Based on the characteristics of the mechanical manufacturing industry, most workpieces are divided into three levels. For example, precision machinery such as medical machinery, clock machinery, and instruments have a majority of thin plates with a thickness of less than 3MM, while for some agricultural machinery, there are more medium thick plates with a thickness of 6-8mm. There are also a small number of mining machinery or lifting machinery accessories, with thicknesses ranging from 10-16mm. 3000W-30000W fiber laser can be selected according to production and efficiency requirements.
