Vertical cone polisher: This machine uses a covered cone within a perforated screen to create an abrasive surface for polishing rice. [ 7 ] Horizontal polisher : This machine uses a cylinder covered in emery that is placed within another cylinder and rotated to polish the rice.
A no. 8 ("mirror") finish requires polishing and buffing compounds, and polishing wheels attached to high speed polishing machines or electric drills. Lubricants like wax and kerosene [ 4 ] may be used as lubricating and cooling media during these operations, although some polishing materials are specifically designed to be used "dry."
Chemical mechanical polishing (CMP) (also called chemical mechanical planarization) is a process of smoothing surfaces with the combination of chemical and mechanical forces. It can be thought of as a hybrid of chemical etching and free abrasive polishing. [ 1 ]
Laser polishing, also referred to as laser re-melting, is a type of micro-melting process employed for improving surface quality of materials.As opposed to other conventional polishing processes, this process does not involve removal of materials from the workpiece surface.

Electropolishing, also known as electrochemical polishing, anodic polishing, or electrolytic polishing (especially in the metallography field), is an electrochemical process that removes material from a metallic workpiece, reducing the surface roughness by levelling micro-peaks and valleys, improving the surface finish.

Flame polishing, also known as fire polishing, is a method of polishing a material, usually glass or thermoplastics, by exposing it to a flame or heat. [1] When the surface of the material briefly melts, surface tension smooths the surface. Operator skill is critical with this method.
