The CoroMill 316 from Sandvik Coromant is an exchangeable head milling system that can be applied to high feed face milling, slot milling, helical interpolation, shoulder milling, profile milling and chamfer milling of components in material groups from ISO P to ISO S.
The system is available, as of March 2013, with internal coolant holes.
The machining of such materials as heat resistant super alloys, titanium and stainless steels often requires the use of coolant for temperature control and chip evacuation during cutting. Re-cutting of chips and chip jamming, often lead to poor surface quality, damage to the cutting edge and tool breakage. By offering an internal coolant solution, with precise positioning of coolant holes to optimize the effect of the coolant jet, CoroMill 316 is able to outperform existing solutions with external coolant, guaranteeing superior chip evacuation and a secure cutting process.
The CoroMill 316 system allows machine shops to quickly, easily and accurately switch between various operations such as cutter type, radius variation, teeth frequency, geometry and grade. CoroMill 316 end mills are even suitable for five axis milling of flanks which often require tapered tools for stability at longer tool reach.
