Classification and Maintenance of Water Chiller for Fiber Laser Cutting Machine

 In the working process of the fiber laser metal cutting machine, as the cutting time increases, the machine parts will generate heat. Failure to cool down in time will cause the laser power to gradually attenuate or even be damaged. In order to ensure the normal operation of the machine, reduce the number of machine parts. Replacement cost, the DIY fiber laser cutter is equipped with a water chiller for temperature control. As a circulating water device, the water chiller is responsible for cooling the laser generator and cutting the head. It is an important part of the metal fiber laser cutting machine. With the timely cooling of the water chiller, the normal operation of the desktop fiber laser cutting machine can be effectively stabilized, and the efficiency and the cutting speed of the thin plate can be improved under high-intensity work, ensuring the high-precision operation of the equipment, reducing the edge of the slit, and extending the laser generation The service life of the cutter, cutting head and fiber optic laser cutting machine saves the maintenance cost of the equipment and the replacement cost of accessories.

Commonly used brands of CNC fiber laser cutters are S&A and Tongfei. The desktop fiber laser cutters produced by our factory generally use S&A chillers, but customers can also choose Tongfei’s chillers, the model of the chiller, and the generator The power is consistent.

 

 

Water chiller model:

• S&A: 500W 750W 1000W 1500W 2000W 3000W 4000W 6000W 8000W 12000W

• Tong fei: 1000W 1500W 2000W 3000W 4000W 6000W 8000W 10000W 12000W

   

                

In order to ensure the stable operation of the CNC laser steel cutting machine, we also need to maintain the chiller regularly.

1. Regularly clean the heat sink. The cleaning method is: carefully brush the heat sink with a brush, and then blow it clean with compressed air. If necessary, clean and rinse with water and a special air-conditioning fin cleaning agent (common name dust).

2. Clean the condenser regularly (the method is the same as above).

3. Regularly check the water level in the water tank of the chiller. If the water level is too low, add pure water or deionized water in time.

4. Regularly check the electrical wiring terminals and remove dust (to be done after power off).

5. Regularly check whether the joints in the water system are leaking, whether the pipeline is aging, and if there is water leakage, replace the relevant components in time.

6. The water inside the chiller needs to be replaced regularly, and the general replacement frequency is one month. The water quality of the chiller is used for a long time and it is easy to form scale, which will block the waterway and cause the water flow to drop and reduce the cooling effect. Therefore, regular water replacement is treated as the primary problem. Regularly check the water quality in the water tank of the chiller. If the quality of the cooling water becomes poor, turbid, and its transparency decreases, all the deteriorated cooling water must be discharged in time and replaced with new cooling water. Try to choose distilled water, if there is no

Pieces can choose deionized water. Various manufacturers have requirements for water quality, so remember to meet the requirements, otherwise, long-term use of water that does not meet the standard will cause fouling inside the laser.

7. Regularly clean the impurities on the filter element of the chiller filter of the DIY fiber laser cutting machine. If the filter element is damaged, it should be replaced in time. The replaced filter element must use the standard filter element required by the manufacturer.

Transmission Mode and Advantages of Fiber Laser Cutting Machine

The working principle of the laser metal cutting machine is that a high-energy laser beam irradiates the surface of the workpiece to make the workpiece reach the melting point or boiling point, while the high-pressure gas blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, the material will finally form a slit, so as to achieve the purpose of cutting. In this process, what is the transmission mode of the fiber laser cutting machine? What are the advantages of using different transmission methods? Next, the MYST Laser will answer for you.

At present, there are two transmission methods used in laser sheet metal cutter: rack and pinion transmission and screw transmission. Both transmission methods have their own advantages and characteristics.

Gear/Rack and pinion transmission

The racks used in the laser steel cutting machine are also divided into spur racks and helical racks, which are paired with spur gears and helical gears respectively; the tooth profile of the rack is a straight line instead of an involute (tooth surface) In terms of the plane), it is equivalent to an infinite cylindrical gear with an index circle radius. Its working principle is that the rack and pinion are mechanical parts with teeth that can be mutually engaged. Rack and pinion are divided into straight teeth and helical teeth. Rack and pinion are widely used in laser cutting machines for the metal sheet to realize transfer movement, change movement speed, and change movement direction.

 

 

Advantages of rack and pinion transmission:

1. The instantaneous transmission ratio is constant, the work is stable, the transmission is accurate and reliable, and it can transmit the movement and power between any two axes in space;

2. Wide range of applicable power and speed, high transmission efficiency, reliable work and long service life;

3. The rack and pinion are relatively easy to manufacture, and the installation is relatively simple.

4. Small outline size, compact structure, suitable for long-distance load linear movement.

Ball screw transmission:

The ball screw transmission used in the CNC fiber laser cutting machine is an ideal product that converts rotary motion into linear motion or converts linear motion into rotary motion. The ball screw is composed of a screw, a nut, and a ball, and its function is to convert rotary motion into linear motion. Its working principle is the development of ball screw technology, which makes the bearing change from rolling action to sliding action. Because of its small frictional resistance, ball screws are widely used in various industrial equipment and precision instruments, as well as fiber optic laser cutter.

 

 

Advantages of ball screw:

1. High transmission efficiency;

2. The transmission is sensitive and stable;

3. High positioning accuracy;

4. Good accuracy retention;

5. High transmission rigidity;

6. Good synchronization performance.
