DISK EXTERNAL-TYPE CUTTER AND CUTTING PLATE FOR IT

摘要

FIELD: mechanics, tools. ^ SUBSTANCE: proposed cutter comprises rotary cylindrical casing with its working part representing a flat ring. The casing working part surface and lateral sides have seats to fasten cutting plates thereon. Note that the cutting plate cutting edges are formed at intersections of faces on one of the opposite lateral sides of the cutting plate representing trapezoid with the upper and lower sides of the plate. Note that the cutting plate thickness is located along the cutter casing radius to allow using the cutting edge formed on the side of the plate acute angles for milling purposes. Note also that cutting plates fitted in seats arranged on the casing lateral sides features their thickness located along the cutter casing axial line to allow using the cutting edge formed on the side of the plate blunt angles for milling purposes. ^ EFFECT: reduced loads on cutter in cutting. ^ 6 cl, 17 dwg
