Sandvik Coromant now offers high feed CoroMill 745 face-milling cutter

Cutting tool and tooling system specialist Sandvik Coromant has unveiled 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. The previous system has a 42° entry angle.

The new high feed version supports higher metal removal rates (MRR) in applications with depths of cut up to 2.8 mm. The new cutter will offer benefits to those involved in work such as die and mould, pump and valve, oil and gas, automotive, power generation and general engineering.

The cutter is aimed at roughing to semi-finishing face-milling operations on machining centres 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 utilisation is important. Advantages will be seen when milling components such as valves, engine blocks, hubs, main frames, pump components and moulds, in fact, any type of general engineering component made from ISO P or ISO K materials.

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

The presence of a short (0.6 mm) parallel land ensures a good surface finish. The large screw ensures easy handling, while the insert position and the heptagonal insert shape make clamping exceptionally secure for reliable face milling operations. Internal coolant is available on all cutters, which range from 63 to 160 mm.

Says Matts Westin, product manager at Sandvik Coromant: “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.”

Providing an example of the potential gains on offer, 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° entry angle reduced cycle time per component by 40%, in comparison with a competitor tool.
