Patent number: 8360695Abstract: An interface between a shank tool and a lubricant transfer area. The shank tool is arranged in a tool holder, and comprises a clamping section, a conical shank end and at least one internal lubricant duct comprising an orifice located in a tapered surface of the shank end outside a shank tool axis. The lubricant transfer area is provided in the tool holder, which encompasses an inner recess, and which narrows in the direction of a centrical lubricant feed pipe, the inner recess defining an inner cone supporting the conical shank end radially outside of the orifice. The conical shank end and the lubricant transfer area include a funnel-shaped lubricant transfer chamber, which extends between the centrical lubricant feed pipe and a tapered surface contact area between the inner cone of the lubricant transfer area and the conical shank end. Also, an adjustable screw for an interface as described above.Type: GrantFiled: December 11, 2008Date of Patent: January 29, 2013Assignee: Guehring OHGInventor: Peter Haenle

Patent number: 7275894Abstract: A rotationally driven cutting tool for machining of workpieces, in which at least one cutting insert is fastened detachably in a pocket of a blade bearer so that it is clamped flatly against a base surface of the pocket. For adjustment of the blade there is a cutting insert and a fine adjustment device with which, with the aid of an adjusting screw arrangement, an adjusting element supported on a lateral wall of the cutting insert can be adjusted relative to the cutting insert. The adjusting screw arrangement comprises a threaded sleeve that is held, preferably with play, in a smooth through opening having a narrow point and comprises a screw part in functional engagement therewith that stands in a chain of pressure force with the adjusting element.Type: GrantFiled: February 27, 2004Date of Patent: October 2, 2007Inventors: Uwe Schlagenhauf, Peter Haenle
