Abstract:
An improved design of a cutting insert system includes a plurality of indexable peripheral milling cutting inserts adapted to be mounted on a peripheral milling tool holder. Each of the cutting inserts includes an insert width that is the same for each cutting insert. Each of the cutting inserts also includes a corner nose having a corner nose radius dimension that is different for each cutting insert, and an axial alignment clearance face that defines an equivalent face location and an equivalent clearance angle for each of the plurality of cutting inserts when the insert is detachably mounted on the tool holder.
Abstract:
A multi-function cutting tool is disclosed. The multi-function cutting tool includes a cutting insert (200) and a cutter body (300). The cutting insert has an upper surface (201), a lower surface (205), and first and second cutting edge corner parts (210) and (220), which are provided on the upper surface such that the upper surface has a symmetrical structure with respect to a diagonal direction. The cutting insert further has a major cutting edge part (230), a first minor cutting edge part (240), and a lowered cutting edge part (250). The major cutting edge part has a downwardly inclined angle ranging from 3° to 10°, and extends from the first cutting edge corner part towards the corresponding second cutting edge corner part. When seen in the front view of the cutting insert, the major cutting edge is defined by a convex curved line, which has a curvature radius of 1000 mm or more.
Abstract:
A face-milling insert, including a chip-removing main cutting edge adjacent to a first clearance surface, and a surface-wiping secondary edge adjacent to a second clearance surface, the main cutting edge forming an angle of 45° with an imaginary straight line in the extension of the secondary edge. Adjacent to a third clearance surface, an intermediate cutting edge is formed between the main cutting edge and the secondary edge, the intermediate cutting edge being shorter than the main cutting edge and forming an angle within a range of 20-40° with the extension line. The intermediate cutting edge transforms into the adjacent edges via arched part edges adjacent to convex clearance surfaces.
Abstract:
A double-sided reversible and indexable cutting insert has identical opposing first and second end faces and a peripheral side surface extending therebetween. A clamping through-bore extends between, and opens out to, the first and second end faces. The cutting insert has a median plane between the first and second end faces, and a through-bore axis extending perpendicularly through the median plane. The cutting insert also has a Y-fold rotational symmetry about the through-bore axis. The peripheral side surface has Y major side surfaces and Y minor side surfaces, each minor side surface interconnecting two adjacent major side surfaces. Each minor side surface is a section of a single cylindrical surface having a given radius, the given radius being greater than a minor side surface distance of each minor side surface from the through-bore axis.

Abstract:
1. The throwaway tip characterized that the shape is approximately square type plate late, and the corner angle of the another two corner tooth which adjoins each other of one face is made as 90° or less, and the other two corner edge which counters respectively is made as non parallel cutting tooth. 2. The throwaway type cutting tool characterized that two or more throwaway tip is the same as the throwaway tip of claim 1, and the throwaway tips are arranged so that the other two corner tooth projects respectively to a perimeter side of a tip of a main part of a tool, in a throwaway type cutting tool that the two or more throwaway tips are arranged so that the tip is projected respectively to a tip side of a main part of a tool.
Abstract:
The present invention provides a cutting insert, a rotating cutting tool holding said cutting insert and a cutting method using the tool which is able to prevent the occurrence of burrs and to cut a smooth finished surface.In a rotating cutting tool which carries a plurality of cutting inserts, at least one insert is made of single crystal diamond 3A, and the minor cutting edge of the insert has an arc shaped portion whose radius is in the range of 10 mm or more to 500 mm or less.A high hard material other than single crystal diamond, for example PCD 3B, is used for the remainder of the cutting inserts.It is preferable that a cutting edge of single crystal diamond 3A be projected to the rotating axis direction in the range of 0.01 mm or more to 0.05 mm or less, compared with the cutting edges of high hard material.
Abstract:
A side milling cutter with cutting inserts, by which side milling cutter a crank pin can be cut with a single feed motion. The plate-shaped cutting inserts are arranged on the periphery of the side milling cutter alternating between the left and right side in a peripheral direction, and are oriented essentially radially with their cover surfaces in relation to the cutter axis, which cover surfaces contain the tool faces. The cutting inserts are also arranged so as to form a gap on the periphery of the cutter which is so narrow that the length of the arc of action between the point of entry and the point of exit of cutting is greater than the half of the gap of the arrangement of cutting inserts on the periphery of the cutter. The present invention also relates to the configuration of the cutting inserts as indexable inserts which can be used on the left and on the right.
Abstract:
A cutting insert for milling has a generally perpendicular cutting face that is peripherally bounded by respective main cutting edges and has free faces set at a positive angle and having common edges forming auxiliary cutting edges. The insert has a positive cutting angle and the cutting face has in the region of an adjacent main cutting edge forming a cutting corner a flat or recess which extends into both adjacent main cutting edges.
