Abstract: The invention relates to extrusion and pipe presses (1), comprising a press frame consisting of a cylindrical spar (2) and a counter spar (4) connected thereto, in which a mobile billet container holder (7) supporting a billet container (8), which puts a billet (18) to be pressed, which was introduced by a loading device, into a press position in front of the counter spar (4) with the associated tool (38), and a mobile punch crosshead (6) are provided. In the cylindrical spar (2), a main cylinder, or press cylinder, is arranged, which in the cylinder housing (9) thereof receives a press piston (11), which at the front end thereof that is supported by the punch crosshead (6) is connected to a press punch (19). A compensation tank (15), which delivers hydraulic oil to the press piston (11) by way of a slider plate (28), is assigned to a main cylinder housing (9) connected to a tank line.

Abstract: A broaching device is provided with puller heads (132,134) that hold tip portions of broaches (116) and are supported in a horizontally freely movable manner, main motors (136, 140) capable of moving the puller heads (132, 134), retriever heads (133,135) that hold base end portions of the broaches (116) and are supported in a horizontally freely movable manner, sub motors (138,142) capable of moving the retriever heads (133,135), and a control device (117) that enables the puller heads (132,134) and the retriever heads (133, 135) to be synchronized with each other and to move at a fixed speed by controlling the motors (136,138,140,142), whereby machining accuracy can be improved.

Abstract: A process for the manufacturing of longitudinal profiles such and tongue and groove on boards wherein the process includes the steps; a) Moulding a substantial part of the profile cross-section by means of milling with a milling tool. b) Fine moulding undercuts in at least the groove of the board by means of broaching utilising at least one broaching tool.

Abstract: An apparatus and method for aligning a crankpin grinding machine of the type having a pair of opposite facing workheads for mounting a crankshaft on its end journals and rotating the crankshaft about an axis passing through selected crankpins during the grinding of the selected crankpins and an indexing device in one of said workheads for indexing the crankshaft about the axis of the end journals to position and grind other selected crankpins. The apparatus is comprised of a laser for projecting a narrow collimated beam of light, a photoelectric target to intercept the target and produce an output which is indicative of where the laser beam intersects the target, an input-output unit to process the output of the target and display information to an operator; and special adapters to mount the laser and target on the crankpin grinding machine to align the workheads, workholders and indexing device of the machine.

Abstract: An automatic machine tool having a tool holder for moving a plurality of tools into working relation to a plurality of work parts, and mechanically actuated means effective to terminate machine operation if any one tool is missing from the tool holder.

Abstract: An accessory for tool machines is provided comprising a tool holder isolatedly carried on bar springs to effect a floating mount. The holder yields in response to selective load stress during cutting and is restricted to a linear force path to relieve stress. The yielding movement relieves stress and can operate signals in the event of overload or operate control means such as switches to cut off tool machine motors.
