A high-precision turning device. The device has a base plate, a base, a support A, wherein a groove is formed in the center of the bottom surface of the base, and a lead screw passes through the groove; symmetrical T-shaped annular grooves are formed in two sides of the interior of the base, two symmetrical T-shaped annular columns are arranged on the lower end face of a turning block, and the T-shaped annular columns can be inserted into the T-shaped annular grooves; and the structure of a central position of the lower end face of the turning block is annular teeth, and the annular teeth are meshed with the lead screw. A servomotor drives the lead screw to rotate, and by virtue of meshing matching of the annular teeth and the lead screw, the turning block can turn along the centers of the T-shaped annular grooves in the base.

A mobile machine tool for segmentally machining, in situ, a component, in particular a component of a turbine, which is rotatable about an axis of rotation. The machine tool has a main body, a support element which is held on the main body so as to be movable about a C-axis along a circular-arc-shaped guide path, and a tool module which is held on the support element and is designed to receive a tool. The tool module is located on the support element so as to be linearly movable. A method segmentally machines, in-situ, a component which is mounted in a stationary body so as to be rotatable about an axis of rotation.

The present invention discloses a multi-degree-of-freedom numerical control turntable including: a B-shaft rotating assembly; a C1-shaft workbench swing assembly; a C2-shaft workbench rotating assembly; and an S-shaft workbench movement assembly. The B-shaft rotating assembly includes a rotating connection land and a B-shaft power control mechanism; the C2-shaft workbench rotating assembly includes a movement base, a workbench and a C2-shaft power control mechanism; the S-shaft workbench movement assembly includes a swing base and an S-shaft power control mechanism; and the C1-shaft workbench swing assembly includes a swing arm and a C1-shaft power control mechanism, with the C1-shaft line intersecting the B-shaft line. The S-shaft power control mechanism can drive the movement base to move along an S-shaft line on the swing base to cause a region to be machined of a workpiece to approach the intersection point of the C1-shaft line and the B-shaft line. The present invention adds the C1-shaft and S-shaft, so that when the cutting edge point participates in the motion, the coordinate change of the linear shaft is smaller, the compensation range of the linear shaft is smaller, the machining efficiency is higher, and the surface quality and machining accuracy are less affected by the accuracy of the linear shaft.

A key duplicating machine includes: a support structure, a front operational area which is accessible by the operator and which is removably covered and separated, at least partially, from the external environment by a covering and/or protection crankcase movable with respect to said structure of support. At least one key cutter and/or another cutting element, and at least one terminal (12) for locking a key, are housed in the front operational area, a rear containment area, covered and separated from the external environment by a casing mechanically fixed to the support structure, and a control and command unit having a mechanism for moving said crankcase for covering and/or protecting the front operational area, the crankcase being configured to be mounted on a fixed structure of the duplicating machine so as to be able to be moved with respect to the fixed structure.

A method of machining a tooth flank of a gear with a gear machining tool. The method comprises rotating the tool and bringing the tool and the tooth flank into contact. Relative movements are provided between the tool and the gear to traverse the tool across the tooth flank along a path whereby the path produces a tooth flank geometry of a form which, when brought into mesh with a mating tooth flank under no load or light load to form a tooth pair, provides a motion graph curve comprising a sinusoidal portion (62, 89, 91, 90, 63) and a parabolic portion (92).

A machining system comprises a machining device that machines a workpiece, a set-up station with which pallet workpiece attachment/detachment is carried out, and a pallet conveyance device that conveys the pallet between the machining device and the set-up station. A partially cylindrical operator door, which can rotate around a set-up table on which the pallet is mounted, includes a partially cylindrical outer door and a partially cylindrical inner door which rotate following coaxial circular trajectories of different radii. The set-up station is provided with an interlocking mechanism that causes the outer door and the inner door to rotate in an interlocked manner so that a shielded state is constantly maintained between the operator side and the pallet conveyance device side.

A method and apparatus are disclosed for assembling an end effector for an automated modular tool. A processor is programmed with data corresponding to a portion of a part surface at a designated location. A setting fixture is driven with a plurality of linear motion actuators to a selected three-dimensional location relative to an adaptor bar of the modular tool that is attached to a frame. A tool setting head is rotated with a rotary drive. A platen is tilted with at least one platen tilting motor and gear set to angularly orient the platen to correspond to an angular orientation of the portion of the part surface at the designated location. An end effector is then placed on the platen and secured with a tooling arm to the adaptor bar.
