Does laser engraving last?

Laser engraving has limitations in practical use, not all materials are suitable for laser engraving, because the place where the laser passes is easy to produce high temperature, leading to material degeneration or oxidation. The direct reason for the lack of laser processing depth and processing speed is that the effective power density of laser processing is small. For the same material, the laser processing effect mainly depends on the optical power density loaded on the processing material (Note: not power). The optical power density refers to the power per unit area. The calculation formula is: laser power density = laser power / laser spot area. From the formula, the following solutions can be classified into two categories: increasing the laser power or reducing the focus spot size.

VDIAO micro engraving laser engraving machine maintenance guide

1、 Add lubricating oil to linear guide rail:

VDIAO micro engraving laser engraving machine has been used for a period of time. The smoke and dust produced by engraving and cutting can corrode the guide rail, so the guide rail should be maintained regularly.

Turn off the power of the laser engraving machine, clean the guide rail with a clean soft cloth, and then drop lubricating oil on the guide rail. After the oil is added, let the slider roll back and forth on the guide rail to ensure that the lubricating oil enters the inside of the slider. After oiling, let the slider roll back and forth on the guide rail. At this time, install the guide rail first. Pay attention not to fix the guide rail first. Install all the fixing pins and keep them level. After fixing the belt and the slider, install the lens and adjust the X direction.

2、 Mirror | focusing mirror wiping:

VDIAO micro engraving laser engraving machine | after the laser cutting machine has been used for a period of time, smoke and dust will adhere to the surface of the lens, affecting the depth of engraving and cutting, as well as the accuracy of engraving and cutting. Generally, in a week or so (according to the use frequency of VDIAO micro engraving laser cutting machine | engraving machine), wipe three mirrors and one focusing mirror carefully with anhydrous alcohol.

3、 Bearing oiling:

A large number of bearings are used in VDIAO micro engraving laser cutting machine. In order to ensure good cutting and engraving effect, some bearings need to be oiled regularly (except oil bearing). Clean soft cloth is used to wipe off the clay on the bearing. The oil is sucked into the needle tube with a needle tube, and then slowly injected into the bearing with a needle. When oiling, slowly rotate the bearing

4、 Timing belt (belt) tightness adjustment:

There are several synchronous belts in the drive system of VDIAO micro engraving laser cutting machine. If the synchronous belt is too loose, the engraving characters will appear ghosting. If the synchronous belt is too tight, the synchronous belt will be worn. After using for a period of time, please adjust the tension screw of the timing belt, adjust the timing belt to the appropriate tightness, the engraving text does not appear ghosting, and the operation noise of the laser engraving machine and laser cutting machine is very low, or consult the micro engraving laser technician.

5、 Laser tube maintenance:

The laser tube in VDIAO micro engraving laser engraving machine is cooled by circulating water. After long-term use, there will be some white scale in the tube. We can add a small amount of vinegar into the circulating water to remove the scale in the tube, and then use clean water to wash the inside of the laser tube
