Motion transmission of machine tools

According to the role played in cutting process, cutting motion is divided into main movement and feed motion.


Main motion: a working movement that forms the cutting speed of machine tools or consumes the main power.


Feed motion: the movement of redundant materials to be removed.


There is only one main movement in cutting process, and the feed motion can be more than one. The main movement and feed motion can be accomplished by cutting tools or workpiece separately, or by cutting tools alone. In addition to the cutting motion, there are also some auxiliary movements that must be carried out to realize the auxiliary work of the cutting process.


Machine tool transmission


The transmission mechanism of a machine tool refers to the mechanism that transfers motion and power, or is referred to as the transmission of machine tools.


According to the characteristics of transmission mechanism, the transmission mode of machine tool is divided into mechanical transmission, hydraulic transmission, electric transmission, pneumatic transmission and combined transmission of the above transmission modes. According to the adjustment characteristics of transmission speed, the transmission is divided into a class and a stepless transmission.


drive system


The transmission system is also called the transmission chain. He has first and two ends. The first end is also called the active part, and the end part is also called the follower. Every transmission system from the head to the end is composed of a certain transmission law, which is the transmission ratio, in order to ensure the performance of the machine tool. General machine tool transmission system can be divided into main motion transmission system, feed motion transmission system and fast empty stroke transmission system according to the nature of its movement. Generally understand the transmission system diagram.
