    Abstract: According to prior art, especially wood workpieces are cut by means of band saws or gate saws, a chipping-type separation of the workpiece (5) being achieved by means of the toothing of the saw blades (2). Proceeding from the prior art, the invention relates to a novel device for separating materials (1) wherein an abrasive saw blade (2) of little blade thickness and having a close-toothed microtoothing (3) is used so that a grinding-type separation of materials is achieved. The resulting kerfs are considerably thinner and the cut edges are treated more gently than known from the prior art. The novel abrasive saw blade (2), however, requires more time-consuming blade guidance and blade cleaning and a different blade production. Treatment of wood and veneers.

  • Patent number: 7739937
    Abstract: A band saw blade guide includes a cylindrical chisel shaped member mounted at an oblique angle to a band saw blade. The blade guide adjusts the angle of the band saw blade by rotation of the guide about its axis. By rotating the guide about its axis, the angle of the chisel point guiding surface is changed thereby changing the angle of the blade. Further the blade may be guided by a single guide forced against one surface of the blade thereby eliminating the need for guides on both sides of the blade.

  • Publication number: 20100050847
    Abstract: A guide for a saw band or blade of a sawing machine is provided. The guide includes a bracket and high-strength sliders, which are mounted to a bracket for a lateral guide of the saw band or saw blade and which serve for gliding contact to a side face of the saw band or blade. The sliders are high-strength guide plates, provided with an edge upstream in reference to the direction of motion of the saw blade or saw band, which is at least partially arranged in a straight manner or with a constant curve, with the edge or its tangents extending tilted at an angle from approximately 0° to 90°, preferably from 20° to 70°, in reference to the direction of motion of the saw blade or the saw band. Furthermore, several guide plates are mounted to the bracket at a distance from each other, forming clear spaces.

  • Patent number: 7661194
    Abstract: The present invention is an attachable rolling plate assembly which can be attached as a single unit to a portable cutting tool to facilitate the safe rolling movement of the portable cutting tool on the workpiece. The invention comprises a front wheel housing portion, a back wheel housing portion, and two or three metal rods which interconnect the two housings. The housings removably retain a pair of spaced apart wheels and means to retain a cutting tool on the housings so that the cutting tool can be rolled on the workpiece during operation of the tool while the cutting blade portion of the tool extends between a pair of adjacent interconnecting rod members. The front and rear wheel housing assembly receives the cutting blade in between its pins or axles, so that the entire width of the saw plate is supported by the wheels during cutting.

  • Publication number: 20100005940
    Abstract: An articulating band saw apparatus provides a frame that includes a vertically extending section having upper and lower end portions. An elevator moves between the upper and lower end portions of the frame. A first hydraulic actuator is supported on the elevator for movement therewith. A first arm provides arm end portions, the first arm supported by the first hydraulic actuator. An end of the first arm supporting a second hydraulic actuator that is spaced away from the first hydraulic actuator. The second hydraulic actuator supports a second arm. An endless band type saw is mounted on the free end of the second arm generally opposite the second actuator. The band saw is movable by articulation of the first and second actuators and resulting movement of the first and second arms. In one embodiment, the band saw is a diamond wire saw.

  • Publication number: 20090320658
    Abstract: The present invention provides cutting methods and cutting apparatus that can precisely cut workpieces in complicated shapes with high aspect ratios regardless of materials of the workpieces. The present invention is cutting methods and cutting apparatus using a wire saw wherein cutting processing is performed for a workpiece by extending a cutting wire on a cutting arm that rotates around a wire's center axis or a real cutting position relative to a fixed section and rotating the cutting arm such that a cutting direction of the wire matches a support direction of a total stiffness that supports the wire.

  • Patent number: 7584688
    Abstract: Improved saw guide block and fluid for a multiple blade saw assembly. Individual guide blocks are disposed between adjacent saw blades, which blades are mounted on a common drive shaft and axially spaced. Each of the guide blocks has a pair of oppositely-directed block pads that create a magnetically-padded bearing surface. Each block pad includes magnetic portions and non magnetic portions. Each non magnetic portion has fluid delivery ports to allow the transport of ferromagnetic, lubricant, coolant, coating fluid to the magnetically-padded bearing surfaces. The magnetic portion forms a magnetic field of attraction in its vicinity for capture and adherence of ferromagnetic particles within the fluid, whereby a magnetic coating on the guide block bearings surfaces is continuously regenerated during operation of the saw assembly.
