20200130120 | MACHINE TOOL AND GEAR MACHINING METHOD - A machine tool includes a workpiece holder, a tool holder holding working tools that includes a hob cutter used in a rough machining and a skiving cutter used in a finish machining, a tool magazine, a tool replacing device replacing one of the working tools mounted on the tool holder with the other of working tools housed in the tool magazine, a rough machining controlling section performing the rough machining on the workpiece, a tool measuring device measuring a position of a blade in a rotation direction of the skiving cutter, an angle correcting section correcting a rotation angle of the skiving cutter based on a result measured by the tool measuring device, and placing a tooth space formed in the workpiece and an edge tip of the blade in a position corresponding to each other, and a finish machining controlling section by which workpiece is finish machined. | 2020-04-30 |
20200130121 | SPINDLE DEVICE - A spindle device includes a spindle shaft, a spindle housing, and a chuck portion as a rotating member. The chuck portion has, formed therein, a suctioning passage through which air suctioned from the outside flows. The spindle shaft has a first guide passage which guides air flowing through the suctioning passage to a clearance between the inner wall of the spindle housing defining a through hole in which the spindle shaft is inserted and the outer wall of the spindle shaft facing the inner wall, by way of the interior of the spindle shaft. The spindle housing has, formed therein, a second guide passage configured to guide the air guided to the clearance, to the outside. | 2020-04-30 |
20200130122 | SPINDLE DEVICE - A chuck unit as a rotating member of a spindle device includes a base portion fixed to one end of the spindle shaft, an attaching portion detachably attached to a side of the base portion that is located on an opposite side of the base portion from the one end of the spindle shaft, and an accommodation space arranged on a communication passage so as to accommodate a filter. | 2020-04-30 |
20200130123 | MACHINE TOOL - A machine tool equipped with a robot includes a stocker which has one or more effector holder units for holding an end effector to be mounted on the robot, in which the stocker can be stored within a casing of the machine tool. At least a part of the stocker is configured to be bilaterally advanceable into a machining chamber of the machine tool and an external region located outside the machine tool. | 2020-04-30 |
20200130124 | GRINDING APPARATUS, GRINDING METHOD AND COMPUTER-READABLE RECORDING MEDIUM - A grinding apparatus configured to grind a substrate includes a substrate holder configured to hold the substrate; and an annular grinder configured to come into contact with at least a central portion and a peripheral portion of the substrate held by the substrate holder to grind the substrate. The substrate holder includes multiple substrate holders and the grinder includes multiple grinders. A diameter of at least one of the multiple grinders is different from a diameter of others of the multiple grinders. | 2020-04-30 |
