Explanation

Forming processing carried out in the temperature range near room temperature. Generally, it can be divided into mechanical cutting and cold deformation processing. Mechanical cutting processing includes machining methods such as turning, milling, planing, grinding, drilling, and boring. Cold deformation processing includes cold rolling, cold extrusion, cold forging, cold bending, cold pier, cold drawing, etc. Cold deformation processing does not require heating of the workpiece, and the product has high dimensional accuracy and good surface quality, generally without the need for subsequent mechanical processing. However, during cold deformation processing, there is a high resistance to deformation and a high requirement for equipment capacity; In addition, metal or alloy will undergo deformation strengthening during cold deformation. Intermediate annealing is required for large deformation.
