Applications of this type have traditionally presented challenges to PCD or carbide cutters as the inserts can potentially chip during the milling process, resulting in high machining costs and elevated levels of sub-standard or rejected parts, says the company.
With its high stock removal rates, cool cutting action and extended tool life compared with conventional milling cutters, the ElectroMill ensures reduced tooling costs, Engis says, while at the same time offering environmental benefits due to its ability to be used with water soluble or synthetic fluids. Other advantages include the integration of industry standard adapter mountings and milling cutter dimensions.
Applications include the finish-machining of cast iron hydraulic valve bodies or aluminium engine blocks fitted with cast iron cylinder inserts.
