Replace expensive, complex indexable tungsten carbide or PCD milling cutters in high volume production finishing applications.
The flat machining of bi‐metal surfaces or milling applications involving an interrupted cut can present daunting challenges to PCD or carbide milling cutters. The inserts may chip during the milling process, resulting in high machining costs and elevated levels of sub‐standard or rejected parts. The Engis ElectroMill is designed to produce high quality, flat milled surfaces, even if an interrupted cut is present or multiple materials need to be machine simultaneously.
The ElectroMill, combined with high pressure coolant, can machine these materials to an extremely accurate value of flatness with very low tooling costs. On cast iron flatness of up to 20 µm and surface finish as smooth as 8 Ra over a single continuous length have been achieved. In some cases customers have been able to reduce scrap and reworks significantly; this contributes to increased productivity and an improved bottom line.
Significant advances in part quality, as well as cost savings, have been realized with the use of the ElectroMill in the final machining of cast iron hydraulic valve bodies and aluminum engine blocks fitted with cast iron cylinder inserts.
