  • Patent number: 10434616
    Abstract: Provided is a highly practical machining system. The machining system is configured to include a base, and multiple machining modules which are detachably disposed on the base to be aligned with one another in a left-right direction. Machining is sequentially performed by the multiple machining modules with respect to a workpiece. At least one of the multiple machining modules is a vertical lathe module. It is possible to configure a compact system in which machining can be performed by a vertical lathe.

  • Patent number: 10058967
    Abstract: A manufacturing system including a base and multiple work machine modules that are arranged in an arrangement direction on base to be attachable to and detachable from base, in which one wheel of a pair provided on work machine module is engaged with one rail of a pair provided on base in a state in which positional deviation in the arrangement direction is prohibited, and the other wheel of the pair is engaged with the other rail of the pair in a state in which positional deviation is permitted in the arrangement direction, thereby the position of work machine modules on the base in the arrangement direction is specified, and work machine modules are fixed at a setting position on the base to be restricted so as to be drawn toward the base by a module fixing mechanism that is provided on the base.

  • Patent number: 9522429
    Abstract: A workpiece machining apparatus including a headstock to which a workpiece having a through-hole extending in a Z-axis direction is attached; a tool rest which is movable in the Z-axis direction and in an X-axis direction; and a rotary tool unit which is attached to the tool rest, is provided. The headstock has a support member which is movable in the Z-axis direction and which has a spindle side contact portion in an end portion in the Z-axis direction. The rotary tool unit has a tool body having a tool side contact portion with which the spindle side contact portion can come into contact in the Z-axis direction, and a rotatable tool which protrudes from the tool body. The rotating tool machines the workpiece by moving the tool body in the Z-axis direction in a state where the spindle side contact portion and the tool side contact portion are brought into contact with each other.
