Milling/Drilling Mode Tapping Mode

This mill/drill is designed to use most end mills, drill bits, and face cutters that are 2" in diameter or less. The milling table has a coolant trough with drain for an optional cutting fluid system.

Failure to follow RPM and Feed Rate Guidelines may threaten operator safety from ejected parts or broken tools.

To mill a workpiece:

1. Refer to Control Panel on Page 20, and learn the how to use the machine controls.

2. Zero the spindle height scale and select units of measure.

3. Clamp the workpiece to the milling table, and adjust the headstock to the needed height, depth of cut, and milling path.

Remember: Milling with the quill fully extend- ed, can cause tool chatter. For maximum spindle rigidity, keep the spindle retracted into the headstock as far as possible with the quill lock lever locked and the fine feed lock knob tightened.

4. Refer to Calculating Spindle RPM on Page

22 to find the best spindle RPM.

5. Put on your safety glasses, turn the power switch ON, and press the START button.

6. Push the FORWARD or REVERSE button to select the appropriate cutting direction for the type of cutter that you are using.

7. Press the SPEED button to select the appro- priate milling speed for the diameter of cutter and type of material to be cut.

8. Use the X-axis or Y-axis handwheels to feed the workpiece into the cutter slowly. If you are only milling in one direction, lock the unused table slide in place. Refer to Table Travel on Page 19 for lock lever location.

This mill/drill is designed to change spindle direc- tion without stopping the spindle first. The wayed column allows for drill and tap changes and head- stock repositioning without loosing the tool reg- istration. Using the mill/drill in the tapping mode takes some level of skill, so make sure to practice using this feature. Avoid cutting threads in blind holes where the tap may bottom out and break before you can push the REVERSE button.

Failure to follow RPM and Feed Rate Guidelines may threaten operator safety from ejected parts or broken tools.

To drill and thread a hole:

1. Refer to Control Panel on Page 20, and learn the how to use the machine controls.

2. Zero the spindle height scale and select units of measure, and calculate your maximum tapping depth without bottoming-out the tap.

3. Clamp the workpiece to the milling table, and adjust the headstock to the needed height for drilling and tapping.

4. Put on your safety glasses, turn the power switch ON, and press the START button.

5. Drill your hole with the appropriate speed and drill bit size for the tap. For large holes you may have to drill a pilot hole.

6. Install the tap, and apply tapping fluid or oil when needed.

7. Push START, then the TAPPING button, and then the SPEED button. The safest tapping speed is 100 RPM.

8. Begin threading, but without disengaging the threads, frequently push the FORWARD and REVERSE buttons on the downfeed handles to cut and back-out the tap to eject the chips from the hole and prevent thread galling.
