  • Patent number: 9138816
    Abstract: A double-acting pipe cutting band saw apparatus and method for using the same are capable of cutting a relatively large workpiece with a relatively small size band saw blade, furthermore, it improves the cutting efficiency and life of the band saw blade. Since the pipe to be cut is put on a rotary table which is mounted a slide table, it can be continuously rotated and moved with respect to the band saw assembly during the cutting operation. Hence, the pipe to be cut can be completely cut by a band saw blade whose operable cutting length of the band saw blade does not have to be larger than the diameter of the pipe, which reduces cutting time while improving cutting efficiency. The service life of the band saw blade is extended since the cutting operation is not just performed by the rotation of the band saw blade.

  • Patent number: 8943940
    Abstract: An apparatus for balancing a wheel includes a tool and an arm control module. The tool is mechanically coupled to an arm and includes a leading edge, a trailing edge, and a face surface that forms an arc between the leading and trailing edges. The arm control module actuates the arm to position the leading edge of the tool a predetermined distance from an edge of a deck of a cutting apparatus to receive a piece of non-segmented wheel weight material. A blade of a cutting apparatus passes between the edge of the deck and the leading edge of the tool to cut the piece from the non-segmented wheel weight material.

  • Patent number: 6772749
    Abstract: A band saw with a complex coordination of a tilting motion and a translational motion between the workpiece and the band saw blade, so that a curved cut is made in the workpiece. The geometric parameters of the cut can be continuously adjusted. This makes it possible to optimize a contact length of the saw blade in the workpiece, which is an important factor in the cutting process. It is thus possible to saw workpieces made of stone and similar materials that are typically difficult to cut. The cut and the contact length of the saw blade can be tailored individually to each workpiece to be sawed. Thus, workpieces of different geometrical dimensions and different material properties, in particular with different material hardnesses, can be processed using the band saw according to the invention without having to undertake significant changes.
