Starrag Group CO2 coolant development is award winner
Starrag Group's CO2 air cooling system won German magazine MaschinenMarkt's Award for Milling innovation at the EMO exhibition in Hanover, held last month.
Developed in conjunction with tooling giant Walter AG, the system can increase productivity levels on high-strength material workpieces, such as turbine blades, by up to 70%, while it can also double tool life, if cutting parameters remain unchanged.
The system is available for use on all Starrag machining centres, including those already in the field, as it can be retrofitted to existing Starrag machines.
The system sees liquid CO2 applied to the centre of the cutting tool via the machine spindle (at room temperature and without loss of pressure) to dissipate cutting temperatures and therefore minimise tool friction and swarf adhesion.
In addition, a second supplementary cooling channel (for aerosol or minimum quantity lubrication) can also be applied - the two media meeting at the cutting edge – for further improvements.
