Table Movement, Graduated Index Rings | Grizzly G0747 and G0748

Models: G0747 and G0748

Table Movement

The mill table moves in three directions, as illus- trated in Figure 16:

•X-axis (longitudinal)

•y-axis (cross)

•z-axis (vertical)

These movements are controlled by table ball handles and the Z-axis crank. Additionally, the table can be moved along the X-axis with the power feed.

Graduated Index Rings

The table ball handles and knee crank have grad- uated index rings (see Figure 17) that are used to determine table movement in the increments listed below:

Axis	Individual	One Full
Axis	Increment	Revolution
	Increment	Revolution
X	0.001"	0.200"
Y	0.001"	0.200"
Z	0.001"	0.100"

Table Locks

Use table locks to increase the rigidity of the table when movement in that direction is not required for the operation.

Refer to Figure 18 to identify the locks for each table axis.

Always keep the table locked in place unless table movement is required for your operation. Unexpected table and workpiece movement could cause the cutter to bind with the workpiece, which may ruin the cut- ter or the workpiece.
