The feature of  ck680 chinese used heavy duty cnc vertical turning lathe machine

1.Long-term stability,the machine is a single column vertical rail structure, column, base and slide are used high grade gray cast iron resin sand casting process, and by aging treatment; with the rail surface with ultrasonic sound quenching and paste processing; reasonable structural design, Improve the processing and assembly process, to ensure long-term use of the stability of the machine and the accuracy of maintaining.
2.Can be processed for roughing and finishing.Machine spindle with dual base speed high and low speed servo motor drive, low speed high torque, strong heavy cutting, can also be high-speed cutting.
3.Bear a greater cutting force and feed force. Machine spindle with high precision double row cylindrical roller bearings and two-way thrust angular contact ball bearings, double row cylindrical roller bearing configuration. The configuration of the structure of the largest carrying capacity, can withstand greater cutting force and feed force, a higher radial stiffness and axial stiffness, high rotation accuracy.
4.Simple and reliable structure, low failure rate. X, Z-axis servo motor through the flexible coupling directly drive precision ball screw, can minimize the reverse gap, high positioning accuracy. Z-axis lift configuration balance counterweight, simple and reliable structure, low failure rate. X, Z axis using domestic precision ball screw and ball screw bearings, to meet the high rigidity, high precision cutting requirements. The screw support adopts the pre-tensioned structure, which greatly reduces the influence of the thermal deformation on the precision of the machine during long operation.
5.Timing automatic intermittent lubrication; X, Z axis using advanced centralized automatic lubrication device, regular automatic intermittent lubrication, stable and reliable.
6.The tool holder is accurate and efficient. Machine tool holder using electric knife or row knife form, accurate accuracy, high efficiency.
