Patent number: 7243583Abstract: The multi-spindle automatic lathe (10) has an apparatus for machining the rear side of a workpiece (15). For this, it is provided with a transfer device (21) for removing a workpiece machined at its front side from a primary workpiece spindle (15) of the machine and for transferring the workpiece to a machining station (22) for the rear side machining, whereby the transfer device comprises a gripper (23) as well as a translation device (24) moveable parallel or coaxially to the workpiece spindle (14) between this and a rear wall (19) of the machining chamber, which translation device takes up the workpiece from the gripper for transfer to the machining station for the rear side machining.Type: GrantFiled: April 5, 2005Date of Patent: July 17, 2007Assignee: Alfred H. Schutte GmbH & Co. KGInventors: Markus Krell, Albert Herrscher

Patent number: 7226340Abstract: The grinding machine (10) according to the invention serves in particular for the machining or production of tools. It comprises a machine bed 11 and a workpiece spindle (14) arranged thereon, which receives the workpiece (13) to be machined, as well as a grinding station (19) arranged next to the workpiece, the station having a grinding spindle for the reception of a grinding tool (20), and is provided with a workpiece guide system (23) arranged at the machine bed for the support of the workpiece at the grinding location (21).Type: GrantFiled: March 4, 2005Date of Patent: June 5, 2007Assignee: Alfred H. Schutte GmbH & Co. KGInventors: Viktor Kopp, Wilfried Saxler

Patent number: 6190242Abstract: A universal grinding machine having a plurality of workpiece holders, each of which can be moved independently of each other or jointly, by a separate slide, in the longitudinal direction of the workpiece on a slide guide disposed on the machine bed, or which can be fixed independently of each other or jointly to the machine bed.Type: GrantFiled: September 24, 1999Date of Patent: February 20, 2001Assignee: Alfred H. Schutte GmbH & Co. KGInventors: Albert Herrscher, Victor Kopp

Patent number: 6126526Abstract: A universal grinding machine, particularly for the grinding of tools, having a tool magazine in which a plurality of grinding tools, together with coolant supply devices which are matched thereto, are disposed in holders and can be supplied according to choice to the grinding spindle, where the grinding tool and its coolant supply device are introduced into their receivers; simultaneously by an axial movement of the grinding spindle and of the grinding spindle slide and are withdrawn by a movement of the grinding spindle and of its grinding spindle slide perpendicular to the grinding spindle axis so that the grinding tool and the coolant supply device are always in a position in relation to each other which is correct for machining.Type: GrantFiled: September 24, 1999Date of Patent: October 3, 2000Assignee: Alfred H. Schutte GmbH & Co., KGInventors: Albert Herrscher, Victor Kopp

Patent number: 5581863Abstract: An electronic control device for individual drives of machining machines, particularly of machine tools with a plurality of drive apparatuses, in which, according to the counting state of a pulse counter (35), path information elements associated with the latter are extracted simultaneously by a computer unit (37) from memories (41, 42, 43) associated with many drive apparatuses (18, 19, 20) and are converted into control values necessary for machining, which control values are then fed as set values to control circuits (30, 31, 32) for the drive apparatuses (18, 19, 20). The electronic control device (37) is supplied with a low counting pulse frequency (f.sub.z) and can therefore process path and speed information values from a memory unit (36) for very many drives (18, 19, 20) simultaneously.Type: GrantFiled: March 1, 1995Date of Patent: December 10, 1996Assignee: Alfred H. Schutte GmbH & Co. KGInventor: Detlef Langer
