Operating manual for pneumatic grinding spindle

Connection and commissioning
Connection to compressed air supply line
The compressed air used to power the BIAX pneumatic
grinding spindle must be clean and free of water! To
ensure this, connect the machine to a maintenance unit
with water trap! The maintenance unit should be installed
as close as possible to the grinding spindle.
•
Prior to connecting the hose, blow through it to
remove any dirt!
•
Connect the pneumatic grinding spindle (A) to the
maintenance unit (D1 - D2), using the hose kit (B)
and the threaded nipple (C) (see Fig. 1).
•
Mount maintenance unit (D1 - D3) in the following
sequence: water trap (D1) - pressure controller (D2)
- aerosol lubricator (D3).
•
At the maintenance unit, set the operating pressure
to max. 6 bar. Check oil level and add oil, if
necessary.
•
Set the maintenance unit to an air lubrication rate of
2 to 3 drops of oil per minute.

The air supply to the grinding spindle
must be controlled by means of an
external device, as the grinder does not
include a respective valve/switch.
When the compressed air line is
connected, the spindle begins to rotate
immediately. Therefore close the control
valve before connecting the compressed
air line.
