§ 10 OPERATION<br />
10.1 GENERAL PRECAUTIONS<br />
<strong>HSD</strong> S.p.A. has inspected and checked its electrospindles under the standard ambient conditions<br />
(CEI EN 60034-1:2006-05).<br />
Contact <strong>HSD</strong> S.p.A. for information on the possibility of applications in special ambient conditions.<br />
When machining, never allow non-cutting rotating parts (spindle shaft, toolholder etc.) to come into<br />
contact with the piece being machined.<br />
Accidental contact of this sort leads to a risk of serious damage to the electrospindle and injury to<br />
the operator.<br />
10.2 RUNNING IN<br />
The electrospindle is supplied already run-in and ready for installation. The factory running-in cycle<br />
includes careful testing of all controls and signals in simulated work cycles.<br />
10.3 WARMING UP<br />
When you power up the machine at the beginning of each day, allow the electrospindle to warm up<br />
slowly, to allow the bearings to reach a uniform operating temperature with consequent uniform<br />
expansion of the raceways.<br />
To warm up, run the spindle at the following speeds for the times specified:<br />
50% of max rated speed for 2 min.<br />
75% of max rated speed for 2 min.<br />
100% of max rated speed for 1 min.<br />
Repeat this cycle every time the machine is switched off for any length of time, to bring the<br />
electrospindle back up to operating temperature gradually and uniformly.<br />
While the machine operating, the spindle can reach high temperatures.<br />
Be very careful not to touch it without due precautions.<br />
i Preheating is carried out without tool holder.<br />
10.4 TOOL LOCKING AND RELEASE<br />
The tool is mechanically locked by springs.<br />
The tool is released by means of a single acting piston actuated by compressed air at 6 bar.<br />

To prevent the toolholder from sticking, remove it after machining.<br />
Always protect the internal parts of the spindle:<br />
lock in a clean and ambient-temperature toolholder when the spindle is not<br />
machining.<br />
