Mounting a Faceplate or Chuck
1. Use the Spindle Index Pin to lock the
headstock spindle.
2. Remove the side-locking screw, then wind the
faceplate or chuck onto the spindle threads. A
spindle washer in between may be used to
make removal easier.
Warning!
The faceplate or chuck body must contact
the shoulder on the spindle bearing.
3. Pull and turn the Index Pin and place it in the
"safe" indentation in the headstock.
4. A vee groove is provided in the spindle for a
special locking grub screw that is used in
conjunction with Nova chucks and accessories
to prevent unwinding during reverse
operations. Wind in the side-locking grub
screw and lock firmly in place, without over
tightening.
Warning!
It is important that all Chucks and
Faceplates that are used on the DVR
SATURN spindles have a side-locking
function.
Some older Teknatool products may not
have a side-locking function. If any of these
products are intended to be used on the
DVR SATURN spindle they will need to
undergo a modification to include the side-
locking function or new products purchased
with a side-locking function. All spindle
mounted products produced by Teknatool
International for the DVR Lathe have side-
locking functions*.
The side-locking function should be used at
all times while running the chuck on the
spindle during operation. Without this
function engaged the Chuck or Faceplate
may unwind from the spindle during
operation.
Warning!
When installing or removing the Faceplate or Chuck from the
spindle, the side-locking grub screws MUST be completely
removed.
This avoids any potential damage to the spindle that the grub
screws may cause if it were not completely removed, when
winding the Faceplate or Chuck on or off the spindle.
*Exception 1. When an ILNS insert is used with a FP150Z
faceplate on the DVR3000 or a Spindle adaptor, the insert or
adaptor must be located onto the faceplate to avoid it
unwinding when the spindle is run in reverse. Loctite 272
Thread locker is recommended.
*Exception 2. Customers with dedicated threaded Teknatool
chucks who intend using the chuck on the DVR SATURN
Spindle must have a side-locking function adapted to the
chuck before running it. Chucks with M33 threads may apply
for Europe.
IMPORTANT NOTE
The Index Pin is designed for indexing and not for leveraging
against, when removing faceplates, inserts and chucks. For
this we recommend holding the spindle using the operating
bar through the 2 LHB holes (Left Hand Brake).
