Overview
The Toshiba BMC-800 is a precision horizontal machining center produced by Toshiba Machine (now Shibaura Machine) — a Japanese machine tool builder with a long heritage in precision machining equipment for the automotive, aerospace, and precision engineering industries. The BMC-800 designation indicates an 800 mm pallet size horizontal machining center, placing it in the large-pallet HMC class alongside machines from Makino, Okuma, and Mazak targeting medium-to-large workpiece production applications.
The BMC-800 features an 800 mm x 800 mm (31.5 in x 31.5 in) pallet with a maximum workpiece envelope of 1,000 mm (39.4 in) diameter by 900 mm (35.4 in) height. The main spindle achieves 6,000 RPM at 37 kW (49.6 HP) through an ISO 50 taper interface, providing the low-speed torque characteristic of ISO 50 tooling for heavy milling cuts in steel, cast iron, and Inconel on large workpieces. Axis travels are 1,000 mm in X, 900 mm in Y, and 900 mm in Z, with rapid traverse of 40 m/min (1,575 IPM) on all linear axes. The CNC B-axis rotary table provides 4-axis simultaneous interpolation with 0.001-degree minimum increment and 15 RPM maximum rotation speed.
Toshiba equips the BMC-800 with the FANUC 16i or 30i-B control (depending on production year and configuration) and a 60-tool ATC. Positioning accuracy is ±0.005 mm (±0.0002 in) with ±0.003 mm (±0.00012 in) repeatability, achieved through Toshiba's thermal compensation algorithms and high-precision linear scale feedback. The machine is supported by a 2-station APC as standard, with multi-pallet pool configurations available. The BMC-800's cast-iron bed and column construction provides the thermal stability and static stiffness required for precision machining of aerospace and precision engineering components over long production runs.
Used and reconditioned Toshiba BMC-800 machines are typically found in the $150,000 to $400,000 range; new comparable Shibaura Machine HMCs are priced from $800,000 to $1,400,000.

Strengths & Limitations
Strengths
- ISO 50 spindle taper provides maximum rigidity and torque for heavy milling passes in steel, cast iron, and Inconel on large 2,500 kg workpieces that HSK-A100 tooling cannot match at low RPM
- 800 mm pallet with 1,000 mm maximum workpiece diameter accommodates a wide range of large automotive, aerospace, and heavy engineering components in a single setup
- Toshiba's reputation for precision and thermal stability means BMC-800 machines maintain ±0.005 mm accuracy over long production cycles without frequent re-calibration
- Used BMC-800 machines are available in the $150K-$400K range, providing large-pallet HMC capability at a significantly lower capital cost than a new comparable machine
Limitations
- Maximum 6,000 RPM spindle speed with ISO 50 taper is not optimized for high-speed machining of aluminum; shops with significant aluminum workloads should consider HSK-A63 HMCs
- Toshiba Machine rebranded to Shibaura Machine in 2020 — service and parts for the legacy BMC-800 brand must be sourced carefully to ensure genuine vs. aftermarket components
- 60-tool ATC may be insufficient for complex multi-operation programs on large aerospace or precision engineering workpieces with many different tool types

Frequently Asked Questions
01
Yes. Toshiba Machine Co., Ltd. changed its corporate name to Shibaura Machine Co., Ltd. in April 2020 to establish an independent brand identity following a reduction in Toshiba Corporation's shareholding. The machines are the same design continuity — Shibaura Machine continues to produce HMCs, injection molding machines, and other industrial equipment from the same facilities. Machines produced before 2020 carry the Toshiba Machine name and badge; new machines carry the Shibaura Machine identity.
02
ISO 50 (also known as CAT 50 or BT 50) tooling provides a larger taper engagement surface and a longer taper contact than HSK-A100, which translates to higher pull-out resistance and better rigidity for heavy roughing cuts at low spindle speeds. At 6,000 RPM maximum, the BMC-800 is optimized for heavy-torque applications where ISO 50's superior low-speed rigidity is beneficial. HSK-A100 tooling is better suited to higher-speed machining applications (above 8,000-10,000 RPM) where its self-centering taper face contact provides advantages.
03
Spare parts for the Toshiba BMC-800 are available through Shibaura Machine's authorized service network, which covers North America, Europe, and Asia. However, older machines (20+ years) may require longer lead times for certain wear components. Third-party machine tool rebuild companies also supply common wear parts (way wipers, seals, bearings) and servo components. Fanuc control parts (for machines with Fanuc 16i or 30i) are widely available through Fanuc's global service network.
04
Multi-pallet pool configurations were available from Toshiba Machine for the BMC-800, typically in 4, 6, 8, and 12 pallet configurations. On the used market, BMC-800 machines with factory multi-pallet systems are available but less common than the standard 2-station APC configuration. Retrofitting a used BMC-800 with a third-party pallet pool system is possible but requires careful engineering review for compatibility.
05
The BMC-800 was produced over multiple generations and was equipped with Fanuc 16i (older machines) or Fanuc 30i-B (later production) controls. Both provide full 4-axis simultaneous interpolation (X, Y, Z, B) and support standard EIA/ISO G-code programming. Fanuc 30i-B machines offer more advanced features including high-speed look-ahead, AICC (Artificial Intelligent Contour Control), and better thermal compensation algorithms. When purchasing used, buyers should confirm the specific Fanuc control version to ensure compatibility with existing shop programs and CAM postprocessors.
