• High Machining Efficiency: Compared with conventional turning processes, productivity is increased by 8-25 times. Rough and semi-finish milling can be completed in a single setup, with grinding allowance precisely controlled within 0.05–0.15mm, significantly reducing subsequent grinding time.
• Excellent Precision Adaptability: Dedicated form cutters combined with multi-axis synchronous control enable accurate machining of multi-start and variable-lead raceways. Raceway cross-section accuracy and lead precision are far superior to those achieved by standard machining equipment.
• Wide Material Compatibility: Designed for high-hardness materials, the machine is capable of machining materials with hardness exceeding HRC60.
• High Structural Rigidity: A large-span rectangular box-way structure provides high rigidity and high machining accuracy.
• Strong Process Flexibility: By changing the cutter head and adjusting CNC parameters, planetary roller screws with different diameters, leads, and numbers of starts can be processed without complex fixture replacement.
