Patent number: 11318542Abstract: A tool-changing device which is used on machine tools (18). Here, provision is made to carry out positioning of a tool holder (2) in the working position (6) of the tool holder with the aid of the locking element (7) of the drive device (4) of the tool-changing device (1). An adjusting movement (22) of the locking element (7) into the locking position (9) of the locking element on the tool holder (2) that is required for the use of the tool (3) is used to position the tool holder (2) in the working position (6) thereof, by the adjusting movement (2) of the locking element (7) being converted into a positioning movement (21) of the tool holders (2).Type: GrantFiled: July 12, 2018Date of Patent: May 3, 2022Assignee: J.G. Weisser Söhne GmbH & Co. KGInventors: Florian Fehrenbacher, Thorsten Rettich, Reiner Jorg

Publication number: 20170300164Abstract: According to the invention, it is provided that, on a machine tool (1) which has a machine part (2) which can be adjusted by motor, a touch-sensitive display (4) is used to display the machine part (2) in its instantaneous state on the display (4) and to adjust said machine part by motor by a swiping gesture being executed on the display (4). The objective of this is to simplify operator control of the machine tool (1).Type: ApplicationFiled: October 4, 2016Publication date: October 19, 2017Applicant: J.G. Weisser Sohne GmbH & Co. KGInventor: Thorsten Rettich

Patent number: 9061354Abstract: A lathe (1) in which the work piece (16) to be lathed with a tool (18) is clamped with the longitudinal axis of the work piece parallel to the rotational axis (29) of the rotating clamping device (15) such that the rotational axis (29) does not intersect the work piece (16), and between two machining steps of the machining process by lathing, a position of the work piece (16) in the clamping device (15) is changed such that surface areas (30, 36) not previously machined are moved into the working area of the tool (18).Type: GrantFiled: August 11, 2010Date of Patent: June 23, 2015Assignee: J.G. Weisser Söhne GmbH & Co. KGInventors: Thorsten Rettich, Reiner Jörg

Patent number: 8904909Abstract: A device (1) for machining by turning rotationally symmetrical surfaces (18, 20 or 22) of a workpiece (10), which is clamped and has a rotating drive, including a tool (12) having two cutting edges (16) and (17), each having an approximately helical shape, which are disposed one behind the other in the feed direction of the tool (12) such that after the machining by turning with the first cutting edge (16), a roughing edge, the second cutting edge (17), a finishing edge, comes into engagement.Type: GrantFiled: June 1, 2011Date of Patent: December 9, 2014Assignee: J.G. Weisser Söhne GmbH & Co. KGInventors: Norbert Kummer, Peter Klaus

Patent number: 8640576Abstract: A production machine for non-circular workpieces provided with a tool feed unit (1) comprising a tool carrier (2) for receiving the tool and a compensation body (3) for impulse decoupling. The work movement of the tool carrier (2) can be effected by a drive (4) acting between the tool carrier (2) and the compensation body (3). The tool carrier (2) is supported by rolling bodies (5) and the compensation body (3) is suspended via elastically deformable guide elements (6) at a housing part (7) of the tool feed unit (1). A mass of the compensation body (3) is larger than a mass of the tool carrier (2) carrying the tool so that the working movements of the tool carrier (2) effect compensation strokes of the compensation body (3) that are only within the range of the elastic deformation of the guide elements (6). The guide elements (6) thus effect the guiding and resetting of the compensation body (3).Type: GrantFiled: August 7, 2009Date of Patent: February 4, 2014Assignee: J.G. Weisser Sohne GmbH & Co. KGInventor: Reiner Jorg
