What are the differences between ground ball screws and rolled ball screws?

The difference between ground ball screws and rolled ball screws lies in the different processing methods. Ground ball screws are manufactured by mechanical processing, while rolled ball screws use a one-time forming method. Grinding ball screws are targeted at industries with higher precision requirements, and their use costs are higher. The precision of rolled ball screws is low, and the cost is low when used in industries that do not require high precision.

Rolled ball screws are cold-rolled and have very low precision, usually C7 precision. Better manufacturers can barely achieve C5 precision, but one advantage is that the production cycle is short and the delivery time is fast. The production process of grinding-grade ball screws is relatively complicated. They are ground using ultra-precision grinding machines and require quenching in the middle. The accuracy can reach the highest grade C0, but the delivery time is very slow.

Our company's grinding ball screw processing cycle is usually 30-35 days. In peak seasons when orders are large, it needs to be postponed for about 5-10 days. The rolling ball screw processing cycle is very short, and the construction period is usually about 5-7 days ( Orders must be placed in the order in which they are placed).
