A modular vise system for holding working objects. The system includes a fixture plate and an adjustable vise member for coupling the working object to the fixture plate. The adjustable vise member is configured to locate and secure the working object in relation to the fixture plate. The adjustable vise member includes a body, a moveable assembly, and a gripper. The body has a fastener configured to allow the body to selectively translate relative to the fixture plate. The body has a cavity formed within it. The moveable assembly is housed at least partially within the cavity of the body and configured to selectively translate relative to the body, thereby allowing further precision locating of the working object. The gripper is configured to secure the working object. The gripper is coupled to the moveable assembly.
