3.7.5 Spindle extension with ceramic bearings (OPTIONAL)
For ER 32 or ER 40, it extends the spindle to 170 mm.
Equipped with 2 pairs of angular-contact, ceramic bearings, 12.000 rpm max.
It guarantees the same characteristics as the standard spindle.
It is fixed with 4 screws directly on the original spindle.
3.7.6 Tool changer (OPTIONAL)
Upon request, the work center can be equipped with a numerically controlled tool changer
(additional interpolated axis) without any pneumatic movement, in order to ensure maximum
precision and reliability. The tool-holder movement occurs without any kind of backlash or
interference, thanks to an extremely accurate gearmotor (the same used for the rotating
movements of the machining head).
The maximum diameter of the tools which can be housed in the tool changer is 200 mm.
The tool changer may be equipped, depending on specific request, with “ISO 30” or “HSK63F” tool
fittings.
The tool-holder is provided with dust protection and can be 6 or 16 positions; it is mounted on an
independent structure located aboard the machine.
