Machines for aerostructures enhanced

Starrag UK has announced a host of improvements to its Ecospeed and Ecoforce machines – for aluminium and titanium aerostructure component machining respectively – to improve cutting performance in terms of both reduced cycle times and the consistent production of high-quality components.

The developments include: a more powerful spindle – 150 kW for the Ecospeeds – for even higher productivity; enhanced software routines such as optimised chatter control and adaptive jerk feed control on both Ecospeeds and Ecoforces; and new pallet options – on the Ecoforce Ti 9 and Ti 13 models – to accommodate ever-increasing workpieces sizes, particularly in structural aerospace components.

Starrag is also promoting cost benefits through the use of MQL as opposed to conventional flood coolant, with users obtaining at least three-fold savings, primarily through eliminating the need for coolant-related maintenance and recovery systems.

The use of MQL rather than conventional cutting fluid (on any machine in Starrag’s comprehensive range) is heavily promoted for aluminium machining, and it is suggested that if MQL is used at 100 ml/hour, 16 hours/day for six days a week and 50 weeks of a year, the total operating costs of €10,000 are far less than the €30,000 spent on conventional coolant. In addition, the difference in capital investment for the different systems is even greater.

The machines’ continual evolution is the result of constant investigations by Starrag’s expert product specialists and engineering teams into improvements that will enhance machine performance in the most cost-effective manner.
