 |
| To
avoid serious injury and ensure best result for your
tapping operation, Please Read Carefully All operator
and safety instructions provided for your tapping
attachment as well as all other safety instructions
that are applicable, especially those for your machine
tool. |
|
 1.
Proper Clothing: The
rotating spindle of a machine tool can snag loose
fitting clothing, jewelry or long hair. Never wear
jewelry, long sleeves, neckties, gloves or anything
else that could become caught when operating a machine
tool. Long hair must be restrained or netted to prevent
it from becoming entangled in rotating spindle. Steel
toed boots should also be worn in any machine environment. |
|
| 2.
Proper Eye Protection: Always
wear safety glasses with side shields to protect
your eyes from flying particles. |
 |
|
|
| 3.
Proper Work Piece Fixturing: Never hold
the work piece or the vise it is held in, by
hand. The work piece must be clamped firmly
to the table of the machine so that it cannot
move, rotate or lift. |

|
| Never extend
the length of the standard stop arm supplied
with your tapping attachment. A lengthened stop
arm could break free, hitting the operator and
causing serious injury. |
 |
|
|
| Never hold
the stop arm by hand. On reversal, full power
of the machine is transmitted through the stop
arm and the operator could be seriously injured. |
 |
|
|
| Always mount
a torque bar to hold the tapping attachment's stop
arm from rotating. The torque bar must be mounted
securely to the table or quill of your machine. The
torque bar installation must be stronger than
the largest tap in the capacity range of your tapping
attachment. |
|
| 7.
Continuous High Production Manual Tapping: Models
for use on conventional drill press or milling machines.
Speed is a critical factor in tapping. Please always
refer to recommended tapping speed chart. Tapmatic
Torque Control Reversing Tapping Attachments employ
a planetary gear reversing mechanism that increases
speed by a 1.75 x 1 ratio. This means that a machine
speed of 2,000 RPM results in a reversing speed of
3,500 RPM. It is strongly recommended that you consider
the AVERAGE TAPPING SPEED rather than machine
speed when calculating your cycle time. For example,
if machine speed is 1,500 RPM, reverse speed is 2,625
RPM, making your AVERAGE TAPPING SPEED 2,062 RPM.
You must not exceed the maximum allowable speed marked
on your tapping attachment. |
|
| 8. On
Machining Centers: The
same rule for installation applies whether using
the torque bar holder assembly with stop arm, torque
bar cup assembly or stop block assembly. "Always be
sure that the installation is stronger than the largest
tap being used." |
|
 |
|
| 9. Always
Be Aware Of The Potential Hazards Of A Machining
Operation: Sometimes
working with your machine can seem routine. You may
find that you are no longer concentrating on the
operation. A feeling of false security can lead to
serious injury. Always be alert to the dangers
of the machines with which you work. Always keep
hands. Body parts, clothing, jewelry and hair out
of the areas of operation, when the machine spindle
is rotating. Areas of operation include the immediate
point of machining and all transmission components
including the tapping attachment. Never bring your
hand, other body parts or anything attached to your
body into any of these areas until the machine spindle
is completely stopped. |
|
| 10. The
tapping attachment housing, drive spindle and tap itself
can become hot to the touch after operation. Use caution
when removing the attachment from the machine of handling. |
|
| 11. Be
aware of any other applicable safety instructions requirements. |
|
| Check
List For Good Tapping: |
|
|
|
- Never use the tapping
unit before reading all safety instructions
for it as well as those for the machine it
is to be used on.
- Is tap sharp and of correct
design for current job?
- Is tap in proper alignment
with drilled hole?
- Is machine speed correct?
- Is machine feed correct?
- Is machine stop set properly
so tap releases in neutral rather than bottoming
in work piece or fixture?
- Is work piece held rigidly
against rotation and upward movement?
- Is clearance between the drilled
hole and tap sufficient at start position to
allow the tap to clear the hole upon retraction?
- Is the stop arm of the tapping
attachment held rigidly against rotation by the
torque bar extending from the machine?
