8.5 Basic milling procedure
The Mill-Drill is provided with a face mill cutter with
tungsten carbide inserts. Install cutter onto mill
arbor, and secure with socket cap screw and washer
(N and O, Figure 5-1). Install arbor into spindle using
procedure in
sect. 7.1 .
For best results, all milling operations should be
performed with cutter raised as close to head
assembly as possible.
1. Adjust depth stop to highest position.
2. Engage fine feed handwheel, and turn it to set
milling height.
3. Tighten spindle lock (F, Figures 8-1,8-2) at
desired height.
4. See sect. 7-3 for table movements.
Lock spindle in position before
attempting milling operations.
9.0 User-maintenance
Always disconnect power to
machine before performing maintenance.
Failure to do this may result in serious personal
injury.
9.1 General maintenance
1. After each use, wipe down machine with a clean
rag and apply light coat of oil to exposed metal
surfaces.
2. Periodically check for backlash, or “play”, in
table and head movements. If handles or
handwheels are turned an appreciable amount
before they seem to engage, or there is a
looseness in table or head movements, make
adjustments using gib screws. See
sect. 7.4.
3. Keep table and ways clean and free of debris.
Use a brush to clear shavings, not bare hands.
4. Make sure machine remains properly
lubricated. See sect. 9.3.
9.2 Additional servicing
Any additional servicing should be performed by
authorized service personnel.
