Product Description

NEJE A40640 CNC Laser Module head fit Laser engraving cutting machine Engraver





WHAT NEJE A40640 CAN BRING TO YOU?

A40640 (The most widely used module) is a classic creative master dual beam zoom laser module, it is the world's first 2 beam laser diode engraving and cutting module with zoom design, with the best metal engraving ability, fast groove engraving ability, thick material cutting compatibility, Make it the most widely used module. 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 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
