· Table 2 provides general practical guidelines for classifiion of electrical areas where combustible and/or flammable materials are loed and processes are performed in a coal .
Inside diameter grinding, also called as internal grinding, is used for grinding the inner diameter of tubular object. 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.
