CHUCK WITH RADIAL DISPLACEMENT OF CUTTER TIP Russian patent published in 2014 - IPC B23B29/34 

FIELD: process engineering.

SUBSTANCE: this chuck comprises cylindrical case accommodating the holder and holder fastener arranged to displace radially relative to the case lengthwise axis and stop to position said chuck relative to machined part. To up precision of reliability of bore machining at cutting grooves, holder clamp is composed of the shaft and cylindrical sleeve aligned inside said case. Note here that said sleeve is locked inside the case at the stop location area while the shaft has inclined groove made at its lengthwise axis. Said holder is composed of L-like wedge element arranged displace in said shaft inclined groove and having its end locked at cylindrical sleeve central zone. Note here that cylindrical sleeve, shaft and holder are fitted to interact with each other so that at shaft lengthwise displacement towards holder stop can displace radially while at back displacement said holder is locked by wedge.

EFFECT: higher precision and reliability.
