High-feed face mill speeds production Featured

Sandvik Coromant has unveiled a new high-feed version of its CoroMill 745 face milling cutter, featuring a 25° entering angle for additional productivity gains when milling steel and cast iron workpieces. The high-feed version facilitates high metal removal rates (MRR) in applications with depths of cut up to 2.8 mm.

Despite the elevated MRR and productivity, there is said to be no compromise in surface finish. A light cutting action provides good chip formation, a smooth, soft sound and low power consumption.

An important benefit of the new cutter is low cost per edge from its double-sided, 14-edge insert design. In fact, purchasing departments will be pleased to learn that tool inventory costs are reduced because the CoroMill 745 with 25° entering angle uses the same inserts as its counterpart cutter with 42° entering angle.

The high-feed CoroMill 745 is aimed at roughing to semi-finishing face milling operations on machining centres and multi-task machines. The presence of a short (0.6 mm) parallel land is designed to ensure a good surface finish. Furthermore, internal coolant is available on all cutters, which range from 63 to 160 mm.

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