SAFETY
To prevent serious bodily injury, you should observe the following basic safety precautions when
installing, operating or servicing the milling machine.
1. Follow all instructions in the manual.
2. Wear approved industrial safety glasses and safety shoes.
3. Do not wear gloves, long sleeves, long hair, rings, watches, jewelry or other items that could
become caught in moving parts.
4. Keep all parts of your body away from moving parts (belts, cutters, gears, etc.)
5. Use proper point of operation safeguarding.
These and other safety precautions are discussed in the American National Standard Institute
standard entitled safety requirements for the construction, care, and use of drilling, milling, and
boring machines (ANSI B11-8-1983).
This publication is available from:
American National Standards Institute
25 West 43rd Street, 4th floor
New York, NY 10036
Safeguarding for protection at the point of operation can only be designed and constructed when
the parameters of the particular operation have been determined. As a result, ANSI B11.8-1983,
Section 5.1, states that “it shall be the responsibility of the employer to provide, and ensure use of, a
guard, guarding device, awareness barrier, awareness device, or shield…”
To assist machine users in designing point of operation safeguarding for their specific machine
applications, the Occupational Safety And Health Administration has published a booklet entitled
Concepts and Techniques of Machine Safeguarding (OSHA Publication No. 3067).
This publication is available from:
The Publication Office – OSHA

iv M-508
INSTALLATION AND USE OF SAFEGUARDS
Both American National Standard B11.8 and OSHA Section 1910.212 assign responsibility for
point of operation safeguarding of milling machines to the employer/user. Therefore, to prevent
serious injury resulting from the rotating cutter, flying chips, or splashing coolant, point of operation
safeguarding should be used on milling machines to the greatest extent practicable.
This booklet provides basic information for the installation and use of the general purpose
safeguard. It also contains the names of several manufacturers of other types of point of operation
safeguarding for vertical milling machines.
Remember, point of operation safeguarding is your responsibility as the employer/user. You are in
the best position to evaluate your safeguarding needs and ensure that the proper safeguards are
installed and used.
- CAUTION -
A safety shield is supplied for protection from chips and coolant with every
machine.
The chip and coolant shields have been designed and are custom manufac
tured with the highest clear impact material commercially available:
polycarbonate (G.E. Lexan). It has an impact strength 5 to 10 times greater
than acrylic (plexiglass) or butyrate (UVEX) materials, thereby offering the
greatest protection for our customers.
Some of the new “easy to dispose of” coolants and/or cutting oils contain
chemicals harmful to polycarbonate. These chemicals are:
Mono-ethanolamine, Di-ethanolamine, Tri-ethanolamine and the combination
thereof. These chemicals may significantly reduce the impact strength of the
shield within days, and could destroy the entire shield in weeks.
Use of use of coolants and/or cutting oils containing these chemicals will
void the warranty on your safety shield, and could cause injury to your workers.
- WARNING -
This safeguard DOES NOT take the place of any other safety practice or
safety equipment.
YOU MUST ALWAYS wear safety glasses and safety shoes.
YOU MUST ALWAYS stop the spindle of the machine completely before
changing or adjusting the workpiece, fixture, or tool.
-
YOU MUST NEVER wear gloves, long sleeves, long hair, rings, watches,
neckties, jewelry or other loose items.
M-508 v
GENERAL PURPOSE SAFEGUARDS
There is no single safeguard which can match the versatility of the Series I machine. As a result,
you will find that the guard assembles shown in Figures I.I and I.II, like all safeguards, will be suitable
for some operations, but not for others. Carefully analyze the operation to be performed before
deciding whether this safeguard is suitable. Adjust the safeguard to suit your special requirements. If
you find that it is not suitable for a particular application, you should use an alternate form of
protection.
Installation for Machines with R-8 Spindle Taper
There are two tapped holes in the nose cap of the spindle to be used for mounting the guard (the
two untapped holes serve to remove the nose cap with a spanner wrench).
1. Place the mounting ring (Item 11) underneath the top of the guard (Item 7).
2. Place two socket head cap screws (Item 12) through the holes in the ring, and hand-start them
into the threaded holes in the nose cap until hand tight.
3. Align guard to be square with table of machine (unless angular mounting is desired).
4. Tighten screws with a hex Allen wrench.
