摘要： PROBLEM TO BE SOLVED: To form a band saw blade capable of sufficiently penetrating a workpiece in a state of reducing cutting force, having durability, and usefully manufactured by reducing a required polishing quantity. SOLUTION: The band saw blade 1a has a band and a tooth 1-9 extending from this band, and its tooth 1-9 is arranged in circulating main groups, and the respective main groups have at least two circulating set sub-groups. Set amplitude of the whole is the same as respective ones of the set sub-groups. Individual set amplitude on at least one specific tooth 1-9 existing in a specific position in a specific set sub-group, is different from individual set amplitude on a corresponding tooth 1-9 existing in a corresponding position in at least one of residual set sub-groups of the main groups. This invention relates to a manufacturing method of the band saw blade 1a. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a band saw body provided with an appropriate tooth shape against soft and tough metallic material by providing cemented carbide on the edge, specifying the rake angle and the clearance angle, and respectively severally providing right side setting teeth, left side setting teeth, and straight teeth. SOLUTION: The tooth 10 of a band saw is provided with cemented carbide on the edge 13, and the rake angle 11 is formed into 12-18 degrees, and the clearance angle 12 is formed into 5-8 degrees. These teeth are set, and this band saw is constituted of several right side setting teeth, several left side setting teeth, and several straight teeth. In this case, all the teeth 10 are desirble not to be chamfered to be straight cutting edge.

摘要： PROBLEM TO BE SOLVED: To provide a protection device for the teeth of a hand saw. SOLUTION: A protection device for the teeth of a hand saw includes an asymmetrical U-form division and a teeth protecting part having the same curvature as the sharpened teeth on the saw body. The base 16 includes a hang-down part 14 and a clasp 19 having a head 22 capable of penetrating a hole 14 in the saw body in a proper positioning predetermined relative to the saw and the protection device with the first end extending to mate with the front extremity of the saw. Another part to protect the teeth around the other end is equipped with an envelope 21 to properly prevent a movement between the saw body and protection device when the sharpened teeth on the saw body are inserted into the part of U-form division.

摘要： PROBLEM TO BE SOLVED: To prevent vibration, instability and a wavy cut surface from being generated by a method wherein each set of saw teeth has at least a lateral rake angle of a negative type of a specific angle, and a side face clearance angle larger than the lateral rake angle. SOLUTION: At least an upper part of a front rake face 20 is worked by grinding in an acute angle concerning an intersecting line extending at a right angle to a central line. This angle corresponds to a required difference between a side face clearance 16 and a lateral direction rake angle 18. This angle is preferably at least 5 deg.. The lateral rake angle 18 is at least a 5 deg. negative type angle, and the side face clearance angle 16 is larger than the lateral angle and preferably larger at least by 5 deg.. The side face clearance angle, in order to keep a low cutting force and to avoid work hardening of a cutting surface, can be made sufficiently large. Besides, the lateral rake angle, in order to minimize a lateral force in grinding work, can be sufficiently decreased.

摘要： PROBLEM TO BE SOLVED: To provide a band saw blade with increased number of cutting teeth per unit length while maintaining the capacity for cutting a difficult material. SOLUTION: A band saw blade of the present invention includes a band plate and teeth (11a to c, 12a to c, 13a to c, 14a to c, 15a to c, 16a to c, 17a to c, 18a to c) projecting from the plate. The teeth are arranged in a repetitive main group, and each main group has repetitive pattern subgroup and repetitive set subgroup. Each pattern subgroup has teeth (11a to 18a, 11b to 18b, 11c to 18c) of at least two different heights, high and low, and even number of teeth. The set subgroup has at least five kinds of teeth of normal left set, middle left set, no set, middle right set, and normal right set (11a to 16a, 17a to 14b, 15b to 12c, and 13c to 18c) and six teeth.

摘要： PROBLEM TO BE SOLVED: To provide a saw blade which enables straight and smooth cutting by repeatedly providing a group of a pair of saw-setting teeth saw-set on the right and left of a saw blade, a wide blade having straight and basically parallel horizontal blades 12, and a high tooth having a shoft top balde between two chamfering blades. SOLUTION: In this saw blade having four kinds of tooth forms, a saw-set tooth 14 for cutting a side surface 13 of a section is formed in front of a saw-set tooth 15 saw-set on the opposite side, and to form the surface of a smooth section, a wide blade 16 having straight and basically parallel horizontal blade 12 is formed in the rear of the saw-set tooth 15. By the blade 16, the lateral direction of the saw blade is stably held, and the surface 13 cut by saw-set teeth 14, 15 is cut smooth. Further, in the rear of the blade 16, a high and straight tooth 17 having a short top blade 18 between two chamfering blades 19 is formed. One group of the such blades is repeatedly provided in the longitudinal direction to form a saw blade excellent in cutting performance.

摘要： PROBLEM TO BE SOLVED: To provide a tooth profile of cutting tools that can offer such a path of chips as reduces the abrasion of edges near tool corners. SOLUTION: This metal cutting tool in form of, for example, a saw blade and a grooving tool, has teeth each having a major cutting edge 14 and side cutting edges. Each major cutting edge 14 is rounded on a large radius via a polishing process, and each side cutting edge has a radius made smaller by flat-grinding of at least a part 23 of its related side face after the rounding by the polishing process.
