Figure 7. Basic controls of the rotary table.
A.Handwheel: Rotates the table when the gears are engaged.
B.Handwheel Scale: Displays the amount of table rotation with a resolution of 1' (1 arc minute), and also has 1° marks. One full turn of the handwheel rotates the table 4°.
C.Backlash Adjustment Ring: Allows adjust- ment of the backlash between the gears. Also, disengages the gears so that the table can be rotated by hand. Loosen the back- lash adjustment lock, then rotate the ring clockwise until the worm gears disengage. Reverse the process to
D.Table Lock: When fully tightened, keeps the table from rotating to reduce the strain on the gears during operation. When cutting circular slots, a slight drag can be applied with the table locks to help reduce chatter caused by gear backlash.
