precision machinery-1929cc威尼斯

precision machinery can withstand, and guide rail fixed mobile device or equipment and a device for friction reduction. a longitudinal groove or ridge on the surface of a guide rail, used for guiding, fixing machine parts, special equipment, instruments, etc.. rail, also known as slide, linear guide, linear slide rail, for straight reciprocating motion of the occasion, have higher than linear bearing rated load, and can bear a certain torque, and can realize high precision linear motion in high load situations. high precision machinery the main quality indexes: guidance accuracy, precision of motion, enough rigidity, wear resistance, to the change of temperature not sensitivity and the structure of technology.
