CNC woodworking machine fault point

Laser CNC woodworking engraving machine failure point

Laser CNC woodworking engraving machine needs attention and maintenance. Matters needing attention and maintenance. Engraving machine common faults

1. Short circuit, poor bearing spindle motor, rotor, sliding wire, etc.

2, limit switch, limit switch line is not good

3, Z-axis bearing is easy to break, the coupling open often leads to Z-axis knife or shadow

4, easy pump ring or no water

5, compass, easy to scratch after half a year

6, Z-axis screws will have a walking sound when running for a long time, frequently moving up and down

7, Z-axis and Y-axis dust-proof soil is too much

8, X-axis and Y-axis screw nut easy to fall, the wire is easy to loose
The inverter is easy to short
9, the stepper motor does not turn, easy to break the inter-cell space
Safety should be taken when using CNC woodworking engraving machine
10, computer engraving machine signal can not be transmitted


1. The laser tube mounting fulcrum of the CNC woodworking engraving machine is reasonable, and the protection should be in the quarter of the total length of the laser tube, otherwise the laser tube speckle pattern becomes bad, some work in a period of time into several Point, so that the laser power drop can not meet the demand, leading to the use of the tube, continuous reading of the laser tube, the prospect of the sale of laser CNC woodworking engraving machine is very good.

2, cooling system, often clean the water tank, water, cooling temperature control tank temperature control point should be reasonable, otherwise the cohesive strength will deteriorate and the laser tube is easily damaged, the pipe head loss, shorten the service life of cold water, sometimes does not work, resulting in the switch tube.

3, water conservation should be regularly cleaned and inspected, cooling water can not be often used with boiling water float switch or water protection float switch is no longer one, liquid separation is not used. The cooling water has good water quality, and the water outlet and alumina are serious. After using for a period of time, the water pump and water pipe will be cleaned regularly to prevent water accumulation or laser tube bursting or cold head loss.

4. The inhalation device should be regularly inspected and cleaned to clean the fan duct. Otherwise, a large amount of smoke will not be emitted, which seriously contaminates the lens and the laser tube, making each mechanical and electronic component susceptible to undesirable contact oxidation.

5, focusing lens and mirror inspection work for a while frame fever, lens surface discoloration rust; stripping crack is an alternative, especially for many customers atmospheric pump and air compressor, so the water quickly focuses on the lens, so the lens must be inspected on time ( Light laser nozzles) The cleanliness and quality of the optical system.

6, the working environment of the machine can not be too bad, if the ambient temperature is higher than 30 degrees, less than 18 degrees, too much dust, serious air pollution, serious damage to the machine, the failure rate is rising, the electrical accessories in the humid environment is prone to problems. Therefore, we especially remind our customers to improve the working environment and maintain the machine regularly.

7, grid-connected power supply. The power distribution and contact points of the complete set of equipment accessories are good (fans, water coolers, laser machines, laser power supplies, computers to independent power supplies), and the sales prospects of laser CNC woodworking engraving machines are very good.

8, the laser tube operating current is reasonable, can not grow in 90-100 years working light intensity, reasonable application of laser and laser energy saving; clean optical path system is correct, otherwise laser tube, premature aging and rupture so powerful laser machine working time It should be adjusted at 50 - 60%, and then adjust the working speed according to the material, which is the best working condition of the laser tube.

9. The processing of the substrate and materials should be smooth, otherwise the focal length will be inconsistent. In some places, it will not be worn, which will increase the intensity of light and cause rapid aging of the laser tube.

10. The heat supplied by the laser should be unimpeded, otherwise the operating current will increase to 50% or higher, so the laser power supply has a high failure rate. Just as the TM series machines can disassemble the side doors, the power directly releases the heat.
