Table 8-1 Specification for Model HTM-50H CNC horizontal machining center,8.2 Le
2、sson 20 Specification for CNC Vertical Machining Center,Here is a typical instance of main specification of gantry-type CNC vertical machining centers shown as Table 8-2. Table 8-2 Specification for Model HTM-850G gantry-type CNC vertical machining center,8.3 Reading Materials 19 Specification for C
3、NC Turing-milling Machining Center,Here is a typical instance of main specification of CNC turning-milling machining centers shown as Table 8-3. Table 8-3 Specification for Series F CNC turning-milling machining center,8.4 Reading Materials 20 Structure Feature of CNC Turing-milling Machining Center
4、,There are many structure features of CNC turning-milling machining center as below: 1. The main parts like bed, headstock, carriage, saddle, tailstock are all made of cast-iron with high intensity to provide superior stability and vibration dampening characteristics. 2. Slant bed and slide guide-wa
5、y to obtain high rigidity to be suitable for heavy-duty turning, easy for chip conveying, lower thermal distortion, which can improve the machining accuracy.,3. X and Z axis of lathe choose hardened rectangle moving guide-way which makes the lathe have strong stability. It can be used for large rang
6、e maching, both rough machining and finish machining. 4. The moving parts of X/Z axis driven by digital AC servo motor and ball screw. 5. Spindle driven by large power AC motor which can be changed speed continuously. 6. The feedback of location-ring has stationed encoder, and servo system has high
7、rigidity and positioning accuracy.,7. Lubrication device which can lubricate to the ball screw and guide-way periodicly and constantly. So it can prolong the life cycle. 8. Optional compact design tool setter can improve the work efficiency. 9. Full enclosure splash guard is much safer and more convenient with standard automatic cooling system and centralized chip conveyor device.,
