HOLE HONING DEVICE Russian patent published in 1994 - IPC

FIELD: machining. SUBSTANCE: device has a body, a spring acting on abrasive rods through an unclamping cone and is mounted in a mandrel with a shank on the spindle of a numerically-controlled machine. The spindle has a mandrel clamping spring and a mandrel unclamping unit with mandrel condition control transducers: "clamped" - "unclamped". The hone has a movable link located in a mandrel axial bore, the link provides automatic rod compression and is axially spring-loaded relative to the mandrel. One end of the link is rigidly connected to the shank, and the second end is engageable with the end of the unclamping cone. The mandrel unclamping unit additionally has a rod compression control transducer. The force of the spring which acts on the movable link must be by a factor of 3-4 larger than that of the spring acting on the unclamping cone of the hone. EFFECT: improved structure. 4 dwg
