An apparatus can deliver a static cutting tool to a position located inside a workpiece to be machined. The cutting tool can be used for machining at least one surface inside of the workpiece. The cutting tool is operable in combination with an electronic controlled machine tool having at least one axially movable drive/support spindle. A cutting tool body can have at least one cutter and an aperture adapted for receiving the axially movable drive/support spindle of the electronic controlled machine tool. A movable carriage can be used for releasibly supporting the tool body and for transporting the tool body between a home position, where the tool body is spaced from coaxial alignment with the axially movable drive/support spindle of the electronic controlled machine tool, and a ready position, where the aperture of the tool body is in a coaxially aligned position with respect to the axially movable drive/support spindle of the electronic controlled machine tool. The carriage can be used for transferring support of the cutting tool body with respect to the movable drive/support spindle of the electronic controlled machine tool when the carriage is in the ready position.
摘要:
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 device for machining grooves (20) in a cylindrical bore emerging at the end of a master cylinder. The device includes a cylindrical tool (44) with a peripheral set of teeth (45) formed thereon by a series of cutting teeth (46). The tool (44) is inserted axially in the bore of the master cylinder (1) through a tool-holder shaft (39) that is initially driven in an orbital movement and later held immobile in rotation about its axis (42) and the master cylinder 1) and the tool-holder shaft (39) are thereafter separated from each other by axial translation.
摘要:
A debris removal apparatus for a milling machine. In one embodiment, the debris removal apparatus includes a hollow, cylindrical suction member that attaches to a tool shaft which holds an end mill to rotate with the tool shaft. The debris removal apparatus further includes a nonrotating canister that applies a suction force to the suction member. The suction member is dimensioned to fit within a hole being cut by the end mill as the end mill is fed into the hole, and to extract debris created by the end mill via the suction force.
摘要:
A tool (100) for working the internal bore of a tube comprises a motor (10), having a housing with a rotary output; a housing sleeve (14a) and shaft (22); a first bearing housing (16), having a rotatably journalled first spindle (102), mounted on the housing sleeve; and an end sleeve and shaft connected to a tool head. The motor output drives, along a common axis (1), the housing shaft, first bearing spindle, end shaft and tool head. A change mechanism (56,58) is in the tool head to change direction of said drive to transverse said common axis. An output (60) is adapted to receive a tool bit. Gauge means (18,18′) is disposed on said tool head and is adapted, in use, to bear against the bore of the tube and maintain the tool head located radially with respect to the tube axis; and support means (24,24′) is disposed on one or more of said housing shaft, first bearing housing and end sleeve adapted, in use, to bear against the bore of the tube and support the tool. A long length of tool can work the inside of long tubes.
摘要:
In order to produce a connecting means for connecting a first component and a second component and especially for connecting furniture parts or machine parts which will enable two components consisting of a multiplicity of materials to be securely connected to one another without giving rise to the danger of damaging the two components during the assembly process, wherein the device comprises a first connecting element that it arranged on the first component in the connected state of the components and a second connecting element that is arranged on the second component in the connected state of the components, it is proposed that at least one of the connecting elements should comprise a non self-cutting holding projection which has a curved support surface that is in the form of an arc of a circle in longitudinal section, wherein the holding projection can be inserted into a groove which is provided in one of the components and has a curved undercut surface that is in the form of an arc of a circle in longitudinal section.
