Abstract
A railvice for use with a wire EDM, milling machine, or boring machine, having an elongated rail through which a T-slot extends longitudinally. A locking member of the railvice sits in the T-slot. A jaw element of the railvice connected to the locking member by a bolt includes a cavity for the locking member. The locking member has bias forces acting upon it to force the locking member towards the bottom of the T-slot as well as along the T-slot. The bolt externally anchored with respect to the locking member is rotated to cause the bias forces acting on the locking member to assist in either locking the locking member in the T-slot or forcing the locking member to the bottom of the T-slot for movement of the railvice along the T-slot.
