Abstract:
The present disclosure relates to a machine tool, such as a moving column-type machining center, and a method of operating the same, which are capable of shortening tool change time, improving productivity, minimizing a collision or mechanical interference, and increasing stability and reliability in a medium-sized or large-sized machine tool having a long length in a width direction by means of a magazine installed on a saddle, a tool changing unit movably installed on the saddle, and a tool changing unit transfer part configured to move the tool changing unit independently of a column.
Abstract:
In a tool storing device handling a tool mounting stocker in which a punch and a die of a press brake are mounted in one stocker with rear surfaces facing each other, each of the stockers is supported on both sides by endless belts having one driving shaft, and the endless belts are circulated so that each of the supported stockers does not protrude to a worker side, whereby a position of a path line of the appropriate one of the stockers can be freely positioned at a position of the path line PL of a tool holder on the press brake side. This enables rapid and easy tool replacement by a bending robot by storing not only the tool made of the punch and the die but also the hand for the robot together.
Abstract:
A method is proposed for controlling tool change operations on a machine tool, wherein a machining procedure on a workpiece includes a sequence of machining operations having in each case a particular tool and in each case a particular duration, and for a tool change, tools of a tool spindle are provided by a second storage device in communication with a first storage device, and wherein there is associated with the machining procedure a sequence of tool provision operations in which a tool provision operation has in each case a particular duration, wherein the method includes a determination stage wherein the durations of the machining operations and the tool provision operations are determined, and a control stage wherein the tool provision operations are temporally grouped in relation to the machining operations such that the tool provision operations bring about a minimized idle time in the machining procedure.
Abstract:
An apparatus and a system comprise a collet comprising a top portion and a bottom portion. The top portion comprises a threading means. The bottom portion at least comprises means for holding the collet from rotating and means for retaining an end mill. A master comprises a top portion and a bottom portion. The top portion is configured for engagement with a spindle of a milling machine. The bottom portion comprises a threading means for engagement with the threading means of the collet, wherein the master is retained by the spindle and the collet engages and disengages the master by rotation of the spindle. The milling machine operates under computer control during engagement and disengagement of the collet from the master.
Abstract:
A method of manufacturing a transmission case housing is provided wherein a minimum quantity of lubrication as a compressed air/oil mist is supplied as the housing is rough bored and face milled. The transmission case defines a plurality of transmission fluid drainage holes for draining transmission fluid from the transmission when installed in a vehicle. The housing is positioned with the fluid drainage holes below a central axis of the housing and a plurality of internal bores and faces are bored and face milled on the housing. The compressed air/oil mist is sprayed from the cutting head to cool and lubricate the boring and face milling tools. Machining chips are blown off the rough bored housing through the fluid drainage holes.
Abstract:
A numerically controlled machining center for performing work on a workpiece including a plurality of magazines holding a plurality of tools, each magazine positioned a first distance from an adjacent magazine, a plurality of spindles equal to the number of magazines and movable relative to one another independent of the positions of the magazines, the spindles movable apart from one another in a tool loading position to accommodate large magazine sizes and movable toward one another in a working position to allow the tools to work close together to minimize waste, and a table for supporting a workpiece.
Abstract:
A die chanter for a die of a joining device, a die dome adapted to the die and a method for removing a die of a joining device and a method for inserting a die into a joining device. The die has a head having upper and bottom sides, and a shaft extending from the bottom side and receivable and lockable in a dome without rotation. The shaft comprises: at least one first web forming an undercut on two sides by which the shaft is lockable in the dome by a linear inserting movement, at least one second web, the length of which is adaptable to a diameter of the dome to ensure a lateral guiding of the shaft in the dome and which is arranged between the die-head and the first web, and an ejection surface by which the die can be moved out of the dome.
Abstract:
A multi-tool adaptor which enhances overall performance of the multi-tools on which the adaptor is intended and the punch presses with which the multi-tools are desired to interface. The intermediary components relating to the functioning of the multi-tool involve one area of consideration regarding the adaptor design. Another area of consideration for the adaptor design involves the manner by which the stripper plate is operably coupled to the punch holder.
Abstract:
The invention relates to a grinding installation with a grinding machine having a head plate which is driven in a rotating and/or oscillating manner and is designed for receiving and releasably holding a grinding disk and with a device for replacing a grinding disk, which is releasably fixed on the head plate, with a stop element, against which the head plate with the grinding disk can be placed in a removal position, at least one removal finger which is adjustable between a retracted position and an engaged position, in which the removal finger engages into a recess on the head plate in the removal position, and a clamping means, through which the at least one removal finger is displaceable relative to the stop element, wherein the removal finger, for the purpose of releasing the grinding disk, comes to rest against its rear side and clamps the grinding disk on the stop element. The invention furthermore describes a corresponding method for replacing a grinding disk.
Abstract:
A machine tool for processing a workpiece comprises a processing station which has a tool receiving member in which a processing tool for processing the workpiece can be introduced and replaced, a tool store which has at least one storage space for a processing tool, a tool handling device which can be moved by a controlled drive into a tool-transfer position, a movement unit which can move the workpiece and the tool store and which can be moved by a controlled drive into any of a setup position, a processing position, and a tool changing position, a control device for the drive of the tool handling device which can define the tool-transfer position of the tool handling device, and a control device for the drive of the movement unit which can define the setup position, the processing position, and the tool changing position of the movement unit
