CH6550 Turning-Milling Center
Product Description:
CH6550 turning-milling center adopts integrated slant bed structure with inclined guides. Equipped with a hollow hydraulic rotary cylinder, hollow hydraulic three-jaw chuck, multi-station power servo turret, and hydraulic programmable tailstock, it utilizes a new-generation CNC system with C-axis and milling functions to achieve comprehensive machining of complex parts in one setup.
Features:
1.30°integral slant bed base structure ensures excellent stability and vibration resistance.
2.The spindle bearing use precision angular contact ball bearings in a front-three/rear-two layout, with dynamic balancing correction and run-in testing for low temperature rise, minimal thermal deformation, smooth operation, and stable accuracy.
3.X/Z-axis ball screws adopt pretensioned nut structures and angular contact bearings to enhance rigidity, thermal resistance, and feed accuracy.
4.X/Z -axis adopts servo motors directly coupled to ball screws, guaranteeing high precision transmission.
5.High-load linear ball guideways ensure good rigidity, low damping, high precision, and smooth operation.
6.Tool holder employs a 12-station power servo turret with high precision, good rigidity and rapid tool selection.
7.The C-axis is equipped with a high-resolution encoder for precise positioning accuracy, high reliability, and continuous indexing capability.
8.Hydraulic chuck clamping/release and tailstock movement are controllable via both program commands and foot pedal switches for flexible operation.
9.Centralized automatic oil lubrication with quantitative distributors ensures uniform lubrication of guides and ball screws, reducing friction, improving motion accuracy, and extending component lifespan.
10.Side and rear chip removal options provide flexible configuration for optimal machining efficiency.
Applications:
Applicable to industries such as automotive, electric, mold manufacturing, telecommunications, instrumentation.
