Features & Advantages
The DFU4005 Ball Screw boasts of the following notable features and advantages:
- High Transmission Efficiency: Due to rolling motion between the screw and nut, the product ensures high transmission efficiency. Compared to traditional sliding screws, the driving torque is less than 1/3, making it an energy-efficient choice.
- High Precision: Manufactured using world-class equipment under strictly controlled environmental conditions, the precision of our ball screw is guaranteed.
- High-Speed Feed and Micro Feed Possible: With minimal starting torque, creeping phenomena observed in sliding motion is eliminated, thereby ensuring accurate micro feeds.
- High Axial Rigidity: By applying preload, axial clearance can be reduced to a negative value, thus enhancing rigidity.
- Reversible Transmission: Ball screws can’t self-lock, ensuring reversible transmission.
Ball Screw Composition and Classification
A ball screw consists of a screw, nut, steel ball, preload piece, reverser, and dustproof device. The types of ball screws include:
- Self-Lubricating Ball Screws: Reduces oil change and waste oil processing costs due to its removable oil removal device.
- Silent Ball Screws: A special groove-type ball spacer suppresses collision noise between balls, allowing smooth and silent operation.
- High-Speed Ball Screws: Characterized by high acceleration, rigidity, high-speed feeding, low vibration, and low noise, they are used in fast feeding of machine tools, high-speed cutting centers, etc.
- Heavy Load Ball Screws: Can withstand large axial loads and are suitable for all-electric design machines, air compressors, semiconductor manufacturing devices, forging manufacturing devices, etc.
Parameters:
The specifications for ball screws can be defined by the following parameters:
- Nominal Diameter: The outer diameter of the screw. Common specifications include 12, 14, 16, 20, 25, 32, 40, 50, 63, 80, 100, 120mm.
- Lead: This is the distance that the nut moves in a straight line when the screw rotates one round. The lead affects the speed of nut movement and the linear thrust that the ball screw can provide.
- Length: This comprises the overall length and the threaded length, which includes the effective stroke and the total thread length.
- Nut Type: Nut type affects installation size and performance. It’s better to choose a standard form to avoid lead-time issues during maintenance.
- Accuracy: The accuracy level of a ball screw plays a vital role in the precision of operations. The DFU4005 Double Nut Grinding Heavy Duty Ball Screw offers high precision levels, meeting a wide range of application requirements.
In summary, the DFU4005 3.175mm Double Nut Grinding Heavy Duty Ball Screw is designed to meet the highest standards of quality and performance. Regardless of your industry or application, we are confident that our product will offer unparalleled performance and longevity. Don’t forget, at ZLV, we offer customization options to fit your unique needs.
