Burnishing is the plastic deformation of a surface due to sliding contact with another object. Visually, burnishing smoothens the texture of a rough surface and makes it shinier. Burnishing may occur on any sliding surface if the contact stress locally exceeds the yield strength of the material.

Abstract- Burnishing is a cold-working process in which plasticdeformation occurs by applying a pressure through a very hard and smooth ball or roller on a metallic surface.
CNC Machining Definition. CNC (Computer Numerical Control) Machining is a manufacturing process by which machine tools are operated under the control of a computer program that has been encoded to move the tools to generate a precisely machined part whose dimensions match the encoded program (called a G-code).
Graphite powder can be produced in several ways: graphite is relatively soft (Mosh 1–2), therefore graphite powder could be made without difficulty by rubbing a graphite lump against a sandstone grinding stone or rubbing graphite lumps together .

Graphite and carbon are generally machined dry without using Cutting fluids (coolants).If coolants are used in some machining operations (grinding, honing, polishing) the workpiece should be dried at 300-400°F (150-200°C) to remove liquids absorbed by the material.
The main goal of roller burnishing is to achieve high-quality smooth surfaces or surfaces with pre-defined surface finish. One or more rollers or balls plastify and deform the workpiece's surface layer.
Just as with milling and cutting operations, the speed at which abrasives operate has a major effect on the quality of finish, the ability to control the finishing process and on the lifetime of the abrasives.

Concrete Polishing is the process of grinding the surface layer of a hard cement surface using heavy, specialized polishing machinery to achieve a super durable, cost effective decorative floor.
Graphite powder (Fig. 1.5) can be produced in during which graphite should have worked as a burnishing tool, several ways: graphite is relatively soft (Mosh 1e2), therefore however, burnishing with graphite lumps turned out to be a graphite powder could be made without difﬁculty by rubbing a disadvantageous practice.

Superfinishing, also known as micromachining, microfinishing, and short-stroke honing, is a metalworking process that improves surface finish and workpiece geometry. This is achieved by removing just the thin amorphous surface layer left by the last process with an abrasive stone or tape; this layer is usually about 1 μm in magnitude.
