Honing and rolling are two common precision machining methods applied in the mechanical manufacturing industry to improve the surface quality and dimensional accuracy of parts.
Honing is a method of precision machining of holes or other machined surfaces using an oilstone (also known as a honing bar), and is a special form of grinding.
During honing, the oilstone is installed on the honing head, and the expanding mechanism expands the oilstone radially to press it against the surface of the workpiece. The honing head rotates under the drive of the machine tool spindle and performs reciprocating linear motion, or the workpiece performs reciprocating linear motion, to achieve honing processing of the workpiece.
Rolling is a method that utilizes the cold plasticity characteristics of metals at room temperature to apply pressure to the surface of the workpiece through rolling tools, causing plastic flow of the metal on the surface of the workpiece and achieving the purpose of finishing.
When rolling, rolling tools (such as ball bearings, cylindrical rollers, conical rollers, etc.) roll on the surface of the workpiece, applying pressure to the surface of the workpiece, causing plastic deformation of the metal on the surface of the workpiece, filling in the small bumps and depressions on the surface, and improving the surface smoothness.
