摘要： The invention relates to a cutting insert having a polygonal upper side. Cutting edges, which are alternately configured as roughing cutting edges and finishing cutting edges, are provided at the edges of the upper side. The finishing cutting edges define an incircle (K1) having a diameter that is enlarged in comparison to a nominal size of the cutting insert, and the roughing cutting edges define an incircle (K2) having a diameter that is reduced in comparison to the nominal size of the cutting insert. The invention further relates to a cutting tool having a tool body on which at least one such cutting insert is disposed.

摘要： A cutting insert may include a base member including a plurality of tungsten carbide particles. In cases where a particle diameter distribution of the tungsten carbide particles is measured at intervals of 0.025 μm, the particle diameter distribution may include, as a maximum peak and a second peak, a first peak value that appears in a particle diameter range of 0.5-0.9 μm, and a second peak value that appears in a particle diameter range of 1.1-1.5 μm. A value of a particle diameter distribution frequency is larger than zero at a valley part where a value of the particle diameter distribution frequency reaches a minimum between the first peak value and the second peak value.

摘要： Tool for machining a workpiece, comprising: a holder having a first internal coolant duct; a cutting insert having a main cutting edge; a first fastening element for releasably fastening the cutting insert to the holder; a plate-like coolant guiding attachment having a second internal coolant duct; and a second fastening element for releasably fastening the coolant guiding attachment to the holder. In the assembled state of the tool, the first internal coolant duct is fluidically connected to the second internal coolant duct and the coolant guiding attachment covers at least a part of the cutting insert. The coolant guiding attachment comprises a first opening, which is configured as a recess or through-opening and allows access to the first fastening element, such that the cutting insert is separately releasable from the holder by releasing the first fastening element even when the coolant guiding attachment is fastened to the holder, and the coolant guiding attachment is separately releasable from the holder by releasing the second fastening element even when the cutting insert is fastened to the holder.

摘要： Chip discharge during high-feed machining and low-feed machining particularly in a high-depth-of-cut state or the like is improved so as to allow so-called freedom of feed during cutting to be improved. A cutting edge body of a cutting insert includes a front cutting edge formed on one end side in a longitudinal direction, the front cutting edge being a cutting edge formed on an intersecting edge between a peripheral side surface and an upper surface of the cutting edge body having a prismatic shape, a side cutting edge formed on one end side in a lateral direction, a recessed part provided in the upper surface of the cutting edge body to be subsequent to the side cutting edge in the lateral direction, and a wall part having a wavy wall surface formed in a portion of the recessed part and a discrete wall surface formed at a position between the wavy wall surface and the side cutting edge and including a plurality of surfaces which are discrete along the longitudinal direction.

摘要： To provide a cutting insert that is properly manufactured with ease of use. A cutting insert has a first end face, a second end face on the opposite side from the first end face, and a peripheral side surface that is parallel to a central axis connecting the center of the first end face and the center of the second end face and connects the first end face and the second end face. A first major cutting edge is formed on the outer edge of the first end face. A first flank facing the first major cutting edge is formed between the first major cutting edge and the peripheral side surface and has a negative clearance angle α with respect to the peripheral side surface. The peripheral side surface includes a first side surface facing the first flank. Between the first flank and the first side surface, a recess line is formed to extend along a virtual edge line where a virtual plane extending from the first flank and a virtual plane extending from the first side surface cross each other, and the recess line is formed with a notch on the virtual edge line.

摘要： A tool body to which a replaceable cutting insert is fixed includes: a holder: an insert mounting seat that is provided on a first surface of the holder; a clamp member that constrains the cutting insert placed on the insert mounting seat; and an operating member that presses a pressure receiving surface of the clamp member. The clamp member has the pressure receiving surface, a spherical head portion that is formed into a spherical crown shape, and a hook portion that protrudes to a side opposite to a side of the spherical head portion when seen from a side of the first surface. The insert mounting seat supports the clamp member to be swingable with the spherical head portion as a fulcrum, and the hook portion contacts a diameter reducing portion that is formed on an inner peripheral surface of an mounting hole for the cutting insert in a state in which the pressure receiving surface is pressed.
