Overview
The Nakamura-Tome AS-200 is a single-turret multitasking turning center combining turning, milling, drilling, and tapping in a compact footprint. The AS designation signals a more feature-rich platform than the SC series, with standard Y-axis milling capability and C-axis contouring.
The machine accommodates 6-inch or 8-inch chucks with a maximum turning diameter of 290 mm (11.4 in) using the standard 12-station turret, or 280 mm with the optional 15-station turret. Maximum turning length is 300 mm (11.8 in) with a distance between centers of 427 mm. Bar capacity is 65 mm or 71 mm. The main spindle delivers 15/11 kW (20/15 hp) at speeds up to 4,500 RPM.
The turret is a dodecagonal drum type supporting up to 24 tool stations (12 turning + 12 milling), or an optional 15-station turret. Milling capability includes 5.5/3.7 kW driven tools at up to 6,000 RPM. Standard Y-axis stroke is 82 mm for off-center milling. C-axis provides 600 RPM for polar interpolation.
Rapid traverse rates are 24 m/min on X and 36 m/min on Z. Machine dimensions are 1,852 x 1,655 x 1,665 mm. FANUC 0i-TF Plus controller features a 15-inch touchscreen with 2 MB storage.
Nakamura-Tome builds the AS-200 with thermal symmetry design and hand-scraped assembly methods, maintaining tight tolerances through multi-shift production.

Strengths & Limitations
Strengths
- Standard Y-axis and C-axis provide genuine milling capability for complex parts in a single setup
- Dodecagonal drum turret with up to 24 stations accommodates extensive tooling
- Compact 1,852 x 1,655 x 1,665 mm footprint enables cell clustering
- Nakamura-Tome thermal symmetry design maintains tolerances through multi-shift runs
- 6,000 RPM milling spindle at 5.5 kW delivers real milling capability
- FANUC 0i-TF Plus with 15-inch touchscreen supports modern workflows
Limitations
- 4,500 RPM main spindle speed is moderate for small aluminum or medical parts
- 290 mm max turning diameter constrains the machine to small-to-medium parts
- Single turret limits simultaneous cutting vs twin-turret machines
- North American dealer network through Methods is smaller than Mazak or Okuma

Frequently Asked Questions
01
The AS-200 has standard Y-axis milling, more turret stations (up to 24 vs 12), larger bar capacity (65/71 mm vs 51 mm), and higher spindle power (15 kW vs 11 kW). The SC-200 is simpler and less expensive.
02
Yes. The 65/71 mm bar capacity supports magazine bar feeders. Combined with a parts catcher, the AS-200 runs unattended for extended periods.
03
The optional 15-station turret provides 15 dedicated positions all capable of driven tooling vs the 12-station drum with shared positions.
04
New machines price between $150,000 and $220,000 depending on turret, sub-spindle, bar feeder, and coolant options.
