A chip collecting apparatus for a machine tool has two separate chip conveyors for chips of different materials. The chip collecting apparatus receives chips on fixed guide plates. Chips are washed from the fixed guide plates into a chip collecting area. In the chip collecting area is disposed a change-over plate for directing the chips from the guide plates onto either one of the chip conveyors. The change-over plate is pivotably moveable between different positions corresponding to the respective chip conveyors. In an alternative embodiment, only one chip conveyor is used, and the change-over plate is provided at the discharge end of the conveyor to discharge chips into either one of two chip collecting bins.

Machine tool having a chip collecting apparatus

A machining tool is provided with an electric discharge truing/dressing apparatus comprising a spindle stock for containing and supporting a workpiece spindle which is driven for rotation while holding a workpiece or an electrode; a tool rest which moves parallel and perpendicular to the spindle of the spindle stock and holds an electrode machining tool and a grinding wheel; a feed electricity means disposed between a workpiece supporting portion of the spindle and the tool rest; a magazine disposed at an outside area of a machining area of the tool rest and adapted to store the workpiece and the electrode; and a loading device disposed between the magazine and the spindle. The grinding wheel on the tool rest is subjected to truing/dressing by feeding the electrode from the magazine to the spindle stock.

Machine tool with grinding function and truing/dressing method of

A machining tool with an electric discharge truing and dressing apparatus comprising a spindle stock for containing and supporting a workpiece spindle which is driven for rotation while holding a workpiece or an electrode. A tool rest moves parallel and perpendicular to the spindle of the spindle stock and holds an electrode machining tool and a grinding wheel. An electricity feed element is disposed between a workpiece supportng portion of the spindle and the tool rest. A magazine is disposed at an outside area of a machining area of the tool rest and is adapted to store the workpiece and the electrode. A loading device is disposed between the magazine and the spindle. The grinding wheel on the tool rest is subjected to truing and dressing by feeding the electrode from the magazine to the spindle stock.

A composite machining lathe having a tool holder base movable in the direction of the axis of the spindle and a tool magazine. The tool magazine has a continuous elongated flexible tool carrier adapted to run along a path having a curved section. A plurality of tools are carried by the tool carrier in such a manner that the tools on the portion of the tool carrier in the curved section of the path are selectively engageable with a head bore formed in the tool holder base. The tool magazine is mounted such as to be movable together with the tool holder base in synchronism in the direction of axis of the spindle and in the direction perpendicular to the axis of the spindle. The tool holder base is mounted in such a manner that it is movable to and from a retracted position relatively to the tool magazine. Tool holding means are provided on the tool holder base for holding the tools on the tool carrier. The selected tool to be used in the machining is moved to the curved section of the path of the tool carrier where the distance between adjacent tools is increased to avoid any interference between adjacent tools, while other tools are densely arranged on the straight portion of the tool carrier. The number of tools employed can be increased by the use of a supplementary tool magazine storing a number of tools.
