Abstract: A rotary cutting tool is provided for cutting an opening in a sheet of material (e.g., drywall) around a pre-installed item (e.g., an electrical box). The cutting tool may include a shaft, at least one cutter, a guide tip and a shoulder formed by a lower edge of the cutter adjacent the guide tip. The shoulder may have a width that corresponds to the width of a wall of the pre-installed item. The width of the shoulder may be equal to the width of the wall, or it may be slightly greater than the width of the wall. The guide tip may include a bearing to prevent marring of the wall of the item when the guide tip is rotating and in contact with the wall. An adjustable collar and corresponding bearing may also be disposed around the shaft for controlling a preferred cutting depth of the cutter. The cutting tool may be engaged with any suitable rotary tool, including one having an adjustable table for controlling a preferred cutting depth of the cutter.

Abstract: A surface of a workpiece is traced when a machining tool is pressed onto the surface of the workpiece under force control so as to find the positional data of the surface shape. This positional data is corrected by an error caused by a bend of a robot. The positional data is compared with the target shape of the surface, from which the burr is removed. A shift of the surface shape in the normal line direction is found. The burr generation start position, the burr generation end position and the height of the burr are found by the shift start position, the shift end position and the shift size. A machining program is made which is composed of a pass connecting the burr end position with the burr start position and also composed of a cutting pass for removing the burr, and the thus made machining program is executed. As the burr position is found and the burr is removed when the machining tool is moved to the burr position, the burr can be effectively removed.

Abstract: A cutting tool and mounting system includes a tool carrier arranged to be mounted onto a workpiece, a cutting tool assembly carried by the tool carrier, and a tracking assembly connected to the cutting tool assembly and positioned to follow the contour of an outer surface of the workpiece. The cutting tool assembly includes a cutting tool arranged to be rotated about a longitudinal axis and a tool driving system connected to and arranged to transmit rotary input motion to the cutting tool. The cutting tool is secured by the tool driving system to be fed along its axis of rotation and transversely of its axis of rotation for cutting a workpiece through a wall thickness of the workpiece to impart a beveled surface to a severed end portion of the workpiece.

Abstract: A versatile adjustable stylus for key duplicating machine comprising an arm laterally secured at one end on the periphery of a cylindrical body, and laterally movably arranged at the other end on an engagement base secured on a substrate of the key duplicating machine in accordance with the different duplicating distances between the duplicating cutter and the original keys to be duplicated; a retractable spring-loaded tracer movably engaged in one end of the cylindrical body, for pre-tracing the depths of the key teeth of an original key; and a regulating grip angularly movably engaged in the other end of the cylindrical body, for regulating the retractable movement amount of the retractable spring-loaded tracer.

Abstract: An improved spring tracer for duplicating machine for punched and laser keys comprising a longitudinal spindle suspended from an end of a synchronous lateral lever having the other end laterally connected to a longitudinal shaft for a duplicating tool in parallel with the longitudinal spindle, which can be longitudinally slidably secured on a body portion in accordance with a common longitudinal axis of the longitudinal spindle; a spring-loaded tracer engaged in the inner lower end of the longitudinal spindle for biasing a tracer stylus against an original punched or laser key by means of the spring force for tracing the depths of the key teeth of the original punched key in accordance with the said common longitudinal axis; and a regulating sleeve rotatably secured at the outer lower end of the longitudinal spindle for regulating the elevation of the spring-loaded tracer in accordance with the said common longitudinal axis, in order that a regulating action, a securing action and a biasing action can be effe

Abstract: The invention relates to an electric power tool with a housing, in which a drive mechanism is received; the electric power tool includes a shaft, with a chuck (20) received in it, for receiving a tool insert (19). The chuck (20) is surrounded by an annular bearing face (9). The bearing face (8, 9) includes receiving elements that enable the guidance of the electric power tool on a guide rail (1, 35), such as receptacles (21, 22; 31, 32) and (33) for slip-on tools (25), such as templates, that can be received on the support (8, 9).

Abstract: The miller comprises a pair of benches situated on both sides of a framework, in such a manner that on the upper crossbar is mounted, displaceable and guidable, a transverse support that carries a couple of vertical arms on which are mounted the corresponding tools, the arms being dispaceable towards one side or the other with respect to the support, while the tool that is borne by each of the arms may move upward/downward, as well as rotate, in such a manner that a combination of these movements produced by their corresponding motors allows simultaniously making two pieces that are symmetrical or the same, as well as effect simultanious digitalized work with one arm and milling with the other, after having mounted the corresponding tool on one arm and a digitalizer on the other.

Abstract: A cutting tool for trimming a laminate flush with the surface of a substantially perpendicular laminate. The cutting tool includes a ball bearing guide assembly and a glue well shaft section. This glue well shaft section prevents softened glue encountered during trimming operations from contacting the ball bearing guide assembly. A washer provided between the glue well shaft section and the ball bearing guide assembly further prevents softened glue encountered during trimming operations from contacting the ball bearing guide assembly.

Abstract: A tracing head is disclosed which will allow a programmable router to trace he programmed path of the router on an inexpensive media to check the programming. This avoids the time and material wastage resulting from cutting metal plated circuit boards without being able to check the programming path.

Abstract: A carbide tipped cutting tool adapted to shape the edge surface of a counter top which opens about a sink or bowl mounted therebeneath. The cutting tool is provided with a plastic follower adapted to engage the side wall of the sink or bowl to facilitate cutting and shaping of the edge portion of the counter top. The plastic follower is formed of nylon or Delrin and captively holds a ball bearing member therein.

Abstract: A carbide tipped cutting tool adapted to shape the edge surface of a counter top which opens about a sink or bowl mounted therebeneath. The cutting tool is provided with a nylon follower adapted to engage the side wall of the sink or bowl to facilitate cutting and shaping of the edge portion of the counter top. The nylon follower is mounted on a bearing member with a second bearing member mounted beneath the nylon follower to prevent inadvertent dislodging from the shaft of the cutting tool.

Abstract: An X-Y coordinate carriage for a routing machine with which such a routing machine can be retrofitted. The coordinate carriage includes a cross-carriage and a longitudinal carriage having a torsion- and bending-resistant frame of lightweight construction, displaceably guided by mutually spaced bearings on a guide shaft mountable laterally to a worktable of the routing machine and supported on an opposite side of the worktable by a support roller against a support rod fastened laterally thereto and running parallel to the guide shaft. Guide shafts and retaining blocks support and guide the cross carriage, and bearing blocks are provided for displaceable mounting the cross carriage. The bearing blocks are disposed in spaces between hollow members of the longitudinal carriage and the cross carriage, whereby the guide shafts run approximately at a level of longitudinal horizontal center plane of the hollow members of the longitudinal carriage.
