Description
The machine series is mainly used for high-speed and high-precision machining of parts in industries such as automotive components, molds, construction machinery, valves, rail transit, energy, agricultural machinery, and coal mining machinery.
Characters
Machine Structure
- Integrated Design: The machine features a gantry-type structure with an integrated column and crossbeam, enhancing overall rigidity.
- Z-Axis Balance System: Utilizes nitrogen pressure to counterbalance the weight of the spindle box and ram, reducing the load on the servo motor. This minimizes vibration and deformation, improving machining accuracy and stability. Additionally, it reduces mechanical wear, extending the machine’s service life.
3-Axis Motion System
- 3-Axis Guideway: Adopts a roller-type linear guide design, providing fast dynamic response and high precision, ensuring smooth operation without creeping.
- Drive System: The servo motor is directly coupled with a high-precision ball screw, combined with a fixed pre-tensioned structure at both ends, achieving high transmission accuracy and stability.
High-Speed Directly Coupled Spindle
- High-Speed Spindle: BT40 direct- coupled spindle with a maximum speed of 12,000 r/min, delivering excellent cutting efficiency and performance.
- Coolant Prevent: The spindle front end features a labyrinth seal structure and an air curtain protection system, effectively preventing coolant from entering the spindle bearings, extending service life.
- Thermal Control: Equipped with a central air-blow function and an automatic circulation cooling system, significantly reducing temperature rise and thermal deformation, ensuring high machining accuracy and stability.
