With its excellent performance, ball screws are widely used in occasions that require precise linear motion: CNC machine tools: X/Y/Z axis feed drive of machining centers, lathes, milling machines, and grinders. Semiconductor manufacturing equipment: Precision positioning platforms in lithography machines, wafer cutting machines, and packaging equipment. Industrial robots: Joint drives, linear motion modules. Electronic manufacturing
Compared with sliding screws and other linear transmission methods, ball screws have incomparable advantages: High efficiency: The transmission efficiency is as high as 90% or more (sliding screws are usually less than 50%), which means smaller driving torque and lower energy loss, significantly saving energy and reducing motor load. High precision and high rigidity: The
In the fields of modern industrial automation, precision machine tools, semiconductor equipment, medical equipment, etc., ball screws play a vital role as key transmission elements that convert rotary motion into precise linear motion. Their excellent performance and reliability are the core guarantee for improving equipment accuracy, efficiency and life. Ball screw: working principle and core

Linear guides use balls and rollers for transmission. Their advantages are high precision, large load and torque. Many linear guides are made of 55# steel and chrome bearing steel, such as GCr15. Carburized bearing steel, such as G20CrMo, can also be considered. Linear guides are easy to install and interchange. They use precision processing technology,
Micro Guide Rail Due to the vigorous development of the global semiconductor machinery and equipment industry, the electronics industry and its surrounding industries, the industry has higher and higher functional requirements for the miniaturization and high density of products. Because of the current micro guide rails, the smallest linear guide rail slide has a width
1.Positioning accuracy In terms of accuracy, the linear guide transmission mechanism reduces the problem of interpolation lag. The positioning accuracy, reproducibility, and absolute accuracy are all easier to achieve through position detection feedback control than rotary motor + ball screw. 2.Repeatability accuracy comparison The transmission mechanism is simple, reducing the problem of interpolation lag. On
