Machine tool movement
According to the role played during the cutting process, the cutting motion is divided into a main motion and a feed motion.
Main motion: It is the working motion that forms the cutting speed of the machine or consumes the main power.
Feed motion: A work movement that causes the excess material of the workpiece to be continuously removed.
There is only one main motion during the cutting process, and the feed motion can be more than one. The main motion and the feed motion can be performed separately by the tool or the workpiece, or by the tool alone. In addition to the cutting motion, the movement of the machine tool also has some auxiliary movements that must be performed to assist the cutting process of the machine tool.
2. Machine drive
The transmission mechanism of the machine tool refers to the mechanism that transmits motion and power, referred to as the transmission of the machine tool.
According to the characteristics of the transmission mechanism, the transmission mode of the machine tool is divided into mechanical transmission, hydraulic transmission, electric drive, pneumatic transmission and the combined transmission of the above several transmission modes. According to the characteristics of the transmission speed adjustment and change, the transmission is divided into a stepped drive and a stepless drive.
3. The drive system of the machine tool
The transmission system is also called the transmission chain. He has the first and last end pieces. The head piece is also called the active part, and the end piece is also called the follower. Each transmission system consists of a certain transmission law from the head end piece to the end piece. This is the gear ratio to ensure the performance of the machine tool. The general machine tool transmission system can be divided into three types: the main motion transmission system, the feed motion transmission system and the fast air travel transmission system according to the nature of the motion it is responsible for. You can generally understand the drive system diagram.
Flexible lift gate is a flexible soft curtain door, inside and outside the two curtains, curtains used between the aluminum beams connected with a vertically movable rail, the roof beams have levels not in the same straight line and hangar large plants in particular be applicable. Flexible lift door installation does not take up interior space in the hole inside. When the fiest move to open the door, and finally superimposed over the hole. Off event curtain rail first and then fall down until it is completely closed.
