Fine boring tool for the final machining of a precision bores

摘要

the invention concerns a feinbohrwerkzeug for finish machining of pru00e4zisionsbohrungen, whose basic structure includes the following features: tool holders (11) with a cutter (13); a housing (101, 102) with zylinderbohrung in axialrichtung; stellschraube (105) with feingewinde,what in the zylinderbohrung housing drehbeweglich and axialfest is arranged and at its free end with a thumbwheel (104) is connected; schubteil (20, 21, 22), which is arranged in the zylinderbohrung drehfest and activity of stellschraube (105) in axialrichtung verse tellbar; shaft (23, 24).in a radialbohrung in the housing transverse to the longitudinal axis of the stellschraube (105) and led, and a linkage which, in zahnstangenartigen notches (20a) of the schubteils precisely as above. erfindungsgemu00e4u00df is the housing from an upper cylindrical housing (101) and a lower cylindrical housing associated with the (102).the dial (104) for the stellschraube (105) is coaxial between the upper housing and the lower housing are arranged. the tool holders (11) is on a cross member (10) arranged to the upper housing (101) transverse to the axis of the stellschraube (105) led to the shaft and movable (23, 24) is connected.
