Use: Ideal CNC equipments specially used for marking, punching & drilling of pates

Technical characteristics: 
The machine-frame is made by C-type plate welding, with good rigidity. The machine lays three die-stations (among them, one is the marking die-station), which can realize automatic switching. Clamping system can adapt to different workpiece, with zero block as datum mark, and workpiece is supported by rolling-ball working table. X & Y axis action should be controlled by servo motor & ball-screw driving, and double-axis CNC system controls the position of punching, so as to make the whole machining process automatically; Operator may input the sizes of workpiece to computer for repeated calling program. 

Advantages: 
Adopt CNC technology & servo motor infeeding, with high efficiency & stable workpiece precision. 
Realize punching, marking and drilling on the one plate. 
Drilling unit can realize rapid falling, slow work-feeding and quick feeding back for improvement of working efficiency. 
Easy programming, may input the diameter of holes, position and quantity of workpiece to computer, and also use the program generated by lofting software, or adopt direct conversion CAD/CAM. 
With self-diagnosis failures function. 
Lighten the working strength of workers.
