Changing Spindle Position Using Quill Feed Levers
1.Unlock the quill lock lever and loosen the fine feed lock knob.
2.Pull down on any of the coarse downfeed levers to adjust the vertical position of the spindle. Observe the spindle height scale or digital readout to monitor movement in inches or millimeters.
Tip: Milling with the spindle fully extended can cause tool chatter. For maximum spindle rigidity when milling, it is better to keep the spindle retracted into the headstock as far as possible with the spindle lock and the downfeed selector knob tightened.
Changing Spindle Position Using Fine Feed Knob
1.Unlock the quill lock lever and tighten the fine feed lock knob.
2.Rotate the fine feed knob to lower or raise the spindle in small increments. Observe the scale on the knob or the digital readout to monitor movement in thousandths of an inch (Figure 27).
