The main body part of the machine is the motor execution part of the laser cutter, which determines the accuracy of the position and the speed of the machine, namely the speed of the laser cutting machine.As the domestic laser cutting machine manufacturer, the main body is the most core part.
The main body part of the machine consist of the bed, the beam, the Z axis , the worktable and the water, gas and oil system. By controlling the servo motors of X, Y and Z axis through the numerical control system, the reciprocating motion of precision, stability and high speed is realized.The precision movement part is sealed with a fully enclosed dust proof device to ensure the working environment, thus ensuring the service life of the main body part of the fiber laser cutting machine.
The main body part X and Y axes adopt original imported gear and rack driver and high precision linear guide rail. In the moving parts,we installed the famous brand of photoelectric sensor and mechanical stroke switch. At the same time, our machine designed with high strength elastic cushioning device, which ensures the safety of personnel and machine.
Ø Lathe bed part
The bed adopts the honeycomb structure, and then welded together.After the stress annealing treatment the next step is coarse processing; And then the treatment of the vibration aging process, and finally semi-finishing and finishing processing technology.The whole processing and manufacturing process completely solves the stress distortion caused by welding and processing.And we select the imported large CNC processing equipment to ensure the accuracy of the bed;Therefore, the precision and stability of the machine will ensured in future.
Ø Beam part:
Casting beams also adopts aviation aluminum material,and the same manufacturing technology and processing equipment as the lathe bed , so as to realize the the same change trend when machine in the process of various environment ,and reached high stability and precision.
Ø Z axis part:
The z-axis sliding seat is also cast by aviation casting aluminum, and the transmission part is driven by the servo motor and high precision screw and ball to realize the upper and lower reciprocating motion of the cutting head.The upper and lower ends are equipped with a photoelectric sensor switch and elastic cushion to ensure the safety of the movement.
There are two kinds of control mode for Z axis reciprocating movement: one is the NC interpolation motion shaft alone, the other is that the capacitive sensor detect the cutting nozzle to the plate surface distance, and then feedback signals to the control system of servo control.Two modes of control complement each other;Thus guaranteed the high accuracy of laser cutting, the stability of cutting quality and the quality of cutting section.
Ø Water,Gas and oil part:
The water part is for cooling the fiber laser, the professional fiber laser chiller will be low energy consumption and long life.
The gas circuit of the fiber laser cutting machine is divided into two applications: the auxiliary air circuit, such as the compressed air used to drive the cylinder.The other is for cutting.
The cutting gas is divided into three types: nitrogen, oxygen and air, and the three gases are freely chosen to switch through the solenoid valve.Nitrogen is mainly used for cutting stainless steel and aluminum plates.Oxygen is mainly used to cut carbon steel plate.Air can cut all metal, and greatly reducing the cost of equipment usage.
The oil system adopts automatic lubrication. Each transmission point does not need to be lubricated manually, we only need to add to lubricating oil pump in the fixed time.
