Sandvik Coromant has developed CoroThread, a 266 thread-turning tool that has precision over and under-coolant to help improve process security and maximise efficiency. The addition of over-coolant improves chip formation for more secure machining, while under-coolant controls temperature for long and predictable tool life, the company says. Precision coolant can also have positive effects on surface finish.
‘Process security and stability is paramount in thread-turning operations to ensure the machining of right-first-time threads, every time,’ said Hampus Olsson, product manager thread turning at Sandvik Coromant. ‘Along with precision coolant, this is why CoroThread 266 features the proprietary iLock interface between the holder and insert, which prevents cutting forces from causing micro-movements of the insert in the tip seat. In addition, for applications where long overhangs are unavoidable, the use of dedicated damped Silent Tools adaptors provide a proven way to reduce vibration and maintain precision.’
A wide standard assortment of insert thread profiles with dedicated grades and geometries is available for all materials, Sandvik says, while a tailor-made offer can be provided for an extended thread profile assortment.
