This unit combines the advantages of simple indexer with those of a worm-geared indexer. When mounted on a milling, boring or other machine tool it can carry out single-purpose indexing and indirect indexing using the worm-drive mechanism.
Disengaging the worm drive the 24-notch master plate permits 2,3,4,6,8,12 and 24 dividing in the same manner as the simple index.
When the chuck is removed the unit can be used as a horizontal and vertical type rotary table. The operating handle to rotary table gear reduction ratio is 1:90.
