3. Structure, function and working principle of main components or functional unit

3.1 Bed body part                          

Through the numerical control system to control its AC servo motor drive, the motor drive gear rack to achieve the Y direction of reciprocating motion, to achieve fast movement. The Y-shaft rack and linear guide rail adopt high precision products to effectively ensure the accuracy of transmission; control limited switches at both ends of the trip, and install hard limit device to effectively ensure the safety of the machine tool. The main engine is equipped with automatic lubricating oil to the moving parts of the bed to ensure the operation of the moving parts in good condition and improve the service life of the guide rail, gear and rack.

3.2  Cross member and X-axis and Z-axis device  

The beam eliminates the internal stress after annealing, and the vibration time is then processed after rough machining to ensure the rigidity and stability of the laser head moving member. X axis and Z axis are driven by high precision module. In the process of movement, the limit switch controls the stroke to limit, and there are elastic cushion mechanical limit at both ends to ensure the safety of the system operation.

The Z-axis device mainly realizes the upper and lower movement of the laser head. The upper and lower movement of the laser head is completed by the numerical control system controlling the servo motor, and the motor drives the linear module, which drives the upward and downward reciprocmovement of the Z-axis skateboard. The upper and lower ends use proximity switches to control the travel, to ensure the safety and reliability of the movement.

3.3 electric control system
