Precision Ball Screw—High Lead Series FDWE

High-lead ball screws are essential components for high-speed machine tools in the 21st century. High-speed cutting technology represented a significant breakthrough in machine-tool technology during the 20th century and will continue to flourish in the 21st century. Consequently, the role of high-lead ball screws in high-speed machine tools has become even more critical.

Feature

For high-lead ball screws, high rigidity, low noise, and temperature rise control are extremely important.

PMI adopts the following countermeasures and designs to achieve the following characteristics:

High DN value

Under normal circumstances, the DN value of PMI’s high-lead ball screws can reach up to 130,000. However, in certain special cases—such as when both ends of the screw are fixed—the DN value can climb as high as 140,000. If you have such a requirement, please contact our company.

High speed

PMI’s high-lead ball screws offer a travel rate of 100 meters per minute or higher, meeting the requirements for high-speed cutting.

High rigidity

Both the screw and the nut have undergone surface hardening treatment to achieve a specified hardness and effective depth, ensuring high rigidity and durability. Multiple threads can be provided on the screw, increasing the number of steel balls bearing the load and thereby enhancing both rigidity and durability.

Low noise

The specially designed steel ball return mechanism provides a smooth operating environment for the steel balls and ensures that, even at high speeds, the steel balls won't damage the return tube, thereby guaranteeing the quality of the ball screw.

The average and precise ball circle diameter (BCD) on the thread ensures that the ball screw achieves stable and consistent preload torque and reduces noise levels.
