  • Patent number: 11235402
    Abstract: Saw blades and methods of machining saw blade tooth profiles of saw blades. The saw blades include a blade body and a plurality of teeth defined by the blade body. Each tooth includes a tooth back, a tooth tip, a tooth face, and a tooth gullet. In at least one tooth, a relief region extends toward the tooth back and separates the tooth face from the tooth gullet. The methods include supporting the saw blade with a blade support structure and advancing the saw blade with a blade advance structure. The methods also include dry-machining a finished tooth profile in a working portion of the saw blade in a single pass. The dry-machining includes dry-machining with an end mill by operatively translating the end mill relative to the saw blade and within a plane that is at least substantially perpendicular to an end mill rotational axis of the end mill.

  • Patent number: 9610640
    Abstract: A method and apparatus for removing a section from a tire is disclosed. The method and apparatus are configured so that one side of a saw blade used to cut a section from a tire is treated by dulling. The treatment allows for the removal of a section of a tire so cords embedded in various layers of the tire are protected from damage and the surface texture surrounding the removed section of the tire is adequate for repair.

  • Patent number: 9216481
    Abstract: A method of creating an arbor mounting hole in a blade. The arbor mounting hole is created by making a first model of an arbor mounting hole that fits onto the asymmetrical mounting arbor. The first model has a first long flat edge and a first center of rotation. A mirror image of the first model is used to create a second model. The second model has a second long flat edge and a second center of rotation. The first model and the second model are superimposed so that the first center of rotation aligns with the second center of rotation and the first long flat edge aligns with the second long flat edge. The superimposition creates a compound model. A symmetric arbor model is formed about the compound model. The symmetric arbor model is cut into the blade.

  • Publication number: 20130180375
    Abstract: A reciprocating saw blade includes a body, and the body includes a connecting portion for connecting the blade to the saw, and a cutting edge. The cutting edge includes a plurality of teeth organized in an overall tooth set pattern. The overall tooth set pattern approximately corresponds to the stroke length of the reciprocating saw. By the overall tooth set pattern corresponding to the stroke length of the reciprocating saw, the cut time is decreased, the life of the blade is increased, the vibration is minimized and/or a smoother finishing cut is enabled.

  • Publication number: 20020184981
    Abstract: A method of preventing a tooth from continuously breaking in a band saw blade, comprises the steps of: moving the band saw blade to a longitudinal direction and moving the band saw blade to a cutting direction perpendicular to the moving direction of the band saw blade so as to cut a work; bringing a projecting portion disposed at a rear position of a surface of relief at the back of a tip in a saw tooth broken into contact with a bottom portion of a cutting groove in the work when the tooth breaking is generated in the saw tooth of the band saw blade; and limiting a cutting amount of the following saw tooth, thereby preventing the following saw tooth from breaking.
