摘要： In a cutting tool having an indexable cutting insert with exactly four cutting portions, the cutting insert is removably securable to an insert holder by a fastener. The cutting insert has two opposing end surfaces with a peripheral side surface extending therebetween, and each cutting portion has a major cutting edge formed by the intersection of a rake surface and a relief surface. The peripheral side surface has first and second pairs of opposing side surfaces which include the four relief surfaces and the four rake surfaces, respectively. In an end view, four cutting points on the four major cutting edges define the transitions between the first and second pairs of opposing side surfaces, and a minimum first length dimension between the second pair of opposing side surfaces is less than six-tenths of a minimum second length dimension between two of the four cutting points.

摘要： A three-way indexable throwaway tip for deep-hole drilling can be used as a center cutting blade body for a drill head in either whole cutting type or uncut core break-off type applications. The throwaway tip for deep-hole drilling is of a thick plate body having a three-fold symmetry with three cutting sections that are rotationally spaced apart at a central angle of 120 degrees. When mounted on a drill head, one cutting section of the throwaway tip faces a drilling direction. The forward facing blade edge of that cutting section includes an inner blade edge shorter in blade length and an outer blade edge longer in blade length forming an apex. The outer blade edge is composed of two consecutive blade edge portions of a peak-side outer blade edge portion having a smaller outer blade edge angle and a corner-side outer blade edge portion having a larger outer blade edge angle.

摘要： A disposable cutting insert for a boring cutter can reduce the roughness of a cut surface and achieve a mirror-like surface effect. The disposable cutting insert has a long curved blade edge, and the radius vertex of the long blade edge is deviated slightly from an external side of a vertex of the radius of cutting edge. A short curved blade edge is formed between the radius arc vertex and the radius arc vertex of the cutting edge. The vertical distance of the short curved blade edge is greater than the feed rate. The cutting edge cuts the work piece and the short curved blade edge can scrape a small size of material precisely for scraping the peak cut by the cutting edge and lower the height of the peak, so as to lower the surface roughness, and produce a mirror-like surface for an internal periphery of a bored hole.

摘要： A tangential indexable cutting insert can be used for metal cutting processes in general and for radial and axial turning of a stepped square shoulder in particular. The cutting insert exhibits 180° rotational symmetry about three mutually perpendicular axes. The cutting insert has generally “S”-shaped cutting edges extending between raised and lowered corners. The cutting edges and side surfaces are concave in an end view of the cutting insert. The cutting insert enables radial and axial turning operations of a square shoulder with unlimited depth of cut.
