Abstract

A feeding device, especially for a honing tool, in which a frame is formed with a cylinder having a piston mounted therein and to which is connected a spindle or feed rod having the tools mounted thereon. The piston will effect rapid advance and retraction of the feed rod while the connection of the piston to the feed rod embodies threaded means which can be adjusted incrementally or manually to effect fine feeding movement of the tools following the rapid advance thereof. Automatic control means are provided for controlling the incremental feeding of the tools and for compensating for tool wear.
