1.装上模装在活塞孔中，下模装入开孔器支架中，放入要开孔的铁板(或不锈钢)。
2、按顺时针方向紧回油阀，然后反复按糍加王柄，使柱寒克开始T作、油压上升、上下模之间剪切增加，模具的工作上剪孔直到剪通为止。3、按逆时针方向松开回油阀，使工作缸的油退回，拿出落入下模具中的上模具。
上述3步操作程序就完成了开孔操作。
1.Up moulds was fixed in plunger hole. Down moulds was fixed in bracket of punching tools.
2.Tight oil valve from left to right then press handles time make piston pump work.Oi pressure up.up and down moulds enhence force until made to go though.3.Loose the oil valve from right to left, made the oil in cylider back, took the up moulds fromdown finish punching as above 3 steeps.
