Features of CNC gantry milling machine body castings

Time:2020-02-11 18:14 Click counts:
 
1. CNC machine tool bed, column, beam, sliding saddle, and headstock are made of high-quality HT250 resin sand, high-strength cast iron, which has been tempered twice, and reasonable reinforcement structure. The machine has good rigidity and stability. High precision and high efficiency.
 
2. The machine tool adopts a gantry fixed beam frame structure, which has good rigidity and accuracy retention.
 
3. Spindle configuration, the centerline of the spindle is close to the Z-axis guide rail, which greatly reduces the bending deformation due to the influence of thermal deformation and cutting torque to ensure accuracy.
 
4. The Z-axis feed design adopts dual-cylinder counterweights to balance the position close to the center of gravity of the movement. The configuration of the driving screw and the center of the spindle motor eliminates the occurrence of unbalanced moments. The sliding saddle is equipped with adjustable gap pressure plates, which is conducive to improving positioning accuracy.
 
5. The spindle adopts oil-cooled circulating cooling to ensure the high precision of the spindle.
 
6. It adopts timing and quantitative automatic lubricating device, which has low wear and is suitable for long-term operation requirements.
