Desktop engraving machine why moment is not deep, not fast

Desktop engraving machine understanding to the direct cause of laser material processing depth and the processing speed is the lack of: laser processing of the useful power density.

Desktop engraving machine for the same material, laser and operation depend primarily on the laser light power density in the processing load on material (attention: not power), the optical power density refers to the power in a unit area, calculated as: laser power density = laser power / laser facula area

The formula can be the treatment scheme of two class classification: increasing laser power or decreasing gathering spot size.

Desktop engraving machine to increase the final gather when the laser power:

1 see, laser cleaning pipe outlet. View, cleaning the lens, if the lens damage, should be timely conversion lens, molybdenum mirror we choose with old change new method, greatly reducing the user's use of cost, initiative user every half year forced conversion of a lens.

2 see light path is correct, in the transmission process of the laser beam, can have the following representation: laser with partially occluded. Laser in through the hole of an object, whether in the middle, if not in the middle, is a simple cause diffraction effect, reduces the laser power and quality. Increase the operating current, but impassable laser tube maximum working current, or laser power drops, 1.2m: 20mA, 1.6m: 22mA.

Can have been aging 3 laser tube, the need for a new tube

4 more power for laser tube with reduced aggregation point scale: for most places, reduce the laser spot size increase laser tube current or convert more laser tube is more useful, and lower cost.

The first element gathering spot scale desktop engraving machine has the following effect:

Desktop engraving machine view the incident to the laser spot quality gathered mirror: the incident to the laser beam quality is better aggregation lens focus, concentration of the smaller scale, the light power density is larger, if the incident to the spot quality gathered mirror difference, should take the following measures: from the laser tube at the aperture preliminary view, must be which link caused by laser spot quality qualitative difference, if caused by the mirror, mirror adjustment or conversion. If the laser tube part of light quality has deteriorated, it should adopt the following measures:

Desktop engraving machine check the length of the laser tube and support distance can adjust corresponding support, when necessary. Support of accurate distance: between the two supporting points for laser tube length 1/2, two were outstanding 1/4. To support the direction of the laser tube is not accurate, cause the laser tube deformation, multiple rotating laser tube, looking for a best supporting angle (direction).

Notice: rotating laser tube, should stop cooling water import equipment adjustment, adhere to the principles of laser beam incident \ "into higher low" to gather mirror can always straight in the middle: when the laser beam straight, median incident to focus quality gathered mirror is best, if the laser beam incident angles to gather mirror, gather quality decreased greatly, the focus will be sharply scale becomes large, light power density is significantly reduced, directly influence the cutting quality.

A. carefully check, adjust the lens optical path, so that the laser incident direction of four vertex angles of fixed and reliable, just arrived in this standard, in order to ensure the smooth process of laser power density on the all format operation.

B, the use of light path straight verification tool, carefully check, adjust the 3# mirror, the laser beam in the aggregation tube straight median incident to the aggregation of lens. Desktop engraving machine used for aggregation mirror focal length: (current common aggregation mirror F=50 \ \ 63.5 \\75mm three)
