E40's Special Capabilities

E40(10000W/mm²)(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. The incision in XY direction tends to be uniform, Therefore, you will get a more even effect when drawing lines. E40 module adopts more stable and reliable optical solution, which makes the service life of the E40 continuous cutting mode 40% longer than that of the ordinary laser module, and the service life of the E40 normal working mode (8 hours per day) even reaches 7 years. The NEJE team's goal for E40 is to become the next classic, You can always believe that it will constantly brings you more amazing projects.

It is only necessary to maintain the window lens. Do not use a screwdriver to operate the position of the lens set inside the E40 module, otherwise the optical system will be damaged, causing irreparable damage. When cleaning the window protection lens, first remove the air tube adapter with a slotted screwdriver, then unscrew the cone type air nozzle and clean the window lens with alcohol. Do not unscrew the ring type window lens holder to prevent the lens from being exposed to the polluted environment, dust from entering the interior and damaging the optical system. Due to smoke or oil and water, the outside of the lens will stick to the surface, and the lens will be burned due to the accumulation of beam energy. Therefore, keep the habit of cleaning regularly When cutting MDF leather and other materials, it is necessary to reduce the cutting focus and add no less than 30psi air aid. The NEJE E40 module provides metal high-pressure air assistance without additional purchase. When the air compressor is used as the air source, an oil-water filter needs to be added. Ordinary oil-water separator cannot filter oil-water 100%, so it needs to be cleaned regularly (several hours). If you plan to use it to cut wood, leather and other materials for a long time, it is recommended to buy high-quality high-capacity oil and water filters. E40 module is suitable for matching with ordinary oxygen generator to protect window lens from pollution, and it is recommended to use together.

About High Pressure Air Assist

When do you need high pressure 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. If your project will produce more smoke, it is recommended to use an oxygen generator to protect the lens for a long time. If you are used to cut wood, MDF, cardboard, leather and other materials that produce a large amount of carbonized substances and need at least 30psi of air assistance, it is recommended to use the air valve accessories provided by NEJE to control high-pressure gas.
