Surface finish significantly affects the performance, durability, and quality of manufactured parts. A smoother finish reduces friction and wear, enhancing the part's longevity. Burnishing, a process that compresses the part's surface, is a common technique to improve surface finish. However, it's effectiveness relies on the material's ductility.

While there are many variables that can impact the surface finish of a part, the 3 key variables, time, pressure, and pre-finish, all play a critical role in the ultimate outcome of the part. Changing any one of these variables could result in dramatically different results, which is why it’s important to understand what they are and how they work together to achieve the desired surface finish.

Roller burnishing is a quick and effective method for achieving smooth surface finishes on metal work pieces. With a variety of burnishing tools on the market, it can be challenging to determine which will work best for a specific application.

Electric motors are used in a wide variety of applications, from lawn tools to automobiles. When looking at laminated motors, tight manufacturing tolerances are ideal for producing higher efficiency products. Roller burnishing can be used to set the air gap in lamination stacks and eliminate the need for grinding and honing.

While traditional finishing methods are effective, in many cases, these processes require multiple operations and set-ups to achieve the desired finish. Burnishing is an effective and efficient alternative that often eliminates the need for secondary processes entirely.
