This paper proposes a roller burnishing method that controls the sliding direction of the burnishing tool on the surface of cylindrical workpiece. In this study, the sliding direction was set by inclining the axis of the burnishing tool with respect to the axis of the workpiece and by actively rotating the roller of the burnishing tool. The workpiece was a cylindrical aluminum …
It is mainly used for the compound process of boring and roller burnishing for hydraulic cylinder parts. The hole tolerance is up to IT7-8, the surface roughness is up to Ra 0.2-0.4 µm. Its processing efficiency is 10 times of the traditional boring technology and 20 times of ordinary honing machines.
Roller burnishing is a surface finishing technique in which hardened, highly polished steel rollers are brought into pressure contact with a softer piece part. As the pressure generated through the rollers exceeds the yield point of the piece-part material, the surface is plastically deformed by cold flowing of sub-surface material.
- Hard roller - Shank - High stiffness spring To improve its hardness heat treated shank is made of mild steel. The shank of roller burnishing tool has square cross section (30mm * 30mm) which is hold in the tool holder. Using a bolt and nut assembly is use provision to fix the roller at the end of the square shank which looks similar to a fork.

Burnishing is a chipless machining method which cold works the metal without cutting or abrading the surface. It removes no metal but rather compresses, or "irons-out" the peaks of a metal surface into the valleys, generating a dense and uniform surface. Roller burnishing improves surface finish and results in dimensional accuracy.
Roller burnishing is a cold-working process that produces a fine surface finish. The planetary rotation of the hardened rolls creates pressure over a metal surface. Unlike cold rolling, which produces large sectional changes, roller burnishing involves cold-working on the surface of the workpiece to improve the surface structure.

Burnishing tool Roller burnishing is a surface finishing technique in which hardened; highly polished steel rollers are brought into pressure contact with a softer piece part. Burnishing processes are used in manufacturing to improve the size, shape, surface finish, or surface hardness of a workpiece. A 20 mm diameter hardened roller of 5 mm
Roller burnishing is a process which used in the present experimental work of on specially fabricated Aluminium 6061.The surface integrity places a vital role in determining the strength and fatigue properties of the material.In the process, a roller of suitable strength is made to impinge on the cylinder which is fixed to the lathe. The movement of the tool is coaxial with …

An electric burnisher is a high-speed machine that spins at 1000-3000 RPMs. These units are used for polishing your hard floors. … Floor burnishers come in a variety of different sizes like buffers, but they also come in different power options.
Roughness: An initial 80- to 120-microinch (2- to 3-micron) surface is ideal for roller burnishing. The rougher starting finish allows for a more dramatic change in the final finish because the rollers can apply greater pressure to more of the surface.
In this paper, experimental studies are performed to investigate the influence of roller burnishing parameters (i.e., spindle speed, burnishing depth, and burnishing feed) on …
In roller burnishing, a hard roller is pressed against a rotating cylindrical workpiece and parallel to the axis of the workpiece. Burnishing is a cold forming process, in which the material near a machined surface is displaced from peaks to fill the valleys of the surface profile. Roller burnishing is an
Skiving and Roller Burnishing Systems are used to: Improve surface finish—as fine as .10 – .15 microns (4 to 6 micro-inches) RA on average Improve size control—tolerances within 0.0254 mm (.001 inch) on average
What is the purpose of burnishing? Burnishing aims to reduce the roughness average (Ra) of the piece, hardening the surface and producing an impressive, mirror-like finish. In the burnishing process, the workpiece is brought into contact with one or more rotating steel rollers (roller burnishing) or balls (ball burnishing).

Burnishing process on standard lathe (manual). Pictures of surface roughness and finish are shown at the end.
Roller burnishing is applied if metal components with high or pre-defined surface quality are requested, or the desired quality can not be achieved in a reliable manner by machining. When the need is for increasing the operational stability of a metal material or realizing solutions for lightweight-construction, deep rolling is applicable.
Rotary power source 16 is energized to rotate the workpiece l2 relative to the burnishing tool which is held stationary by clamping device 14. As can be seen in MG. 3, rotation of the workpiece will cause the rollers to rotate in one direction which, in turn, will cause the mandrel to freewheel in the opposite direction since roller cage 40 is ...
Burnishing Process. Burnishing is a surface modification process that produces a very smooth surface finish by the planetary rotation of a tool over a bored or turned surface.
