Coated cemented carbide tool for steel roughing applications and methods for machining |
摘要 |
A steel roughing grade coated cemented carbide cutting tool comprises WC grains equal to or less than 70 w/o of the tool substrate, from about 5 to about 10 w/o of a cobalt bonding phase and the remainder being metal carbide grains selected from the group TiC, TaC, NbC, HfC and combinations thereof. The average WC grain size is from about 0.9 to about 1.3 microns and less than 10% of the WC grains have a size less than 0.5 microns. The coated cemented carbide tool is coated with an adherent refractory coating layer. The coated cemented carbide cutting tool can be used to machine steel at rough and heavy rough cutting conditions.
