Deburring and Surface Finishing for Hard Materials

Deburring and finishing harder materials can be an expensive and time-consuming problem. Recently, Brush Research Manufacturing (BRM) was approached by a manufacturer of carbide wear rings that was having difficulty achieving their required surface finish. BRM recognized an application for its Diamond Flex-Hone, a new tool that's designed for cylinders ranging from 4-mm to 20-mm in diameter.

As the pictures on BRM's website show, the Diamond Flex-Hone is well-suited for the surface finishing and cross-hole deburring of harder materials such as carbide, ceramic, and space age alloys. In the case of the carbide wear rings, the Diamond Flex-Hone was used in progressively finer grits to create a near mirror finish, lowering the Ra from 0.7 to just 0.05 μm.

Choosing the Right Tools

Brush Research Manufacturing has a surface finishing laboratory for solving difficult finishing and deburring problems. Customers send in parts for evaluation, and BRM then selects the appropriate tools. After running tests, BRM recommends tools to its clients along with the operating parameters and surface finishing measurements, if required.

With the Diamond Flexhone, there are three available grit selections. Tools that are designed for cylinders other than 4-mm to 20-mm in diameter are also available.
