Cemented carbide Taps Cutting & Applications - Part 2

Thin layer cutting

The cemented carbide taps of the multiple blade forming the cutting structure, so that its respective cutting teeth of the cutting layer of small thickness, only a dozen of microns to several hundred microns, belonging to the thin layer cut areas. Cemented carbide taps other tool, the cutting edges are inevitably there is a tiny arc cutting thickness and edge radius close weakened, increased compression, resulting in the cutting force and cutting heat than high. Especially after cemented carbide taps with blunt or chipping defects, cutting force will increase sharply, the rapid loss of use features. Cemented carbide taps production, on the one hand the need to improve the grinding quality, reducing the corner radius; the other hand, we must strictly control the heat treatment of grain size of the material, to improve the toughness and strength, a tendency to reduce chipping.
