High-Performance Face and Shoulder Milling

Sandvik Coromant CoroMill MF80

Sandvik Coromant has expanded its milling offering with the CoroMill MF80 for automotive milling applications in ISO K and ISO P materials in close to 90' operations with fixture constraints.

"Based on a technology platform similar to the existing CoroMill 345, this milling concept offers a 40% lighter cutter body with shim protection and a high number of inserts for secure and stable machining, even in vibration-prone overhang applications," said a company spokesperson. "The 89.5' approach angle enables the multiedge cutter to work close to the fixture, which not only improves machine utilization, but also ensures a longer tool life with less scrap."

The inserts have eight cutting edges, chip protection and optimized micro geometry for better security and chip evacuation, as well as a wiper edge for a enhanced surface finish. The cutting edge is inclined for smooth cutting action and low cutting forces, making it suited for thin-walled components and machine set-ups with limited stability.

"In a roughing shoulder milling performance test with a competing brand, the CoroMill MF80 showed a remarkable 67% increase in tool life, which, in turn, boosted overall productivity by 60%," said the spokesperson. "After 40 minutes of machining, the comparison ended with 15 freshly machined components for Sandvik Coromant and nine for the competitor. The shim protection and high number of insert edges effectively lowered cost per part in this roughing application."
