Lower Cost: The manufacturing process for a rolled screw is much more efficient than that of a ground screw, resulting in lower costs and higher value for the right applications.
Faster Delivery: Standard ballnuts and screw shafts are stock items. Delivery is FAST.
Lead Accuracy: Accu Tech USA rolled ballscrews are rolled by using precision CNC rolling machines. Lead accuracies of 0.018 mm/300 mm available.
Standard Characteristics (all configurations)
- Ballscrew and ballnut are surface hardened to a specific hardness and case depth to maintain high rigidity and durability.
- Multiple thread starts are available for higher rigidity and durability.
- Ball circulation tubes offer smooth ball circulation inside the ballnut.
- Accurate ball circle diameters (BCD) through length of ballscrew provides consistent drag torque and low noise
- Gothic Arch thread profile increases rigidity and accuracy
External Ball Circulation
- Lowest noise due to longer ball circulation paths
- Smoothest operation
- Best solution for long lead or large diameter ballscrews
Internal Ball Circulation
- Compact ballnut designs provide an outer diameter smaller than that of an equivalent external ball circulation nut. Suitable for machines with limited installation space.
High Lead: High rigidity, low noise and thermal control.
- 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.
- High-speed Ballscrews provide traverse speeds greater than 100 m/min for performance cutting machine tools
