A saw blade for cutting stalk crops, such as for example maize or millet, has a planar flank and a facet flank and a sawing edge with a succession of saw teeth. The saw teeth are provided with a wear protection zone, the wear resistance of which is greater than that of a material of the base body of the saw blade. The wear protection zone is respectively located on the planar flank of each saw tooth. The saw teeth in the region of the tooth face have a cutting facet, starting from the facet flank. The cutting facet is configured at a distance from the planar flank of the saw tooth to form a blunt tooth cutting edge and, in a preferred embodiment, the cutting facet and the facet flank are configured without a wear protection zone.

A laterally cutting saw blade assembly includes a plate that has a pair of opposed faces, a center and a peripheral edge having a plurality of shoulders attached thereto. Each of the shoulders has a pair of opposed faces. The shoulders each have a distal edge with respect to the peripheral edge. The distal edge of each of the shoulders extends between a tailing edge and a leading edge of each of the shoulders. A plurality of teeth is provided. Each of the leading edges has one of the teeth attached thereto. The teeth extend laterally away from each of the opposed faces. The teeth form a plurality of cutting surfaces extending continuously from the distal edge toward the center a distance equal to at least equal to 1.90 cm. The plate is mounted to a cutting assembly and rotated to cut lateral to the opposed faces.

A stationary housing (3) has an interior space (5) and at least one interior wall (7). At least one sawblade (9) is rotatable with respect to the stationary housing (3), and has a periphery (12) provided with a plurality of cutting teeth (15) and a plurality of collecting notches (17). An inlet opening (19) for feeding material to the interior space (5), and an outlet opening (21) for dispatching pulverized material from the interior space (5) are provided in the interior wall (7) of the housing (3), with a plurality of recesses (23) facing the periphery (12) of the sawblade (9) receiving the cut material from collecting notches (17) of the sawblade (9), and reverting the cut material to the periphery (12) of the sawblade (9) so that the material is cut multiple times before dispatch. The interior wall (7) surrounds a main part of the periphery (12) of the sawblade (9), and the inlet opening (19) and the outlet opening (21) are in direct communication with the interior space (5) so that the material enters and leaves the interior space (5) during one revolution of the sawblade (9).

A cutting or grinding tool includes a blade. The blade includes a disc-shaped base metal, cutting or grinding tips (edges) provided on a peak (outer circumferential edge) of the base metal, and a protruding coating on a side face of the base metal along the entire outer circumference of the base metal.

A machining tool (1) includes a tooth (3) having a tooth tip (4) being covered with cutting particles (5) to form a plurality of geometrically undefined cutting portions. The tooth tip (4) is designed to be asymmetrical. The machining tool (1) thus is a 2-in-1 machining tool including differently designed sides of the tooth tips (4) which are suitable for efficiently machining different materials.

A method and device for controlling the feed rate of a saw blade which is provided with teeth and rotates about a center point relative to a workpiece during a machining process. During a rotation of the saw blade about the center point, the feed rate is selected differently during a machining process effected by teeth of different sectors of the saw blade, wherein the feed rate is selected to be lower during a machining process effected by teeth of sectors having larger radial spacing of the teeth from the center point than during a machining process effected by teeth of sectors having smaller radial spacing of the teeth from the center point. In this way, the operation of the saw blade can be optimized and the service life can be increased.

An accessory for oscillating power tools includes an attachment portion and a working portion extending along an axis and including a rear end portion, a front end portion with a cutting edge, a first lateral non-cutting edge, and a second lateral non-cutting edge. The cutting edge includes a first subset of teeth including at least one first tooth extending from the first lateral edge toward the axis, a second subset of teeth including at least one second tooth extending from the second lateral edge toward the tool axis, and a third subset of teeth including at least one third tooth disposed between the first subset of teeth and the second subset of teeth and intersecting the axis. Each first tooth and each second tooth has a first configuration and each third tooth has a second configuration that is different from the first configuration.

The invention relates to a cutting blade, in particular to a scythe-like blade or to a spiral blade, for an apparatus for slicing food products, in particular for a high-speed slicer, the cutting blade rotating about an axis of rotation during a cutting operation, having a radially outer peripheral edge which acts as a blade edge and which has a curved extent about the axis of rotation; and having a plurality of cutting teeth which are arranged distributed following one another along the peripheral edge, wherein each cutting tooth has a blade edge which comprises a cutting surface and a cutting edge radially outwardly bounding the cutting surface; wherein each cutting surface extends inclined with respect to a spanned plane perpendicular to the axis of rotation and/or with respect to a cutting plane; and wherein the inclination of the cutting surfaces varies along the peripheral edge.

A saw blade is provided having a noise and stress-reduction structure, the saw blade having a structure in which a plurality of diamond segments are mounted at a first unit and the first unit has a second unit, thereby reducing the noise generated during a cutting operation, while increasing heating performance with a relatively simple configuration, and simultaneously dispersing impact stress so as to prevent the occurrence of cracks.

Provided is a tip saw which is provided with saw blades formed at a predetermined interval on an outer periphery of a disk-shaped base metal and a tip securely attached to a base formed on each saw blade, in which flank faces and rake faces of the tips are set in a staggered manner, and the rake faces are provided at a negative angle of inclination in a direction opposite to a rotation direction of said tip saw, and when a workpiece material is thin-walled, the tips are in substantially fan shapes, and adjacent saw blades have a pitch of less than 3.5 mm or less than 3.0 mm therebetween.
