A chamfering device includes: a main body including, at a proximal end side thereof, a shank to be attached to a main shaft of a machine tool, the main body including, at a distal end side thereof, a shaft portion extending in a rotational axis direction; a movable body whose proximal end portion is mounted to the shaft portion, the movable body being configured to rotate together with the shaft portion and be movable in the rotational axis direction; an urging member configured to urge the movable body in a direction toward the distal end of the main body; a chamfering tool mounted to a distal end portion of the movable body and configured to rotate together with the movable body to perform chamfering on an edge portion of a workpiece; and a following member mounted to the movable body such that a position of the following member relative to the movable body in the rotational axis direction is invariable and the following member is rotatable relative to the movable body, the following member being configured such that a distal end thereof comes into contact with a surface of the workpiece.

A milling device for machining a slot into an inner surface of a casing for a gas turbine engine. The milling device includes a frame assembly including multiple structural guides configured to engage structural features on the inner surface of the casing to maintain an axial position of the milling device relative to a longitudinal axis of the casing. The milling device also includes a milling cutter coupled to the frame assembly. The milling device is configured to be displaced in a circumferential direction relative to the longitudinal axis to machine the slot, via the milling cutter, along the inner surface of the casing in the circumferential direction.

This disclosure relates to a tool guide for a tool that shapes a workpiece. The tool guide may include a body having a contact surface configured to contact a surface of a workpiece, a tool holder positioned within the body and configured to hold a machining tool having a tool bit, the tool holder holding the machining tool in a predetermined orientation relative to the workpiece, a guide element attached to the body configured to engage a surface feature of the workpiece, and an upper opening and a lower opening in the body configured to allow the tool bit to extend beyond the contact surface and operate to remove a portion of the workpiece.

A machining system includes a machining unit and a moving apparatus configured to move the machining unit. The machining unit includes a rotating tool for rotating about an axis in a vertical direction, an upper surface abutting member configured to be abutted against an upper surface of a work, an end face abutting member configured to be abutted against an end face of the work between an upper edge and an lower edge of the work, and a vertical moving unit configured to change a position of the upper surface abutting member in the vertical direction with respect to the rotating tool. The rotating tool includes a machining portion main body, a first machining portion provided on a lower side of the machining portion main body, and a second machining portion provided on an upper side of the machining portion main body.

An apparatus for guiding a rotary tool along a work piece corner edge formed by the intersection of two orthogonal planar surfaces, has a corner guide formed by two orthogonal planar components and defining a longitudinal axis from back to front. An adjustable tool holder assembly is affixed to the corner guide, includes a tool holder, and is configured to independently adjust a tool holder longitudinal position along the corner guide, a radial position of the tool holder relative to the corner guide, and an angular orientation of the tool holder rotating in a transverse plane orthogonal to the longitudinal axis.

Device for machining an end of an elementary panel for its subsequent friction stir welding, the elementary panel comprising a metal body defining two opposite faces, the machining device comprising a chassis, at least two guiding members configured to guide a first face of the elementary panel, at least one machining tool mounted on the chassis, the machining tool being positioned between the two guiding members and at least one pressure member mounted on the chassis and configured to exert a pressure on a second face of the elementary panel so as to press the elementary panel against the guiding members along the horizontal reference direction.

A cam for use in trimming earing from an open end of an article following at least one forming process. The cam includes a cam profile for actuating a cam follower to which the article is coupled. The cam profile includes a generally sloped rising portion, a generally sloped retracting portion, and a working portion bridging the rising portion and the retracting portion. The working portion includes generally sloped sections separated by at least one recess or dwell.

A method and apparatus for the refurbishment and repowering of wind turbines through the extension of existing installed blades so that they can catch more wind energy and therefore enable an increase in the overall average power output of the wind turbine.

An automatic milling machine mills a gasket. The automatic milling machine controls the position of a cutter head relative a table. The automatic milling machine rotates the gasket with a motor. Parameters of the motor are monitored to determine the amount of rotation of the gasket.

An edge break apparatus including a frame having a first workpiece interface surface, a second workpiece interface surface arranged relative to the first workpiece interface surface so as to form a predetermined angle between the first workpiece surface and the second workpiece surface, and a first aperture extending through the frame so as to intersect the predetermined angle, and an edge break member extending through and interfaced with the first aperture so as to adjustably define a cutting depth of the edge break member relative to an apex of the predetermined angle.
