Quality cutting machine flow epidemic adjustment general rules
Drill flat before changing the thread. Use water drill diameter
3.! But when using the standard, the adjustment shall follow the relevant provisions of JB2?C. The amount of surprise depends on the previous installation plan 1 and other parts of the air permeability temperature change, pick up the test method and test two on the right
3.2 black JB3670-82 3.1 adjust the installation level, put the fire on the working surface level ruler, the water meter in the weaving direction and the inspection direction of the reading efficiency shall not exceed 0.10/000.
3.3 During the inspection, the general Sichuan control transfer inspection: the original and number signatures are convenient for arranging the actual comprehensive position and optimal sequence. 3.4\ When the actual measured length is different from the length specified in this standard, it should be converted according to the length that can be measured by the existing technology in 2.3.1.1 of Beijing 267℃82. When the converted result is less than .m, it should be calculated. 3.5 The operating plane referred to in this standard refers to the true plane passing through the main axle load and the axle point, which can be the vertical plane or the horizontal plane passing through the side average line.
3.6 The length is designed by the user manufacturer, and the calibration items can be reduced. Machinery City Industry Department 19781 approved
