Sandvik Coromant's innovative QS holding system, already available for users of Citizen and Star automatic sliding-head lathes, is now being introduced for machine shops with Tornos, Tsugami and Nexturn sliding-head models. Released as part of Sandvik Coromant's CoroPak 10.1 phase of product introductions, the QS (Quick Start) system is a productive alternative to conventional toolholders, according to the company. With the QS system, tools can be slid in and out quickly, automatically locking into place on centerline, thus improving repeatability and accuracy thanks to its highly secure positioning in the tool post. The QS consists of a system of stops, wedges and short toolholders that replace conventional tool post hardware. The result is reduced downtime through faster tool changes. The following new QS components are available: QS wedges for Nexturn SA20 and SA26 machines; QS wedges and stops for Tsugami B0, BS, BU, BM, BN, BA and BW models; and QS wedges and stops for Tornos Delta 12 and 20 machines. Toolholders are available to suit CoroTurn 107, CoroCut 1, -2, -3, CoroCut XS and CoroThread 266.
