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.

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 tool for removing burrs/flash from a work piece includes a linear body having a cutter/abrasive end and an opposite shank end. The shank end is adapted for attachment to a rotary power source. At least one bushing is secured to the linear body, the bushing allowing rotation of the tool there within while an outer portion of the bushing remains stationary.

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 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.

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.

The invention relates to a finishing device for removing the weld bead generated during welding of a window or door frame or frame section at the mitered surfaces, wherein the finishing device comprises a support surface for the frame or frame section and a processing arm for supporting a tool holder, and the processing arm consists of a plurality of arm elements that move in hinged fashion relative to one another but can also be fixed in place, wherein the tool holder comprises at least two cutting tools driven by a rotational drive, said tools rotating about a tool axis and at least one tool laterally next to the blade of the tool, contact sides.

A portable manual vertical milling key duplicating machine comprising a body, a main axis component, a guide component, a clamping component, a feeding component, a power storage unit, a display unit and an electric control unit. This solution provides a pre-positioned precise guide mechanism and an adjustable handrail and is capable of improving the precision of key processing in multiple aspects and increasing stability during key processing. It has a compact structure with an upper/lower separate two-way sliding table configuration, thereby substantially reducing the machine size, and the body is divided into three areas, thereby ensuring good protection.

A method of machining an attachment flange of an aircraft turbomachine case, the method also including a system to machine the two opposite surfaces of the flange, and including a shape follower machining module, this module being designed to follow the shape of the flange and including a first structure equipped with a first machining tool, and a second structure equipped with a second machining tool, the flange fitting between the structures such that its two opposite surfaces are machined by tools, the module also including shape follower elements carried by the structures; and a device to drive movement of the machining module along a circumferential direction of the flange.

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.
