2 Increased cutting speeds. Lower unit cost of production. Increased tool life. Lower production power requirements. Consistent machinability. Improved product surface grades will reduce wear on tools and extend tool lifeHighly abrasive inclusions which damage tools are excluded in the IM manufacturing Steel melt is a decrease in flank wear and crater wear of carbide tooling which results in: less dismounting and reassembling of tools; less adjustment time; and a noticeable improvement in the life of cutting Steel distributes Ugima Improved Machinability grades as its main product butalso other generic brands are machinability bar Chemical composition within ASTM standards.
