A type of machine tool called an Internal Grinding Machine is used to grind the inner surfaces of workpieces that are cylindrical or semi-circular. To achieve the desired level of precision and surface finish, the grinding wheel is placed inside the workpiece and rotated by the machine tool. Internal Grinding Machine can be used to achieve extremely high levels of accuracy and surface finish by grinding the interior surfaces of cylinders, cones, and other shapes. Precision parts are frequently produced using these machines in sectors like aerospace, automotive, and manufacturing. CNC technology or manual operation are both options for controlling these machines.
