M1110 Mill with Dovetail Column

Milling/Drilling

This mill 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
a drain for an optional cutting fluid system.
Failure to follow RPM and feed rate guide-
lines may threaten operator safety from
ejected parts or broken tools.
To mill a workpiece, do these steps:
1. Refer to Control Panel on Page 19, and
learn how to use the machine controls.
2. Zero the spindle height scale on the spindle
feed hub.
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
extended can cause tool chatter. For
maximum spindle rigidity, keep the spindle
retracted into the headstock as far as pos-
sible with the quill lock lever locked and the
fine feed lock knob tightened.
4. Refer to Calculating Spindle RPM on Page
20 to find the best spindle RPM.
5. Put on your safety goggles, turn the main
power switch ON.
6. Select the FORWARD or REVERSE with the
FWD/REV dial to select the appropriate cut-
ting direction for the type of cutter that you
are using.
7. Turn the high/low shift knob and the spindle
speed dial to select the appropriate 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 15 for lock lever location.

Tapping

This mill is designed to turn very slowly for
through-hole tapping operations. The wayed col-
umn allows for drill and tap changes and head-
stock repositioning without losing the tool regis-
tration. However, tapping with any mill without
a slip clutch takes some level of skill. Avoid cut-
ting threads in blind holes where the tap may
bottom out and break before you can stop and
reverse the spindle.
Failure to follow RPM and Feed Rate
Guidelines may threaten operator safety
from ejected parts or broken tools.
To drill and thread a hole, do these steps:
1. Refer to Control Panel on Page 19, and
learn how to use the machine controls.
2. Zero the spindle height scale on the spindle
feed hub, and calculate your maximum tap-
ping 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 goggles, turn the main
power switch ON.
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. Begin threading.
