Abstract
A coordinate measuring machine (10) having a vertically mounted probe (32), the weight of which is offset by an air counterbalance system (100). The air counterbalance system is adapted to use a source of air under pressure acting upon a piston (127) coupled to the vertically mounted probe (42). A torque converter (130) is mounted between the probe (42) and the piston (127) allowing the piston (127) to have a shorter travel than the allowable vertical travel of the probe (42). The air counterbalance system (100) preferably has components selected and arranged to minimize friction and weight to avoid distorting the precision of measurements on the coordinate measurement machine.
