ABSTRACT:
A cutter driving apparatus has a spindle, a base, and a transmission shaft. The spindle has a cutter attached thereto. The base moves along the axis of the spindle. The spindle moves integrally with the base along the axis of the spindle. The base has a pair of support rods. The support rods are disposed apart from the spindle. The transmission shaft transmits a power to the base through the support rods so as to move the base along the axis of the spindle. This structure provides the cutter driving apparatus that facilitates boring operations by boring machines.
