A、High rigidity, long precision retention
The machine tool bed, saddle, table, column, spindle box and other large pieces are molded of high quality resin sand、cast by High-quality cast iron、and adopted box or honeycomb structure and arranged with sufficient ribs, and aging , So that the machine can be high rigidity and long-term stability of accuracy.
X-axis, Y-axis are large cast iron hardened precision grinding guide, sliding surface viscous plastic, static and dynamic friction coefficient is similar to reduce the machine crawl low speed, high positioning accuracy,while achieving high dynamic response characteristics, combined into an impeccable high rigidity, high stability of the mechanical guidance system.
Imported from Taiwan's high-performance spindle, with grease lubrication, spindle bearings can obtain a constant and reliable lubrication, environmentally friendly, and maintenance-free performance.
Three-direction feeding unit adopts Taiwan Shangyin (HIWIN) or Yintai (PMI) products C3 precision double-nut ball screw, which exert preload at both ends to eliminate the thermal elongation caused by the loss of accuracy.
B、High accuracy, high dynamic response characteristics
Spindle with Taiwan's products, which placed in the spindle box,Imported Japan (or Germany) precision angular contact spindle bearings,the span of support is large, so that the spindle to obtain high rigidity at the same time, access to high spindle accuracy.
Z-axis are large cast iron hardened precision grinding guide, sliding surface viscous plastic, static and dynamic friction coefficient is similar to reduce the machine crawl low speed, high positioning accuracy,
C. thermal stability
Main motor is located in the center of the spindle box, symmetrical force, symmetry of thermal deformation, good thermal stability.
Spindle with constant temperature oil cooling system: In order to improve the machining accuracy, the outer sleeve of the spindle adopts the external cooling pump to carry out the automatic circulating oil cooling
