Flat and round cutter and manufacturing method thereof

Abstract

The invention discloses a flat and round cutter and a manufacturing method thereof and belongs to the field of machining of cutters. The flat and round cutter comprises a center hole, a cutter head and a blade, wherein the center hole is located in the center of the cutter head, the blade is located on the outer ring of the cutter head, a cutting edge is arranged on the outer ring of the blade, the cutting edge angle delta of the cutting edge is in a range of 13-18 degrees, and threaded holes and mounting holes are formed in the cutter head. The flat and round cutter is manufactured from an alloy material comprising special elements under strictly controlled technological conditions through steps such as blank forging, isothermal spheroidizing, preliminary processing, heat treatment, rough grinding, leveling, tempering, deep processing and the like, the cutter has very high abrasion resistance while meeting the requirement for the sharpness, the service life is long, and the cutting edge is low in abrasion loss and free of cracking after long-term usage.

Description

technical field

[0001] The invention belongs to the field of cutter processing, and more specifically relates to a flat circular cutter and a manufacturing method thereof. Background technique

[0002] The flat round knife is one of the important parts of the slitter equipment. How to choose a slitting machine blade is determined according to the type and thickness of the slitting material. Generally, the slitting form of the slitter blade includes square knife slitting and round knife slitting. The square knife slitting is like a razor, the blade is fixed on the knife holder of the slitting machine, and the knife is dropped during the material running, so that the knife cuts the material longitudinally to achieve the purpose of slitting. There are mainly two ways of circular knife slitting: upper and lower disc knife cutting and circular knife extrusion slitting. Round knife slitting is the main slitting method for slitting thick film, composite thick film, paper and oth...
