MILLING-GRINDING-DRILLING AND SLOTTING ATTACHMENT
9-1 General Information
The milling-grinding-drilling and slotting attachment is commonly referred to
as a Versa-Mil. It is a compact, portable unit capable of doing many machining
operations that normally require expensive single-purpose machines. With the
different attachments that are available with the unit, drilling, shaping,
milling, and grinding can be performed quickly and inexpensively. This
self-powered, vertical-feed, variable-speed precision tool may be mounted in any
position on the carriage, table, ram, turret, or tool arm of other machine
tools. With a two-directional feed table, the Versa-Mil unit becomes a complete
machining tool for bench or in-place machining of parts too large to be moved or
held in conventional machine tools.
An important factor in the efficiency of the Versa-Mil is that machine tools
already in the shop area provide the power for feeds, a means of holding and
moving the work, and the rigidity needed for machining. Faced with unusual
machining problems, the Versa-Mil offers many solutions either as a separate
tool or combined with other machine tools and machinery already in the shop to
create special machines. The Versa-Mil increases the capabilities of standard
machines by doing secondary operations without changing setups. The Versa-Mil
provides power to interchangeable attachments allowing the unit to be used on
site to perform different machining operations on equipment being repaired or
rebuilt. Where space is limited, as in a shop area, floor space is needed only
for the lathe. Different sizes of the Versa-Mil unit are available for light,
medium, and heavy machining. This chapter will be limited to the Series 31
(light machining unit).
Safety in the shop area or around power equipment cannot be overemphasized.
Each piece of equipment has safety procedures unique to that particular piece of
equipment. Listed below are safety procedures that pertain to the Versa-Mil.
- Avoid dangerous environments. Do not use the Versa-Mil in damp or wet
locations. Do not expose the Versa-Mil to rain.
- Keep visitors away from running equipment. Keep visitors a safe distance
from the Versa-Mil while it is in operation.
- Store tools when not in use. Store or lock tools and equipment in the
- Do not force the equipment. The Versa-Mil will do the job better and
safer at the rate for which it was designed.
- Wear proper apparel. Keep shirt sleeves above the elbow. Remove ID tags,
watches, rings, and any other jewelry when working around the Versa-Mil.
- Use safety glasses. Wear safety glasses when operating any type of
machine shop equipment.
- Do not abuse the electrical cord. Never carry the Versa-Mil by the
electrical cord or pull on the cord to disconnect it from the receptacle.
Keep the cord away from excessive heat, oil, and sharp edges. Replace end
connectors or cords when excessive wear or damage is apparent.
- Maintain tools with care. Keep tools and cutters sharp and clean for the
best performance. Follow instructions in the Versa-Mil Operation and Service
Manual for lubricating the basic unit and changing accessories.
- Disconnect equipment not in use. Ensure the Versa-Mil is disconnected
when not in use, before servicing, and when changing attachments, speeds,
cutters, or arbors.
- Remove chuck keys and wrenches. Form a habit of checking to see that
chuck keys and wrenches are removed from the unit prior to operating the
equipment. Remove all tools from the area that may vibrate off the equipment
and into moving parts.
- Avoid accidental starting. Place protective cover around the switch to
help prevent accidental starting of the Versa-Mil. Ensure switch is off
before connecting the unit to a power supply.
- Outdoor use of extension cords. When using the Versa-Mil outdoors, use
only extension cords designed and marked for outdoor use.
- Reversing switch. Ensure that the reversing switch is in the correct
position for proper cutter rotation. Failure to do this could result in
damage or injury by having a cutter or arbor dislodged from the basic unit.
- Pulley guard. The pulley guard must be in place before operating the
Versa-Mil. This prevents fingers or clothing from getting caught between the
belt and pulleys.
- Handle cutters with care. Handle all cutters with a cloth to prevent
accidental cutting of fingers or hands.
- Grinding wheels. Use grinding wheels with the safe speed at least as
high as the no-load RPM rating of the Versa-Mil grinding attachment.
