CT4080 A/B

1. Host structure:The overall box bed inclined 30 ° sliding saddle arrangement structure is adopted, which has the advantages of large operation space and smooth chip removal. Bed, spindle box, sliding saddle, skateboard and other large parts are made of high-strength cast iron materials, the use of three-dimensional computer software to optimize the design to ensure the strength of the machine and dynamic and static stiffness. Through the perfect multi-sequence aging treatment process control to eliminate the residual stress of the casting, to ensure that the whole machine has sufficient stability and precision retention.

2. Feeding system: X and Z both adopt high-precision pre-load rolling guide rails and ball screws imported from Japan, which have low friction coefficient and good wear resistance, increase the retention of machine tool accuracy, improve the fast moving speed of the tool holder and extend the service life of the machine tool.

3. Spindle system: This machine is the motor through the high-speed belt directly drive the spindle, there is no gear transmission link in the middle, so the transmission is stable and the noise is small. The front bearing of the main shaft adopts double row cylindrical roller bearings and two angular contact ball bearings, which bear radial force and axial force at the same time. The rear bearing adopts double row cylindrical roller bearings to bear radial force. This structure ensures the high rigidity and high speed of the main shaft, and ensures the low temperature rise of the main shaft during high-speed operation, the thermal balance before and after the main shaft, and the small thermal deformation.

4. Knife Tower: Relying on the hydraulic servo turret Ф 200mm large diameter and high-precision tooth disc centering, it has the advantages of high precision, fast rotation speed, few failures and long life.

5. Hydraulic system: Equipped with an independent hydraulic system to ensure reliable clamping of the chuck and accurate rotation of the turret.

6. Lubrication system: The guide rail and ball screw pair are all lubricated with centralized automatic thin oil. Each node is equipped with a quantitative distributor. Oil is injected into each lubricating part regularly and quantitatively to ensure uniform lubrication of each sliding surface, effectively reducing friction resistance and improving movement. Accuracy ensures the service life of the ball screw pair and the guide rail.

7. Cooling system: Equipped with large flow cooling pump and large capacity water tank, fully guarantee the circulating cooling in the cutting process.

8. Machine Tool Protection: The machine adopts full protection of sheet metal and automatic doors in accordance with safety standards, which not only prevents coolant from splashing, but also ensures safe and humane operation. Each guide rail of the machine tool has a protective cover to prevent chips and coolant from entering the inside of the machine tool, so that the guide rail and screw are free from pollution and corrosion.

9. Chip removal system: Independent water tank, automatic chip conveyor on the right. (Option)
