Coroturn HP turning tool holders
Sandvik Coromant has extended its Coroturn HP range of turning tool holders with an integrated high-pressure delivery capability.
The coolant jets of Coroturn HP improve machining performance by delivering cutting fluid at the precise point of cut, thereby removing heat more efficiently and reducing the subsequent problems of accelerated wear, according to the company.
The technology also helps to eliminate the re-machining of chips by keeping the cutting zone free of removed material, thus reducing the potential for component damage and permitting the scheduling of unmanned operations.
This is particularly relevant when using multi-task turn-mill centres, where chips gathering around the tool cause automatic tool change problems.
Negative-style inserts are often preferred when machining difficult materials such as heat-resistant super alloys (HRSAs), titanium and stainless steel.
Indexable tool-holding technology featuring integrated high-pressure coolant delivery could help machine shops improve chip breaking, tool life and/or cutting data.
Sandvik Coromant's current tool-holder programme has now been increased with the introduction of a further 38 tool holders in C5, C6 and C8 Coromant Capto coupling sizes, which are designed to accommodate negative inserts in C, S and D styles.
According to the company, the new tool holders can offer up to a 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.
When combined with the quick-change Coromant Capto system, the Coroturn HP coolant system harnesses a high-pressure capability of up to 80bar in turning centres, vertical turning lathes and multi-task machines.
To optimise steel machining processes, Sandvik Coromant has developed GC4305, an insert that offers both high metal removal rates and stable conditions.
This catalogue is designed to speed up the identification and selection of tools, adapters and accessories that address the challenges of today’s parting and grooving machining operations.
Today, more and more areas of machining are benefiting from ongoing developments in high-pressure coolant technology. Operations such as turning, parting and grooving, for example, are seeing a welcome boost in performance, process security and quality. According to Sandvik Coromant, this is because coolant, applied at high pressure, is no longer simply a problem solver; it has become a productivity enhancer.
In the latest of a series of initiatives being developed around specific machining applications, Sandvik Coromant has released a free white paper dedicated to addressing the challenges of parting and grooving operations. The paper covers all aspects of parting and grooving and provides guidance, hints and tips in areas ranging from addressing the challenges caused by long overhangs to increasing both machine speed and tool life.
Sandvik Coromant has introduced a vibration damper that helps to maintain stable production during deep-hole machining (DHM) operations and to support increased machine tool utilisation.
