A machining device includes a manipulator, a base portion, and a spindle. The manipulator includes a hand device that grips a workpiece. The spindle is controlled to selectively proceed and retreat with respect to the base portion. The hand device has a workpiece gripping portion and a bottom portion, which is located on the side opposite to the workpiece gripping portion. The base portion and the bottom portion of the hand device have a positioning structure for determining the positions thereof with respect to each other.

A method for machining a workpiece which can prevent a reduction in machining accuracy and production efficiency. The method includes pressing a clamp part against a first portion of the workpiece, to clamp the workpiece in cooperation with a workpiece receiving part, causing the clamp part to move away from the first portion, to release the workpiece, which has been clamped by the clamp part, operating a robot to cause a robot hand to grasp a second portion of the workpiece, which is different from the first portion, to restrict the movement of the workpiece relative to the workpiece receiving part without a change in the posture of the workpiece, and operating a machine tool to machine the first portion while restricting the movement of the workpiece relative to the workpiece receiving part.

A method for the production of workpieces includes positioning and holding a first plate-shaped material with a gripping device in a working region of a processing station so that the first plate-shaped material is moveable relative to a workpiece support, positioning and holding a second plate-shaped material with an additional gripping device in the working region of the processing station so that the second plate-shaped material is moveable relative to the workpiece support, producing a first workpiece part from the first plate-shaped material, positioning the first workpiece part with respect to the second plate-shaped material, connecting the first workpiece part to the second plate-shaped material or to a second workpiece part produced from the second plate-shaped material, wherein the second workpiece part is at least partially processed, and finishing the at least the second workpiece part that is connected to the first workpiece part in the processing station.

A high-precision two-part flat chuck device includes: a base, a cylinder, a sliding plate, a first clamping plate and a second clamping pate. A piston rod of the cylinder is connected with the sliding plate. Precision sliding rails are arranged at two sides of the base, and two sides of the sliding plate are respectively matched with the precision sliding rails in a sliding manner. An accommodating groove is arranged in a middle part of the sliding plate. The first and second clamping plates are symmetrically distributed in the accommodating groove along a center of the sliding plate, and a spring is arranged between the first and second clamping plates. Side surfaces of the first and second clamping plates are inclined planes, and chucks matched with each other are arranged at end parts of the first and seconding clamp plates.

A machine tool, in particular a multi-spindle and/or double-spindle milling machine, comprising a machine frame, a workpiece clamping device for clamping a workpiece, an axis slide assembly which is arranged on the machine frame and is configured to linearly move the workpiece clamped on the workpiece clamping device by way of two controllable linear axes in a Y-direction and a Z-direction, and a spindle carrier assembly, which is arranged on the machine frame and has at least two tool-carrying work spindles that can be moved independently of each other in an X-direction which is perpendicular to the Y-direction and Z-direction.

A machine tool, in particular a multi-spindle and/or double-spindle milling machine, comprising a machine frame, a workpiece clamping device for clamping a workpiece, an axis slide assembly which is arranged on the machine frame and is configured to linearly move the workpiece clamped on the workpiece clamping device by way of two controllable linear axes in a Y-direction and a Z-direction, and a spindle carrier assembly, which is arranged on the machine frame and has at least two tool-carrying work spindles that can be moved independently of each other in the S1- and S2-directions which are each inclined with respect to the Y-direction and Z-direction and to one another.

A machine tool has a multiplicity of stationary tool spindles that are optionally displaceable from a retracted rest position into an extended working position are positioned at various positions in a frame-like stand which defines and comprises machining space, and has a workpiece manipulator by way of which a workpiece support is movable multi-axially in translation and preferably also in rotation. In order to create advantageous loading conditions, it proposed that a loading door is associated with at least one of the leg walls defining the machining space, and that a workpiece support holder, which is equipped with a coupling for the workpiece support, is arranged on at least one, preferably on both, loading door panel fronts.

A conveying apparatus conveys an article between a wait position and a processing position. The conveying apparatus includes a plurality of arms that sandwiches the article between leading ends of the arms located on opposite sides of the article and that is provided to enable base ends of the arms to turn so as to move the leading ends in an up-down direction, and a control apparatus that turns the arms to lift the article located at one of the wait position and the processing position and sandwiched between the arms and that moves the arms with the article kept lifted thereby to the other of the wait position and the processing position, the control apparatus turning the arms to lower and mount the article at the other of the wait position and the processing position.

An automated station (1) for the finishing of brake pads (4) comprises at least one rotary finishing tool (2) for finishing a friction layer (22) of the brake pad (4), a workhead (3) to pick, retain and release the brake pad (4), a handling unit (6) to move the workhead (3) along a programmable path comprising a pass over the rotary finishing tool (2) and a guide (5) having a mouth (27) which is passed through by the workhead (3) in order to start the finishing pass along the length of the programmable route, the guide (5) contacting the workhead (3) to define, along at least one direction (A; C), the relative position between the workhead (3) and the brake pad (4) during the finishing carried out by the rotary finishing tool (2).

A machine including: a table having a surface adapted to have a workpiece lay and move thereon, and a vise for gripping the workpiece. The machine also includes a drive system for moving the vise and workpiece a distance along the table surface, and a sensor assembly connected to the vise for measuring an amount of slip distance occurring between the vise and the workpiece. The machine also includes a control unit connected to the sensor assembly and the drive system for storing the measured slip distance and for operating the drive system and for operating to do at least one of, when a predetermined amount of slip distance is detected: sounding an alarm and stopping further movement of the workpiece, and, when a slip distance is measured, for causing the drive system to move the vise and workpiece an added distance equal to the measured slip distance.
