How about the precision of ball screw processing
2024-07-03
Ball screw is a commonly used transmission device, which achieves high-precision linear motion through the rolling of the ball. In the field of industrial automation, ball screws are widely used in various mechanical equipment. So, how high is the precision of ball screw processing?
To understand the reasons for the high precision of ball screw processing, we need to understand the process of ball screw processing. Generally speaking, the process of ball screw machining is divided into four steps: turning, grinding, welding and adjustment. Among them, grinding is one of the key steps of ball screw processing, through precision grinding process can achieve micron-level processing accuracy. Welding and adjustment is to ensure the quality and durability of the ball screw.
The accuracy of the ball screw is mainly reflected in two aspects, one is the axial accuracy, and the other is the radial accuracy. Axial accuracy refers to the axial motion error of the ball screw under load, which is usually required to be below 1%. Radial accuracy refers to the jump error of the ball in motion, usually in the micron level.
In the process of ball screw processing, the accuracy not only depends on the level of production equipment and process control, but also takes into account the selection of raw materials and the performance of processing auxiliary equipment. For example, the tools, fixtures, measuring instruments and other equipment used in ball screw processing need to have high precision and stability to ensure that the processed ball screw has good quality.
In general, in the field of modern industrial manufacturing, the precision of ball screw processing has reached a very high level. At present, many manufacturers at home and abroad have adopted digital and automated production methods to improve the machining accuracy of ball screws. It is believed that with the continuous progress of science and technology, the machining accuracy of ball screw will continue to improve, providing better support and guarantee for the development of industrial automation.
