Laser cutting process parameters

by:J&D WATER     2020-03-28
Main process parameters for cutting laser cutting speed for a given laser power density and material, the cutting speed in accordance with an empirical formula, just above the threshold, material cutting speed is proportional to the laser power, the increasing power density, the cutting speed can be improved. Cutting speed with the same cutting material is inversely proportional to density and thickness. Can improve the cutting speed operations include: l increase power ( 500 - 2000 w) L change the beam pattern reduce focus spot size l ( If use short focal length lens) Other variable to hold the same process for metal materials, laser cutting speed can have a relatively adjusting range remained satisfactory cutting quality, and the adjusting range is wider than the original when cutting thin metal. Laser beam focus position after focusing spot size and lens is proportional. After short focal length lens to focus the light beam spot size is small, the focus in high power density, the material cutting is strong; But it is bad outside the focal depth is very short, adjust the margin is very small, is generally applicable to the high speed cutting BoCai. For thick workpiece, due to the long telephoto lens has a wide depth of focus, as long as have the enough power density, used for cutting is suitable for it. Due to the focus in the high power density, in most cases, the cutting, the focus position just at the surface, or slightly below the surface. To ensure focus and workpiece position relatively constant is important condition to obtain the stable cutting quality, sometimes lenses work because of poor cooling and heat causing focal length changes, it's need to adjust the focus position. Auxiliary auxiliary gas and laser beam coaxial spray, protect the lens from pollution and blow away the cutting area at the bottom of the slag, the non-metallic and part of metal materials, the use of compressed air or inert gases, melting and evaporation materials, and curb excessive burning cutting area. Assist gas pressure most metal laser cutting is the use of reactive gas ( Oxygen) Formation and hot metal oxidation, exothermic reaction, this part of the additional heat 1/3 to 1/2 can improve the cutting speed. When high-speed cutting thin plate, need higher gas pressure to prevent incision with slag on the back, when the thickness of the material or slower cutting speed, gas pressure can reduce accordingly. Laser output power laser power, size and pattern will be important for cutting happened influence, the actual operation, often set maximum power to achieve high cutting speed or for cutting thick materials. CNC laser cutting equipment recommendation: preferential deals offer 4007001618 【 Metal laser cutting equipment 】 It is mainly used for cutting stainless steel, carbon steel, aluminum, copper, aluminum, iron, gold, silver etc. Thickness is 1. 0 ~ 25 mm plate; 【 Stainless steel laser cutting equipment 】 Classic gantry double drive structure of stable and reliable, automatic switching table, at the same time of cutting up and down on another table, convenient and quick to save time; 【 Optical fiber laser cutting 】 With high-speed movement speed, acceleration and dynamic performance, is laser for efficient and specialized research and development of a product, its cutting 0.
