Fully Automatic Precision Machine Tool CK6180
The use of hard rail CNC lathes is suitable for heavy cutting, large molds and high hardness workpieces. And adopt independent spindle: strong adaptability, high processing precision, high efficiency, reduce labor intensity, stable speed, widely used. The hard rail CNC lathe refers to the casting part that the guide rail and the bed are one, and then the guide rail is processed on the basis of the casting. That is, the shape of the guide rail is cast on the bed, and then the guide rail is processed after quenching and grinding, and the bed and the guide rail are not necessarily integrated, for example, the steel guide rail is nailed to the bed after processing. The sliding contact surface of the hard rail is large, the rigidity is good, the seismic ability is strong, the bearing capacity is strong, and it is suitable for heavy load cutting.
5. The main shaft of the spindle box is a through shaft structure, using high-precision adjustable radial clearance double row short cylindrical roller bearings. Through optimized design, a larger main shaft diameter and optimal support span are adopted to improve the rotational accuracy and dynamic and static stiffness of the main shaft. The top of the spindle adopts a flange type short cone handle structure, which improves the connection stiffness between the top and the spindle.
6. The tool holder adopts trapezoidal screw or ball screw horizontally, and high-precision rack and double toothed bar clearance structure longitudinally, which improves the transmission accuracy of the tool holder.
