Cold sheet metal processing technology
Time 2014- 10- 0 9
Typically of metal sheet metal processing, i.e., the cutting tool removal of excess metal layer from the metal material (blank) or the workpiece so that the workpiece to obtain a certain shape, dimensional accuracy and surface roughness of the processing methods. Such as turning, drilling, milling, planing, grinding, broaching, etc.
In metal technology, and the corresponding thermal processing, cold refers to lower than the recrystallization temperature plastic deformation of the metal processing technology, such as cold-rolled, cold-drawing, cold forging, stamping, cold extrusion. Cold deformation resistance in the metal forming, while hardening can increase the hardness and strength of the workpiece, but will make the plastic lower. Cold section of the small size suitable for processing, processing size and surface roughness higher metal parts.
