一、Product function 1.The 21-tool drilling and tapping center has the function of a machining center, and it is more efficient than a machining center. The program control part uses Taiwan Hust CNC control system for secondary development system, which can synchronize tool change with workpiece tool change. Machine-friendly dialogue, easy to operate.
2.It is suitable for large and medium batch parts processing, one-time clamping is completed, high efficiency and good precision
3.850 machining center structure, hat-style tool change mode, with Beijing CTB main servo motor with frequency conversion, Delta servo feed motor.It could improve the surface roughness of the workpiece thread and ensure machining accuracy and efficiency.
4.The power head assembly adopts Taiwan brand, precision grinding, good wear resistance and long service life.
5.The Hust CNC system can set the corresponding feed speed according to the needs. After the equipment is used for a long time, the screw rod is worn out, and the system itself has the function of making up the knife.
6.Each motorized sliding surface adopts a centralized automatic lubrication device to ensure the service life of the machine tool.
7.The movement of the sliding table is driven by a servo motor, and multiple coordinates can be set digitally when moving in place, with high positioning accuracy, small vibration and fast response.
8.During the processing, the processing status of the workpiece is displayed on the touch screen, and there is an alarm function if there is a fault.
9.Fully enclosed protection to ensure personal safety and improve the processing environment.
