Description
High-lead Ballscrews are essential elements and parts for high-speed machine tools of next century.
Features
1.High DN Value︰The DN value can be 130,000 in normal case. For some special cases, for example in a fixed ends case, the DN value can be as high as 140,000. Please contact our engineers for this special application.
2.High Speed︰PMI ;s High-speed Ballscrews provide 100 m/min and even higher traverse speed for machine tools for high performance cutting.
3.High Rigidity︰Both the screw and ball nut are surface hardened to a specific hardness and case depth to maintain high rigidity and durability. Multiple thread starts are available to make more steel balls loaded in the ball nut for higher rigidity and durability.
4.Low Noise︰Special design of ball circulation tubes offer smooth ball circulation inside the ball nut. It also makes safe ball fast running into the tubes without damaging the tubes. Accurate ball circle diameter (BCD) through whole threads for consistent drag torque and low noise.
