A machine tool is a machine for shaping or machining metal or other rigid materials, usually by cutting, boring, grinding, shearing, or other forms of deformation.Honing is an abrasive machining process that produces a precision surface on a metal workpiece by scrubbing an abrasive stone against it along a controlled path. Honing is primarily used to improve the geometric form of a surface, but may also improve the surface texture.
Typical applications are the finishing of cylinders for internal combustion engines, air bearing spindles and gears. There are many types of hones but all consist of one or more abrasive stones that are held under pressure against the surface they are working on.

*OD through-feed honing (taper and straight)
* Bore honing
The main task of the coolant is to aid in the dissipation of heat from removed stock. It also reduces the friction between the abrasive and the workpiece. Therefore, proper wetting, adhesion, pressure, temperature resistance, and corrosion protection are all factors when selecting a coolant. Oil (mineral or diester based) is used as the preferred cooling and flushing media. Water emulsions may also be used.
Due to the tension-free reception of loose parts in the carriers, virtually any solid material can be processed. The application range is very wide, from a soft to a very hard material (thermoplastic plastic to sapphire or ceramic).
Examples are vane pump parts made of PPS, ceramic insert made of SiNi, watch windows, LED wafer in sapphire, bearing rings, vane pumps, gear steel, cutting knives and carbide.
The surface is similar to the typical honing crosshatch, this leads to good tribological properties and fine roughness. The low sub surface damage will have a positive impact on subsequent polishing processes
