CE
C. | Vernier Scale: Displays the |
| amount of table rotation with |
| a resolution of 10" (ten arc |
| seconds). |
D. | Rotation Scale: Displays the |
| table position in whole degrees. |
E. | Table Locks: When fully |
| tightened, keep 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. |
F. | Spindle Bore: Holds a center to |
| support a workpiece for dividing |
| work. Also, used in rotary table |
| alignment with the mill spindle |
| centerline. |

A.Handwheel: Rotates the table when the gears are engaged.
B.Handwheel Scale: Displays the amount of the table rotation with a resolution of 1' (one arc minute) and also in 1° marks. One complete revolution of the handwheel rotates the table 4°.
clockwise, the backlash |
adjustment ring disengages the |
gears so that the table can be |
rotated by hand. |
Note: The Model SB1368 uses |
a knurled ring instead of a |
