Brushless Electric Motor Spindle

Designed for high speed milling, drilling and other applications, NSK America Corporation’s E3000 electric motor spindle is available in 20-mm, 25-mm and 30-mm diameters. Featuring accuracy within one nanometer, the brushless spindle features as many as 350 W of power and 9cN-m of torque. As many as four spindles can be controlled individually when interfaced to the CNC with a selector unit. The shorter design is useful for Swiss-type, standard and specialty machines, the company says.
