COMBINATION METHOD FOR PLAIN NEEDLE GRINDING Russian patent published in 2005 - IPC

FIELD: machine engineering, possibly manufacture of tools for mechanical working, namely cutting metals, removing slag, corrosion products, scale of rolling process, burrs in milling, multi-position and multi-operation machine tools.

SUBSTANCE: method is realized with use of tool having built-up grinding disc and face milling needle. Tool is subjected to rotation and feed motion along ground surface; blank is driven to reciprocation motion. Disc and milling needle are mounted on coaxial rotating separately in different directions hollow and central shafts. Disc includes abrasive-diamond annular segments secured to metallic plates, tore-shaped hollow elastic envelope secured to boss and ring.

EFFECT: enlarged manufacturing possibilities, enhanced efficiency and quality of grinding, restoration of initial position of grinding disc face relative to cutting end of milling needle, possibility of burning-free intermittent grinding.
