Patent number: 11904396Abstract: A method wherein a first workpiece (2, 40) is loaded to a spindle (30) of a workpiece processing machine with the first toothed workpiece having a predetermined design and being in a predetermined rotational load position. The first toothed workpiece is stock-divided and a machining position is determined based on the stock-dividing. The first toothed workpiece is rotationally adjusted to the machining position. The teeth (3, 42) of the first toothed workpiece are then machined and the first workpiece is removed from the spindle. A second toothed workpiece is loaded to the spindle of the workpiece processing machine. The second toothed workpiece has the same predetermined design and is in the same predetermined rotational load position as the first toothed workpiece. The second toothed workpiece is rotationally adjusted from the predetermined rotational load position to the machining position by the same adjustment amount as the first toothed workpiece.Type: GrantFiled: September 5, 2019Date of Patent: February 20, 2024Assignee: THE GLEASON WORKSInventors: Craig R. Ronald, Uwe Gaiser, Daniel J. Schwab, Matthew J. McNall, Bryan L. Patterson, Kevin H. Blakely, William D. McGlasson

Patent number: 8961081Abstract: Gear processing machine (4), such as a gear cutting or grinding machine, wherein a chamfering and/or deburring apparatus (2) and auxiliary spindle (10) are included on the same machine. A transfer mechanism (8) loads, unloads and transfers workpieces between a machining spindle (6) and the auxiliary spindle (10) thereby enabling simultaneous cutting and chamfering and/or deburring processes to be carried out. Via the auxiliary spindle, completed workpieces may be removed from the machine and blank workpieces may be loaded into the machine while another gear is being processed on the machine spindle thereby enhancing machine output and creating a more efficient operation.Type: GrantFiled: September 24, 2010Date of Patent: February 24, 2015Assignee: The Gleason WorksInventors: Craig R. Ronald, Alan S. Metelsky

Patent number: 8777230Abstract: A tool securing device capable of clamping a tool to a machine spindle as well as assisting in the removal of a tool from a machine spindle, all in a tool-less manner. The tool securing device includes distal means to be releasably gripped by a machine draw bar as well as means to releasably engage a tool.Type: GrantFiled: April 28, 2011Date of Patent: July 15, 2014Assignee: The Gleason WorksInventors: Craig R. Ronald, Matthew C. Meyer, David J. Senecal, Daniel D. Wood, Kenneth E. Glasow

Publication number: 20120161404Abstract: The present invention is directed to an arbor chuck workholding assembly comprising an arbor chuck (2), outer ring (6), clamp ring (8) and backing ring (10). The arbor chuck comprises a plurality of holding angle lugs (18) and ejecting angle lugs (20) located about its periphery. The outer ring (6) comprises a plurality of complementary holding angle ramps (22) and ejecting angle ramps (24) located on its inner diameter surface. A machine spindle (4) is rotated to engage the holding angled lugs (18) with the holding angle ramps (22) such that the arbor chuck will be drawn into position against the spindle. For disengaging, a reverse rotation of the spindle will result in ejecting angle ramps (24) engaging ejecting angle lugs(20) to loosen the arbor chuck from the spindle. Therefore, no tools are required to secure the arbor chuck to the machine spindle.Type: ApplicationFiled: September 14, 2010Publication date: June 28, 2012Applicant: THE GLEASON WORKSInventors: Craig R. Ronald, Donald L. Allis, Kenneth E. Glasow
