Roller Burnishing Tools

Roller Burnishing Tool is a non-cutting machining process to produce mirror-like surface finish with low surface roughness of Ra-0.05um to Ra-0.35um, consistently accurate size and increased hardness of the skin layer. It is a type of cold working process where it removes the surface undulations generated after machining on metal by compressing the peaks of a metal's surface into the valleys like "ironing".

It is used where a hole is required to be increased in size by few microns where it cannot be achieved by machining process like boring and also improve its surface finish, cylindricity and surface hardness. 

Following are types of applications for which we offer the tools- 

• Through hole
• Shaft
• Taper hole
• Surface
• Groove
• Threads

For any other application, will be manufactured against order.
