The automatic tool changer includes:
- a tool magazine
- ISO30 tool holder tapers
- ER32 collets
- a 9 kW spindle with automatic tool change
- a controller card capable of managing automatic tool change
Operation:
When a tool change is necessary, the spindle automatically positions itself above the tool magazine to deposit the current tool holder and pick up a new one. The tool holder consists of an ISO30 taper at its upper part and a chuck (ER collet) that clamps the milling cutter at its shank. The taper is held to the spindle by a valve controlled by a pneumatic system. Once the tool holder is fixed, an automatic measurement of the new tool’s length is optional: the spindle positions itself above the automatic probe to descend in Z until it touches the tip of the milling cutter. Machining can then begin.
Automatic tool change requires a pneumatic supply to allow the tapers to be held on the spindle. A compressor is necessary and requires the following minimum capacities (power: 5.5 kW (7.5 HP); volume: 1000 L; pressure: 0.8 MPa (8 bar); flow rate: 0.7 m³/min).
