Maintenance Method Of CO2 Laser Cutting Machine

The stable operation of the machine is inseparable from the proper operation and daily maintenance. The following is a brief introduction to the daily maintenance of the laser cutting machine:

1. Water replacement and cleaning of the water chiller (It is recommended to clean the water chiller once a week and replace the circulating water once)

Note: The laser tube must be filled with circulating water before working.

The water quality and water temperature of the circulating water directly affect the service life of the laser tube. It is recommended to use pure water and control the water temperature below 35 °C. If it exceeds 35 °C, it is necessary to replace the circulating water, or add ice cubes to the water to lower the water temperature.

Cleaning the water chiller: first turn off the power supply, unplug the water inlet pipe, let the water in the laser tube automatically flow into the water chiller, open the water chiller, take out the water pump, and remove the dirt on the water pump. Clean the water chiller, replace the circulating water, return the water pump to the water chiller, insert the water pipe connected to the water pump into the water inlet, and arrange the joints. Power the pump separately and run for 2-3 minutes (fill the laser tube with circulating water).

2, the cleaning of the fan

The long-term use of the fan will cause a lot of solid dust to accumulate inside the fan, which will cause a lot of noise and is not conducive to exhaust and deodorization. When there is insufficient suction of the fan, the power supply is first turned off, the air inlet pipe and the air outlet pipe on the fan are removed, the dust inside is removed, and then the fan is inverted, and the fan blades are pulled up until it is clean. Then install the fan.

3, the lens cleaning   The most frequent maintenance task is cleaning the laser cutter’s lens and mirror. You should do this daily (or after about eight hours of use). A lot of dust and debris from cutting can settle on this part, and without proper cleaning, you risk the laser cutter not working properly or permanent damage to the lens and mirror.

 the equipment must be turned off)

There are three mirrors and one focusing mirror on the engraving machine (the No. 1 mirror is located at the exit of the laser tube, that is, the upper left corner of the machine, and the No. 2 mirror is located at the left end of the beam. The mirror No. 3 is located at the top of the fixed portion of the laser head, and the focusing mirror is located in the adjustable barrel of the lower part of the laser head. The laser is reflected by these lenses, and is focused and emitted from the laser head. The lens  is easily stained with dust or other contaminants, causing laser loss or lens damage. Do not remove the No. 1 and No. 2 lenses. Just wipe the lens with the cleaning solution carefully along the center of the lens. Edge rotary wipe. The No. 3 lens and the focusing mirror need to be taken out from the frame, and wiped in the same way. After the wiping is completed, it can be put back as it is.

Note: 1 lens should be wiped gently, can not damage the surface coating; 2 wiping process should be handled gently to prevent falling; 3 focus mirror should be installed to keep the concave surface down.

4, the guide rail cleaning (recommended to clean once every half a month, shutdown operation) 

Cleaning the linear guide: First move the laser head to the far right (or left side), find the linear guide as shown above, wipe it with a dry cotton cloth until it is bright and dust-free, plus a little oil (can use sewing machine oil, cut Do not use oil), slowly push the laser head a few times to allow the lubricant to be evenly distributed.

The guide rail and the linear shaft are one of the core components of the equipment, and its function is to guide and support. In order to ensure the machine has high machining accuracy, the guide rail and straight line are required to have high guiding precision and good motion stability. During the operation of the equipment, due to the large amount of corrosive dust and smoke generated during processing, the smoke and dust are deposited on the surface of the guide rail and the linear shaft for a long time, which has a great influence on the processing precision of the equipment. An etch point is formed on the surface of the linear axis of the guide rail to shorten the service life of the device. In order to make the machine work stably and ensure the quality of the products, it is necessary to carefully carry out the daily maintenance of the guide rails and linear axes.

Note: Please prepare the cleaning rails - dry cotton cloth, lubricating oil

The guide rails of the engraving machine are divided into linear guides and roller guides. In the YM series, linear guides are used in the X direction and roller guides are used in the Y direction.
