Overview
The Kitamura SuperCell 400 is a compact, high-precision horizontal machining center designed for unattended production of small to medium prismatic parts. Kitamura, a Japanese manufacturer with a reputation for building machines that hold extreme accuracy over extended runs, positioned the SuperCell 400 as a cell-ready HMC that can operate lights-out with minimal operator intervention. With 400 mm (15.7 in) pallets and a focus on thermal stability, the SuperCell 400 targets job shops and production facilities where accuracy consistency matters more than raw material removal rate.
The SuperCell 400 features axis travels of 560 mm (22 in) in X, 510 mm (20.1 in) in Y, and 510 mm (20.1 in) in Z. The spindle runs at up to 15,000 RPM with 18.5 kW (25 HP) continuous power through a BT40 interface (Cat 40 in North America), with optional high-speed spindle configurations available up to 20,000 RPM. Rapid traverse rates are 48 m/min (1,890 IPM) on all linear axes. The B-axis rotary table provides 1-degree indexing as standard with 0.001-degree indexing available.
Kitamura's claim to fame is their hand-scraping process. Every SuperCell 400 has its critical mating surfaces hand-scraped to ensure geometric accuracy that exceeds what CNC manufacturing alone can achieve. This labor-intensive process, combined with temperature-controlled spindle cartridges and thermal displacement compensation, allows the machine to maintain positional accuracy of ±0.002 mm (±0.00008 in) and repeatability of ±0.001 mm (±0.00004 in) even during extended production runs.
The machine runs on Fanuc 31i-B5 control and includes a standard 40-tool magazine with options for 60, 90, or 120 tools. The 2-pallet APC (Automatic Pallet Changer) is standard, and multi-pallet pool systems are available for true lights-out operation. New SuperCell 400 machines typically price in the $300,000-$450,000 range. Used units from 2015-2022 appear in the $150,000-$280,000 range.

Strengths & Limitations
Strengths
- Hand-scraped mating surfaces deliver geometric accuracy that machine-finished surfaces cannot match, maintaining ±0.002 mm positioning over extended runs
- ±0.001 mm repeatability is among the best in the 400mm pallet class, making it suitable for the most demanding tolerance requirements
- Thermal compensation and temperature-controlled spindle maintain accuracy during multi-hour unattended production runs
- Compact footprint relative to its work envelope makes it practical for shops adding HMC capability without major floor space commitment
- Fanuc 31i-B5 control is a premium controller with advanced features including high-speed look-ahead and fine surface control
- Multi-pallet pool expansion options enable true lights-out manufacturing growth without replacing the base machine
Limitations
- BT40/Cat 40 spindle limits rigidity compared to HSK-A63 or BT50 machines when heavy roughing in hard materials is required
- 18.5 kW spindle power is adequate but not exceptional; shops needing aggressive material removal should consider larger platforms
- Kitamura's dealer and service network is smaller than Mazak, Okuma, or DMG Mori, which can mean longer service response times
- 400 mm pallet size limits maximum workpiece dimensions compared to 500mm-class competitors

Frequently Asked Questions
01
New Kitamura SuperCell 400 machines typically price between $300,000 and $450,000 depending on spindle speed option, tool magazine capacity, and pallet system configuration. Adding a multi-pallet pool system can push the total investment above $550,000. Used SuperCell 400 units from 2015-2022 sell in the $150,000-$280,000 range and remain excellent values due to Kitamura's long-term accuracy retention.
02
Hand-scraping is a manual process where a skilled craftsman uses a scraping tool to create precise mating surfaces on the machine's critical joints (bed-to-column, slide surfaces, etc.). This creates a pattern of high spots and oil retention pockets that provides better geometric accuracy and smoother motion than machine-ground surfaces alone. Kitamura is one of the few manufacturers that still hand-scrapes production machines, and it's a significant factor in their long-term accuracy retention.
03
Both are premium 400mm-class HMCs with strong accuracy reputations. The Makino a51nx offers higher spindle power (22 kW) and faster rapids (60 m/min), making it better for aggressive aluminum machining. The Kitamura SuperCell 400 counters with hand-scraped surfaces and slightly tighter repeatability specs. The Makino has a larger dealer network. Both are excellent machines; the choice depends on whether accuracy consistency or cutting performance is the higher priority.
04
Yes, the SuperCell 400 was designed for unattended operation. The 2-pallet APC is standard, and multi-pallet pool systems with 6-12 pallets enable extended lights-out runs. Combined with the 40-120 tool magazine, in-process probing, tool breakage detection, and Kitamura's thermal stability, the machine can run unattended for full overnight shifts. Many shops report 6-8 hours of reliable unattended operation routinely.
05
The SuperCell 400 offers several spindle configurations: a standard 15,000 RPM / 18.5 kW unit for general-purpose machining, a high-speed 20,000 RPM option for high-speed aluminum machining, and high-torque variants for harder materials. All use BT40/Cat 40 tooling. The choice depends on the primary material and operation type. Most shops opt for the 15,000 RPM spindle as the best all-around choice.
06
Kitamura machines are renowned for holding accuracy over decades of operation. Many shops report that 15-20 year old Kitamura machines still hold original accuracy specifications, which is attributed to the hand-scraped surfaces and quality of the cast iron construction. This longevity makes Kitamura machines excellent long-term investments, and used Kitamura machines command premium prices relative to other brands of similar age.
