A Widia milling carbide insert cutter supplied by Vargus Tooling UK us enabling a precision sub-contractor to achieve at least 30 per cent gains in metal removal rates and extended tool life.

During a like-for-like comparison with a competitor’s cutter of similar size and insert style, the CNC machinist applied the 125mm diameter Widia cutter at similar revs/min (400 rev/min) and at a 3mm depth of cut, and it achieved cycle times that were 30 per cent shorter that the former method.

In addition, by applying the Widia cutter at like-for-like maximum power available, feed rates were increased from 600 to 1000mm/min with a 30 per cent improvement in tool life.

The trials at the Telford-based company – a specialist supplier to the aerospace, automotive, food processing, gas and oil, hydraulic, marine and scientific industries – were carried out in conjunction with Castle Carbide, distributor for Vargus Tooling UK, Kennametal UK’s Widia master distributor in the UK and Ireland.
