A cutting tool with a plurality of cutting elements connected to a support structure wherein a portion of the support structure is configured to flex or bend based on the rotational frequency of the cutting tool. The rotational frequency of the cutting tool is a product of the design and composition of the tool.

Methods of grinding a sawblade include providing a sawblade plate; fabricating a plurality of sawblade teeth in the sawblade plate, each of the plurality of sawblade teeth having a pair of opposite tooth surfaces, a tooth back, a tooth gullet, a tooth face extending generally from the tooth back to the tooth gullet and a tooth edge on the tooth face; forming at least one blade relief in at least one of the opposite tooth surfaces of each of the plurality of sawblade teeth at the tooth face generally between the tooth edge and the tooth gullet; grinding the tooth edge of each of the plurality of sawblade teeth by rotation and movement of a grinding wheel along and against the tooth edge generally from the tooth back to the blade relief; and terminating the movement of the grinding wheel at the blade relief.

A novel approach to a commercial circular saw blade designed for efficient lumber cutting as well as extended saw blade life because of a reduction in friction and better heat dispersion. The saw plate has thicker body transitioning to a thinner rim at a point between the bottom of the gullet and the bottom of the tooth, generally occurring at the hook of the gullet. This design increases the lateral stiffness of the blade, improves accuracy, maximizes sawdust ejection, eliminates blade wandering, decreases the amount of the cut waste and allows for increased cutting speeds without decreasing the performance or longevity of the blade. This design goes against traditional, prior art saw blade design because of its interpretation of wood physics, blade friction and side clearance tolerances.

A circular saw blade includes a circular plate-like body having a first side face, an opposite second side face, a periphery, and a central opening defining a center point, and rotatable in a cutting direction. A plurality of circumferentially-spaced teeth are separated by a plurality of gullets. Each tooth has a rake face, a top face, a cutting edge at a junction between the rake face and the relief face, a first lateral face joined to the top face at a first top edge, and a second lateral face opposite the first lateral face and joined to the top face at a second top edge. The teeth include a plurality of first beveled teeth, each with its top face beveled radially inward from its first top edge to its second top edge, a plurality of second beveled teeth, each with its top face beveled radially inward from its second top edge to its first top edge, and a plurality of unbeveled teeth. The first beveled teeth, the second beveled teeth, and the unbeveled teeth are arranged in an alternating top bevel+raker pattern. The first top edge of the second beveled tooth is disposed radially inward toward the central opening from the first top edge of the first beveled tooth by a first drop distance.

A saw blade includes a main body having a first surface, a second surface on an opposite side of the main body from the first surface, a proximal edge portion, a distal edge portion, and first and second side portions extending between the proximal and distal edge portions. The proximal edge portion is configured to be coupled to a rotatable hub such that the saw blade is held in a curved shape with the first surface defining an outer radius when the saw blade is coupled to the rotatable hub. The distal edge portion includes a plurality of cutting teeth, and the second surface includes a cutting structure configured such that a radius of an arc swept by the cutting structure when the saw blade is rotated is substantially equal to the outer radius of the first surface.

A fluid-driven ring saw includes a ring saw blade that is supported and driven by a fluid. The fluid-driven ring saw can include one or more pairs of fluid nozzles. Each pair of fluid nozzles can include a first fluid nozzle separated from a second fluid nozzle by a gap. The ring blade can be positioned within the gap. The ring blade can include a plurality of holes. The one or more pairs of fluid nozzles can deliver fluid jets that impinge upon the plurality of holes of the ring blade to drive rotation of the ring blade. The ring blade can be driven without direct contact of a mechanical linkage, such as a belt or chain. The ring blade can be relatively thinner than ring blades driven by mechanical linkages.

Retention apparatus and systems for material removal machines are disclosed. In some examples, a material removal machine having a material removal tool (e.g., a saw blade, an abrasive saw, a polisher, a grinder, and/or more general material preparation and/or testing tool) is secured to a spindle using a spring loaded nut. The spring loaded nut of the present disclosure self-tightens when the material removal tool is rotated. Additionally, the spring loaded nut requires a smaller force to attach and/or remove the spring loaded nut, allowing for tool-less and/or low torque attachment and/or removal.

A tipped circular saw blade includes a disk-shaped metal base having a central axis of rotation, and a plurality of circumferentially-spaced tips extending radially outward from an outer periphery of the metal base. Each tip includes a flank along the radially outer portion thereof, a side face located along a side of the flank, and a chamfer extending between the flank and the side face. The chamfer is oriented at a chamfered angle with respect of the flank. Further, each tip includes a cutting edge located on an end of the flank in the circumferential direction. The cutting edge is configured to cut the workpiece. In addition, each tip includes a groove formed on the flank and extending circumferentially from the cutting edge. The width of the groove may be 0.20 mm to 0.30 mm.

A cutting disk for workpieces, particularly workpieces of fiber-reinforced composite materials, has a base body which is provided at least in some areas with a circumferential toothing and with a flank toothing arranged on at least some areas and on at least one lateral surface. At least with the majority of circumferential teeth, the main cutting edges do not directly encounter the main cutting edges of the adjacent flank teeth, and the main cutting edges accordingly do not define a common rake face.
