low price Precision Ball Screw

[dfgjt76]

● Accuracy level and axial clearance 
The precision grade of SFU series (precision ball screw standard stock) is JIS C7. Axial clearance below 0.005mm (C7). 
● Material and surface hardness 
Screw shaft and nut are adopted SCM415 (carburizing and quenching), the surface hardness of ball screw is HRC58 ~ 62. 
Low embellish smooth 
In order to prevent rust, sfu series (precision ball screw standard stock) products without shaft end processing are coated with anti-rust oil. Since the anti-rust oil does not have lubricity, please apply lubricant before use. 
● The standard thread rotation direction is dextrorotatory. The two shaft ends of the ball screw shall not exceed the diameter of the shaft bottom of the screw. 
● Effective travel can be customized, shaft end processing can be made according to the drawings.

Industry knowledge 
Ball screw is an ideal product for converting rotary motion into linear motion or linear motion into rotary motion. Ball screw consists of screw, nut and ball. Its function is to convert the rotating motion into linear motion, which is the further extension and development of the ball screw. The significance of this development is to change the bearing from rolling motion to sliding motion. Due to its low friction resistance, ball screw is widely used in various industrial equipment and precision instruments. Ball screw is the most commonly used driving element in tool machine and precision machine. Its main function is to convert rotary motion into linear motion or torque into axial repeated force. Meanwhile, it has the characteristics of high precision, reversibility and high efficiency. 
Processing process 
1. Raw screw rod shall be blanked by cutting machine and annealed by tempering machine (namely high-frequency heating equipment) according to processing requirements of screw shaft end. 
2. After annealing and cooling, the straight machine can roughly adjust the lead screw to ensure that the lead screw runout is controlled within the required range. 
3. After straightening the lathe coarse car, according to the actual situation to leave a certain precision margin. 
4. After the coarse car fine calibration, ensure that the screw beat control in a more accurate range. 
5. Fine calibration, lead screw center drilling, and then fine turning to the drawing requirements or external grinder grinding processing to the drawing requirements.
