To enable machining by means of cutting tools as well as machining by means of a laser beam with a construction of simple design without complicated exchange operations, the beam guiding arrangement is arranged on the machining unit so that it is displaced with respect to the work spindle.

Abstract: A machine tool with a working area cover provided with at least one door for allowing access to the working area of the machine tool. For providing an enhanced and simplified access to the working area without interfering protrusions or edges the door is a round door turnable about a vertical axis.

Abstract: A universal combined milling and boring machine having a machine column, a compound slide that can traverse horizontally on the machine column, a spindle head mounted on the compound slide so that it can traverse vertically, with a work spindle, a rotary table mounted so it can pivot over a supporting console on the machine column and a control unit. Multiaxial machining with relatively inexpensive control technology and a control system with optimum visual contact with the machining site are made possible according to this invention due to the fact that the supporting console is mounted on the machine column so it can rotate about a horizontal swivel axis. The swivel axis is offset laterally relative to the central axis of the combined milling and boring machine; the rotary table is mounted centrally on the console so it can rotate about an axis of rotation normal to the swivel axis; and the control unit includes a portable control console.

Abstract: The invention concerns a drive assembly for relative movement of two components of a machine tool with a drive motor and a gear arrangement with two gear trains that can be put under tension relative to each other and have output gears that mesh with opposing teeth, where each gear train has a compact gear with a high transmission ratio with at least one control element for applying tension to the two gear trains. A high positioning accuracy and torsional rigidity combined with a small size when installed are made possible according to this invention by the fact that the compact gear.

Abstract: A spindle unit for machine tools, with a working spindle that is provided to accommodate a tool and is mounted so it can rotate in a housing and is driven by a motor, and with a chucking unit with an operating device and an internal coolant supply to the tool. A short and compact spindle unit is created according to this invention by the fact that the internal coolant supply is integrated into the chucking unit and has a rotary transmission lead-through mounted inside the operating device to convey the coolant from a stationary supply line into the chucking unit.

Abstract: A program-controlled machine tool with automated tool changing, where the machine tool consists of a motor-driven machining unit with a working spindle that can be moved in at least one coordinate. The machine tool also includes a work table that can be driven by a motor in at least one coordinate, at least one tool magazine, and a programmable control unit. In order to be able to carry out tool changing operations without any auxiliary equipment, especially without a tool changer, within a short period of time, the tool magazine is mounted in a certain spatial arrangement with the working area of the machining unit so that its changing position can be approached directly by the working spindle in order to carry out the tool changing operation.

Abstract: Apparatus for cleaning fluids, especially cooling lubricants of machine tools. The apparatus includes a tank having a partition subdividing it into a sedimentation chamber and a clean chamber and having an inlet for the contaminated cooling lubricant and a discharge device for the cleaned cooling lubricant. A filter is mounted between the sedimentation chamber and the clean chamber and a conveyor device is mounted in the sedimentation chamber for removing sedimented particles from the tank. An environmentally safe and low-maintenance cleaning apparatus according to this invention is created by the fact that the sedimentation chamber is subdivided by a partition into an inlet area and a preliminary cleaning area that are connected to each other by a passage in the lower area of the partition. The filter is an edge filter mounted in the partition between the preliminary cleaning area and the clean chamber.

Abstract: A machine tool for multiaxial machining of a workpiece in a chuck. Both horizontal and vertical motion are provided. Even greater efficiency can be achieved by properly positioning tool magazines and providing at least two work stations in adjacent relationship.

Abstract: A control console for a program-controlled machine tool consisting of a base, an ergonomically positioned control panel including a plurality of function keys, and a display screen. The control panel and the display screen are provided in a common control console housing. In a recess of the housing a plurality of separate control panels is provided, which can be alternatively positioned with respect to the control surface of the control console housing. The functional elements of those control panels are connectable to the associated elements in the control console via electric connectors.

Abstract: A protective panel for the work area of a machine tool, consisting of a plurality of segments which are movably interconnected by connection elements. The segments are formed as frames which are nested into each other and shiftable with respect to each other by means of connection elements, the maximum displacement path of the single frame being smaller than the bridge width of the nearest greater size frame.

Abstract: A universal milling and drilling machine provided with a swivel milling head for an automatic reset from horizontal to vertical machining. The driving of the work spindle is carried out by a driving motor via bevel gears and a shift transmission which ensures a high torque even in a low rotation speed range. For optimizing the power transmission between the driving motor and the work spindle, the shift transmission is arranged in the swivel milling head, and the bevel gear transmission is seated directly on the motor shaft of the driving motor. The swivel milling head is mounted on the front surface of a support housing, the front surface being downwardly inclined by 45.degree..

Abstract: A device for positioning a pallet on a work table. The device consists of a vertically movable pallet carrier for transport and for raising and lowering a pallet that is provided with clamping elements on the lower side and at least one clamping device that is provided in the work table. The clamping device can be actuated by vertical movements of the pallet carrier. It has at least one wedge-type valve for clamping a clamping element on the pallet that has been deposited. The clamping device also has at least one control element that can be operated by the pallet carrier for releasing the clamp against the force of the springs, where the control element is mounted directly on one of the wedge-type valves.
