The pressurisation air must be present even when the electrospindle is at a
standstill and the machine is switched on. It must be present also when cleaning
or servicing the machinery, to prevent dust from other machining areas entering
the spindle.
Check with the spindle at standstill that there is a uniform outlet of air around the spindle shaft
(pressurisation); if this is not the case, check the efficiency of the pneumatic circuit and the
tightness of the connections.
