For metal parts processing, the more common surface treatment methods are mechanical grinding, chemical treatment, surface heat treatment, spraying surface, etc
Application: cylindrical surface, conical surface, plane and other simple shape parts
Surface bulging (extruding or extruding)
Surface blotting is to squeeze a steel ball or other shape blotting tool with a diameter slightly larger than the hole diameter through the machined inner hole of the workpiece at room temperature to obtain an accurate, smooth and strengthened surface.
1、 Surface deformation strengthening
Surface deformation strengthening
Surface deformation strengthening refers to the surface strengthening process which makes the steel parts plastic deformation at room temperature to improve the surface hardness and produce favorable residual compressive stress distribution.Shot peening
Shot peening is a kind of strengthening technology that a large number of high-speed moving projectiles are sprayed on the surface of parts, just like innumerable small hammers hammering the metal surface, causing certain plastic deformation on the surface and subsurface of parts.Rolling treatment
The free rotating quenched steel roller is used to roll the machined surface of the steel parts to produce plastic deformation, flatten the rough convex peaks on the surface of the steel parts and form favorable residual compressive stress, so as to improve the wear resistance and fatigue resistance of the parts.Application: cylindrical surface, conical surface, plane and other simple shape parts
Surface bulging (extruding or extruding)
Surface blotting is to squeeze a steel ball or other shape blotting tool with a diameter slightly larger than the hole diameter through the machined inner hole of the workpiece at room temperature to obtain an accurate, smooth and strengthened surface.
