    Manual pulse generator to move the relevant axis (X, Y, and Z), (hand pulse rate set at 1 × 100 of the gear, that is, each change of step motor input to 0.1mm), with the dial indicator to observe the relevant axis movement. china bearing companyUnidirectional motion accuracy to maintain normal forward movement as a starting point, hand pulse changes every step, the axis of movement of the machine the actual distance d = d1 = d2 = d3, ... = 0.1mm, motor runs good, good positioning accuracy.bearing company Return on the actual machine motion displacement changes can be divided into four stages: (1) machine movement distance d1> d = 0.1mm (slope greater than 1); (2) show d = 0.1mm> d2> d3, (slope less than 1); the â'¢ Machine Tool not actually move, showed the most standard backlash; â'£ machine movement distance and hand pulse to the value equal to (slope equal to 1), back to the normal movement of the machine.bearing manufacturer
