Abstract

1390544 Boring tools; vibration damping TIEFBOHR-TECHNIK GmbH & CO 9 Aug 1972 [25 Aug 1971] 37138/72 Headings B3B and B3C [Also in Division F2] In a deep boring tool, the tool is mounted and guided by its shank for limited rotation in the spindle and is connected thereto through a resilient coupling which may itself have a vibration damping characteristic, or may be provided with vibration damping means. As shown in Figs. 3 and 4, an extension 20 of a two-part housing 16 is connected to a spindle, not shown, the drive to the boring tool 2 being transmitted through the housing 16 and a flexible coupling including resilient members 4 housed within a part 17 of the housing 16 and a two-armed lever 28 connected through a sleeve 22 and nut 26 to the tool 2. Vibration damping is afforded by an eddy current brake acting between the housing 16 and the sleeve 22. In modifications, not shown, the drive between the spindle and the tool is transmitted by elastomeric members which provide both resilience and vibration damping effect. The tool and spindle may be driven and the work stationary or vice-versa and cooling fluid may be passed down passage 6 into the hollow shank of the tool 2.
