A processing apparatus and a processing method with which an object-to-be-cut is processed, and a high-precision superconducting acceleration cavity can be formed. The processing apparatus forming a half cell by processing a hollow workpiece, and is provided with a securing jig, a rotational drive portion rotating the securing jig, and a cutting tool. The securing jig having a plurality of members, when cutting a first portion-to-be-cut of the workpiece, the plurality of members are combined in a first pattern so that the first portion-to-be-cut is exposed, when cutting a second portion-to-be-cut of the workpiece, the plurality of members are combined in a second pattern so that the second portion-to-be-cut is exposed, and the combination of the plurality of members is changed from the first pattern to the second pattern without removing the workpiece.

An additive manufacturing head includes: a nozzle configured to discharge material powder; a rotary member connected with the nozzle, including a first material powder passage formed in the rotary member to direct the material powder to the nozzle, and configured to rotate to cause the nozzle to move in the circumferential direction about a laser beam emitted toward the workpiece; and a stationary member including a second material powder passage which is formed in the stationary member and into which the material powder is introduced, the stationary member being disposed directly beside the rotary member in the direction of the rotational axis of the rotary member. A third material powder passage communicating with the first material powder passage and the second material powder passage and extending annularly about the rotational axis of the rotary member is formed between the stationary member and the rotary member. Accordingly, an additive manufacturing head that implements a mechanism configured simply to feed material powder to an infinitely revolving nozzle is provided.

A method and a device for machining a workpiece rotating about a rotational axis. The machining point moves along the cutting edge of a cutting edge plane and the surface to be machined in a rolling movement on an advancement plane not intersected by the rotational axis. A pivot drive implements a large enough pivot angle so that a first workpiece surface is machined by a machining point moving along the first cutting edge in a first machining step. In a second machining step, a second workpiece surface is machined, wherein the machining point moves along the second cutting edge and the second workpiece surface. The cutting edge has a curvature radius smaller than the distance from the pivot axis of the holder to the cutting edge. The holder can additionally be displaced on the advancement plane with a movement component in a direction transverse to the rotational axis.

A low density substrate material for reflecting optics. The substrate material is a magnesium alloy or composite material that is capable of being finished by diamond turning to form an optically smooth surface with low root-mean-square roughness. The finish quality of the diamond-turned surface is sufficiently good to permit use of the magnesium material as a substrate for a reflecting optic without further processing. The magnesium substrate material contains at least 80 wt % Mg and may also include Al, Si and/or other elements. The density of the magnesium substrate material is much lower than the density of current Al alloy substrate materials.

A lathe includes a machine support, a working table positioned on the machine support, a rotating driver, a moving device, and a feeding device. The rotating driver rotates the work table. The moving device includes at least one cross beam, at least one first driving mechanism, and at least one second driving mechanism. The cross beam is movably positioned on the machine support above the working table. The feeding device is movably positioned on the at least one cross beam, and includes a feeding driving mechanism and a cutter. The first driving mechanism drives the cross beam to move along a first direction, and the second driving mechanism drives the feeding device to move along a second direction at about ninety degrees from the first direction. The feeding mechanism drives the cutter to move backwards and forwards along a third direction perpendicular to the first and second direction.
