Roller burnishing is a surface finishing technique where hardened rollers cold work surface imperfections to reduce surface roughness. Roller burnishing differs from abrasive surface finishing techniques in that material is displaced rather than removed.

2017年9月1日 · What is Roller Burnishing? This process enables fast and repeatable finishing of metal surfaces to mirror-like quality, but without removing any metal. How do you finish the surface of a metal part to a mirror-like sheen without putting it …

Mollart roller burnishing equipment provides chipless machining and cold working of surfaces to create high specification surface finishes, eliminating the grinding process. Internal & external multi-roll tools along with carbide roll tools for ID and OD profiling of parts on CNC machines.

Roller burnishing, as the name suggests, employs a tool with single or multiple rollers. For multiple rollers tools, the rollers are present around the circumference of a supporting shank. The figure shows the schematic of a burnishing operation with a single roller burnishing tool.

2024年3月13日 · Roller burnishing enhances the surface finish and dimensional accuracy of cylindrical workpieces through a unique process that compresses rather than removes material. This technique involves the use of a hardened, highly polished roller tool that is pressed against the rotating workpiece.

Roller burnishing is a highly productive process in which roughness can be reduced by 50 - 95% compared to pre-machining, depending on the material. A surface quality below Rz = 1µm can easily be achieved with non-hardened steels or aluminium …

What is Roller Burnishing? Roller burnishing is a surface-finish-ing technique in which hardened, highly polished steel rollers are brought into pressure-contact with a softer work-piece. The tool incorporates a planetary system of tapered rolls that are evenly spaced by a retaining cage. When the tool engages the workpiece, a hardened

Roller burnishing is a non-cutting process for smoothing and strengthening (metallic) workpieces by means of rolling elements. During roller burnishing, one or more rollers are subjected to a force directed vertically to the running surface (rolling force).

Almost all processes for the manufacturing of high-quality surfaces can be replaced by roller burnishing (e.g. fine turning, grinding (superfinishing, lapgrinding, etc.), galling, honing, polishing, rubbing). This proven process entails considerable technological and economic advantages for surfaces in the roughness area R z < 10 µm.
