How do we choose the right ball screw?

How do we choose the right Ball Screw? WKT has the following suggestions.
1. Model selection

The model mainly refers to the diameter and lead of the ball screw. According to the machining requirements, accuracy and technical requirements of the machine tool, the model that is definitely needed should be initially determined. Finally, remember to check, and the final shape can only be finalized if the design meets the requirements.

2. The selection of the lead accuracy of the ball screw

Because the accuracy parameters of the ball screw will have a direct impact on the processed parts, it is generally only necessary to pass the accuracy check if it meets the requirements. Another point is that the ball screw is divided into several accuracy grades, which are selected according to customer requirements. The common ones are C5 and C7 precision, C5 is grinding grade, C7 is cold-rolled, and precision C5 is better than C7.

3. About the choice of the support method of the ball screw

In the process of designing the equipment, the support method of the ball screw usually chooses "fixed-support" or "fixed-fixed". The "fixed-support" support method is relatively easy to assemble, with good rigidity and high accuracy. It is mainly used in environments with medium speed, large stroke and heavier load; the "fixed-fixed" support method is relatively difficult to assemble. It has good rigidity and high precision, and it is often used in the environment of high speed, large stroke and heavy load.
