E40 Laser Module RECOMMENDED REASON

E40 Built-in 2 Diodes,Dual beam Compressed Spot Module, NEJE E40 is a professional cutting module specially designed for long-term safety cutting processing. It is currently the strongest power and optical performance module with 2 beams. Compared with NEJE A40640, E40 is more focused on cutting stability, heavy-duty design, and easier to use air asisst, more stable output power for cutting, E40 also has good cutting efficiency, 300mm/min can cut 4mm plywood cleanly, NEJE has optimized the optical characteristics in the XY axis direction, so that the XY axis cutting is balanced and more suitable for cutting; remove it Air nozzle, E40 can also be directly used for engraving without air assistance, and the engraving ability of E40 is also very close to A40640. If most of your work is for cutting, choose E40.  If most of your work is for carving, choose A40640.

Notice： E40 is a fixed-focus module without a focusing lens. If you rotate the inner lens, it will destroy the optical system.

Due to there being only a high-temperature resistant window protection sheet in the middle to protect the lens, which can be replaced. It has a very small focusing spot. Therefore, the optical density is very high, and it is easy to engrave metal and stone, and even cut thin metal sheets(very thin). Another important use of E40 is to cut hard materials less than 5mm and recommend 3mm, such as leather, MDF board, and cardboard, which is the design goal of this module.

In addition, when using E40 to cut hard materials, it is recommended that the air pressure above 30PSI, the air source of ordinary oil-water filter needs to clean the lens regularly, otherwise it will easily damage the window protection lens.

E40‘S SPECIAL CAPABILITIES

E40(High Precision multi-function module) is a high-power dual beam fixed focus high-precision module. E40 module has extremely small incisions when cutting MDF boards, leather, acrylic, fabric, cardboard and other high-density materials less than 4mm, and the minimum gap between incisions is less than 0.06mm, At the same time, it can carve stainless steel, stone, glass, ceramics and other high-resolution materials with high-precision rendering capability, and the imaging effect is meticulous and accurate. It is a perfect high-power image rendering module. The NEJE E40 module adopts NEJE's unique external lens optical compression technology, which makes the focus energy density amazing, The energy density is 2 times higher than that of the 20W optical power module, so it has faster speed and precision in the actual engraving process.

Due to the built-in NEJE unique fiber compression technology, It has a very strong energy density (0.04x0.06mm with 12W+ pulse and 11W continuous optical power),  There are very special and top artistic expressions on the carvings of stainless steel grayscale carvings, stone carvings, Glass Carving, hardwood reliefs, canvas art, and other materials.  The A40640 is the only high-power module with variable focus section, The optimized A40640 II has higher cutting reliability, The short focus is suitable for carving hard materials such as metal stone and cutting materials with high density such as mdf, The long focus has better depth of field and smaller included angle for cutting thick wood and other materials. The excellent design makes the A40640 have a very strong vitality from the first creator of high-power diode laser to today, Due to the high power density, it has an equivalent application higher than 20W (optical power) laser in large area image engraving, If you only consider 1 module to help you solve all the needs, it is the best choice.

NOTICE

The NEJE A40640 module adjusts the focus to Long focal end by default. This is because the NEJE factory has to ensure the consistency of product testing.
When you receive the product, it is recommended to use a flat-blade screwdriver to adjust the focus to 2-3mm from the light shield.

It is normal for the A40640 module to be slightly non-uniform in the XY direction of the far focus. This is a compromise of zoom design, not a quality problem. You can reduce the non-uniform XY cutting by narrowing the focus.

The lens can be rotated with a flat blade screwdriver. prevent the lens from leaving the module and prevent dust from entering the interior to damage the optical system.

The outside of the lens will be stained with the surface due to smoke or oil and water, and the lens will be burned due to the accumulation of beam energy. Therefore, try to keep the habit of cleaning at the beginning of each use or after the introduction.

When cutting MDF leather and other materials, it is necessary to reduce the cutting focus, and add air assistance of no less than 30psi. The NEJE A40640 module gives away metal high-pressure air assistance, which does not require additional purchase.

When the air compressor is used as the air source, an oil-water filter needs to be added. Ordinary oil-water separators cannot filter oil-water 100%, so they need to be cleaned regularly (several hours) If you plan to use it for cutting wood, leather and other materials for a long time, it is recommended to purchase high-quality high-capacity oil and water filters Note that the ordinary oxygen generator can only be used for protecting the left and right of the lens. It is recommended to start it during normal engraving or ordinary cutting.

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.
