Laser engraving machine maintenance
1. Replace water and clean the water tank (it is recommended to clean the water tank and replace the circulating water once a week) Note: Before the machine works, make sure that the laser tube is full of circulating water. The water quality and water temperature of the circulating water directly...Read more -
The reasons and solutions for excessive vibration or noise of laser marking equipment
Reason 1. Fan speed is too high: The fan device is one of the main factors affecting the noise of the laser marking machine. Too high speed will increase the noise. 2. Unstable fuselage structure: Vibration produces noise, and poor maintenance of the fuselage structure will also cause noise probl...Read more -
Analysis of the causes of incomplete marking or disconnection of laser marking machines
1、Main reason 1）.Optical system deviation: The focus position or intensity distribution of the laser beam is uneven, which may be caused by contamination, misalignment or damage of the optical lens, resulting in incoherent marking effect. 2）.Control system failure...Read more -
The mainly reasons why the laser marking machine burns or melts on the surface of the material
1. Excessive energy density: Excessive energy density of the laser marking machine will cause the surface of the material to absorb too much laser energy, thereby generating high temperature, causing the surface of the material to burn or melt. 2. Improper focus: If the laser beam is not focu...Read more -
The main difference between continuous laser cleaning machine and pulse cleaning machine
1. Cleaning principle Continuous laser cleaning machine: Cleaning is performed by continuously outputting laser beams. The laser beam continuously irradiates the target surface, and the dirt is evaporated or ablated through the thermal effect. Pulse laser cleaning ma...Read more -
Causes and solutions for improper welding surface treatment of laser welding machines
If the welding surface of the laser welding machine is not properly treated, the welding quality will be affected, resulting in uneven welds, insufficient strength, and even cracks. The following are some common reasons and their corresponding solutions: 1. There are impurities such as oil, oxide...Read more -
Reasons and solutions for poor cleaning effect of laser cleaning machine
Main reasons: 1. Improper selection of laser wavelength: The main reason for low efficiency of laser paint removal is the selection of the wrong laser wavelength. For example, the absorption rate of paint by laser with a wavelength of 1064nm is extremely low, resulting in low cleaning efficie...Read more -
Reasons and optimization solutions for insufficient laser marking depth
Insufficient marking depth of laser marking machines is a common problem, which is usually related to factors such as laser power, speed, and focal length. The following are specific solutions: 1. Increase laser power Reason: Insufficient laser power will cause the laser energy to fail to effecti...Read more -
Laser welding machine has cracks in welding
The main reasons for laser welding machine cracks include too fast cooling speed, differences in material properties, improper welding parameter settings, and poor weld design and welding surface preparation. 1. First of all, too fast cooling speed is a major cause of cracks. During the laser ...Read more -
Reasons and solutions for blackening of laser welding machine welds
The core reason why the weld of the laser welding machine is very black is usually due to the incorrect airflow direction or insufficient flow of the shielding gas, which causes the material to oxidize in contact with the air during welding and forms black oxide. To solve the problem of blac...Read more -
Reasons and solutions for the laser welding machine gun head not emitting red light
Possible reasons: 1. Fiber connection problem: First check whether the fiber is correctly connected and firmly fixed. A slight bend or break in the fiber will hinder laser transmission, resulting in no red light display. 2. Laser internal failure: The indicator light source inside the laser may...Read more -
How to solve the burrs in the cutting process of the fiber laser cutting machine?
1. Confirm whether the output power of the laser cutting machine is sufficient. If the output power of the laser cutting machine is not enough, the metal cannot be effectively vaporized, resulting in excessive slag and burrs. Solution: Check whether the laser cutting machine is working normally. ...Read more
