Single-nut ball screws are widely used in the following fields because of their compact structure, low cost and ability to meet medium precision and load requirements:
1.Optimized Kinematics: The internal ball circulation system is meticulously designed to eliminate vibration, ensuring ultra-smooth movement even at high rotational speeds.
2.Superior Load Distribution: Featuring a high-load-carrying capacity, the structural geometry of the nut and screw tracks ensures uniform pressure distribution to prevent premature fatigue.
3. Minimal Frictional Torque: Advanced surface finishing significantly reduces the starting torque, allowing for high-sensitivity motion control and lower energy consumption in your motor drive systems.
4.Industrial-Grade Durability: Exceptional dust-proof sealing and high-hardness raceways provide robust protection against debris, maintaining peak precision in harsh manufacturing environments.
The processing of ball screw products includes the following steps:
1. Material selection: Select high-quality metal materials, such as high-quality alloy steel, for the main part of the ball screw.
2. Turning: Use a lathe to turn the metal material. First, fix the metal material on the lathe and use a cutting tool to gradually cut the material into a cylindrical work piece. This step ensures that the ball screw has a precise diameter and length.
3. Screw thread processing: Screw thread processing is performed on the outer surface of the ball screw. This requires the use of a thread tool to cut the thread line onto the ball screw so that it can be matched with other equipment.
4. Steel ball processing: Make steel balls of suitable size for rolling movement between the ball screw and the slider. Steel balls are usually made of metal materials and are precisely sized through processing processes such as grinding.
5. Assembly: Assemble the various components of the ball screw. It mainly includes placing the ball screw into the guide rail and ensuring that the steel ball is correctly assembled into the raceway between the ball screw and the slider.
6. Debugging and quality inspection: After assembly, the ball screw needs to be debugged and quality inspected. This includes checking the rolling smoothness, measuring the accuracy and size of the screw, and verifying the quality and performance of the entire ball screw system.
7. Surface treatment: As needed, the ball screw can be surface treated, such as chrome plating, blackening, etc., to improve its wear resistance and corrosion resistance.
