The internal grinding machine
processes the interior surface of cylindrical elements. The common term internal cylindrical grinding machine further delineates the machine's function. External cylindrical grinding machines
with an interior grinding appliance are also available, allowing pieces to be worked in a single clamping operation and, for example, external bearings and the correspondent internal shaft seat to be exactly centered to one another. Both conventional and CNC internal grinders are available. Internal grinders typically have a grinding spindle with various pivoting positions.

The basic structure of the internal grinder consists of a robust main framework, designed for low vibration, which supports all the other machine
components. The spindle shaft with the main spindle propels the workpiece, which is fixed with either magnetic or conventional clamps, or a clamping sleeve. The grinding spindle propels the grinding body and swivels on a skid to adjust the material removal. Most CNC internal grinding machines possess collision control. The internal grinder operates both dry, or with appropriate cooling. Cooling eases the removal of the milling waste, improving the accuracy of the surface. The precision of this machine within hundredths of a millimeter, allowing fittings to be produced without a problem.
