With the Sandvik Coromant Coroturn QS Quick Start system, changing toolholders at the gang toolpost on a Citizen CNC sliding-head turn/mill centre can now be performed in just 20 secs, with the position of the cutting edge of the insert automatically set by the toolholder against a dead stop and therefore not requiring any additional adjustment.
The new Coroturn QS Quick Start system uses a spring-loaded wedge to locate the shorter than normal toolholder shank against a set dead stop in the gang tool post of the machine. This is a major advantage as it replaces the conventional wedge locking system that requires three screws and a wedge clamp to captivate the toolholder.
