Machine tool simplifying maintenance, reducing manufacturing costs, and enabling high precision machining. The machine tool is equipped with: a bed furnished with a rectangular base, right and left sidewalls provided standing either side of the base, and a rear sidewall provided standing along the back of the base; a table disposed in the space surrounded by the three sidewalls; a first saddle shaped in the form of a rectangular frame shape, provided free to shift back and forth supported on the tops of the left and right sidewalls; a second saddle penetrated by a perpendicular through-hole and arranged free to shift sideways inside the first saddle frame; and a spindle head arranged free to shift perpendicularly inside the through-hole in the second saddle; and a main spindle arranged over the table and supported by the spindle head free to rotate centered on its axis.

The present invention provides a tool changer of a machine tool capable of suppressing cost increase and preventing size increase of the machine when a tool magazine is mounted. In a tool changer of a machine tool provided with a pallet change mechanism 10 in which a machining-side pallet 11 disposed on a machining area A side and a standby-side pallet 12 disposed on a standby area B side are turned around a turn shaft 14 by a turning member 13 to be automatically changed, a tool magazine 28 holding a plurality of tools T1 to T4 is disposed between the machining-side pallet 11 and the standby-side pallet 12 in the turning member 13 and the tool magazine 28 is turned by the turning member 13 so that the tools T1 to T4 face a spindle 5 disposed on the machining area A side.

A method for loading and unloading a machining machine for machining boards that includes for loading the machining machine, the changing table is loaded with a board to be machined, whereby the board is separated from the first storage place and is deposited on a changing table. The changing table is conveyed together with the board to the machining machine. For unloading the machining machine, the changing table is conveyed together with a machined board to the second storage place and is then unloaded, wherein the machined board is separated from the changing table and deposited on the second storage place, wherein the unloading of the changing table includes conveying the changing table and the machined board to an unloading place in an area above the second storage place and the machined board is separated from the changing table at the unloading place.

The invention relates to a method for tooth-machining of workpieces (3), especially gear wheels, comprising milling, deburring by hobbing and integrated secondary deburring. The method proceeds on a machine tool (1) having two workpiece spindles (11, 12) which may exchange places. A workpiece (3) is mounted on a first workpiece spindle (11), followed by the workpiece spindles (11, 12) exchanging places, followed by pre-milling and, where applicable, cutting (=deburring by shaving) of the workpiece (3), followed by a further exchange of places, followed by chamfering and cutting of the workpiece (3), followed by a further exchange of places, followed by a finish-milling of the workpiece (3), followed by a further exchange of places, followed by a workpiece change. At the same time, the same procedure takes place on the second workpiece spindle (12), staggered in time by an exchange of places of the workpiece spindles (11, 12). With the method according to the invention, well-deburred toothed workpieces (3) may be produced quickly and at low cost.

A machine tool is provided with: a rotating table apparatus that has a table for holding a workpiece, and that rotates the table based on a drive force that has been input; a processing area for processing the workpiece, the rotating table apparatus being carried into and out from the processing area; and a drive source for inputting the drive force when connected to the rotating table apparatus, the drive source being provided in the processing area such that the drive source can be disconnected from the rotating table apparatus.

The present invention relates to a semiconductor processing system that employs infrared-based thermopile detector for process control, by analyzing a material of interest, based on absorption of infrared light at a characteristic wavelength by such material. In one embodiment, an infrared light beam is transmitted through a linear transmission path from an infrared light source through a sampling region containing material of interest into the thermopile detector. The linear transmission path reduces the risk of signal loss during transmission of the infrared light. The transmission path of the infrared light may comprise a highly smooth and reflective inner surface for minimizing such signal loss during transmission.

The invention relates to a machine tool for machining workpieces (P), wherein the machine tool (10) has a first spindle assembly (21) and at least one second spindle assembly (22) each having at least two working spindles (24) which are arranged in a common spindle housing (26, 126) and on which in each case a machining tool (25) for workpiece machining is arrangeable, wherein the machine tool (10) has a workpiece holding device (50) for holding workpieces (P) for the purpose of workpiece machining by way of the machining tools (25), wherein the machine tool (10) has a guide arrangement (30) for the relative positioning of the workpiece holding device (50) holding the workpieces (P) and the first and the at least one second spindle assembly (22) for workpiece machining. In the machine tool (10), provision is made for the first spindle assembly (21) to be guided on a first spindle-assembly guide (31) of the guide arrangement (30) and for the at least one second spindle assembly (22) to be guided on a second spindle-assembly guide (32), separate from the first spindle-assembly guide (31), of the guide arrangement (30), such that the spindle assemblies are movable independently of one another into a working region (A), in which the workpieces (P) are provided for workpiece machining by the workpiece holding device (50), and a tool changing region (W) provided for changing machining tools (25) on the working spindles (24).
