The ECOSPEED’s main spindle motor performance plays a key role in complex machining performances. Rated at 120 kW, it can run nonstop at 30,000 rpm in S1 mode – coupled with the machine’s high dynamic capabilities (acceleration of up to 1 g in all axes and jerk up to 200 m/s3). While roughing, the ECOSPEED F 1540 machine can fill a 55-gallon drum with chips in less than a minute.

Each of the ECOSPEED F machining centres features a Sprint Z3 parallel kinematic machining head, which boosts the machine’s ability for highly-dynamic, simultaneous five-axis/five-sided milling. The head uses three parallel linear axes drives mounted radially equally spaced in the headstock. The spindle platform is connected to each drive via rigid levers with a pivot at one end and a ball joint at the other. When all three axes move equally and simultaneously, the spindle is moved in a straight line in the Z-axis. If the three axes move differentially, the spindle platform will be tilted in the A/B kinematic, allowing the spindle to follow any path within a spherical cone of ± 45 degrees at a maximum of 80 deg./second. Each machine has an integral C-axis and is equipped with the automatically loaded and tool changeable right angle head, which operate at any spatial angle between ± 135 degrees. The ECOSPEED F 1540 machines “perform beyond our expectations,” said O’Neill. “No matter what the challenge. No matter the part. No matter the complexity of the part, Omni can now exceed their customers’ expectations.”
