How to sharpen a high speed steel forming tool (arc cutter)?
：The grinding wheel of high speed steel is used in aluminum oxide grinding wheel (white), and the carbide tool head is made of silicon carbide wheel (green). Circular knife to open a big crumbs slot as knife rake Angle, remember the big can't grind was too deep, the Angle of uniform is to rely on his hands on the wheel to do arcs, general radius arc knife to be a little bit small not too big, or cutting power is too big
High speed performance is good, the technology of strength and toughness with good, so are mainly used for manufacturing complex thin blade and impact resistance of the metal cutting tool, also can produce high temperature bearing and cold extrusion mould, etc. Besides use produced by the method of high speed steel smelting, since the 1960 s and the powder metallurgy HSS, its advantage is to avoid the smelting production caused by carbide segregation caused by mechanical properties and heat treatment deformation.
Is the direct ground to need of high speed steel grinding Angle, can be appropriately increased his rake Angle, inclination Angle of blade, after grinding is very sharp, but turning slower
