Abstract: During the manufacture of a bandsaw blade, a rotary hone forms, in a clearance side of each tooth, a narrow flat land. A leading edge of the land defines a sharp cutting edge. The land has a width no longer than ten percent of the pitch distance of the teeth.

Abstract: In a method and a system for determining the feeding speed when bandsaw cutting a workpiece, the tooth pitch TP of the bandsaw blade is determined in a first unit depending on the shape and dimensions of the workpiece. In a second unit feeding depth per tooth is determined depending on properties of the workpiece material and the width of the bandsaw blade. The bandsaw blade velocity BS is determined in a third unit from the width W of the workpiece and the hardness of the workpiece material, whereafter the cutting time T is determined in a first calculating unit from the height H of the workpiece, the feeding depth per tooth, the tooth pitch TP and the blade velocity BS. In a second calculating unit the feeding speed MH for the bandsaw blade is then determined by the equation MH=H/T. A computer program, when executed on a computer, performs this determination of the feeding speed when cutting a workpiece with a bandsaw from supplied input data.

Abstract: A bandsaw blade includes a blade beam carrying a plurality of cutting teeth separated by gullets. A clearance angle of the teeth is smaller than 35°, and the back of a leading tooth has a convex transition to a gullet. The radius of the gullet is larger than ½ of the depth of the gullet.

Abstract: A bandsaw blade for sawing of metal where each tooth has a narrow flat land (12) without clearance angle and a sharp cutting edge (14) in front, manufactured by moving the blade longitudinally with the tips of the teeth in contact with one or more slowly rotating hones (11) before possible setting and before joining to loops, thus providing less risk of tooth damage, less cutting force and greatly reduced noise. The invention also relates to a method for manufacturing a bandsaw blade with teeth.

Abstract: In a method and a system for determining the feeding sped when bandsaw cutting a workpiece, the tough pitch TP of the bandsaw blade is determined in a first unit (6) depending on the shape and dimensions of the workpiece. In a second unit (12) feeding depth per tooth is determined depending on properties of the workpiece material and the width of the bandsaw blade. The bandsaw blade velocity BS is determined in a third unit (22) from the width W of the workpiece and the hardness of the workpiece material, whereafter the cutting time T is determined in a first calculating unit (30) from the height H of the workpiece, the feeding depth per tooth, the tooth pitch TP and the blade velocity BS. In a second calculating unit (32) the feeding speed MH for the bandsaw blade is then determined by the equation MH=H/T. A computer program, when executed on a computer, performs this determination of the feeding speed when cutting a workpiece with a bandsaw from supplied input data.

Abstract: A metal cutting bandsaw blade includes a strip and a recurring group of teeth projecting therefrom. The recurring group of teeth has a setting pattern and a height pattern. The setting pattern has at least three units selected from the following setting types: (a) unset teeth (b) teeth set to the right (c) teeth set to the left. The setting pattern includes at least one of each of the setting types. The height pattern has at least two selected from the following height types: (a) high teeth (b) low teeth. The height pattern includes at least one of each of the height types. The total number of teeth in the recurring group is the product of the number of setting units and the number of heights units. The number of setting units is incommensurable with the number of height units. The number of teeth set to the right in the recurring group is equal to the number of teeth set to the left. All of the set teeth in the group have substantially equal setting widths.

Abstract: A cutting element, cutting edge and method of making cutting edges is disclosed. A compound material, preferably containing 30-70 vol % of carbides, nitrides and/or carbonitfides, is co-extruded with a steel cover. The co-extended product is cut into tip blanks whose outer surface corresponds to surfaces of a cutting element body. The steel cover is brazed to corresponding contact surfaces on bodies of a cutting element, e.g., a saw blade, and the cutting edges are ground by removing portions of the steel cover and the compound material.
