New style edge insert cutter for cast iron

The VOX400 face mill has primarily been designed with overall stability in mind, enabling it to cover a wide range of cast iron milling applications.

The design of the side-on or vertical insert allows the cutting forces to be absorbed through the whole length of the insert instead of through the far thinner face to face dimension..

This absorption of cutting forces has several knock on benefits for increased efficiency and versatility. It enables the maximum depth of cut to be greatly increased compared to conventional cutters. Fairly large depths of cut can also be achieved with standard methods, but this usually results in instability caused by vibration and lack of rigidity that compromises both component quality and tool life of the inserts. This example of extra depth of cut was seen to be beneficial when machining a customers' cast iron (GG40) press mould base, where the usual 5mm depth of cut could be doubled to 10mm at a cutting speed of 230 m/min with a table feed rate of 2050mm.
