Rotating Head

1.DISCONNECT MILL FROM POWER!

2.Loosen the four rotation lock bolts on the face of the head shown in Figure 24.

3.Use one hand to apply pressure to the head in the direction of tilt, then slowly turn the rotation bolt.

4.Re-tighten the lock bolts when you have the head in the desired position.

Tramming Spindle

After positioning the head at an angle and when your operation requires that the spindle axis be precisely perpendicular to the table, you must tram or align the spindle with the table to ensure the spindle is exactly 90° to the table.

This procedure involves mounting a dial test indicator to the quill or spindle, rotating it around the table, and adjusting the spindle AXIS :AXIS :ATO THE TABLE 8ANDT9AXESHAS illustrated in Figure 25.

and Y-axes.

We encourage you to research the many variations of spindle tramming to find the one that works best for you. If you do not already have a preference for performing this operation, use the following widely-used procedure for accurately tramming the spindle to the table.

Keep in mind that all workpiece top surfaces are not exactly parallel with the table top. You may choose to tram the spindle to the top surface of the workpiece after it is mounted instead of that of the table.
