| 20080247835 | MACHINE TOOL WITH MAIN BODY COVERED WITH COVER - 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. | 10-09-2008 |

The foreign-matter receiving clearance is defined in a range of +30° to −30° from a cutting-edge position of the throwaway tip assumed as an original point and in a range of 150° to 210° from the original point, respectively. | 02-17-2011 |
| 20120141219 | AUTOMATED LOADING OF WORK PIECES INTO ADVERSE ENVIRONMENTS ASSOCIATED WITH MILLING MACHINES - Embodiments relate generally to milling machines and milling techniques, and more particularly, to devices, integrated circuits, computer readable media, apparatuses, milling machines and methods to automatically load and/or unload work pieces in relation to the adverse milling machine environments. In one embodiment, an apparatus includes a loader member configured to impart a loading force unto a work piece to position the work piece in a milling region. The apparatus can also include an effector configured to transfer the loading force from the loader member to the work piece and is configured further to apply a cleaning force to a path that the work piece traverses to the milling region. In some cases, the apparatus can include an ejector configured to remove a milled work piece from the milling region. | 06-07-2012 |
| 20130039713 | MODULAR MACHINE TOOLS - Modular machine tools, modular machine-tool beds, and systems for assembling the same are disclosed. Some machine tools and beds may be configured selectively between a cantilever configuration and a gantry configuration. Some modular beds may be assembled selectively to have a desired longitudinal length. The modular nature of the machine tools and modular beds allows users to configure a machine tool in multiple configurations depending on a particular work piece needing to be worked. | 02-14-2013 |
| 20130078046 | PROTECTING COVER FOR AN X-AXIAL SCREW OF A CARVING MACHINE - 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. | 03-28-2013 |
| 20140079500 | MACHINING APPARATUS WITH CHIP SHIELD - An apparatus for machining metal workpieces has a frame defining machining, pick-up, and drop-off stations. A vertical slide is vertically shiftable on the machine frame. In turn a horizontal slide carrying a rotatably driven holder is horizontally shiftable on the vertical slide between respective pick-up, machining, and drop-off positions above the stations. A holder is provided in the machining station, and one of the holders is adapted to hold a tool and the other of the holders for holding a workpiece for machining the workpiece in the machining station. A pair of shields is fixed to the vertical slide and horizontally flanks the machining station. One of the shields is between the machining station and the pick-up station. Respective slidable doors on each of the shields are shiftable between a closed position blocking movement of the rotatable holder past the respective shield and an open position permitting such movement. | 03-20-2014 |
| 20140169902 | SPINDLE JIG AND AUTO PALLET-CHANGEABLE MACHINING CENTER HAVING THE SAME - A spindle jig and a machining center having the same are disclosed.
