Main spindle and sub-spindle for efficient complete machining

- Machine bed is made of Meehanite HAT 300, carefully heat-treated, high precision machined and subjected to strict quality controls
- High-quality bearings and linear guides, produced in Japan, feature both accuracy and excellent wear-resistance
- High-performance preloaded ball screws are equipped with precision bearings to ensure sustained, smooth, vibration-free operation
- High-torque servo motors by renowned suppliers ensure excellent feed and rapid feed dynamics on all axes
- Main and sub-spindle, including C-axis allow the production of complex parts in one operating step
- Proven design, low-maintenance, and easy handling
- Powerful central coolant system ensures excellent chip removal and long tool life
- Machining with main spindle and sub-spindle saves setup time, and allows machining of the part’s back side without reclamping the workpiece
- For tool mounting, only collet systems that are readily available in stores are used
- A powerful main spindle motor provides sufficient reserve power for demanding production conditions
- Rapid feeds up to 24000 mm/min, high productivity and production speeds
- Optional rod loader is available; suitable for use with material feed systems from other suppliers
