Laser cutting burr, folds, high accuracy, superior to plasma cutting. For many mechanical and electrical manufacturing industry, due to the speed of the computer program of modern laser cutting system to facilitate the cutting of different shapes and sizes of the workpiece (workpiece drawings can also be modified), it is more often than punching, molding process is preferred; despite its processing slower than the red mode, but it does not mold consumption, no need to repair the mold, and also saving to replace the mold time, thus saving processing costs, reduce product cost, so the whole economically more cost-effective. The expert group ofgreen laser pointerholds the high hope for the market value ofgreen laser pointer.
On the other hand, from the perspective of how to make the mold to adapt to changes in the size and shape of the workpiece design, laser cutting can also play its precise, reproducible advantage. Cascading priority mold manufacturing means eliminating the need for advanced mold making work, laser cutting operating costs are not expensive, and therefore can significantly reduce mold manufacturing costs. Also bring additional benefits of laser cutting mold is mold trimming will produce a shallow hardened layer (heat affected zone), improve the wear resistance of mold running. Non-contact laser cutting features to circular saw blades, cut to shape to bring the advantages of non-stress, thus increasing service life. Daily maintenance ofgreen laser pointeris of much importance.
Laser cutting of common engineering materials. Laser cutting of metal materials. Although almost all metallic materials at room temperature infrared wave energy has a high reflectivity, but the emission in the far-infrared band 1.064um beam of the lamp-pumped ND: of YAG laser and laser 10.6μmCO2 is successfully applied to many metal laser cutting practice. Laser cutting of nonmetallic materials. 10.6μm wavelength of CO2 laser beam is easy to be non-metallic material absorption, thermal conductivity and low evaporation temperature and the absorption of the beam inside the material of almost the entire input and instantaneous vaporization at the spot irradiation, the formation of the starting hole, into the cutting The process of a virtuous circle. The green laser pointer system should be well managed.
Laser cutting technology. The laser cutting is the world's advanced cutting process. Its biggest advantage is the small laser spot, is to focus on, so the cut kerf is small, no dross, almost no heat distortion, the cutting surface finish. Laser cutting is the key to the laser source. Cutting thickness size, cutting the quality of the merits of cutting stability and so depends on the performance of the laser source. Common CO2 laser source is the electric field or high frequency oscillation to force the gas mixture sealed in a container in the excited state, and generated by the Stimulated Emission of Radiation monochromatic light, such optical radiation back and forth between the mirror and the reflection and transmission mirror reflection, accumulate to a sufficient energy injection by the output lens. Far this laser source electrode distance from the workpiece and the electrode is loaded into the laser beam. Electrode and easy burning, carrier gas consumption, the laser wavelength interference. The workshop plans to build a new production line of green laser pointer.
High voltage (about 10 ~ 25kV) formed on the operation of insecurity. The laser source larger, more complex maintenance. Consumption of wearing parts. Advanced mixed gas laser with a high-frequency resonant excitation source, the laser source electrode from the workpiece near the electrode mounted on the outside of the laser beam. Compared with the common CO2 laser source electrode almost does not burn. Carrier gas consumption. The laser wavelength without interference. Low voltage (about l ~ 1.2kV), the operation is very safe. Laser small size, simple to maintain. Laser cutting speed, high precision, must be computer-controlled high-speed cutter to match. The appearance inspection ofgreen laser pointershould be performed.
