Power chuck 350

3-jawair-operatedprecision

This is a standard model 350 (.0001 T.I.R.) gripping a gun part. This part is located on the outer face of the Offset tab. Therefore the part is loaded into the jaws, compressing the spring ejector. Then the cross-slide of the lathe moves into position and the chuck opens, pushing the part against a hard stop. The chuck re-clamps,and the part is hard-turned.
