Bending sheet metal fabricator

Milling: Milling is where the equipment sheet metal fabricator has to use a boring tool to do further machining on the holes that have been drilled out, cast or forged out. It can be carried out on ? CNC lathe, milling machine or CNC lathe to carry out. Milling is one of the common ways of hole machining and can be classified as rough boring, semi-finishing boring and finishing boring. The dimensional tolerance level of rough boring is IT13~IT12 and the surface roughness value Ra12.5~6.3μm; the dimensional tolerance level of semi-finish boring is IT10~IT9 and the surface roughness value Ra6.3~3.2μm; the dimensional tolerance level of finish boring is IT8~IT7 and the surface roughness value Ra1.6~0.8μm. many people are interested in "What are the ways and advantages of CNC machine sheet metal processing? How is the cost of sheet metal processing calculated" is not very good to grasp, so we will introduce some basic general knowledge of CNC sheet metal processing for the big guys.
