A compact machine with one of the largest machining areas in its class
This machining center has a large machining area despite its efficient use of floor space
Floor space
2,300 × 5,065 mm (90.55 × 199.41 in) (11.6 m2 (124.86 ft2))
Machining area
X-axis travel:560 mm
Y-axis travel:650mm (longer than previous machine)
Z-axis travel:685mm (longer than previous machine)
Max workpiece size
ø630 × 900mm (ø24.8 × 35.43 in)(more than previous machine)
Note: Standard 2-pallet APC specications
Max tool length
450mm (longer than previous machine)
Agile machine operation
Reduced positioning time
- Rapid traverse X-Y-Z axes: 60 m/min (2,362 ipm)
- Rapid traverse acceleration (max)
X-Y axis:1.0G
Z-axis:1.1G*
Reduced table indexing time
- 90° indexing:0.8 seconds*
- 180° indexing:0.98 seconds*
* At low inertia
Heavy-duty cutting possible throughout entire machining area
The highly rigid B-axis bearings enable heavy-duty cutting of steel even on the upper Y-axis.
Maximized operation time through chip control
Offers both improved chip discharge functionality and eco-friendly operation
The angle of the internal cover has been increased, and it has been designed with a flat cover inside the machining chamber to greatly improve chip discharge.
A full center trough mechanism prevents chip accumulation by discharging chips from the entire machining area. Pinpoint cleaning of locations where chips tend to accumulate reduces the amount of coolant used and prevents the accumulation of chips while also being environmentally friendly. Easier chip discharge reduces the frequency of internal cleanings that are required, reducing the workload of operators.
“Sludgeless Tank” enhances stable operations (recommended option)
The number of troublesome coolant tank cleaning operations is signicantly reduced, improving productivity.
Furthermore, environmental impact due to coolant disposal is also reduced.
