  • Patent number: 11130178
    Abstract: A machining tool includes a light irradiator, a cover, and a light blocking filter. The light irradiator is to irradiate a workpiece to process the workpiece. The cover covers the light irradiator and the workpiece in the cover. The light blocking filter is configured to change light transmissivity of the light blocking filter in accordance with light from an inside of the cover, which the light blocking filter receives.
    Type: Grant

  • Patent number: 8241191
    Abstract: The present invention aims at improving the efficiency of tool management by improving the arrangement of a tool magazine in a composite working lathe. The composite working lathe 1 includes a spindle stock and a tool spindle disposed on a bed 20, and a cover 2 covering the surrounding area thereof. A door 4 allowing access to a machining portion is provided on a front side F of the machine, and the machining portion can be visually observed through a window 5. A tool magazine unit 100 is disposed in front of the spindle stock of the machine. A door 120 and a window 130 are provided on the cover of the tool magazine unit 100, allowing operators to observe the tool stored in the magazine through windows 122 and 130. The present composite working lathe enables to improve the efficiency of tool management, such as the confirmation of the tool used in the subsequent step or the removal of chips on the used tool.

  • Patent number: 8051543
    Abstract: The invention provides a composite working lathe capable of improving the efficiency of workpiece machining area by arranging a workpiece handling device below a spindle of the composite working lathe. The composite working lathe 1 comprises a spindle 20 and a tool spindle 30 on a bed 10. A workpiece handling device 40 arranged below the spindle 20 can be moved along a W axis parallel to the axis line C1 of the spindle. The workpiece handling device 40 has a workpiece handling head 50 that pivots in the direction of arrow F around an axis line C2, and grips the workpiece K1 via a gripper 60. The axis line C2 is an axis perpendicular to the vertical plane including the axis line C1 of the spindle 20, and the workpiece handling head 50 is raised for 90 degrees when the gripper 60 receives the workpiece K1 from the spindle 20. The angular position of the workpiece handling head 50 is allocated and the workpiece K1 is machined via a tool T1 on the tool spindle 30.
