Welcome to inquire! Contact: Chen Zujiang. The emergence of different optical axis, the life we ??are talking about the optical axis, the general use of the optical axis are industrial machinery, such as linear axis linear optical axis rails, hollow axis and so on. As they have different names, like different axis has its different uses. Some used in hydraulic pneumatic, engineering machinery, automobile manufacturing rod, plastic rod guide pins and machinery, packaging machinery, printing machinery rollers, textile machinery, transportation machinery, as well as some of the major types of electronic equipment used / guide rod drive shaft linear axis manufacturers, pillars, other places like textile, die-casting machines, injection molding machines, slip devices also have a very good application Buy linear axis, but overall, because they wear resistance, rust, high precision linear axis, strength and other characteristics, in the machinery industry is very active. The ball screw is rotary motion into linear motion, or linear motion into rotary motion of the desired product. Ball is the most commonly used on the transmission element of machine tools and precision machinery, and its main function is to convert rotary motion into linear motion, or to convert torque into axial force again, while both high-precision, reversibility and high efficiency. With little friction, ball screws are widely used in various industrial equipment and precision instruments.
