According to the requirements of customers' products, the main shaft can choose gear structure with high rigidity and high rigidity, and electric main shaft with high speed and high precision, which has good comprehensive performance, convenient maintenance, high efficiency and low vibration.
The mechanical spindle with high rigidity is adopted, and the two-speed gearbox can obtain greater cutting torque to meet the requirements of low-speed and high-torque heavy cutting.
The selected power distribution spindle is used to operate smoothly and process parts with high smoothness, and the matching degree between the tool and the system is more stable and reliable.
B. High-speed nut rotation drive technology and direct drive technology
The machine tool can be equipped with 3 sets of ball screw structure, and adopts the company's innovative and optimized screw rotating nut drive structure, which has the characteristics of small inertia, less heat, high drive efficiency and high dynamic response performance.
The machine tool can be equipped with xy with direct drive technology.
C. The machine tool can be equipped with grating synchronization control
The three axes of the machine tool adopt the synchronous drive technology of motor and screw rod. The shaft dynamic response performance is further improved. At the same time, grating synchronous control technology is adopted to achieve high-precision and low-cost control.
D. The machine tool is equipped with direct-drive motor synchronous control technology
When X axis adopts double drive and Y axis adopts single drive, grating ruler must be used for full closed-loop control to greatly improve the measurement sampling speed, measurement accuracy and control vibration interference.
