随着工业化的提升，用户对钣金加工零件的工艺要求也越来越高。这就催生了钣金加工装备现代化的整体提高，CO2激光切割技术因蕴而生。激光切割机以其加工零件的精度高、加工周期短、加工中无需进行传统冲压加工对模具的更换，就可以加工任意复杂零件等优点，在钣金零件方面成为了大幅提高劳动生产率的新兴装备，从而被越来越多的制造企业采用。本公司自从1998年引进第一套德国通快的TRUMPF-L2530激光切割机，2001年引进第二套TRUMPF-L3030激光切割机后，对于钣金零件的加工起到了革命性的作用，特别是在有复杂外型和高材料厚度的零件的加工方面，由于采用了激光切割加工方式，大大提高了零件加工精度，同时缩短了生产周期，提高了劳动生产率。随着激光切割机的应用不断增多，其加工原理和相关的工艺问题也就成为了大家越来越渴望了解的技术问题，本文就常用CO2激光切割技术的原理以及它在生产中所遇到的一些工艺问题做了一些探讨，希望对大家的工作起到一点帮助。

With the industrialization of the upgrade, users of sheet metal parts processing technology are increasingly high requirements. This appearance of sheet metal processing equipment modernization of the overall enhancement of CO2 laser cutting technology for Yun Hang. Laser cutting machine with the processing of high precision parts, processing cycle short. Processing without traditional stamping die processing of the change, we can arbitrarily complex processing components, and other advantages, in the sheet metal parts become a substantial increase in the labor productivity of new equipment, thereby creating more and more enterprises to apply. Since 1998 the company introduced the first German Link Express TRUMPF-L2530 laser cutting machine, 2001 introduction of the second TRUMPF-L3030 laser cutting machine, For sheet metal parts processing played a revolutionary role especially in a complex appearance and high material thickness of the parts processing, the use of laser cutting, greatly increased the precision machining parts, and shorten the production cycle, improved labor productivity. With laser cutting machine of increasing processing principles and related technical problems, it has become increasingly anxious that we understand the technical issues, This paper used CO2 laser cutting technology and its principles in production encountered some problems doing some research into , we hope to play a little help to work.

随着工业化的提升，用户对钣金加工零件的工艺要求也越来越高。这就催生了钣金加工装备现代化的整体提高，CO2激光切割技术因蕴而生。
as the industrilization updates, the process requirements for machining parts using sheetmetal are increasing more and more which make the integral advance of modernizing the sheetmetal fabrication facilities, thus CO2 laser cutting technology is born.

激光切割机以其加工零件的精度高、加工周期短、加工中无需进行传统冲压加工对模具的更换，就可以加工任意复杂零件等优点，在钣金零件方面成为了大幅提高劳动生产率的新兴装备，从而被越来越多的制造企业采用。
laser cutter has a lot of advantages such as high maching acuracy, short production cycle, no replacement of tool ot process complicate parts in any shape which is needed for traditional punch work during operation, further becomes the rising equipment for enhancing labor production rate in the sheetmetal component field, thus is used by more and more manufacturers.
