Warning:
To
avoid serious injury and ensure best results for your tapping operation, please read carefully
all
operator and safety instructions provided for this tapping unit as well as all other safety instructions that are ap-
plicable, especially those for your machine.
7.
Be aware of any other applicable safety instructions/requirements especially those for your machine.
8.
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 or handling.
Check List For Good Tapping
1.
Never
use this tapping attachment before reading all safety instructions for it as well as the machine it is to be
used on.
2.
Be sure tap is sharp and of correct design for your application.
3.
Be sure tap is in proper alignment with the drilled hole.
4.
Be sure the machine speed is correct.
5.
Be sure you are following the correct feed rate for the tap based on the pitch of the tap and revolutions per
minute.
6.
Make sure the drilled hole is the correct size.
7.
Be sure the machine stop is set correctly to avoid hitting the bottom of a blind hole. See Controlled Depth Tap-
ping.
8.
Be sure to allow for sufficient chip clearance especially when tapping blind holes.
9.
Make sure the work piece is clamped rigidly so that it is not able to move, rotate, or lift.
10.
Make sure there is enough clearance between the tap and work piece at the starting position and the retract
position to be sure the tap is clear of the hole upon retraction. Remember the tapping attachment spindle ex-
tends during reversal out of the hole.
11.
Make sure to mount a strong torque bar from the table of the machine, or to the non
-
rotating quill, to prevent
the stop arm from rotating. The torque bar must be stronger than the largest tap in the tapping attachments
capacity. It must also have a smooth surface so that the stop arm slides freely when feeding in and out of the
hole.
12.
Make sure to use the proper cutting fluid/lubricant for the application.
