Roll Or Collar Coaxial With Cutter Patents (Class 144/253.3)
  • Patent number: 7452169
    Abstract: A rotary cutting tool and method for cutting a shape in a workpiece. The rotary cutting tool includes a shank portion, a cutting portion, a bearing connected to one end of the cutting portion, and a rub collar attached to the periphery of the bearing. The outer diameter of the rub collar is selected to be larger than the diameter of the cutting portion. The rotary cutting tool is used to cut a workpiece, such as decorative plastic laminate, to the approximate shape of the substrate, such as a counter top, to which it will be mounted. The larger diameter rub collar allows the workpiece to be cut larger than the dimensions of the substrate in order to reduce the level of skill and amount of labor required for the cutting operation and subsequent placement of the workpiece onto the substrate.

  • Patent number: 7226257
    Abstract: A router bit with a position stop is disclosed. The router bit includes a body with a collar extending outwardly from it and a shaft extending outwardly from the collar. At least one cutter blade is mounted to the body and the cutter blade may be used to cut a profile into a workpiece. The collar has a first diameter, the shaft has a second diameter and the first diameter is larger than the second diameter. The collar has a face formed a spaced distance or height from the transition point between the collar and the body. The face rests against the upper surface of a chuck when the shaft is secured in the chuck. This allows the body and hence the cutter blades to be held a predetermined distance above the upper surface of the chuck. A second router bit may be provided to cut a complimentary second profile in a second workpiece.

  • Patent number: 6626617
    Abstract: In order to further develop a process for making a groove in a board-like workpiece by means of a processing machine, wherein the workpiece is placed on a supporting table of the processing machine aligned essentially horizontal for holding the workpiece in a machining plane and wherein a milling unit held on a machining head of the processing machine is displaced and a groove is thereby milled into a workpiece by means of a milling disk rotating about a drive shaft aligned parallel to the machining plane, in such a manner that the groove can be milled more precisely with a defined groove depth it is suggested in accordance with the invention that the milling unit be guided at right angles to the machining plane by means of a touch roller associated with the milling disk and adapted to roll on the workpiece. In addition, a processing machine for carrying out the process is suggested as well as the use of the processing machine for the milling of a groove into a multilayered or composite material board.

  • Patent number: 6568441
    Abstract: A pair of holding arms which can be installed quickly and used to press a workpiece in a safe manner against a guide fence, regardless of the cuts made upon it, when the workpiece is moved past a shaper having cutter blades rotatably mounted on a stationary shaft. Each holding arm includes a rubber-faced roller, an elongated, solid rod of angular transverse cross-section, and a track-mounted post for supporting the rod in a horizontal position. Contact between the workpiece and the holding arm is made through the roller which is vertically mounted on one end of the rod. The post includes a clutch plate for locking the horizontal extension of the rod. Each roller can be quickly moved forward into contact with the workpiece without releasing the clutch plate. To move the roller backward—away from the workpiece, the user releases the clutch plate with one hand and pulls backward on the rod with the other.
