of contact ball screw bearing. Product features: 1. High-speed/high precision spindleHigh rigidity,high precision,big hole diameter spindle design,adopyt the precise slide angle ball bearing support.High rotary spindle provides high-speed cutting for customers,ensure the long-term stabilization of machine tool's precision.The spindle adopts synchronous belt drive of big torsion,no friction and less noise. 2. Fast-speed/reliable tool-change systemCan choose 20 bamboo split type or 24 arm press type ATC device,and can rotate the blade cutter very fast,steadily and reliably. 3. Machine tool cooling systemThe machine tool prepares three passes cooling liquid and one pass cooling air nozzle to make cutter cool.The design of economical and reliable spindle head cooling system(optional),avoid the problem of place error caused by the spindle head temperature raising,ensure the spindle head's working precision,extend the spindle's service life. 4. Humanized operation systemDouble-open wide protection door for operator to access working table more conveniently Specification Of Vertical machine center VMC1890
