  • Patent number: 10307876
    Abstract: A machine tool has a cover that prevents chips generated by machining and cutting fluid from scattering around and a plurality of movable nozzles with liquid discharge directions thereof being movable so as to wash out chips that have adhered to or accumulated on an inner surface of the cover. The machine tool is capable of changing a discharge direction of each of the movable nozzles individually. The machine tool compares the state of the inside of the cover before start of machining with the state of the inside of the cover after chips are generated to determine an adhesion or accumulation state of chips. The machine tool thus calculates the liquid discharge direction to wash out chips from the movable nozzles based on a result of the determination.

  • Patent number: 9952584
    Abstract: A system that can analyze and modify a point map file corresponding to a digital lens design is described. The digital lens design is optimized to meet a patient's ophthalmic prescription. However, a digital surfacing machine may not be physically capable of producing on a lens blank a lens curvature required by the prescription and defined by the point map file. The system takes into account limitations of physical characteristics of the digital surfacing machine, such as the diameter and speed of movement of the cutting tool, and modifies the point map file so that the digital surfacing machine can produce the lens curvature on the lens blank.

  • Patent number: 9339908
    Abstract: A machine tool has a cover structure adapted for the discharge of chips. The cover is composed of a front cover, left and right side covers, and a bottom part. The bottom part is connected to a bed through the respective lower ends of the front cover and the side covers. Further, at least a part of the bottom part includes a slope gradually inclining from the side connected to the bed toward the outer periphery. Even if the chips produced during machining adhere to members inside the cover, they are washed away by a cutting fluid and discharged into a cutting fluid supply device through a channel located farthest from the central portion of the machine tool.

    Abstract: A protecting cover for an X-axial screw of a carving machine includes a driven base positioned between an X-axial sliding base and an X-axial screw, and a hood. A through groove is bored in the driven base for the hood to pass through to surround the X-axial screw, enabling the driven base to move freely along the hood to effectively protect the X-axial screw. And as the hood doesn't have to be extended or compressed while the X-axial sliding base is moving, it can avoid the disadvantage of being easily broken that would happen to a conventional one owing to constant extending and compressing. So the protecting cover of the invention is pretty reliable.

  • Patent number: 8079788
    Abstract: A main body of a machine tool is covered with a cover. A ceiling portion of the cover that is situated over a spindle motor is provided with an opening portion. The cover is provided with hanging portions that hang down from the opening portion with a predetermined clearance from side surfaces of the spindle motor other than the rear surface. Air that is mixed with a misty cutting fluid in a space inside the cover is sucked in through a suction pipe by a mist collector. The outside air flows into the space inside the cover through the clearance. The outside air that passes through the clearance is driven to flow through vents by a built-in cooling fan of the spindle motor, thereby cooling the motor, and is then discharged to the outside. In consequence, the temperature in the space inside the cover can never be increased by heating of the spindle motor.
