ABOUT AIR ASSIST

When do you need air assist?

Air-assisted engraving or cutting can only be used for engraving or cutting that produces more carbonized substances. Generally, the depth of engraving is less than 1mm, and the cutting of plywood less than 2mm does not require air assist. A small fan can be used to blow off the smoke generated by the engraving. Air assist is not recommended when engraving images, and adding air assist at this time will destroy image details.

What kind of air pump is suitable for cutting?

The main meaning of air assist is to blow off the carbonized material produced by cutting, and the general oxygener and electromagnetic inflator have almost no meaning. only the pressure of the oil pump and air compressor (0.4-1.5mPa) has the effect of blowing away the carbonized material. but it should be noted that the air of the oil pump contains oil and cannot be directly used for the air-assisted module of the closed cavity, otherwise the oil will contaminate the lens, resulting in power drop or damage to the lens. The air pressure of the air compressor can be used for a short time with the closed cavity, but When used for a long time, the water-containing gas will contaminate the lens, cause the power to drop, and even damage the lens.

How to add air assist on the A40640 laser module?

The NEJE A40640 module is an adjustable focus module. For the consistency of testing, the NEJE factory adjusts the module to 55mm focal length by default. This focal length is suitable for cutting thicker materials. This focal length is generally not commonly used. When you are suitable for the first use of the product, it is recommended to use a flat-head screw to adjust the focal length to about 30mm, which is 1-2mm away from the light baffle. This focal length has a very high focal power density and can directly engrave grayscale stainless steel images gray-black stone and other hard materials, NEJE A40640 can directly engrave 3D hardwood and other materials, and does not require air assistance, due to the high energy density design, A40640 can directly vaporize general wooden materials during the engraving and cutting process, so it is also unecessary to add air assist.

Clearer of the engraving and cutting effect

The NEJE A40640 module is the benchmark for diode lasers. Since A40640 was released in 2020, as the inventor of the world's first diode laser module, its product performance cannot be surpassed so far. The mature and high-efficiency optical system design enables the output power to reach 10w -12w,  NEJE A40640 laser module has a minimum focus of 0.04mm and a maximum cutting thickness of 20mm. Combined with NEJE automatic air assist, in the multi-layer control mode of the lightburn software, you can Complete grayscale, 3D, high-quality cutting and other processes at one time. And the cutting angle is smaller, the cutting edge is more vertical and cleaner. The 204g lightweight design make the motion inertia smaller and the image clearer .

More reliable, The new laser uses a high temperature (1000℃) window glass to protect the lens, which effectively improves the service life of the lens.

Safer module design, NEJE has greatly enhanced the anti-static and surge design under the new control system. NEJE has passed the very severe test in the experiment, which has greatly improved the reliability of the NEJE control system. The new system does not require additional grounding to protect equipment.

Quiet design, NEJE A40640 module built-in NEJE unique intelligent drive design, so that the fan status can be automatically controlled.

The strongest diode engraving module, 12W pulse power in 0.04×0.06mm

NEJE A40640 module has ultra-high energy density at 30mm focus, which is beyond the reach of other imitators. It does not require air assist when carving wood with a depth of less than 1mm, and can completely vaporize the material through plasma effect. Ultra-high energy The density can also directly engrave grayscale image on stainless steel planes, which cannot be achieved by 4 x beam 20W diode lasers.
