USING THE NOVA DOWNFEED ATTACHMENT
Figure 1

Down feed attachment on the headstock
The Nova down feed attachment can be used in 2 different ways; precise control of the quill and quick movement of the quill.
The modes can be selected by turning the feed adjustment knob. Precision control mode is engaged by turning the feed adjustment
knob in the clockwise direction until it locks in firmly. To use the handles normally, the feed adjustment knob must be loosened.
Precision Quill Control
The precision control allows the user to have precise control over the quill extension by moving the quill for a very small amount.
This precision control function is ideal for NOVA Vulcan drill press which is capable of handling milling task. When the precision
control mode is engaged, the quill will automatically be locked in place at any position until the user turns the hand wheel to raise or
lower the quill.
When the precision control mode is engaged, the quill is extended by rotating the handwheel in the clockwise direction.
Quill
feed 2.5mm (1/10”) control per revolution on hand wheel. (When gears fully engaged)
Quill feed 0.025mm (1/1000”) control per division on the hand wheel. (When gears fully engaged)
Normal Quill Control
The down feed attachment also allows the user to keep on using their Voyager/ Vulcan drill press as normal drill presses by
disengaging the precision quill control.
Note:
If the down feed attachment binds at any point during its use, do not force the handle as it will potentially cause damage to the gear
teeth. If the down feed attachment binds, try turning the handwheel/ handle in the opposite direction or gently wiggle it. It is
advised to disassemble and clean out any external debris or fragments once it binds during use.
