Product Description

Product Description

PERFORMANCE
- Suitable for various machining fields such as automobile mold, aerospace, printing, packaging, textile,  industry, etc.     
 - The floor area of the bridge- type gantry structure is about 56% of the traditional machine which is with table moving. .   - Fixed table with double load capacity, and the machining characteristics of the machine tool are not affected by the quality of the workpiece.    
 - The X-axis of the cross beam is designed with a double column and center of gravity drive structure to improve the stability of machining. .  
- X, Y axes adopt heavy-duty linear rolling guide way, Z axis square ram box guideway structure. .  
- The cross beam adopts the combination of vertical orthogonal linear guide and box guide way .  
- X-axis synchronous dual drive with full closed-loop control to improve accuracy and reliability. .  
- Three-axis with independent lubrication oil recovery system. .  
- Balancing cylinders are arranged symmetrically on both sides of the ram, and the Z- axis has a fast response speed.      
- The spindle adopts WEIDA two-speed gear box with high output torque.
