Patent number: 10124431Abstract: A wire (12) is wound around multiple processing rollers (11) several times. A holding mechanism (13) and a depressing mechanism (25) are provided above an area where the wire (12) is wound. The holding mechanism (13) holds a workpiece (W) elastically and laterally. The depressing mechanism (25) depresses the workpiece (W) held by the holding mechanism (13) toward the wire (12).Type: GrantFiled: August 20, 2012Date of Patent: November 13, 2018Assignee: Komatsu NTC Ltd.Inventors: Hitoshi Shimada, Tomoyuki Kawatsu, Yosuke Yabu, Akira Tanizaki

Patent number: 9463517Abstract: In a single-wire type wire saw, a work is fed relatively to a wire stretched between a pair of grooved guide rollers disposed in the same direction and the work is cut by traveling the wire. When a cutting-feeding direction changes during a cutting of the work, an operation shaft is moved along an arc around the center axis of the wire in a cutting area and simultaneously support arms are rotated around the operation shaft to thereby oppose the wire support direction of the pair of grooved guide rollers to the cutting-feeding direction.Type: GrantFiled: March 18, 2015Date of Patent: October 11, 2016Assignee: Komatsu NTC Ltd.Inventors: Kikuo Koma, Tsutomu Sugihara, Akira Tanizaki, Akihiro Matsuda

Patent number: 7424846Abstract: A pneumatically static balancer for a machine tool counterbalances or lightens a gravitational load generated by an own weight of a vertically moving driven member. The pneumatically static balancer includes a pneumatic cylinder supporting the driven member and allowed to move vertically, a pneumatically static bearing having a piston inserted into the pneumatic cylinder, the pneumatic static bearing being formed by feeding compressed air, which is in an interior of the pneumatic cylinder, into a small clearance formed between the pneumatic cylinder and the piston, a cylinder rod connected to an upper end of the piston and a saddle supporting a leading end portion of the cylinder rod.Type: GrantFiled: April 14, 2006Date of Patent: September 16, 2008Assignee: Nippei Toyama CorporationInventors: Akira Tanizaki, Akira Takase, Shiro Murai
