A coupler is positioned between the shaft and the endmill cutter. A positioning slide is housed within the base frame and a coupler frame and a first gear are fastened to the positioning slide. A second gear is adjacent to the first gear, the second gear having a set of first teeth and a set of second teeth positioned opposite the set of first teeth. The set of first teeth and the set of second teeth are separated by a gap.

A portable computer numerical control (CNC) machine is described. The CNC machine has an X-axis, a Y-axis, and a Z-axis, and comprises: a machine head, a base comprising a pair of X-axis guiding rails; a connecting beam and at least one Y-axis guide rail; a sub-assembly having a platform and at least one Z-axis guide rail on the platform; and a tool assembly secured to the platform of the sub-assembly, as well as corresponding X-Axis, Y-Axis and Z-axis clamps to allow the machine head to move along the X, Y, Z axes. The tool assembly of the CNC machine further allows the machine head to rotate about an axis that is perpendicular to the Z-axis.

In one example, an on-wing method for in-situ cutting on a wing-to-fuselage attachment includes attaching a first mount plate having a first linear bearing to provide movement in a first linear direction relative to the first mount plate, attaching a second mount plate having a second linear bearing to provide movement in a second linear direction relative to the second mount plate, attaching a tool mounting member to the second linear bearing to move with the second linear bearing, attaching a cutter to the tool mounting member to be adjustable relative to the second linear bearing, adjusting a depth position of a cut to be made on the wing-to-fuselage attachment, adjusting a width position of the cut, and moving the tool along a length direction of the cut to make the cut on the wing-to-fuselage attachment along the length direction at the adjusted depth position and the adjusted width position.

A multi-functional router base that includes associated components and various methods of use herein. The router base includes a base plate and an attachment assembly that is operably engaged with the base plate. The router base also includes a first attachment rod and a second attachment rod provided on the attachment assembly, where the first attachment rod and the second attachment rods are adapted to engage a router. The first attachment rod and the second attachment rod of the router base are linearly moveable relative to the base plate. As to the linear movement, the first attachment rod and the second attachment rod are transversely linearly moveable relative to one another and are vertically linearly moveable relative to the base plate based on the configuration of the router being operably engaged with the router base. An edge guiding fence may be operably engageable with the base plate.

The invention relates to a guiding device 100, a system comprising a guiding device and a tool 111 for surface treatment, a method for surface treatment with the guiding device 100 and a method for retrofitting a tool 111 with the guiding device 100. The guiding device 100 comprises at least one guide element 101, one angle device 102 and one connection arrangement 130 for connecting the guiding device to the tool 111. Furthermore, a predetermined angle between the plane 180 of the at least one guide element 101 and a plane of action 110 of the connectable tool 111 is set by means of the angle device 102. The guiding device 100 is furthermore characterised in that it is switchable between at least one flexible operating state and one rigid operating state.

A sled for guiding a common hand router to cut a precision planar surface on a workpiece has plywood frame rails spaced by cradles supporting the workpiece between the frame rails. Base rails riding on the upper edge surfaces of the plywood frame rails are sequentially incrementally advanced at intervals along the frame rails in an X-axis direction by a linear ratchet assembly. A router is reciprocated in Y-axis directions during the intervals between the sequential incremental advances of the base rails, cutting a precision planar surface on the workpiece. The router is adapted to adjust the Z-axis elevation of the router cutter. The sled may be manually operated or automated.

A drill guide for a drill bit of a chucked hand-held drill is disclosed. The drill guide includes a mount, a coupler, a telescoping guard, and a guide foot. The mount is configured to couple to a non-rotating portion of the chucked hand-held drill. The coupler extends from the mount and forms a chuck access window aligned with the chuck when the mount is coupled to the non-rotating portion of the chucked hand-held drill thereby allowing a chuck key to interface with the chuck. The telescoping guard extends from the coupler and is configured to telescope into a retracted position from an extended position. The guide foot is coupled to the telescoping guard such that the drill guide enshrouds the drill bit when the telescoping guard is in the extended position, and the drill bit passes through the guide foot when the telescoping guard is in the retracted position.

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.

In one example, an on-wing apparatus for in-situ cutting on a wing-to-fuselage attachment includes a first linear bearing disposed on a first mount plate to move in a first direction. A second linear bearing is disposed on a second mount plate to move in a second direction. The second mount plate is attached to the first linear bearing. A tool mounting member is attached to the second linear bearing. A cutter is attached to the tool mounting member to be adjustable, relative to the second linear bearing, in a rotational direction around an adjustment axis. One of the first direction and the second direction is a depth direction of the cut parallel to the adjustment axis, and the other is a length direction of the cut. A width position of the cut is determined by rotational adjustment of the cutter with respect to the second linear bearing in the rotational direction.
