FEATURES
Optimal Spindle Head Layout
- The spindle center line closes to z-axis slideways, greatly reducing the possibility of thermal displacement and bending deformation due to side cutting torque.
- Driven by a powerful motor, the spindle head is ideal for various complicated machining with ultra-high accuracy.
- Spindle gearbox is designed as rectangular in cross-section and its structure is symmetrical closed. It ensures the spindle gear box symmetrical heat conduction and preventing thermal distortion and minimizing defection.
Two-step Speed Gearbox
- The spindle running is transmitted through a gearbox, providing high/low speed changes.
- The low speed range gives great torque output, making the machine excellent for heavy cutting. The high speed range is ideal for fine cutting with outstanding surface finish effects.
- All gears in the gearbox are carburized and precision ground for quiet running.
Spindle Oil Cooler
- The spindle oil cooler can adjust to appropriate temperature to control the spindle accordingly and properly.
- The cooler provides excellent cooling feature for gears, stabilizes the precision of the spindle, and extends the lifetime of the spindle and gearbox.
Hydraulic & Nitrogen Gas Dual Counter-balancing System
Two chip augers are provided at the left and right side of the base, which deliver chips to the chip conveyor. The chip augers maintain machine cleanli-ness at all times.
- The nitrogen gas counter-balancing system is equipped with an accumulator, and no additional power unit is required.
- Features no noise and no vibration.
- It ensures extra smooth movement of the spindle head for increased machining accuracy.
