The horizontal and horizontal levels of the machine should not exceed 0.21004.2.1. Measure the verticality between the moving and fixed templates. When the mold is closed, the shooting head is in the original position. As shown in Figure 1, place the 7-foot-tall moving and fixed templates on the bracket and install the dial indicator on the special seat: the dial indicator seat is placed on the flat ruler, and the measuring head is placed on the shooting plate to measure the difference between the smallest number on the dial and the smallest number on the plate, which is the parallelism between the moving and fixed templates. Figure 1
4.2.2 1. Measure the verticality between the moving mold and the moving plate. When the mold is closed, the shooting head is in the original position. As shown in Figure 1 , at the head of the shooting plate, teach the angle ruler: JA/T1014799
bracket: the table gauge, support the fixed template and the movable template to move, so that the head of the gauge is set to the required point along the angle ruler before the required expansion: the maximum value of the maximum reading of the gauge is the vertical value between the shooting plate and the fixed template or carbon plate. Figure 2
4.2.3 Determination of the verticality between the movable template and the fixed template When the plate is in the mold state (not shown), as shown in the figure: install the gauge on the bracket with a semi-base surface, and move the fixed template. The probe slides on the movable template to measure the parallelism. The difference between the maximum and minimum readings of the percentage gauge is the parallelism value between the movable template and the fixed template.
