  • 02

    Each linear axis of the machine tool is controlled by double drive rings, and the X and Y axes are controlled by electric clearance elimination of screw drive motor, which can realize precise motion control.

  • 03

    The application of the optional direct-drive motor further improves the fast operation of the x-axis and y-axis and the efficient and precise stability accuracy. The matched precision grating is used to match the CNC system to achieve the closed-loop function. The overall system performance improves the geometric accuracy.

  • 04

    Z axis adopts lead screw synchronous drive control technology, and gantry Z axis with balance cylinder structure has higher dynamic performance and motion accuracy.

  • 05

    The screw nut of Z-axis is cooled separately to reduce the influence of thermal deformation on the precision of Z-axis.

A. Spindle

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.
