Machine tool manufacturer Makino has released two new vertical machining centers designed for fast metal removal in aerospace applications.

The F8 and F9 vertical-spindle machining centers are constructed to perform high-precision operations on aluminam and titanium aircraft parts using high-power spindles and rigid tooling. The units ship with a 10,000 rpm spindle, or with an optional upgrade to a 20,000 rpm spindle, and take HSK-A100 tools from Haimer for heavy-duty applications, such as tempered or hardened steel.  The units can take drills as wide as 80 mm or milling cutter up to 125 mm in diameter for high-speed cutting at a 24m/mm feed rate.

The work envelope of the F8 and F9 is 800 mm in the Y axis and 800 mm in the Z axis. The F8 X axis operates within a range of 1,300 mm while the F9 X axis comprises 1,600 mm travel space.

Both spindles are constructed for vibration-damping while maintaining fast axis movements and rigid mechanical performance. The units also protect against overheating a thermal displacement with cooling technology that keeps the spindle in an appropriate range of head to maintain precision, and additional internal cooling technology that keeps the ballscrews, motor flanges, and bearing blocks cooled.

The machine tool design also enables the unit to cool down through inherent structural principles, rather than additional systems, electronics, and coolants.
