The Reason and Processing Method of Fiber Laser Cutting Machine Processing Burned Edge?

Apr. 25, 2020

In today's industrial manufacturing field, laser cutting machine equipment has a wide range of applications in all walks of life due to its efficient and flexible processing advantages, especially in the metal processing manufacturing industry. Fiber Laser Cutting Machine has become almost a must for all processing manufacturers Sharp weapon. However, laser processing equipment occasionally encounters some problems during the operation. The following Fabric Laser Cutting Machine Factory will lead you to understand it together.

Laser cutting machine equipment processing sheet metal parts produce scorching and slag hanging reasons:

Laser cutting will produce a lot of heat when processing sheet metal parts. Under normal circumstances, the heat generated by cutting will diffuse into the processed sheet metal along the slit to be fully cooled.

Especially in the processing of small holes in the metal laser cutting machine, the outside of the hole can be sufficiently cooled, but the small hole part inside the single hole has a small space for heat diffusion, and the heat energy is too concentrated, causing overburning, slagging, etc. In addition, in the cutting of thick plates, the accumulation of molten metal and heat accumulated on the surface of the material during the perforation will cause the auxiliary air flow to be turbulent and the heat input is too much, thereby causing overburning.

How to solve the problem of burning and slag hanging?

Solution for overburning when laser cutting small holes in carbon steel: In carbon steel cutting with oxygen as auxiliary gas, the key to solving the problem is how to suppress the generation of heat of oxidation reaction, auxiliary oxygen can be used during perforation, and then switch to auxiliary The method of cutting with air or nitrogen.

Low frequency, high peak output power pulse cutting conditions have the characteristics of reducing heat output, which helps to optimize the cutting conditions. Setting the conditions to a single pulse laser beam, high peak output with high energy intensity, and low frequency conditions can effectively reduce the accumulation of molten metal on the surface of the material during the piercing process and effectively suppress the heat output.

When laser cutting machine equipment is processing sheet metal parts, the causes and solutions of the problem of scorching and slag hanging are believed to be.
