A spool-fed grinding system includes a spooling system, a grinding machine, and a computer controller. The spooling mechanism includes a spool assembly from which wire is unwound, with the spool assembly having an axis of rotation on which a spool spins to unwind the wire. The grinding machine includes a grinding wheel, a linear movement mechanism, and a rotation mechanism. The linear movement mechanism holds and linearly moves the wire along a longitudinal axis during grinding, and the rotation mechanism rotates the wire about the longitudinal axis during grinding. The axis of rotation of the spool and the longitudinal axis generally are not transverse with each other. The computer controller is programmed to control coordinated operation of the spooling mechanisms and the grinding machine, such that the spooling mechanism is controlled to rotate the spool at a same rotation speed as a rotation speed of the wire during grinding.
