What is the meaning of chamfer c2 in mechanical system? How to understand chamfer C2 on mechanical paper?

1. In mechanical drawing, 12 in chamfer CC2 indicates that the length of the right-angled edge of chamfer is 1mm and 2mm respectively.

2. In order to remove burrs caused by machining and facilitate the assembly of parts, chamfers are usually made at the ends of parts.

3. In addition, in the production process of polysilicon wafer in photovoltaic industry, there is a process called chamfering/polishing, where chamfering is a verb, which means the process of treating the edge of silicon ingot and removing edges and corners.

4. Chamfering is mainly to rotate the shaft and hole in the process of machining along the equal angle of 30 45 60 or to make a certain length of inclined plane with the help of drilling machine, mainly to facilitate the installation of commonly used marking methods (for example, the chamfer angle of C 1 is 45 and the length is 1mm).

5.c is the abbreviation of English chamfer, which means oblique cutting.

6.C 1 and C2 are abbreviations, and the full names are C 1*45 degrees and C2*45 degrees (so it is correct to have the same chamfering on both sides).

7. In addition, because the chamfer is usually 45 degrees, it is omitted.

8.CC2 indicates that the axial width of the dimension is 1mm and 2mm, and the angle is 45 degrees.
