Grizzly Mastering the Dial Indicator: Table Travel and Feed Controls Explained

Table Travel

The mill/drill table moves in the longitudinal (X-axis) and cross (Y-axis) directions.

Longitudinal Feed

The handwheels shown in Figure 42 at each end of the table move the table longitudinally (X-axis). These handwheels will move the table in both directions. One complete revolution of either handwheel moves the longitudinal feed 0.100". A scale on the front of the table is used when a high tolerance is not required. The table locks located on the front of the table, shown in Figure 43 lock the table in position longitudinally. Use these when performing operations that only require cross slide movement.

Cross Feed

The cross handwheel shown in Figure 42 move the table along the cross axis (Y-axis). One complete revolution of the handwheel moves the cross slide 0.100". The table lock lever located on the right side of the cross slide underneath the table, shown in Figure 43 locks the table in the cross direction. Use his lock when perform- ing operations that only require longitudinal table movement.

Graduated Dials

The graduated dials (Figure 44) on the handwheels for the table and fine feed can be indexed or “zeroed” to help make accurate and convenient movements. Each dial can be reset or locked with the thumbscrew attached to it.

Example:

Suppose you want to drill a series of holes in a workpiece at 0.625" centers. After locating and drilling the first placement, you can set the dial of the appropriate axis to zero while holding the handwheel. Move the table 0.625". Drill the next hole and proceed as above.
