Method and strip steel knife from a steel strip having a bainite and decarburized surface. The steel strip has a generally rectangular cross-section, and the method includes machining a plurality of beveled surfaces in a region of a longitudinal edge of the steel strip to create at least a cutting surface defining a longitudinal cutting edge; first hardening at least a part of the cutting surface to form a first cutting edge region of the longitudinal cutting edge; smoothing the cutting surface of at least the first cutting edge region toward the longitudinal cutting edge; and at least one further hardening in the first cutting edge region to form a distal cutting edge region of the longitudinal cutting edge within the first cutting edge region having an increased material hardness with respect to the first cutting edge region located outside the distal cutting edge region.

An iron-based sintered alloy, which has a composition including, in terms of percent by mass, Ti: 18.4 to 24.6%, Mo: 2.8 to 6.6%, C: 4.7 to 7.0%, Cr: 7.5 to 10.0%, Ni: 4.5 to 6.5%, Co: 1.5 to 4.5%, Al: 0.6 to 1.0%, the balance being Fe and unavoidable impurities, wherein the alloy has a structure in which hard particles are dispersed in an island form in a matrix, among other characteristics.

A rotary cutter includes a die cut roll having a cutting blade, and an anvil roll positioned so that a roll surface faces the cutting blade. The roll surface of the anvil roll is made of a hard material including at least either cemented carbide or cermet. The Young's modulus of the hard material is between 300 GPa and 400 GPa. The Vickers hardness (Hv) of the hard material is 800 or more.

An assembly and method of forming a press cutting die that includes a cutting blade that is supported by a blade support assembly or blade support. The blade support includes a first base portion and a second base portion that are each contoured to cooperate with one another to capture a portion of the cutting blade along an interface between the first and second base portions. Preferably, one or more keys extend between the first and second base portions and traverse the geometric plane associated with the cutting blade. Such a press cutting die is particularly applicable for cutting biologically compatible materials having a desired shape from a bulk source of the biologically compatible material.

Produced is an iron-based sintered alloy in which hard particles derived from a titanium carbide powder are dispersed in the form of islands in a matrix comprising a two phase structure of austenite+martensite. The iron-based sintered alloy is obtained by mixing the titanium carbide powder, a Cr powder, a Mo powder, a Co powder, a Fe powder and a powder of Al, Ti or Nb so as to obtain a mixed powder that contains, in terms of mass %, 20-35% of titanium carbide, 3.0-12.0% of Cr, 3.0-8.0% of Mo, 8.0-23% of Ni, 0.6-4.5% of Co and 0.6-1.0% of Al, Ti or Nb, with the balance Fe, and then subjecting the mixed powder to cold isostatic compression molding, vacuum sintering and solution treatment.

The disclosure relates to a cutting device which is adapted for cutting substantially round packaging corners from a film web, wherein the cutting device has at least one cutting tool comprising a cutting punch which has at its outside at least one concavity provided for forming a cutting edge of the cutting punch. According to the disclosure, the cutting edge has a cutting contour extending both transversely and longitudinally along the cutting punch. The disclosure further relates to a method for manufacturing a cutting punch.

A clamshell die press includes a fixed platen, a moving platen installed thereon a cutting blade, and a pad mounted on top of a working surface of the fixed platen, wherein the pad comprises a padding block, wherein the padding block comprises a padding layer composed of a material selected to match a tooth profile of the cutting blade.
