1. The CK84100 CNC roll lathe bed adopts an overall 4+1 guide rail structure, that is, four rectangular guide rails are arranged horizontally on the bed to provide the movement and positioning of the saddle and tailstock respectively, and an auxiliary rail is set on the vertical surface of the front side of the bed The guide rail serves as auxiliary support for the bed saddle. This ensures that the bed saddle and tool holder have better rigidity and can withstand greater cutting torque.
2. The base guide rail of the bed adopts overall ultrasonic quenching, and the matching surface is affixed with imported guide rail soft belts to ensure the micro-wear movement of each feeding component and maintain high precision and stability for a long time. A certain height difference is designed between the saddle guide rail and the tailstock guide rail to ensure that chips and coolant do not invade the saddle guide rail.
3. The bed saddle tool holder adopts the AO-type overall tool holder solution. The tool holder can improve the rigidity of the tool holder and reduce vibration during machine tool turning. By adjusting the position of the tool holder pad, it can adapt to the roll processing of deep groove grooves. The insufficient rigidity of the tool holder caused by reducing the extension of the tool holder causes the tool holder to resonate and affects the cutting performance.
Our company can also choose to configure CNC tool holders according to customer requirements (recommended for angle steel users).
CK84125
1. The lathe spindle box adopts a reinforced double-wall box structure; the spindle adopts a two-point support form, reasonable bearing configuration, and span design, and the spindle has high rigidity and load-bearing capacity. The optimized design of the transmission system adopts high-frequency quenching and grinding 6-level precision gear transmission so that the spindle box has the characteristics of low noise, high transmission precision, and large output torque.
The spindle transmission adopts a stepless speed regulation scheme of hydraulic automatic 2-speed gear shifting + DC speed regulation motor drive, which enables the machine tool spindle to have a wide and highly dynamic speed regulation range of 1~200rpm.
A button station is designed on the back of the spindle box, which can control operations such as forward and reverse rotation of the spindle and emergency stop.
2. The tailstock uses an independent rotating spindle + axial telescopic adjustment of the tailstock sleeve. The tailstock spindle taper hole is 100-1:5. The tailstock body adopts an integral structure, which eliminates the disadvantages of unstable precision, poor load-bearing capacity, and poor reliability caused by the traditional upper and lower split structures.
The tailstock of the machine tool is equipped with a high-performance pressure sensor, which is used for the setting, measurement, and feedback of the tailstock clamping force when the lathe clamps the workpiece. By setting and adjusting the operating pressure sensing controller, the tightening force of the tailstock tip on the workpiece can be automatically controlled and displayed. The loosening and clamping of the tailstock sleeve are automatically realized through the hydraulic control system.
3. A workpiece thermal deformation compensation mechanism is designed in the tailstock sleeve. During the operation of the machine tool, the axial length change of the workpiece is absorbed and compensated by the disc spring in the sleeve.
