摘要： A coordinate measuring machine having a vertically movable probe shaft in which a vertical fine feed and lock mechanism for the probe shaft is provided by a first knob coupled to a magnet movable between two positions, one of said positions operatively coupling a second knob to the' probe shaft for driving said probe shaft in a vertical direction, the other of said positions being ineffective for moving the fine feed mechanism. The fine feed is accomplished throught the rotation of a second knob which is in frictional engagement through a driven quasi "V" shaped flanged wheel with the probe shaft to be moved vertically.

摘要： @ A coordinate measuring machine (10) having a vertically movable probe (41) supported from the bottom of a probe arm (42), the weight of which is offset by an improved pneumatic counterbalance (50). The pneumatic counterbalance is adapted to use a source of pressurized air acting upon a spherical piston (54) which is connected to probe arm (42). Spherical piston (54) fits with a close tolerance in cylinder (52). A rigid bracket (58) is connected to the top of probe arm (42). Piston rod (56) connects spherical piston (54) to a spherical bearing (53) in rigid bracket (58). A precision pressure regulator (70) having a relatively small capacity is provided to insure only a small change in the counterbalance force as the spherical piston (54) moves within cylinder (52). Regulator (70) is adjusted to provide make up air for the air which leaks past spherical piston (54).
