Workpiece or object will have already drilled hole and internal grinding process will be performed to finish the inner surface of workpiece with the help of small grinding wheel rotating at higher revolution per minute.
While grinding as a method of metal removal will likely take place as an earlier step in the fabrication process, this type of finishing is much more likely to come near the end. The great strength of metal grinding is that it offers the gift of precision.
Steel grinding is a process that moves a grinding wheel or segment in a plane while the wheel contacts the work piece and removes material to create a flat surface. Parts may require surface grinding for several reasons, including: Flat surfaces are required;
Grinding process control balances these three interactions to achieve the desired parameters. These interactions feed into three major commercial grinding processes: rough grinding, precision grinding and ultra-precision grinding. Rough grinding maximizes the metal removed at the cost of surface finish.
Grinding can also be considered as a machining process, i.e. process of removing metal, but comparatively in smaller volume. To grind means 'to abrade', to wear away by 'friction' or 'to sharpen'. In grinding, the material is removed by means of a rotating abrasive wheel.
Metal polishing can be done either manually or via automatic robotic metal polishing. The process that reduces surface roughness also increases a metal's luster as reflected light is scattered less from smoother surfaces. Thus, these same methods are often employed simply for improving surface aesthetics. Grinding
