10.11 CHOICE OF TOOL
The following requirements must be respected when choosing a tool:
1. Only use perfectly sharp tools. Make sure that they are locked firmly in the toolholder.
2. Never use bent, damaged, incomplete, or imperfectly balanced tools.
3. Always make sure that the surfaces of the tool are clean and undamaged before fitting it in the
collet.
Never operate tools beyond the rated speed punched on them or that
specified by the manufacturer.
10.12 WHAT TO DO IF THE TOOL IS BLOCKED ON THE PIECE BEING WORKED
In the models with an ISO type tool hooking, if the machine goes into emergency
mode or stops with the tool blocked on the piece being worked, do not move the
spindle along the Z axis!

If possible, release the piece manually and then carry out the tool changing manually.
If this is not possible, proceed in the following way:
1. Supply air to the tool changing circuit
2. Slowly move the spindle away from the piece, moving it along the Z axis until the collet
opens (“ON” output of sensor S2)
3. Check the collet spindle has been freed from the collet
4. Move the spindle completely away from the piece being worked
5. Remove the blocked tool manually.
If these procedures are not observed, the tool holder will drag the locking system (collet/tie-rod)
with it until the collet spindle is freed; owing to the force of the spring, the collet will then shoot back
violently, perhaps breaking the tie-rod.
