components of unit batch size, and in due course the machine has the
following characteristic features [30].

1. Tool storage system, in which the tool is transferred through the
crate type pallet (tool crate) carried by the AGV (automatic guided
vehicle).
2. Vertically allocated twin spindle with water cooling, each of which is
mounted on the individual Z axis slide unit positioned one above the
other.
3. For light alloy machining, the speed of main spindle with tapered hole
of No. 30 ISO is 12,000 rpm maximum, for which the main motor has
15 kW in output.
4. The double-sided pallet loader supporting the pallet with the work
rotates through 90° anticlockwise to position the pallet vertically
and then transfers the pallet between the machining area and the
pallet loader.
