The workshop needs the material acquisition sheet to get laser pointer .
In addition, the workpiece clamping device to ensure the cutting quality is also crucial, because the laser cutting process, the heat and stress release throughout the workpiece, this must be considered to adapt to the fixed workpiece in order to avoid causing the workpiece move , affecting the accuracy of cutting size of the workpiece. Laborers laser Fali Lai laser cutting machine cutting speed on cutting quality. Comply with an empirical formula for a given laser power density and the material, cutting speed, as long as more than the pass threshold, the material of the cutting speed and laser power density proportional to the increase in power density can increase the cutting speed. The power density referred to here is not only related with the laser output power, beam quality mode. The performance of laser pointer might be influenced.
So tightly acetone bottle, do not be left after the cleaning Acetone fell back a new bottle of acetone. Cleaning of the reflector lens: the lens is removed from the frame; mirror up, lens paper placed on the mirror; lens paper a few drops of acetone, and gently pull the lens paper stitch mirror; repeated the above process, until the mirror clean dirt and stains stay in the mirror; then the lens into the mirror base. If the molybdenum mirror, mirror, because it can not plating, polishing can be used directly, so it can be water (soapy water or water containing a detergent) to clean the mirror. Other surface coating of the lens can not be washed with water, because a lot of coating is dissolved in water, the lens will be destroyed.  Under normal circumstances, material cutting require the use of auxiliary gas, the problem involves the auxiliary gas type and pressure. Typically, the auxiliary gas with the laser beam emitted to protect the lens from pollution and blow away the slag of the bottom of the cutting area. Clear melting and evaporation materials, non-metallic materials and some metal materials, the use of compressed air or inert gas, while suppressing the excessive burning of the cutting area. Most metal laser cutting using reactive gas (O2), the formation of oxidation exothermic reaction occurred with the hot metal. The selection process of laser pointer should be normalized.Will not be able to grasp the boiler thermal efficiency of coal and other indicators, but also unable to provide for the hospital the next year's coal procurement valid data. In recent years, countries and groups of companies energy conservation, energy control and measurement has high demands, we urgently aware of the need to restore the measurement of boiler coal. Multi-party research, we purchased in October 2008, JG-500 laser belt scale developed by the Department of Physics, Albert Chen Safety Technology Co., Ltd. production, online coal-fired the furnace metering system for accurate measurement of each coal-fired boiler. Introduction of the laser belt weigher.
