Any drainage pipes must be orientated
downwards. The pipes must remain
downward-facing even when the machine
moves the electrospindle.
During normal use of the fluid distributor, the following precautions should always be
adopted when the electrospindle is not rotating.
• Introduction of pressurised air (4 ÷ 6 bar) before inserting the coolant.
• Every time the flow of coolant ends, use a jet of pressurised air to discharge the
circuit and thereby prevent any residual liquid from seeping out of the drainage
points unexpectedly.
For further information please refer to the documentation supplied by the rotating joint
manufacturer.
