How to screw 3911-D Type Cams Scribed Line 1. Screw the cam (part 2) into the collet chuck (part 1), making Scribed Line of the cam the same level of the 1. 2. Screw the part 3 tightly along side of the part 2.
THE METHOD OF MEASURING 0269-5C COLLET CHUCKS 1. Check the runout of lathe spindle first. Adjust the runout value of nose within 0.004mm; of cylinder or taper within 0.004mm shown as follows. 2. Then put the 5C chuck onto the lathe spindle nose, with the setting hole at the right position to fix each other (While measuring, we used the screw lock device shown in picture-1. We did not have cam lock device shown in picture-2. They work theoretically the same, by different methods.) 3.
4. Approach the surface of the taper hole with a micron indicator; then rotate the measuring equipment slightly. Reading and noting the micrometer’s value. Tighten the one or two cam screws to correct the 5C fixture, until the runout value within 0.006mm. 5. Applying the standard 5C measuring bar, use two lock gears to tighten it slightly. And assure the run-out of the 5C fixture orifice, 0.015mm.
