How to maintain the laser cutting machine

Lens cleaning method: When cleaning the lens, ethanol or 98% alcohol must be used as the cleaning solution, and a small amount of absorbent cotton shall be lightly dipped with alcohol, and then placed on the lens.

Gently scrub the lens directionally, and then wipe the lens with dry cotton cloth to make the lens bright and transparent.

Note: If you scrub too hard, it is easy to wipe off the coating on the lens until the lens is damaged.

Cleaning method of guide rail: first remove the dirt on the guide rail, and then treat the crushed materials, add a little clean lubricating oil on the guide rail, and move the guide rail to make the clean lubricating oil evenly distributed on the guide rail. Be careful not to thicken the lubricating oil (butter). This kind of lubricating oil attached to the guide rail is easy to cause adhesion and distortion of processed materials and dust, thus damaging the slider and guide rail.

Cleaning method of working platform. There are ferroalloy, honeycomb briquette, caterpillar, knife bar and other zinc on the working platform. Clean up the processing waste on the working platform first. Crawler type worktops need to be treated with a bit of clean antirust oil after six months of use. Other worktops do not need it.

Note: The working platform cannot be cleaned easily with water. It is easy to rust the working platform and accelerate the oxidation of work.

Correct operation procedure for maintaining the focusing lens of laser cutting machine

1. Take out the focusing lens from the frame: loosen the fastening screws, take down the air nozzle and the lens barrel in turn, and blow off the dust on the lens surface with a blowing balloon first.

2. If it is really necessary to clean the lens, only a laboratory grade paper soft cotton ball can be used, dipped with an appropriate amount of acetone or high content of alcohol, and gently rotated clockwise from the center of the lens to the edge. If necessary, both sides of the lens need to be cleaned. Pay attention when scrubbing.

3. Install the lens barrel and air nozzle, adjust the focus, tighten the fastening screws, and keep the convex face downward when installing the focusing lens.

Pay attention to the following three points when maintaining the focusing lens of the laser cutting machine kit

1. The focusing lens material is ZnSe (arsenic zinc), which is brittle and is afraid of falling; Attention during disassembly: Do not use excessive force or collide with hard objects. There is a layer of anti reflective film on the surface, which is afraid of pollution, moisture, greasy and scratches; Therefore, dry and degreased air shall be provided during operation. Do not operate the focusing lens directly by hand, because the skin is oily. This will damage the lens surface. Instead, you can wear gloves and its special suit to operate. For smaller lenses, it is more convenient to use optical tweezers or vacuum tweezers. No matter what method is used to clamp the focusing lens of the laser machine, it can only be clamped along the non optical surface, such as the frosted edge of the plaque.

2. Under normal conditions, it is necessary to check the condition of the focusing lens before use and before and after cleaning. Due to the relatively small size of most contaminants and surface defects, we often need to use magnification equipment when checking lenses. In addition to the amplification equipment, sometimes we also need to use relatively bright light to illuminate the optical surface to enhance the specular reflection intensity of surface pollutants and defects, so that pollutants and defects can be found more easily.

3. When cleaning the focus lens, always use clean wiping paper and optical grade solvent to prevent damage by other pollutants. Wiping paper must be soaked with appropriate solvent and cannot be used dry. Considering the softness, the available wiping paper is pure cotton wiping paper or applicator, such as cotton ball, lens tissue and cotton swab.
