The mounting surface is closer to a first surface than an upper surface of the fixed table.

A rotary table apparatus includes: a rotary table casing; a face plate which is pivotally supported by the rotary table casing and which can freely rotate; and a joint and a free tube into which a power cable is inserted, the power cable supplying power to rotate the face plate, and an adaptor whose mounting direction with respect to the rotary table casing can be changed and which can be attached to and detached from the rotary table casing is placed between the rotary table casing and the joint.

A method includes applying a force to elastically deform at least a portion of a superalloy turbine blade from a relaxed, initial position to an elastically deformed position. The at least a portion of the superalloy turbine blade has a curvature in the elastically deformed position not present in the relaxed, initial position. A hole is drilled generally span-wise through the at least a portion of the superalloy turbine blade in the elastically deformed position, and when the force is released, the superalloy turbine blade returns to the relaxed, initial position and the hole takes on a hole curvature within the at least a portion of the superalloy turbine blade.

A multi-axis alignment tool including: a main body, a primary base, a puck, a first puck adjuster, a second puck adjuster, a puck retainer, a secondary base, a first pivot pin, a second pivot pin, a pivot block, a clamp head, an adjustment pin, a lock-down spacer, a first clamp finger, and a second clamp finger, wherein the multi-axis alignment tool is configured for to at least one of clamp, align, and position a work part in three axes.

A gripping device configured as a robot tool or a robot hand includes two gripper fingers rotationally coupled to each other by a joint. The gripper fingers are pivotable about a rotational axis between a gripping position and a release position, the rotational axis being defined by the joint. An angle between the gripper fingers about the rotational axis is larger in the gripping position than in the release position. The gripper fingers are configured to reach through a through-hole in an object to be gripped from a first side of the object. The gripper fingers have an end piece at a distal end thereof, the end piece being configured to engage behind the object at a second side of the object opposite the first side along a length axis of the gripper fingers. The joint is fixed to a joint support extending from a main body.

A method of manufacturing sharp bodies by wire electro-erosion includes providing a wire electro-erosion machine and a fixture mounted to the wire electro-erosion machine so that a portion thereof can rotate about a rotation axis which is transverse to a longitudinal extension of the cutting wire.
