Supply advanced LMJ microjet technology laser cutting equipment

Short Description:

The focused laser beam is coupled into the high-speed water jet, and the energy beam with uniform distribution of cross section energy is formed after full reflection on the inner wall of the water column. It has the characteristics of low line width, high energy density, controllable direction and real-time reduction of surface temperature of processed materials, providing excellent conditions for integrated and efficient finishing of hard and brittle materials.

Advantages of LMJ processing

The inherent defects of regular laser processing can be overcome by the smart use of laser Laser micro jet (LMJ) technology to propagate the optical characteristics of water and air. This technology allows the laser pulses fully reflected in the processed high purity water jet in an undisturbed manner to reach the machining surface as in optical fiber. From the perspective of use, the main characteristics of LMJ technology are as follows:

1.The laser beam is a columnar (parallel) structure.

2.The laser pulse is transmitted in the waterjet like optical fiber, which is protected from any environmental interference.

3.The laser beam is focused in the LMJ equipment, and there is no change in the height of the machined surface during the whole machining process, so that there is no need to continuously focus with the change of processing depth during the machining process.

4.In addition to the ablation of the work piece material happened during each laser pulses, about 99% of the time in each single unit time from the beginning of each pulse to the next pulse, the processed material is in real-time cooling of water, thus almost erasing the heat-affected zone and remelting layer, but maintaining the high efficiency of processing.

5.Keep cleaning the processed surface.
