Face mill provides high-feed capability Halesowen-based Sandvik Coromant (www.sandvik.coromant.com) has unveiled a high-feed version of its CoroMill 745 face mill featuring a 25deg 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 2.8mm.

According to the company, The new cutter is set to benefit sectors such as mould and die, pump and valve, oil and gas, automotive, power generation, and general engineering.

Despite the elevated MRR and productivity, there is said to be no compromise in surface finish when using the high-feed CoroMill 745.

The presence of a short (0.6mm) parallel land is designed to deliver a light cutting action that in turn 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.

Moreover, inventory costs can be reduced, because the CoroMill 745 with a 25deg entering angle uses the same inserts as its counterpart cutter with a 42deg entering angle.

The latest CoroMill 745 is aimed at roughing to semi-finishing face-milling operations on machining centres and multi-tasking 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.

Internal coolant is available on all cutters, which range from 63 to 160mm in diameter.

Providing an example of the potential gains on offer, a customer trial showed benefits when face-milling a machine-bed component made from cast CMC ST52 (165Hb) on an ISO50 gantry mill.

A 125mm CoroMill 745 with a 25deg entering angle reduced the cycle time per component by 40% in comparison with a competitor tool.
