A machining tool includes a light irradiator, a cover, and a light blocking filter. The light irradiator is to irradiate a workpiece to process the workpiece. The cover covers the light irradiator and the workpiece in the cover. The light blocking filter is configured to change light transmissivity of the light blocking filter in accordance with light from an inside of the cover, which the light blocking filter receives.

Composite processing machine, machining tool, and composite processing method

A composite machining machine includes a first machining head, a second machining head, a workpiece holder, a cover, and a frame. The first machining head is movable in a first region to perform additive manufacturing on the workpiece in a second region. The second machining head is movable in the second region to perform cutting on the workpiece. The workpiece holder holds the workpiece in the second region. The cover covers the first region. The frame includes two columns and a beam member coupling the columns. The cover includes a region definition member openable at least partially. The region definition member defines the second region. The first machining head is movable in a guided manner in a range between the columns. The beam member is disposed so that the predetermined range lies inside the first region, and outside and above the second region.

A friction stir welding tool includes a stir pin, a pin holder, and a housing. The pin holder supports the stir pin to rotate with the stir pin around a rotation axis of the stir pin and has a front portion and a rear portion opposite to the front portion along the rotation axis. A tip end of the stir pin projects from the front portion. The housing houses the pin holder such that the pin holder is rotatable relatively to the housing. The tip end of the stir pin projects from the housing. The housing includes an engaging portion engageable with a spindle frame of a machining head such that the rear portion of the pin holder is attached to a rotation spindle of the machining head to rotate the pin holder. The rotation spindle is rotatable relatively to the spindle frame.

A slip ring is accommodated in a ram. The slip ring includes a fixed portionhaving a feed element connected to a power source and a movable portionelectrically connected to the feed element. The movable portionincludes a contactfor supplying electricity to a spindle unitand an electric device of a spindle head. After determining the position of a saddlein a Y-axis direction and the position of a table in an X-axis direction, the position of the spindle headabout a B-axis is determined. Then, the ramis moved along the Z-axis direction with the spindle unitrevolved about the C-axis, and, with a non-rotational cutting toolattached to the spindle unit, a hole is bored in a workpiece W on the table.

The object of the invention is to provide an inverted vertical lathe comprising a device for replacing collets automatically, and having a detector for detecting that the collet has been gripped correctly. A chuckmounted on a headstockgrips a colletin a replaceable manner via a tapered boreprovided to the end thereof. A collet end face eccentricity detectorcomprises a detecting member (sensor)fixed to the end of an arm. The detecting memberdetects the eccentricity of the end faceof the colletin a contactless manner. A variation pattern of the eccentricity occurring when each colletis gripped correctly by the chuckon the main spindle is detected in advance, and this pattern is compared with the variation pattern of the eccentricity detected by the present detection, and thus, whether or not the collet has been gripped correctly is detected.

A complex machine tool has a single frame having a chip collecting space at a center portion thereof, first and second spindle stocks on the frame, relatively free to move and drive in a Z axis direction and holding the chip collecting space therebetween, workpiece spindles on the spindle stocks free to rotate and drive and facing each other, and tool rests. The tool rests have turrets and can assume various kinds of movement. Complicated and varied types of machining can be performed combining the rotation control of the workpiece spindles and the spindle stocks.

In a machine tool having plural coordinate systems and having controlled objects controlled on the basis of those coordinate systems, a coordinate system data memory storing dimensional information corresponding to each coordinate system as a coordinate system data is provided. A coordinate relation memory storing the coordinate position relation information by which the position relation among plural coordinate system is specified is also provided. If the controlled object corresponding to each coordinate system is driven, the coordinate system data is read from the coordinate system data memory when the coordinate system data belonging to the coordinate system except the coordinate system in which the controlled object is driven is needed. The read coordinate system data is converted from the coordinate system to which the corresponding coordinate system data belongs into the other coordinate system to which the controlled object belongs on the basis of the coordinate position relation information in the coordinate relation memory, and the controlled object is controlled on the basis of the converted coordinate system data.
