Rolling processing of small holes
In order to process the XT-10 workover rig and the liquid (?) rotary joint installed on the imported step-up crane (Figure 1). We have designed a special tool for rolling (Figure 2). When rolling, the Morse taper shank is placed in the taper hole of the lathe of the lathe, and the hand wheel can be rolled to leave a hole with a hydraulic residual of 0.01 to 0.02 mm after turning. Rough finishing can be done in one setup, after the original turning
