Carbide Burnishing Tools for Surface Finishing

Introduction

Burnishing is a cold working process that improves surface finish and hardness. Tungsten carbide burnishing tools provide long life and consistent results.

How Burnishing Works

A hard carbide roller or ball presses against the workpiece surface, plastically smoothing roughness peaks. This produces a mirror-like finish and work-hardens the surface.

Benefits

Burnishing improves surface finish to Ra 0.1 or better, increases surface hardness, and improves fatigue resistance. It replaces grinding or polishing in many applications.

Carbide Burnishing Tools

Carbide rollers and balls maintain their shape and surface finish through thousands of parts. They do not deform or wear like steel burnishing tools, ensuring consistent results.

Applications

Burnishing is used for shafts, bores, cylindrical parts, and bearing surfaces. It is common in automotive, hydraulic, and precision machinery manufacturing.

Conclusion

Carbide burnishing tools provide efficient, consistent surface finishing. They improve part quality while reducing machining time and cost.
