High torque for powerful cutting of large-diameter workpieces
SLANT TURN 500, 550, 600 series
Achieves high-efficiency machining with full power even in low speed ranges.
The two-step gear shifting method can achieve high spindle speed and large cutting torque in two ranges.
| Max. torque | 7000 N・m |
| Main spindle power | 45 kW (60 HP) |
SLANT TURN 800
Achieves powerful machining of large-diameter workpieces.
The powerful spindle motor and the 4 step hydraulic gear shift inside the headstock provide a wide revolution speed range and high cutting torque.
| Max. torque | 12174 N・m |
| Spindle output | 60 kW (80 HP) |
Further improve productivity with a wide variety of options
High power milling spindle that rival those of small machining centers
SLANT TURN 500M, 550M, and 600M are capable of highly efficient milling / turning. A high-torque version is also optionally available.
VDI-type Turret (Milling setup)
Bolt-on turret (Standard setup)
Automatic steady rest with significantly reduced travel time (Optional)
A self-run type steady rest is available as an option. The tailstock can approach much closer to the steady rest for an expanded machining area.
* SLANT TURN 500, 550, and 600 series are only compatible with 2000U / 3000U / 4000U.
Highly rigidity tailstock
SLANT TURN 500, 550, 600 series
The tailstock quill can extend 250 mm making it possible to support both long and short shaft workpieces.
This eliminates the need to remove the steady rest when changing the workpiece from long to short shaft.
SLANT TURN 800
With a high hydraulic pressure thrust of up to 35 kN, it provides strong support for the workpiece.
