A toothed workpiece chamfering device having a chamfering head (2) which includes a first axis of rotation (B) for rotation of a first chamfering tool (6) and a second axis of rotation (T) for rotation of a second chamfering tool (8) wherein the first and second chamfering tools are of different types and their respective material removal methods are also different from one another. Preferably, the first and second axes of rotation are not coincident with one another and in a more preferred arrangement, the first tool axis and the second tool axis are arranged perpendicularly to one another.

A machining station especially arranged to carry out deep drill and milling operations is disclosed. The machining station now proposed presents a specific structural arrangement, enables the incorporation, contrary to already existing stations, of an axis dedicated to deep drilling, favoring the use of deep drill tools under ideal conditions, without size restriction. Accordingly, the station is comprised of an operating base, on which there lays an operating module and an arrangement module. This new arrangement for the machining station is therefore more versatile and adaptable to the specificities programmed for each part to be machined.

A machine tool includes a base, a table, a main spindle, and a trunnion unit. The table is installed on the base. A tool is mounted to the main spindle. The main spindle is caused to approach a workpiece on the table along an up-down direction. The trunnion unit is configured to rotatably hold the table on which the workpiece is placed using a rotation axis along a front-rear direction as a center. The trunnion unit is disposed movable in a right-left direction.

A method and apparatus are disclosed for assembling an end effector for an automated modular tool. A processor is programmed with data corresponding to a portion of a part surface at a designated location. A setting fixture is driven with a plurality of linear motion actuators to a selected three-dimensional location relative to an adaptor bar of the modular tool that is attached to a frame. A tool setting head is rotated with a rotary drive. A platen is tilted with at least one platen tilting motor and gear set to angularly orient the platen to correspond to an angular orientation of the portion of the part surface at the designated location. An end effector is then placed on the platen and secured with a tooling arm to the adaptor bar.

A method of operating a part cleaning machine includes removably attaching a part to a part holder. A selected first one of a plurality of tools is transferred from a tool holder to a tool chuck to perform a desired cleaning operation. The selected first one of the tools is positioned in a pre-defined tool cleaning position by moving a chuck holder along an axis on a tool positioning plane. The part is positioned in a pre-defined part cleaning position by at least one of moving a cradle along an X axis, rotating the cradle about a first cradle axis, or rotating the part holder about a second cradle axis. The desired cleaning operation is performed on the part with the selected first one of the tools, with the part in the pre-defined part cleaning position and the selected first one of the tools in the pre-defined tool cleaning position.

A part cleaning machine includes a cradle moveable along an X axis, and rotatable about a first cradle axis. A part holder is attached to the cradle, and is rotatable about a second cradle axis. A chuck holder is moveable on a tool positioning plane that is perpendicular to the X axis. A tool chuck is attached to and moveable with the chuck holder. A tool holder is moveable relative to the chuck holder along the X axis. A plurality of tools are releasably attached to the tool holder for selective attachment to the tool chuck. A machine controller is operable to control movement of the chuck holder, the tool chuck, and the tool holder to transfer a selected one of the tools between the tool chuck and the tool holder, and position an appropriate tool and the part in different positions for several different cleaning operations.

The machine tool according to the invention comprises a workpiece support (16) that is held so as to be pivotable about an A-axis. In doing so, the workpiece support (16) is held asymmetrically to the extent that it is connected only on one side to a rotary positioner (27). However, both sides are held on the slides (25, 26), each being connected to a linear drive (30, 34). The slide (26) without rotary drive runs only on one guide rail (24), whereas the slide (25) with the rotary positioner (27) runs on two guide rails (22, 23). In view of the Z-acceleration, the workpiece support (16) is guided symmetrically. The result is a compact and still highly robust machine concept.

A control system of a machine tool includes an analysis device, the analysis device includes acquisition portions which acquire chronological speed control data when a work is machined and which acquire spatial machined surface measurement data after the machining of the work, a data-associating processing portion which associates the speed control data and the machined surface measurement data with each other, a machined surface failure detection portion which detects a failure depth of a failure location on the machined surface of the work and an identification portion which identifies the control data of the failure location corresponding to the machined surface measurement data of the failure location so as to identify a failure depth corresponding to the control data of the failure location and the numerical control device corrects the control data based on the control data of the failure location and the corresponding failure depth.

An error identification method includes a tool sensor position acquisition stage, a reference block position acquisition stage, a relative position calculation stage, a reference tool position acquisition stage, a position measurement sensor measurement stage, a length compensation value calculation stage, a diameter compensation value acquisition stage, a position measurement stage, a position compensation stage, and a geometric error identification stage. The diameter compensation value acquisition stage acquires a radial direction compensation value of the position measurement sensor with the measured jig. The position measurement stage indexes the rotation axis to a plurality of any given angles and measures respective positions of the measured jig. The position compensation stage compensates the position measurement value at the position measurement stage using the length direction compensation value and the radial direction compensation value. The geometric error identification stage identifies the geometric error from the plurality of position measurement values.

A lathe includes a lathe-side chuck that holds a workpiece with the workpiece directed toward or facing a front side, a main spindle that rotates around an axis, and a tool that machines the workpiece. A machining center includes a rotary tool that rotates around an axis in the horizontal direction and an MC-side chuck that holds the workpiece and is able to turn between at least a workpiece pass/receive position in which the workpiece is directed toward or facing the front side and a machining position in which the workpiece is directed toward or facing the rotary tool. A loader includes a guide rail extending above the lathe-side chucks, and MC-side chuck along the horizontal direction and a loader head that holds the workpiece and carries the workpiece between at least the lathe-side chucks, and MC-side chuck by moving along the guide rail.
