Screw rotor machining machine
- Screw compressor dedicated processing machine
- Equipped with full-axis scale feedback, enabling high-precision machining.
- It inherits the traditional angled sliding structure and offers exceptional damping performance.
- High-torque spindle enables one-pass machining with a dedicated profile cutter.

Full axis scale feedback is standard equipment.
Scale feedback is standard on each of the X/Z/A/C axes, enabling stable and high-precision machining.
Angular sliding structure with excellent damping properties
By adopting a square slide structure, it achieves excellent machining performance and stability even in screw rotor machining under high load conditions.
High Torque Main Shaft
The high-torque spindle enables single-pass machining even in screw rotor machining, which involves high cutting resistance, contributing to improved productivity.
