● Accuracy Grade & Axial play

Accuracy grade of SG series (Standardized Precision Ball Screws) are based on JIS C3 and JIS C5. According to accuracy grade, Axial play 0(Preload: C3) and 0.005mm or less (C5) are in stock.

● Material & Surface hardness

SG series (Standardized Precision Ball Screws) consists of Shaft and Nut materials SCM415

(Carburizing and quenching) and Surface hardness is HRC58~62.

● Lubrication

SG series(Standardized Precision Ball Screws) without end-journal machining will be applied with anti-rust oil for rust prevention.

Anti-rust oil does not have lubricating function so that please apply Grease or lubrication oil when using the Ball Screws.

If there is no specific instruction, KSS would recommend our original Grease (MSG No.2) as standard lubricant.

Please feel free to contact us.

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.
