Abstract
A machine tool, particularly a grinding machine, wherein one or more machine elements (such as a wheelhead, a table or a saddle) are movable along guideways in or on the machine frame. Each of the guideways is overlapped or shielded by a guard, and each guard is movable by a discrete prime mover in synchronism with the respective machine element so that the width of clearances (if any) between the guards and the respective machine elements remains constant. The provision of discrete prime movers for the guards ensures that the machine tool can treat workpieces with a higher degree of accuracy because the prime movers for the machine elements are not affected by the weight, inertia and/or other parameters of the guards.
