CNC Internal Grinder

CNC Internal Grinding Machine is a computer numerical control (CNC) grinding machine specifically designed for finishing the internal surfaces of part bores.  

Unlike CNC external cylindrical grinders, which process the outer surfaces of parts, CNC internal cylindrical grinders use very small grinding wheels that must be inserted into pre-machined bores within the workpiece to perform high-precision grinding of the bore walls.
