Product Introduction

◆ MRJ-Laser 20w dynamic focus laser engraving machine (AKA 3D laser marking machine) selects the pre-aggregation optical form and uses a larger X,Y axis deflection lens, so it can promise to conduct a larger laser spot, better aggregation accuracy and better energy effect. If the 3D marking and 2D marking is under equal aggregation accuracy operation, the former's marking scale can be larger.

◆ Only by setting the shape of the workpiece in advance, the focal length, printing position and shape change of different product orientation can be changed by only switching the settings. No need to move the workpiece.

Product Application

◆ Deep carving

Traditional 2D marking objects have inherent shortcomings in the appearance of deep carving. With the upward shift of laser focus in the process of carving, the laser energy acting on the practical appearance of objects will decrease sharply, which seriously affects the function and power of deep carving. The traditional deep carving method is that the electric method moves the lifting table to a certain height every certain time during the carving process to ensure that the laser appearance gathers outstanding.

◆ Color carving

In the same plane, it can mark or engrave on the black and white, or even realize multi-color marking, the role is more rich. With regard to the blackening of general metal surfaces, such as anodic alumina, it is usually the use of higher frequency pulses at suitable energy to mark under certain defocus conditions. Defocusing interval significantly affects the energy dispersion and color effect of laser on the appearance of data. Regarding the general 2 D marking users, even if there is no need for surface marking and other high-grade characteristics ,3 D laser marking function for multi-gray multi-color plane processing is also very meaningful.

◆ Concave and convex surface engraving

In the traditional 2D marking form, the workpiece must be placed on the same plane, and the machining surface must be on the same plane to finish the marking of a molding. By using the characteristics of 3D laser marking machine, the marking can be finished once when the workpiece has a height drop, even on the oblique slope. It can adhere to the consistency of processing, so that the processing content does not deform and does not constitute color difference. It greatly facilitates the carving of three-dimensional workpiece, reduces the process and improves the marking power.

Some Marking Samples

What is Field lens and how to choose:

Field lens, also called flat field focusing mirror, scanning lens, F-θ mirror. Mainly used to focus the light from the mirror on a plane. When buying, pay attention to the marking range, choose the right on according to own needs. Do not blindly seek a big scanning field one. Fiber laser marking machine and semiconductor marking machine wavelength is 1064 nm, the field lens of both is generally universal. Sometimes, however, if the original imported scanlab mirror is used, its field lens connection ring may not be M85*1, and the field lens is generally a M85*1 thread, this time a field lens to convert the connection ring.

The main functions of the field lens are:

1. Improve the ability of edge beam incident to detector;

2. Homogenize the non-uniform illumination on the optical surface of the detector;

3. In the same main optical system, the additional field lens will reduce the area of the detector; if the same detector area is used, the field of view can be expanded to increase the incident flux;

About format many customers want to buy a large format field mirror, because he has to consider his machine on a wide application of marking. So he may also think that the next time his product may be larger, perhaps need a larger format, for the long-term benefit. But please noted that the larger the size of the field lens, the greater the focal length and working distance of the corresponding field mirror. The longer the focal length, the larger the laser focusing spot will be. The same laser is distributed on a larger spot area, and the energy density will become smaller, which will lead to the shallow marking depth.

As we all know, the attenuation of laser energy in the air is very severe, that is, the larger the focal length of the field mirror, the greater the laser energy loss, the thicker and shallower the lines. So the size of the field lens must choose the most suitable scanning field.

NOTE: 30W or 50W laser engraver is available.
