A gripping machine for an article includes a machine frame, first and second drive means associated with the machine frame, a support platform of the article, movable with respect to the machine frame by the first drive means along a direction of displacement, and holding members, arranged about the direction of displacement to delimit therebetween a gripping plane or space of the article, at least one holding member being movable radially by the second drive means between a holding configuration and a release configuration of the article, and vice versa. Electronic control means control the first drive means so that the support platform is located at one or more predefined axial positions and the second drive means so that, in the holding configuration, at least one holding member is moved continuously towards the article to actively clamp the article.

A pressure applying system using a modular vise having a fixed base and an adjustable pusher assembly. The modular vise utilizes a bi-directional worm screw to apply a linear force from the pusher assembly to the working member relative to the fixed base. The fixed base is secured and located from below a bottom surface of the fixed base.

A transmission arrangement for energy and/or signal transmission between a control unit of a machine tool and at least one electronic component, in particular for use in a machining center or a turning and/or milling center. The transmission arrangement is configured to transmit energy and/or signals between electronic components arranged on a pallet and a control unit of a machine tool. The method shows a procedure for automated machining of a workpiece by means of a machine tool, in particular when electronic components are arranged on a pallet on which the workpiece is clamped.

A machining device for scraping a workpiece is provided. The machining device includes: a drive unit for driving a scraper; a first detection unit for detecting the position of the scraper; a second detection unit for detecting the machining force of the scraper with respect to the workpiece; a first acquisition unit for acquiring information relating to displacement of the scraper; a second acquisition unit for acquiring information relating to the machining force of the scraper; and a control unit for driving the drive unit based on the information relating to the displacement of the scraper by the first acquisition unit and the information relating to the machining force of the scraper acquired by the second acquisition unit, so the displacement and the machining force of the scraper satisfy a prescribed relationship. A control device and a control method for the machining device are also provided.

A control device acquires first detection values related to control of a motor at a plurality of positions on a first path by moving an object or a tool along the first path with the object and the tool prevented from coming into contact with each other, acquires second detection values related to the control of the motor at a plurality of positions on a second path substantially parallel to the first path by moving the object or the tool along the second path to bring the object and the tool into contact with each other, derives a difference value between the first detection value and the second detection value acquired at each of corresponding positions on the first path and the second path, and detects contact between the tool and the object based on changes in the difference values derived for the plurality of positions.

A load measuring arrangement for a collet assembly is provided. The load measuring arrangement includes a housing having a pocket which includes a first portion and a second portion. The load measuring arrangement further includes a first clamp member having a first groove and a second clamp member having a second groove. The first clamp member and the second clamp member are disposed in the first portion such that the first groove and the second groove together forms a receiving portion. A load measurement device is disposed next to the second clamp member in the second portion such that a load-responsive portion of the load measurement device is configured to be in contact with the second clamp member. The second clamp member is pushed outwards against the load-responsive portion when the receiving portion receives the collet assembly.

A wheel fixture is disclosed. A main shaft drives a first positioning pull rod on a chuck body to extend and contract in the radial direction via a tightening screw, a clamping jaw is at a position within the travel range of extension and contraction, a wheel is positioned and clamped by the fixture, airtight support blocks are pressed down by the wheel and flush with the support plane of the clamping jaw, at this time, airtight ejector rods press second O rings to prevent air from flowing out of the airtight detection position, a detection system of a machine tool detects a preset air pressure value which indicate that the wheel has been placed correctly, and if the wheel is not placed correctly on the fixture, the machine tool will alarm through the detected pressure feedback.

A workpiece rotating apparatus including a first rotary positioner and a second rotary positioner which are arranged to face each other in a direction along a substantially horizontal rotation axis, which hold, respectively, one end portion and the other end portion of a long workpiece, and which can rotate the workpiece around the rotation axis, a linear motor which linearly moves the second rotary positioner in a direction along the rotation axis, and a motor controller which controls the linear motor to adjust a position of the second rotary positioner in a direction along the rotation axis, and the motor controller controls the linear motor so that magnitude of force acting on the linear motor from the other end portion of the workpiece via the second rotary positioner becomes equal to or smaller than a predetermined threshold.

A main spindle device for a machine tool that checks the seating of a tool holder using compressed air, wherein the main spindle device for a machine tool comprises: a main spindle that has a distal end face in close contact with a flange end of the tool holder; an annular recess that is formed on the distal end face of the main spindle so as to be covered by the flange end of the tool holder; an air supply flow channel that is linked to the annular recess and that supplies compressed air to the annular recess; a compressed air source that supplies air to the air supply flow channel; and a pressure detector that detects the pressure of the compressed air in the air supply flow channel. The annular recess has a first section and a second section that is deeper than the first section, and the air supply flow channel is opened to the second section.
