Tsunehito NAKAHIGASHI has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11754993
    Abstract: A machine tool includes: a cover; a door; a drive mechanism; a detection unit; and an operation panel that receives an operation for the machine tool. A control device of the machine tool performs: processing to control the drive mechanism such that the door is opened, based on the operation panel receiving a first opening operation; processing to obtain an actual position from the detection unit and store the actual position as an opening position of the door, based on the operation panel receiving an operation to determine a position; and processing to control the drive mechanism such that the door is located at the opening position, based on the operation panel receiving a second opening operation. An opening speed of the door during the first opening operation is slower than an opening speed of the door during the second opening operation.

  • Publication number: 20180239332
    Abstract: A machine tool that attaches and detaches workpieces to and from a spindle in a shorter time includes: a machining mechanism part including a spindle, a tool rest, a first-axis feed mechanism moving the spindle in a a first axis extending along a center axis of the spindle, and a second-axis feed mechanism relatively moving the spindle and the tool rest in a second axis orthogonal to the first axis; a loading mechanism part including holding parts for holding a workpiece, and a third-axis feed mechanism moving the holding parts in a third axis orthogonal to the first axis to position them at the transfer position; and a numerical controller. The numerical controller operates to move the spindle toward the transfer position and to position the holding parts at the transfer position such that the operations at least partially overlap.
