CNC Lathe Machine

Product Model: CK6140/750/1000/1500/2000

1. Main structural features of the machine

1. This machine tool is a CNC machine tool with high speed, high precision and high reliabilitythe machine base, machine body, machine head box and other main components are all cast with high-strength materials to ensure the long-term stability of the machine tool.

2. Adopting the structure of the flat machine body, the machine tool has high positional accuracy, smooth chip removal, suitable for high-speed and high-precision machining.

3. High-speed, high-precision, high-rigidity independent spindle, servo spindle motor, can achieve higher spindle speed. The spindle is assembled in a constant temperature room. After assembling, it runs at constant temperature for 72 hours, and then runs for 72 hours after being put on the machine to ensure the reliability of high-speed and high-precision performance.

4. Use electric mode the tool change speed is fast, and the positioning accuracy is high.

5. X, Z direction is to adopt a C3 level double nut preloading load of precision ball screw, servo motor with high torque and low inertia import elastic coupling screw straight league, screw pre-stretching structure is used in bearing can eliminate drive back gap and thermal deformation precompensation machine running for a long time influence on accuracy, ensure the position precision and repeat positioning accuracy; Advanced centralized automatic lubrication device, timing, quantitative automatic intermittent lubrication, stable and reliable .

6. Machine protection adopts full protection design, beautiful and unique, waterproof and anti-debris, safe and reliable, convenient maintenance.
