Patent number: 11154962Abstract: A burnishing tool uses a relatively small pressing load in burnishing. The burnishing tool for machining a target surface of a workpiece includes a base and a tip portion located on a distal end of the base. The tip portion includes a linear slide-contact portion that linearly contacts and slides on the target surface.Type: GrantFiled: March 7, 2018Date of Patent: October 26, 2021Assignee: SUGINO MACHINE LIMITEDInventors: Daichi Kamimura, Masaru Futamura

Patent number: 10792787Abstract: A burnishing machine is provided in which both sides of a groove is machined by a single tool without changing the movement direction of a piston. The burnishing machine, includes: a tip configured to press and process a process face; and a pressurizing unit configured to press the tip against the process face, the pressurizing unit including, a piston configured to reciprocate in a direction orthogonal to the tip, a cylinder portion that accommodates the piston such that the piston reciprocates; and a pressurizing mechanism configured to urge the tip to the process face at both timing of pushing the tip against the process face and pulling the tip against the process face by making the piston reciprocate.Type: GrantFiled: May 23, 2019Date of Patent: October 6, 2020Assignee: SUGINO MACHINE LIMITEDInventors: Daichi Kamimura, Masahide Ohashi, Masaru Futamura

Patent number: 8931320Abstract: A dimple-forming burnishing tool allowing easy adjustment of a dimple shape is provided. The dimple-forming burnishing tool has a mandrel attached on a rear-end side thereof to a processing machine for rotation, and a cylindrical frame rotatably externally fitted on a tip side of the mandrel and holding a rolling element and a pressing element that are driven by rotation of the mandrel, for forming dimples in an inner surface of a workpiece by rotating the mandrel with the frame disposed inside the inner surface of the workpiece. In the dimple-forming burnishing tool, the mandrel includes a dimple adjusting mechanism. The dimple adjusting mechanism includes: a rolling element rotating portion causing the rolling element to rotate without moving in and out radially of the frame; and a pressing element in-and-out rotating portion causing the pressing element to rotate while moving in and out radially of the frame.Type: GrantFiled: December 15, 2011Date of Patent: January 13, 2015Assignee: Sugino Machine LimitedInventors: Shinya Miyauchi, Tetsuya Suzuki, Masaru Futamura
