Ball Screw is an ideal product that converts rotary motion into Linear Motion, or converts linear motion into rotary motion. The ball screw is composed of a screw, a nut and a ball. Its function is to convert rotary motion into linear motion, which is a further extension and development of ball screws. The important significance of this development is to change the Bearing from rolling motion to sliding motion. Because of its small frictional resistance, ball screws are widely used in various industrial equipment and precision instruments.
Most of WKT ball screws are made of No. 45 steel.
No. 45 steel is a commonly used medium-carbon quenched and tempered structural steel. The cold plasticity of this steel is generally better. Annealing and normalizing are better than quenching and tempering. It has higher strength and better machinability. After proper heat treatment, a certain degree of toughness, plasticity and wear resistance can be obtained. Material source convenient. It is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheat before welding and stress relief annealing after welding
In order to better wear resistance and maintain excellent processing performance, the heat treatment of the ball screw is a very important step. Heat treatment process steps of ball screw:
