1,The main castings are cast by advanced cast iron by resin sand process. Using advanced finite element analysis technology for optimization design, advanced structure, reasonable layout, and after the secondary aging treatment, can ensure the long-term and stable processing stability of the machine tool, the appearance design is beautiful and humanized;
2,Integrated integral base, bed body thick, large guide rail span. Dual-drive guide rail, stable structure and strong rigidity, good precision maintenance;
3, large torque spindle, with a strong spindle servo motor, smooth operation, high accuracy, durable.
4, the machine tool spindle bearing using precision NSK Angle contact ball bearing, can get high precision, high carrying capacity, high speed optimization combination,
5, the bidirectional pre-stretching process, greatly reduce the bias torque, improve the force of the wire bar, is conducive to improve the machining accuracy of the machine tool.
6.The front of the Z-direction guide rail adopts stainless steel protective cover to protect the guide rail and prolong its service life.
7. the two shaft screw are using high precision ball screw, with scientific and advanced assembly technology, small thermal deformation, high transmission precision.
8, screw support using well-known brands of precision bearings, screw lock nut with high precision lock nut, improve the screw support and locking accuracy, further improve the processing accuracy of the machine tool;
9, the use of automatic centralized lubrication system, through the set oil injection time interval and oil injection time to lubricate the wire bar, guide rail and other moving parts, to ensure the normal use of the accuracy and service life of the machine tool;
