A tool of the present disclosure includes a tip end portion. The tip end portion has a surface. At least a part of the surface includes a plurality of protrusions, a first recess provided by contact between ends of two adjacent protrusions of the protrusions, and a second recess different from the first recess. The second recess is provided inside at least one of the protrusions or provided to extend across the two adjacent protrusions.

A ring forming step includes welding opposite ends of a band saw blade including a body part having a band shape, and a tooth part including a plurality of teeth formed on one side part of the body part, to form a ring shape. A polishing step includes polishing an inner surface, an outer surface, and an end face on a side opposite to the tooth part in the ring-shaped band saw blade subjected to the ring formation. A tip tooth tip forming step includes positioning, after the polishing step, the ring-shaped band saw blade subjected to the ring formation by use of one of the inner surface and the outer surface, and the end face as references, joining a cutting tip to tooth tips of the plurality of teeth by welding, and polishing the joined cutting tip to form a tooth tip shape.

A wear-resistant armored cutting tool may be provided. The wear-resistant armored cutting tool may include a tool body, a bolster, at least one wear-resistant member, and a cutting tip. The bolster may be fixedly attached to the tool body with an end of a surface of the tool body disposed adjacent the bolster. The at least one wear-resistant member may be fixedly attached to the tool body. The at least one wear-resistant member may be disposed adjacent to the end of the surface of the tool body. The cutting tip may be fixedly attached to the bolster. The bolster, the at least one wear-resistant member, and the cutting tip may each have a material hardness which is greater than that of the tool body.

The invention relates to a device (2) for welding hard material elements (4) onto teeth (6) of a saw blade (8), comprising a saw blade feed device (12) for moving the saw blade (8) in a feed direction (14), such that a tooth (6a) of the saw blade (8) can be brought into a target position (16) in a working region (10) of the device (2), comprising a first centering device (30) for centering the saw blade (8) transversely to the feed direction (14), comprising a second centering device (32) for centering a respective hard material element (4) transversely to the feed direction (14), comprising a resistance welding device (24) having a welding electrode (26) that can be deployed into and withdrawn from the working region (10), comprising a supply device (28) for supplying and transferring a respective hard material element (4) to the welding electrode (26), and it being possible for the welding electrode (26) to be deployed in such a way that the hard material element (4) can be brought toward the tooth (6a) to abut the tooth (6a). According to the invention, the hard material element (4) can be centered relative to the centered and fixed saw blade (8) by means of the second centering device (32), and the first and second centering device (30) are provided in a common assembly (38), such that the centering of the saw blade (8) by the first centering device (32) predetermines a centering position for the subsequent centering of the hard material element (4) by the second centering device (32).

A mount system and method of manufacture for e.g. a machine vision camera is disclosed. The mount system comprises a rectangular base, a lower clamp disc, an upper clamp disc, a tilting plate, an expansion clamp, and an O-ring. The expansion clamp comprises a tapered head screw and an expandable mandrel, both typically made of stainless steel. The mount system facilitates improved machine vision by enabling effective mounting of machine vision cameras in smaller spaces and/or spaces requiring unusual angles and intricate positioning. The mount system is also advantageous in inhospitable environments having harsh environmental factors. The mount system is also easier for machine vision personnel to learn and understand.
