Burnishing
Burnishing is a finishing process used in manufacturing and metalworking to improve the surface finish of a workpiece and, in some cases, to harden the surface. This process involves the use of a hard, non-abrasive tool to smooth the rough surface of a metallic object. The primary goal of burnishing is to achieve a high level of surface finish, reducing surface roughness by plastic deformation of the surface layers of the material.
Process[edit | edit source]
The burnishing process can be performed using a variety of tools, such as balls, rollers, or specially designed burnishing tools. These tools apply a significant amount of pressure to the workpiece's surface, causing a plastic flow of the material. Unlike abrasive processes, which remove material from the workpiece, burnishing smooths out the peaks and valleys on the surface without removing any material. This action fills in the surface imperfections and improves the surface finish.
There are several types of burnishing, including:
- Roller burnishing, where cylindrical rollers are pressed against the workpiece.
- Ball burnishing, using spherical balls to apply pressure.
- Diamond burnishing, which employs a diamond-tipped tool for harder materials.
Applications[edit | edit source]
Burnishing is widely used in various industries for different purposes:
- In the automotive industry, to improve the fatigue life of components.
- In the aerospace industry, for enhancing the surface finish of aircraft parts.
- In machining and toolmaking, to achieve a mirror-like finish on tools and dies.
Advantages[edit | edit source]
- Improved surface finish, which can reduce friction and wear.
- Increased hardness on the surface layer, enhancing the fatigue strength and corrosion resistance.
- No removal of material, which can be beneficial for maintaining dimensional accuracy.
Disadvantages[edit | edit source]
- Limited to materials that are ductile enough to undergo plastic deformation.
- Requires specialized equipment and tools, which can be an added cost.
