High-feed Face Mill Speeds Up Productivity



The CoroMill 745 cutter is now available in a high-feed version with a 25° entering angle.

Sandvik Coromant offers a high-feed version of the CoroMill 745 face milling cutter, featuring a 25° entering angle for additional productivity gains when milling steel and cast iron workpieces. It facilitates higher metal removal rates (MRR) in applications with depths cut up to 2.8 mm (0.110") in sectors such as die and mold, pump and valve, oil and gas, automotive, power generation and general engineering.

"Despite the elevated MRR and productivity, there is no compromise to surface finish when using the high-feed CoroMill 745," said a company spokesperson. A light cutting action from the innovative insert positioning provides enhanced chip formation, a smooth, soft sound and low power consumption.

"An important benefit of the cutter is low cost per edge from its double-sided, 14-edge insert design," said Matts Westin, Product Manager, Sandvik Coromant. "In fact, tool inventory costs are reduced because the CoroMill 745 with a 25° entering angle uses the same inserts as its counterpart cutter with a 42° entering angle."

The high-feed CoroMill 745 is aimed at roughing to semi-finishing face milling operations on machining centers and multi-task machines. With its multi-edge concept, the tool is particularly suitable for large batch production, flexible transfer lines and when maximum tool utilization is important. Advantages will be provided when milling components made from ISO P or ISO K materials, such as valves, engine blocks, hubs, main frames, pump components and molds, in fact, any type of general engineering component. The presence of a short (0.6 mm, 0.024") parallel land provides a good surface finish. The large screw provides easy handling, while the insert position and the heptagonal insert shape make clamping secure for reliable face milling operations. Internal coolant is available for all cutters that range from 63 to 160 mm (2.5 to 6.0").

"Providing an example of the potential gains on the offer, a customer trial application showed impressive benefits when face milling a machine bed component made from cast CMC ST52 (165 HB) on an ISO 50 gantry mill," said a Sandvik spokesperson. "A 125 mm (5") CoroMill 745 with a 25° entering angle reduced cycle time per component by 40% in comparison with a competitor tool."

The high-feed CoroMill 745 with a 25° entering angle complements CoroMill 745 with a 42° entering angle.
