To keep total control on their drives systems is one of the most critical points to ensure the performance of the most modern machine tools at their highest level. These drives, either linear or rotary, are the ones which make possible to position the tool and/or the workpieces quickly, accurately, and under control. The mechanisms which compose these systems of drive are generally classified according to their capacities of speed and acceleration, to the power which they are able to transmit, to their precision of movement, to their stiffness, their dimensions, and their reliability.
By design, the rack-and-pinion drive systems are offering, a better moment of inertia (lower), a higher natural frequency, a better efficiency and a total precision independent the length of the displacement. Not to mention that one of their biggest advantages is their versatility, especially in terms of flexibility on the installed length. The setting-up is faster and s...
