zerogage - Ball Arbors and Ball Chucks Ball Arbors and Ball Chucks
 
Design Guide (Zero Gage Applications)

1) Ball Arbors are used in gear rolling fixtures to check lead & involute.

4) Zero Ball Arbors precision locate the part. Zero Sweep Gages check bore locations.

2) Different bore dia's. are used to establish axis of part bores.

5) Zero Ball Arbor locates the part. Zero Sweep Gages check runout and cross hole location. (2) Diff. dia. bores are located.

3) Zero (Mechanically expanding) Ball Arbor establishes axis of part to be checked. For inspection use, in a built up fixture gage.

6) Zero Ball Arbor establishes center line.(5) part conditions are read on a single or multi column electronic instrument.
