Goodson 3D-FAST CUT Manual De Instrucciones

Please read instructions before using
Instructions
1. Select a pilot, tapered or straight
Make sure that the cylinder head is clamped securely so
that the cylinder head/machine cradle combination is as
rigid as can get on your system. The 3-D Fast Cut™ ball
head works with both tapered and straight pilots and lets
you turn "dead" pilots into "live" pilots if desired. If you
use a "dead" pilot, select a pilot that fits the guide. If you
use a "live" pilot, make sure that you select a pilot with as
little clearance as possible within the guide. Remember
that a "live" pilot must revolve within the guide. Lock the
pilot within the ball head tightening the screws on the side
of the ball head. For better performance, use a carbide
pilot. Carbide pilots provide greater stability than tool
steel, resisting 5 times the deflection force. (For more
information on carbide pilots please call Goodson, 1-800-
533-8010.)
2. Select appropriate tip holder
Do so according to the ID of the seat you intend to cut.
3. Select the desired tip profile and install the tip on the
tip holder.
4. Slide the tool setting device onto the valve stem.
Position the pointer to the desired seat location on the
face of the valve where you want the top of the seat area
to contact the valve. Remove the tool setting fixture and
transfer onto the pilot already in place within the ball head.
Slide the tip holder onto the ball head in-and/or-out by
adjusting the side adjustment screw until the tool setting
device pointer contacts the desired seat area on the
carbide tip profile. Lock the two tip holder screws located
at the bottom of the ball head.
5. Select the spindle rotation speed.
Lower RPM will produce better results with most systems.
6. Select appropriate bounce spring and bushings.
Install on pilot.
Check that the spring selected provides sufficient
pressure to press the ball head into the drive properly.
7. Align ball drive with drive adaptor as accurately as
possible.
8. Using a pilot long enough to go through the entire
guide is a must to achieve good concentricity.
9. Refrain from tapping the carbide tip against the valve
seat while aligning the ball head with the pilot.
New carbide tips may chip if tapped against the valve seat
while the Tool Assembly is not turning.

Troubleshooting
• Check that the cylinder head is clamped properly onto the
machine so that it cannot vibrate. Eliminate all vibrations
that you possibly can. Whole system must be as rigid as
possible.
• Level the cylinder head and check that the axis of the
spindle of your machine/ system is perfectly parallel to the
axis of the pilot and that the pilot is as perpendicular as
possible to the table of the machine.
• Check that the spring and bushings selected provide
enough pressure to press the ball head within the drive
adaptor.
• Lubricant may help cutting and may also help prevent
build-up on carbide tip.
• Be sure to select proper cutting speed. "Proper speed"
will vary from one
set-up to another.
Very slow speeds
recommended.
• Tips not sharpened
properly or over-
sharpened may
cause cutting
problems such as
chatter.
NOTE: Starter Kits
do not include a drive
adaptor. Please order
separately.
