The input of the drive is connected via a control signal transmission circuit and a transducer to the output of a system for digital programming control (DPC). A sensor for checking variations in the wall thickness of the component, a sensor of the angle of rotation of the component, a sensor of the angle of rotation of the cutter head and a sensor for checking the wobbling of the component are connected to the DPC system. The drive of the device for displacing the cutter in the radial direction is in the form of a linear drive and is mounted on the cutter head. The technical result is expressed in an increase in the accuracy of machining deep openings while ensuring that said openings can be corrected during the process of machining the openings.Type: GrantFiled: August 2, 2010Date of Patent: January 26, 2016Inventor: Mikhail Vladimirovich Vedel

Patent number: 9242330Abstract: A skate blade sharpening system includes a clamp for retaining a skate blade in a sharpening position during a sharpening operation, with a centerline of the sharpening position having a first predetermined location relative to a first visual reference feature. A grinding wheel contacts the skate blade during sharpening and is mounted for rotation on a motor arm. A centerline of the grinding wheel has a second predetermined location relative to a second visual reference feature carried by the motor arm. An adjustment mechanism is used to move the motor arm transversely during an alignment operation to vary relative position between the grinding wheel and the sharpening position across a range that includes an aligned position in which the centerline of the grinding wheel is aligned with the centerline of the sharpening position. The aligned position is indicated by alignment of the first visual reference with the second visual reference feature.Type: GrantFiled: October 24, 2014Date of Patent: January 26, 2016Assignee: VELASA SPORTS, INC.Inventors: Russell K. Layton, Jr., Daniel A. Beaudet, Ivan D. Goryachev

Patent number: 9242331Abstract: An electric sharpener for sharpening ceramic blades includes at least one stage. The stage is a finishing station having a sharpening member in the form of a disc which comprises a rigid support having a flexible abrasive matrix which both sharpens and polishes the facet of the ceramic blade. The sharpener may include a pre-sharpening stage for metal blades and a further pre-sharpening stage for ceramic blades. The sharpener also includes a removable guide.Type: GrantFiled: March 12, 2015Date of Patent: January 26, 2016Assignee: Edgecraft CorporationInventors: Bela Elek, George C. Jensen, Daniel D. Friel, Jr., Samuel Weiner

Patent number: 9242332Abstract: On a workpiece there are first longitudinal portions which are rotationally symmetrical with respect to the continuous longitudinal axis and are intended to be ground by way of centerless grinding. The workpiece also has a second longitudinal portion, which is not rotationally symmetrical with respect to the longitudinal axis and would lead to imbalance in the event of rotation. Therefore, a balancing weight having a radially extending recess is placed on the second longitudinal portion. The balancing weight contributes largely to uniform distribution of the rotating masses, thus reduces the imbalance to a very low residual imbalance and allows reliable and precise centerless grinding.Type: GrantFiled: August 30, 2011Date of Patent: January 26, 2016Assignee: Erwin Junker Grinding Technology A.S.Inventors: Erwin Junker, Hubert Mueller

Patent number: 9242334Abstract: The invention discloses a transform mechanism of a finishing wheel for an abrasive belt polishing finisher in the field of mechanical technology. The invention is disposed on the inner side of the abrasive belt of the finisher, comprising several slide rails disposed on the side of the frame of the finisher and sliders on the slide rails. A finishing wheel is fixedly connected with each of the sliders. The curved surface of the rim of each of the said finishing wheels has a different curvature. A driving element connected with the slider is provided on the frame of the finisher close to each of the sliders. The finishing wheel corresponding to the driving element, driven by the said driving element, is pressed against the inner side of the abrasive belt. The transform mechanism of the invention could be widely applied and has a high polishing and finishing efficiency.Type: GrantFiled: August 3, 2014Date of Patent: January 26, 2016Assignee: Taizhou Federal Robot Technology Co., LtdInventor: Qiyue Chen
