13Emergency stop (M). Push to stop all machinefunctions. To restart, rotate E-stop button clockwiseuntil it disengages. Note: It is recommended thatstart/stop button (N) be used for normal spindlestoppage to prevent unnecessary wear on E-stop.Spindle start/stop (N). Activates spindle rotation.Spindle speed (O). Sets spindle rotation speedwithin the pre-selected range.8.2 Powerfeed operationTurn machine OFF beforeselecting speed and initial powerfeed settings.Failure to comply may damage gear mechanism.See Figures 8-1 and 8-2.1. Turn off machine – spindle stopped.2. Disengage spindle lock (C).3. Select appropriate spindle speed range (D).4. Select downfeed rate (F).5. Loosen handle (A 2 ) and rotate collar (A 1 )counterclockwise to desired depth on scale.OR… lower spindle to desired depth and setcollar (A 1 ) to zero on scale.6. Tighten handle (A 2 ) to secure setting.7. Loosen powerfeed disengagement knob (G).8. Turn on spindle and adjust speed dial (O) todesired RPM.9. Pull downfeed handle (B) away from head toactivate power downfeed.10. Once downfeed has reached pre-set depth, thetrip will release and spindle will retract.11. To stop feed before cycle has ended, pushhandle (B) toward head.NOTE: Set downfeed dial (F) to “0” when not usingpowerfeed.8.3 Manual coarse feedSee Figures 8-1 and 8-2:1. Turn off machine – spindle stopped.2. Disengage spindle lock (C).3. Set feed rate to “0” on dial (F).4. Select spindle speed range (D).5. Set drill depth (A 1 /A 2 ).6. Tighten powerfeed disengagement knob (G) toprevent auto downfeed engagement.7. Turn on spindle and adjust speed dial (O) todesired RPM.8. Engage workpiece using downfeed handle (B).Feed will stop at preset depth.8.4 Manual fine feedSee Figures 8-1 and 8-2:1. Turn off machine – spindle stopped.2. Disengage spindle lock (C).3. Set feed rate to “0” on dial (F).4. Select spindle speed range (D).5. Set drill depth (A 1 /A 2 ).6. Turn on spindle and adjust speed dial (O) todesired RPM.7. Pull handle (B) into powerfeed position.8. Turn fine feed handwheel (E) to accomplishoperation. Fine feed scale is 0.001 inchgraduations. If depth reaches pre-set stop, finefeed will disengage and spindle will retract.CAUTION: Downfeed handle (B) will rotateduring retraction.NOTE: To disengage fine feed at any time duringoperation, push handle (B) toward head.8.5 Tapping procedure (45VSPFTonly)Use one of the above methods to first bore the pilothole. IMPORTANT: Appropriate tap feed/speed isdetermined by multiple factors, such as workpiecematerial, drill size and type of tap. Consult amachinist’s handbook or the tap manufacturer forspecific recommendations.1. Turn off machine – spindle stopped. Insert tapinto chuck.2. Disengage spindle lock (C).3. Select tapping mode (K) and set feed rate (F) to0.001.4. Select low speed range (D).5. Set depth scale (A 3 /A 4 ) to desired stop. Makesure scale ring system (A 1 /A 2 ) has been set tozero to prevent interference with downfeed.6. Turn on spindle and adjust speed dial (O) to lowRPM.7. Pull handles (B) into powerfeed position. Whentap reaches selected depth, spindle will reverseand retract tap from hole.8.6 Basic milling procedureThe Mill-Drill is provided with a face mill cutter withtungsten carbide inserts. Install cutter onto millarbor, and secure with socket cap screw and washer(N and O, Figure 5-1). Install arbor into spindle usingprocedure in sect. 7.1.For best results, all milling operations should beperformed with cutter raised as close to headassembly as possible.
