A relatively compact, program-controlled, universal combined milling and boring machine having a horizontal base as a support for a work table, a machine frame and a supporting system for at least one spindle head. The spindle head contains a dimensionally stable central tube, a spindle head support mounted on the lower end thereof, three telescopic bars arranged at a solid angle displacement of about 120&deg; and coupled to the spindle head support in universal bearings, and an upper support member having universal bearings for the central tube and for each telescopic bar. The machine frame is preferably provided together with the base as an integrated, dimensionally stable, support structure and has two side walls, a top, front traverse and a lower rear wall. The supporting member of the supporting system is inclined between the top side of rear wall and the traverse.

Universal combined milling and boring machine

A machine tool for metal cutting having a collecting system for chips and liquids. Disposed below the work area is a pan having a transverse groove, a chip conveyor disposed in the transverse groove, a spiral-shaped conveyor element, a liquid collector on one side wall of the pan and a chip outlet disposed on the other side wall of the pan on the outlet end of the chip conveyor. To enhance the separation of liquids even when a large amount of chips is produced, an elongated screen element is disposed in the inner cavity of the spiral-shaped conveyor element, the screen element extending over at least part of the length of the conveyor element and terminating at the liquid collector.

Machine tool comprising a collecting system for chips and liquids

A machine tool comprising a machining spindle, a device for inserting an auxiliary unit into the machining spindle, a tool magazine for providing a multitude of tools and a tool changer comprising at least one tool gripper for holding tools for the machining spindle for the transportation of tools between the tool magazine and an exchange position at the machining spindle. To ensure an automatic supply to the machining spindle as well as to the auxiliary unit in a simple and fast way the tool changer has at least one additional tool gripper for holding tools for the auxiliary unit.

Machine tool

A machine tool for cutting workpieces, the machine tool having a tool slide shiftable on or along a machine tool table as support of a machining unit. The machining unit has at least one work spindle and a workpiece support for receiving the workpieces to be machined. For enabling fast machining including an accurate and rapid positioning of the machining unit with as few linear guidances as possible, the tool slide has a transverse support shiftably guided on or along the machine tool table and also has two cross slides shiftable in its longitudinal direction. The machining unit is jointedly arranged between the cross slides via a coupling mechanism having at least two dimensionally stable swivel arms for axially moving the work spindle.

A machining unit on a machine tool, especially a universal milling and drilling machine, comprising a motor-driven work spindle rotatably mounted in a casing of a spindle head, an adapter unit comprising a motor-driven adapter spindle and insertable into the work spindle, a first connecting part disposed on the spindle head and containing plug-in connections connected by lines to supplies of working media and a second connecting part disposed on the adapter unit, and containing mating plugs which can be coupled to the plug-in connections for releasably connecting the adapter unit to the working-media supply. A clamping device for releasably holding the plug-in connections and mating connections in the coupled position is disposed on at least one of the two connecting parts, thus providing a secure connection between the plug-in connections disposed in the spindle casing and the mating connections disposed on the adapter unit.

Machining unit on a machine tool

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.

Machine tool with a working area cover

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.

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.

Programmable machine tool with automatic tool changer

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.

A tool changing assembly for program controlled milling and drilling machines comprising a vertically movable knee-type unit for the work table, and a vertical milling head. The tool changing assembly includes a power-driven pivotable mounting which is arranged in the form of a bracket for pivoting movement about a vertical axis on a column mounted on the knee-type unit laterally spaced from the work spindle of the milling head. The free end of the bracket has gripping pliers mounted thereon for pivoting movement about a likewise vertical axis, the pivoting movement of the gripping pliers being opposite to the pivoting movement of the bracket and being derived therefrom.

Tool changing assembly for universal milling and drilling machines

A tool changing device for program-controlled universal milling and drilling machines as well as machining centers. The device comprises at least one gripper movable in plural axes between a tool magazine and the horizontal and vertical work spindles respectively. The gripper is secured to a program-controlled motor-driven support and transfers the tools from the transfer position of the tool magazine to the horizontal or vertical work spindle. In accordance with the disclosure a bracket is mounted on a cross member secured to a sidewall of the machine frame, the bracket being axially movable and pivotable within predetermined limit positions. A bent or cranked support is mounted on the free end of the bracket for rotation therewith and carries a 90.degree.-rotatable cross-arm including the gripper.
