Description
ZFGB's 2 speed planetary inline, low backlash gearboxes remove the need for larger and more costly spindle motors and controls in machine tool main spindle drives.
Optimising the power of main spindle drives below their normal constant power range is a simple matter of downshifting with the 2 speed gearboxes, an operation which is now even faster and more efficient with the introduction of an improved solenoid gear changer.
