CK6730 Series High Precision
Comb Type CNC Lathe
Product Introduction:
The CK6730 series high precision comb type CNC lathe adopts a flat bed base structure with
flat-mountain type hardened guides. It is equipped with a hydraulic hollow rotary cylinder, draw-back spring collet, and dovetail comb type tool post for convenient tool adjustment and rapid, accurate tool changes. The tool post plate includes an automatic material-pulling device, enabling automated machining through the CNC system. Users can optionally configure a Y-axis side milling servo power head plus comb tool post or Y-axis side milling servo power head plus 8-station hydraulic turret to achieve turning-milling composite machining.
Features:
1.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.
2.High-speed hydraulic rotary cylinder and draw-back collet ensure reliable workpiece clamping.
3.The secondary supporting bearing of X / Z- axis ball screw adopts special angular contact bearing, with small heat deformation and high feeding accuracy.
4.X/Z -axis adopts servo motors directly coupled to ball screws, guaranteeing high precision transmission.
5. X/Z-axis employ hardened guides for high rigidity, low damping, high precision, and smooth operation.
6. High-performance centralized lubrication ensures timely lubrication of bed guides and screws.
7.Side-mounted independent coolant tank and chip box ensures fluent chip disposal and easy chip removal.
8. The machine has compact structure and small footprint.
Applications:
Applicable to industries such as electronics, communications, instruments, medical devices, and high-efficiency precision machining of small parts.
