The operational control method includes determining whether an abnormality has occurred in the cutting-tool during a processing or not, determining whether a simultaneous processing in which at least two or more of the tool holders perform the processings to an identical workpiece is being performed or not and whether the cutting-tool having the detected abnormality is the cutting-tool that is performing the simultaneous processing or not when the abnormality is detected, and causing the tool holder with the cutting-tool having the detected abnormality to take an abnormality avoidance operation and another of the tool holders to take a response operation based on a determination result at the determining of the simultaneous processing.

A device is provided for machining rod-shaped workpieces such as window profiles or door profiles. The workpieces can be moved in a horizontal plane in a Z direction by a transport device. A machining device with tools is provided in a plane arranged substantially vertically to the direction of movement of the workpieces, which machining device is spatially oriented in the vertical plane in relation to the workpiece. The machining device includes an open arc arranged in the vertical plane to the workpiece, the arc being mounted to rotate about the workpiece in the Z axis as an open flat ring.

A machine tool includes a lower tool post for holding a cutting tool, a tool main spindle for holding a cutting tool, a storage unit capable of storing the cutting tool, an exchange mechanism for exchanging the cutting tools between the tool main spindle and the storage unit, an inside robot for exchanging the cutting tools between the lower tool post and the tool main spindle, and a controller. The controller performs control such that the cutting tools are exchanged between the lower tool post and the storage unit via the inside robot, the tool main spindle, and the exchange mechanism.

The invention relates to a device (1) for drilling holes in the axial and radial direction of a blade root of a wind turbine, wherein the device comprises: a first base (2), which is to be stationary positioned on the ground; a second base (3), which is moveably mounted to the first base (2) and movable along a first direction; first drive means for positioning the second base (3) along the first direction; a rotary arm (4), which is pivotally mounted to the second base (3) around a main axis (5); second drive means for rotating the rotary arm (4) around the main axis (5); wherein the rotary arm (4) comprises a guide track (7) which extends from a first outer end to a second outer end of the rotary arm (4) thereby passing the main axis (5); first drilling means (8) moveably arranged on the guide track (7), comprising a first drilling tool (8-1) for drilling holes in a second direction (8-2), which second direction (8-2) is perpendicular to the main axis (5) andthird drive means for positioning the first drilling means (8) along the guide track (7); second drilling means (9) mounted on the rotary arm (4), comprising a second drilling tool for drilling holes in a third direction (9-2), which third direction (9-2) is parallel to the main axis (5).

A straddle-type steel section processing device of multiple saddles is disclosed, which comprises: a machine unit, a holding unit, a Z-axis direction processing unit, a pair of Y-axis direction processing units, a Y-axis direction guiderail unit and a Y-axis direction driving unit. In an embodiment, the Y-axis direction processing units are arranged respectively at the two sides of the Z-axis direction processing unit while allowing each to slide in a Y-axis direction as each Y-axis direction processing unit is further being mounted on a crossbeam of a base fitted on the machine unit. By sildably mounting the side saddles of the Y-axis direction processing unit on an end surface of the crossbeam, not only a desire condition of stable positioning can be achieved, but also the processing accuracy is enhanced.
