Drilling
Process limitation of general punching in press work・・・[1.3 x t]※Material: In the case of carbon steel, when a hole below the minimum thickness is necessary, it is created by drilling after the press work. Example: Grappling hole such as a spring hook
Sintering or machining process

Distance between a general hole and the outer diameter in press work: [2 x t or more]
A part that must be made from material less than 2t is produced by a sintering or machining process.

Machining process or fine blanking

In press work, some drift generally occurs. However, the sliding section, or the section that receives the surface pressure, slips locally or receives the surface pressure due to drift. Therefore, wear is a problem. Drift is eliminated by using a machining process to reduce the surface pressure.
