DECI High speed spindles are high RPM, low torque devices. They use AC motors that provide constant torque up to base speed. Since power is equal to speed x torque, power increases as RPM increases. This type of spindle generally does not have high torque at low speeds. Typical low speed – high torque operations cutting more complex materials (think large face mills or roughing end mills) will not be well supported using most high speed spindles.
