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.
