Overview

The Toshiba BTD-200QH (now sold under the Shibaura Machine brand following the 2020 name change from Toshiba Machine) is a table-type horizontal boring and milling machine built for precision machining of large castings, weldments, and structural components. With a #50 taper spindle running at 3,000 RPM, 30 kW (40 hp) of spindle power, and axis travels of 1,500 mm (X) x 1,200 mm (Y) x 700 mm (Z) plus a 400 mm W-axis quill extension, the BTD-200QH sits in the sweet spot for shops machining medium-to-large workpieces that demand the rigidity and accuracy of a horizontal boring mill.

The 1,000 x 1,200 mm (39.4 x 47.2 in) rotary table carries loads up to 4,000 kg (8,800 lb) and indexes in 1-degree increments for four-sided machining without reclamping. The 109 mm (4.3 in) spindle diameter provides the rigidity needed for boring operations in cast iron and steel, while the W-axis quill extends 400 mm (15.7 in) for reaching into deep bores and cavities. The 30-tool automatic tool changer handles tools up to 125 mm (4.9 in) diameter (or 239 mm / 9.4 in with adjacent pockets empty) and 400 mm (15.7 in) in length, with a maximum tool weight of 25 kg (55 lb).

Rapid traverse rates of 12 m/min on X, Y, and Z axes (and 5 m/min on the W-axis) are typical for a machine of this class, where precision matters more than speed. The cutting feed rate reaches 6 m/min (236 ipm). At 18,000 kg (39,600 lb), the BTD-200QH has serious mass for vibration damping during heavy boring cuts. The machine runs on the TOSNUC 999 CNC control, which Shibaura Machine has developed over decades specifically for their horizontal boring mills.

The BTD-200QH competes with the Kuraki KBT-15DX, Doosan DBC-130, and Okuma MB-5000H in the mid-size horizontal boring mill market. Toshiba/Shibaura's advantage is their deep experience in horizontal boring — they've been building these machines since the 1960s — combined with Japanese manufacturing quality. Through-spindle coolant is available as an option, and a high-speed 5,000 RPM spindle variant exists for shops that need faster speeds on aluminum or lighter cuts. For moldmakers, die shops, and general machining operations handling large castings and weldments, the BTD-200QH delivers the boring accuracy and surface finish quality that this class of machine is known for.

Strengths & Limitations

Strengths

109 mm spindle diameter provides exceptional boring rigidity for precision hole work in large castings and weldments
4,000 kg table load capacity handles heavy castings, mold bases, and structural weldments without concern
400 mm W-axis quill extension reaches into deep bores and cavities that standard VMCs and HMCs cannot access
18,000 kg machine weight delivers excellent vibration damping for heavy boring cuts and fine surface finishes
30-tool ATC with 25 kg tool weight capacity accommodates large boring bars and face mills
Japanese manufacturing quality with 60+ years of horizontal boring mill experience from Toshiba/Shibaura Machine

Limitations

3,000 RPM standard spindle speed is limiting for aluminum work and smaller tools — the 5,000 RPM option adds cost
12 m/min rapid traverse is slow by modern VMC/HMC standards, though typical for this machine class
TOSNUC 999 control has a smaller user community than Fanuc or Siemens, which can complicate finding experienced operators
Shibaura Machine's North American service network is smaller than Mazak's or Okuma's, with longer response times in some regions
18,000 kg weight requires substantial floor preparation and rigging for installation

Best For

Mold and die shops machining large mold bases, die sets, and tooling plates requiring precision boring and facing Heavy equipment manufacturers machining large cast iron housings, gear boxes, and frame components General machining job shops handling large weldments and fabrications requiring four-sided machining on the rotary table Power generation equipment shops boring turbine casings, valve bodies, and pump housings Shops needing deep-bore machining capability with the W-axis quill for features beyond standard Z-axis reach

Frequently Asked Questions

01 What is the difference between the BTD-200QH and the BTD-200QHV?

The BTD-200QHV adds a vertical milling head option (V = Vertical), allowing the machine to perform vertical milling operations in addition to horizontal boring and milling. This adds versatility for face milling, pocket milling, and drilling operations that benefit from a vertical spindle orientation. The base BTD-200QH is horizontal-only.

02 Why choose a horizontal boring mill over a large VMC?

Horizontal boring mills excel at precision bore work in large castings — the horizontal spindle orientation allows chips to fall away from the bore, the W-axis quill reaches deep cavities, and the rotary table enables four-sided machining. Large VMCs are faster for face milling and drilling but cannot match the boring accuracy and deep-reach capability of a dedicated HBM.

03 Is Toshiba Machine the same as Shibaura Machine?

Yes. Toshiba Machine was renamed Shibaura Machine in April 2020. The machines, engineering team, and manufacturing facility are identical — only the brand name changed. Many shops and dealers still refer to these machines as 'Toshiba' informally. Spare parts and service are fully supported under the Shibaura Machine name.

04 What accuracy can the BTD-200QH achieve?

Positioning accuracy is typically ±0.005 mm and repeatability ±0.003 mm on all linear axes. Boring roundness of 0.005 mm or better is achievable on the W-axis quill. The rotary table indexes to within ±2 arc-seconds. These figures are verified during acceptance testing and are maintainable with proper thermal management and regular maintenance.

05 What foundation is required?

At 18,000 kg, the BTD-200QH requires a reinforced concrete foundation typically 300-500 mm thick, depending on soil conditions. Shibaura Machine provides foundation drawings during the pre-installation phase. Foundation leveling bolts and anti-vibration mounts are standard. Plan for $15,000-$30,000 in foundation preparation costs.
