The automatic tool changer includes:
- a tool magazine
- ISO30 tool-holder tapers
- ER32 collets
- a 9 kW spindle with automatic tool change
- a controller board capable of managing automatic tool change
Operation:
When a tool change is required, the spindle automatically positions itself above the tool magazine to place the current tool holder and pick up a new one. The tool holder consists of an ISO30 taper at the top and a chuck (ER collet) that clamps the cutter on its shank. The taper is held in the spindle by a latch controlled by a pneumatic system. Once the tool holder is secured, optional automatic measurement of the new tool length can be performed: the spindle positions itself above the automatic probe and moves down in Z until the tip of the cutter touches it. Machining can then begin.
Automatic tool change requires a pneumatic supply to hold the tapers in the spindle. A compressor is required with the following minimum specifications (power: 5.5 kW (7.5 hp); volume: 1,000 L; pressure: 0.8 MPa (8 bar); flow rate: 0.7 m³/min).
