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.
The primary function of air assist is to blow away the carbonized material produced during cutting. using a standard oxyhydrogen torch or electromagnetic inflator is essentially pointless in this regard.Only the pressure of the oil pump and air compressor (0.4-1.5mpa) has the effect of blowing away the carbonized material.It should be noted that the air from 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.
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 first use the product, it's recommended to use a flathead screw to adjust the focal length to approximately 30mm, which is 1-2mm away from the light baffle.ThisFocal pointLengthHasItVeryHighFocal pointPowerDensityAndCanDirectlyEngraveGrayscale.Stainless steelSteelImagesGray–blackStoneAndOtherHardMaterialsNeje.A 40640CanDirectlyEngrave3 dHardwoodAndOtherMaterialsAndDoesNoteRequireWaterSupportTwoToTheHighEnergyDensityDesignA 40640CanDirectlyVaporizeGeneralWoodenMaterialsDuring theTheEngravingAndCuttingProcessSoItIsAlsoUnnecessaryToAddWaterAssist.
