Graduated Index Rings

The table ball handles and elevation crank have graduated index rings attached (see Figure

18) that are used to accurately determine table movement in increments, as listed in the table below:

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

Index Rings

Figure 18. Graduated table index rings.

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 could result in personal injury or damage to the cutter and workpiece.

Table Locks

Refer to Figure 19 for the locations of the locks used to secure the table in place.
