Toolholder system reduces automatic lathe set-up

Offered as a productive alternative to conventional tool holders used on Citizen 'Cincom' sliding head machines, a system provides a highly efficient, two step set-up to reduce downtime.

Sandvik Coromant has introduced a new 'QS' holding system as a productive alternative to conventional tool holders when used on Citizen 'Cincom' sliding head machines.

In comparison with the twelve steps required when changing conventional one piece tool holders, the new QS system offers a highly efficient, two step set up procedure to reduce costly downtime.

The single screw release design of the QS tool holder will reduce tool change times from 3 to 1 min, while the spring loaded wedges ensure quick and safe extraction and reduce the risk of dropping the holder.

Once in the machine, the insert edge position is automatically set by contact between the short holder and the stop.

Individual kits are optimised for best performance in specific machine types with toolholders available for front and back turning, parting-off, grooving and threading in 8mm, 10mm, 12mm and 16mm shank sizes for Citizen K, C, L and M-Series machines.

The highly secure insert edge position of the QS system will improve accuracy with 30% less movement when front and back turning, while tool holders for the system are available in a wide range of Sandvik Coromant tooling systems for best results.

The QS Holding System is set to become the standard on Citizen 'Cincom' machines and has been developed following an exclusive development programme between Sandvik Coromant and Citizen in Japan.
