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:

M-450A

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 manufactured 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.

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 assemblies 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 guard 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

If the machine was manufactured on or after January 1, 1983, the manufacturer has drilled and tapped two 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 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 wrench.

Retrofits

If the machine was manufactured prior to January 1, 1983, you must retrofit as follows:

1. Manually tap the existing spanner wrench holes with a .250”-20 bottoming tap.

- CAUTION -

There is no need to drill new holes or deepen the existing holes. Attempts at either practice may result in spindle damage.

2. Mount the guard as indicated above.

Machines with Erickson #30 Quick Change or Universal #200 Quick Change Spindles

If the machine was manufactured after January 1, 1985 and has either an Erickson #30 or a

Universal #200 quick change spindle, the manufacturer has drilled and tapped four #8-32 holes in the nose cap of the spindle for mounting the guard.

ERICKSON SPINDLE

1. Remove the spindle locknut. This is done by removing the long button head black finish screw, which is normally left of the cadmium-finished button head screw on the locknut of the spindle.

This will allow you to unscrew the locknut by turning it counter-clockwise.

- NOTE -

Observe the orientation of the mounting holes in the spindle and the mounting ring to orient the quill guard as desired.

2. Place the mounting ring (Item 11) on the top of the guard (Item 7).

3. Place the locking ring (Item 12) underneath the top of the guard (Item 7).

4. Secure the two rings together with four #8-32 x 5/8 button head cap screws.

5. Lower the quill.

6. Position the guard under the spindle.

7. Use four #8-32 x 1/2 button head cap screws to secure the guard to the spindle.

8. Reinstall the quick change locknut. Refer to assembly instructions.

UNIVERSAL #200 QUICK CHANGE SPINDLES

The quick change locknut is not to be removed. To install the spindle safeguard, follow the preceding steps listed above: 2, 3, 4, 5, 6, and 7.

FOUNDATION

PLACING ON A SOLID FOUNDATION

When setting machine on a concrete foundation, it is advisable to use a little grout (thin mortar) to take care of any unevenness in the concrete as well as to provide a solid foundation at all points.

When setting machine on a floor than has any surface irregularities, shims should be used to correct this condition to the greatest extent possible.

- NOTE -

It is recommended that the machine be secured to the floor to prevent movement or tipping due to off-center loading.

Before securing machine to floor by tightening hold-down bolts, make certain that all four corners are making contact with the floor after machine is leveled. If above condition is not met, it is possible to twist the column and put a bind into the ways.

Ideally all milling machines should be bolted to a concrete foundation. The machine should be placed on a solid level floor with shims or anti-vibration pads as shown in Figure 1.6 to insure machine base is positioned evenly.

RECOMMENDATIONS:

Use 2, 3 or 4 end mills. Eight-flute end mills are usually not satisfactory for general milling. When using shell mills, face mills or any other tooling, proper machining practice should be observed.

Power feed can be used for drills up to .375”

Æ

. Use manual feed for drills larger than .375”
