1.Machine frame structure

• Gantry steel structure welded bed, large tempering furnace overall annealing eliminates internal stress, good rigidity, stable and non-deformation (no need to make foundation)
• The overall welding form, the thickness of the main plate is better than competitors, the heaviest frame in the same model in the industry, and the long-term stable operation of the equipment can be guaranteed without the foundation, and the debugging cycle can be shortened
• The overall annealing of the welded bed is stress-relieving treatment, the rack surface deformation is ≤25μm

• High-strength and lightweight beam design optimized by finite element analysis to minimize weight under the premise of ensuring structural rigidity.Ensure high dynamic response;

• Imported large-scale CNC equipment processing to ensure the position and dimensional

tolerance of each mounting surface, achieving accuracy beyond design standard

• There is a dust extraction and exhaust system inside the bed. The cutting area is equipped with a partition dust removal and smoke exhaust device. When the cutting head is cut in each zone, the cylinder will close the other parts of the bed, effectively discharge the dust from the cutting area, and the bottom of the cutting area is filled with waste. The car can be pulled out regularly to clean up the waste.
• The upper rail structure protects the rail from the impact of laser processing and splashes,

prolonging the service life of the machine;

• Gear rack and linear guide adopt closed dustproof device; adopt Japanese THK high precision linear guide, German ALPHA rack and pinionAnd low backlash reducer, the parallelism error of the guide rail is less than or equal to 0.03mm, ensuring long-term motion accuracy;

• The precision optical inspection instrument is used to control the processing and assembly precision, and the limit switch control at both ends of the stroke is combined with the buffer mechanism on both sides, which effectively ensures the safety of the machine tool movement;

• The three-dimensional protective cover design effectively blocks laser radiation and has good safety.

2.Beam

• Y-axis beam is a high-rigidity and large-section structure, optimized by finite element analysis, light weight and good dynamic performance;
• The steel beam is laser welded, with small deformation and high welding strength; the overall vibration after welding is de-stressed to ensure long-term stable operation;
• An organ-type protective cover is installed on the beam to ensure that the rack and linear guides operate in a closed environment and are not affected by the external environment.
• Unique mechanical design-bed
• The rack and pinion and linear guide adopt closed dust-proof device; adopt imported brand high-precision linear guide, low-backlash reducer, rack and pinion, guide rail parallelism error ≤0.03mm to ensure lasting movement accuracy; adopt precision optical inspection instrument , The whole process controls the processing and assembly accuracy; the two ends of the stroke are controlled by limit switches, and the two sides are supplemented by buffer mechanisms, which effectively ensure the safety of the machine tool movement

3.Hydraulic lifting type exchanging worktable

• Hydraulic lifting type exchanging worktable
• The workbench is an integral welded structure with good strength and stability;

• The hydraulic lifting table adopts synchronous motor to realize four-cylinder hydraulic    synchronous lifting, with large load and low failure;

• Compared with the upper and lower two-layer exchange table, the cutting surface is always at the same height, and the Z-axis stroke only needs to be controlled at 100mm ~ 120mm; one can meet the high-speed cutting, and the second is to cut the distance between the plate and the damper. The dust removal effect is better.

• The exchange worktable consists of an exchange device and two movable worktables: the  exchange device is fixed on the back of the bed, the worktable exchange speed is fast, the working area and the exchange area are automatically positioned to ensure the repeating processing precision;
• Introduce multi-stage variable frequency deceleration function and use encoder feedback control to ensure exchange efficiency and stability.

4.Z axis anti-collision device

• Z-axis device is to achieve the up and down movement of the cutting head. After the capacitance sensor on the cutting head detects the distance from the cutting nozzle to the surface of the sheet, the signal is fed back to the control system, and then the control system controls the Z-axis motor to drive the cutting head to move up and down, thereby controlling the distance between the cutting nozzle and the plate, and effectively ensuring the cutting quality;
•  The anti-collision design of the cutting head effectively avoids possible mechanical    damage during accidental collision between the cutting head and the workpiece, and reduces the cost of the customer;
• Z-axis adopts Japan NSK precision ball screw, Japan THK linear guide, stable operation and fast response.
• Yawei patent, unique cutting head all-round protection technology
• When it collides with the cutting workpiece, the cutting head part detaches itself, which can quickly restore the cutting state

5.Gas and water path system

• The gas path system of the fiber laser cutting machine consists of two parts: one part is the cutting gas supplied to the cutting head, there is clean and dry compressed air, oxygen and nitrogen; the other part is the auxiliary gas, which is clean and dry compressed air, used for Partition cylinders during ventilation and the working table clamping cylinder, etc.;
• The cutting gas is divided into three kinds of gases: nitrogen, oxygen and air. The high and low pressures of the auxiliary cutting gas are all controlled by the servo proportional valve, which improves the cutting quality and cutting efficiency;

• The processing cost is greatly reduced for the user, by using air-cutting for thin carbon steel sheets and stainless steel and aluminum alloy.                        

• In addition, the pressure sensor is installed in the cutting gas system to ensure that the machine can stop working in time when the gas pressure is insufficient, and avoid the invalidation of the cutting parts. The pressure threshold can be adjusted by the pressure sensor.

• The waterway system consists of two parts: a part of the cooling water comes out of the chiller and enters the laser. After cooling the laser through the radiator inside the laser, it returns to the chiller. After a part of the cooling water comes out of the chiller, it enters the cutting head of the laser machine. Return to the chiller after cooling.

• If air cutting is often used, to achieve better cutting results, it is recommended to add a cold dryer (as shown in the figure above); the dryer can forcibly cool the compressed air below the required dew point, so that it contains A large amount of water vapor and oil mist are condensed into droplets, which are separated by gas and liquid, and are discharged from the outside of the machine by a drain to dry the compressed air.
