Starrag tackles titanium with new Scharmann Ecoforce Ti machining centres

Starrag has expanded its range of machines for titanium machining with the introduction of the Scharmann Ecoforce Ti horizontal machining centres covering X, Y and Z axis capacities up to 6,300 mm by 3,000 mm by 3,000 mm and featuring three-axis roughing head and/or five-axis fork-type head for finish machining.

These new models align with the Starrag philosophy of guaranteeing the consistent highly-efficient production of high-quality parts – in this case specifically to satisfy the aerospace industry's increasing demands for the cost-effective machining of titanium.

The new machines combine the renowned construction capabilities of Starrag group companies' expertise in vertical table design and jig boring column accuracy to result in a machine range that excels in levels of rigidity and machining accuracy.

In addition, a wide range of machining flexibility is offered via automatic head changing possibilities and the use of high-capacity tool magazines.

Ecoforce Ti 2040/2540 models feature X, Y and Z axis travels of 4,300 mm by 2,500mm/3,000 mm by 3,000 mm, while the 2060/2560 models have a respective X axis capacity of 6,000 mm and similar Y and Z traverses.

Workpieces weighing up to 8,000 kgs and 10,000 kgs can be accommodated on the 2040/2540 models; and 12,000 kgs and 15,000 kgs on the 2060/2560 series.

In all cases the machines boast X, Y and Z rapid traverse rates of 20 m/min and HSK B 160 toolholders. The 50 kW fork-type milling head, which develops 10 to 3,000 revs/min and a torque of 2,400 Nm, is complemented by a 75 kW spindle extension rated at 3,000 revs/min and 5,500 Nm.
