The regulating wheel determines the workpiece's rotational speed. Tilt it a few degrees and the workpiece will be pulled through the wheels and out the back of the machine, a technique known as through-feed grinding. Infeed grinding is the second technology available for centerless grinding.

There are three main types of centerless grinding: through-feed, in-feed and end-feed grinding. For through-feed grinding, the grinding wheel is canted with respect to the other two axes so that a horizontal feed of the workpiece is achieved. This auto feeding characteristic is useful for rapidly processing many parts in quick sequence.

According to the configuration of grinding wheel shaft, internal grinding machine has horizontal and vertical points. ① ordinary. The table is clamped by the chuck mounted on the spindle of the headstock for circular feed motion. The worktable drives the grinding wheel frame to reciprocate along the bed guide rail (see machine guide rail).

Through–feed centerless grinding is completely feeding the workpiece to the grinding wheels. This doesn't require a separate speed mechanism, making it very efficient yet it can only be used for cylindrical–shaped parts. The wheel cannot be dressed to create more complex shapes since this only imparts a horizontal velocity to the workpiece.
