  • Patent number: 8091459
    Abstract: A method for manufacturing a rotary tool for chip removing machining with at least one chip flute that extends in the longitudinal direction of the tool. The method involves preparing a mixture of a cemented carbide, cermet or ceramics powder and a carrier, such as a polymer, and placing the mixture in an extruding machine. The mixture is extruded in a feed direction by means of a die to form the diameter of the mixture body. The mixture body passes against a chisel which forms a chip flute in the outer periphery of the mixture body by chip-removing machining. When the chisel is displaced away from the mixture body, a non-fluted shaft portion is formed. By rotating the mixture body while contacted by the chisel, a helical chip flute can be formed. Alternatively, the body could be twisted after a straight flute has been formed, whereupon the flute becomes helical.

  • Patent number: 8011281
    Abstract: A punching device includes a detecting unit, a punching unit, a moving unit, a storage unit, and a controlling unit. The detecting unit detects a lateral edge position of a recording medium to obtain edge position data. When the edge position data does not indicate an error value, the edge position data is stored in the storage unit as reference data. The controlling unit determines, when the edge position data indicates an error value, a movement amount of the punching unit based on reference data previously obtained and stored in the storage unit. The moving unit moves the punching unit by the movement amount in a direction perpendicular to the conveying direction of the recording medium.
