High pressure coolant and additional Capto sizes for CoroTurn HP

The coolant jets of CoroTurn HP improve machining performance by delivering cutting fluid at the point of cut, thereby removing heat more efficiently and reducing subsequent problems of accelerated wear. The technology also helps eliminate chips re-machining by keeping the cutting zone free of removed material, thus reducing the potential for component damage and supporting the unmanned operations. This is particularly relevant when using multi-task turn-mill centres where chips gathering around the tool cause problems for automatic tool changing. Negative style inserts are often preferred when machining difficult materials, such as heat resistant super alloys (HRSAs), titanium and stainless steel. But a lack of suitable easy-to-index toolholding technology featuring integrated high pressure coolant delivery has, until now, left a number of manufacturers, in industries such as aerospace, motorsport and medical, in a difficult position. Sandvik Coromant has extended the CoroTurn HP range with the introduction of a further 38 new toolholders in C5, C6 and C8 Coromant Capto coupling size, which are designed to accommodate negative inserts in C-, S- and D-styles. According to Sandvik Coromant, the new toolholders can offer up to 20 per cent increase in cutting speed when roughing difficult materials, and up to 50 per cent more tool life when roughing or finishing challenging workpiece materials. CoroTurn HP is a pioneering coolant system, which when combined with the accurate, quick-change Coromant Capto system, harnesses high pressure capability up to 80 bar in turning centres, vertical turning lathes and multi-task machines.
