What Is a Guide Screw?

HIWIN ball screw (ball screw) has many advantages in use, such as high efficiency, reversibility, zero backlash, high rigidity, high lead accuracy and many other advantages, compared with the traditional Acme screw (ACME) For comparison, a ball screw (ball screw) adds steel balls between the screw and the nut. The sliding friction transmission of the traditional screw is replaced by rolling motion of steel balls.

HIWIN Ball Screw Features and Applications:

To greatly reduce friction losses, help maintain high efficiency and precision. The following details the characteristics and advantages of HIWIN Ball Screws.

Because the ball screw (ball screw) screw shaft and nut are rolling motions in point contact, its efficiency can reach more than 90%. Therefore, its transmission torque is only 1/3 of the traditional lead screw, and the mechanical efficiency of the ball screw is much higher than the traditional lead screw.

HIWIN ball screw (ball screw) adopts ultra-precision machining on the tooth surface to reduce the contact friction between the ball groove and the steel ball, and the rolling motion of the point contact between the steel ball and the ball groove, with low friction and high operating efficiency. The advantages. Therefore, the motor driving force requirement can be reduced, thereby reducing costs.

HIWIN uses high-precision testing equipment and follows standard test procedures to ensure the efficiency of ball screws.

CNC machine tools, IT and semiconductor equipment require zero backlash, minimum elastic deformation (high rigidity) and high smoothness for the transmission screw. This can be achieved through our special design. The ball screw (ball screw), HIWIN linear guide and HIWIN guide are preloaded to achieve the reproducibility of the Xinxin machine and the high rigidity of the full stroke. However, excessive preload will increase operating torque. Such increased friction torque will generate heat and reduce life expectancy. Through our special design and manufacturing process, we provide you with optimized ball screws-zero backlash and low heat loss.

HIWIN ball screw (ball screw) accuracy level is manufactured according to ISO, JIS and DIN standards. It can also be produced according to customer needs. A precision laser measuring instrument is used to ensure the accuracy of the ball screw, and a lead accuracy table is attached with each grinding-grade ball screw, giving 100% quality assurance.

Different from the traditional lead screw life depends on the wear of the contact surface; HIWIN ball screw (ball screw) depends on the fatigue failure of the material. In order to ensure the reliability of the HIWIN ball screw (ball screw) in the expected life, regardless of design, material, heat treatment and lead, etc., the most stringent professional considerations are adopted. The life expectancy of the ball screw (ball screw) must refer to several safety factors such as design quality and manufacturing process, but the most important is based on the dynamic load (C).

The basic factors that affect the dynamic load are: tooth profile accuracy, material characteristics and surface hardness. High-quality ball screws (ball screws) must reach a statistical B-class life (that is, 90% of the screws have reached the designed life), 50% of the ball screw life exceeds the design life value of 2 ~ 4 Times.

Because the traditional lead screw is the metal-to-metal surface contact, in order to overcome the starting frictional force, a high

Starting torque. Then the ball screw (ball screw) is in rolling contact with the steel ball, and only a small starting torque is required to overcome the friction. HIWIN uses the best tooth shape design factor (shape factor) and professional manufacturing technology to achieve the best true tooth shape. And

HIWIN guide rails use profile measurement equipment to monitor the profile of each process. This will ensure compliance with the set torque range.

High-quality machinery and equipment must still require low noise under fast feed and heavy load operations.

HIWIN strictly controls the circulation system and tooth design, assembly technology. The sales and service hotline of HIWIN ball screw is:

400-811-5568. And strictly inspect the surface precision machining and size to achieve the goal of low noise.

HIWIN uses the fastest process arrangement and inventory of ball screws (ball screws) to achieve the goal of short delivery time.

If a ball screw (ball screw) is used in the brake instead of the traditional pneumatic or hydraulic drive, many advantages can be obtained, such as no leakage, no filtering, energy saving and high reproducibility.
