Overview

Kitamura describes the Bridgecenter-12G as a double column machining center. Its X axis travels 3050 mm (120.1 in) over a table 3500 mm (137.8 in) long and 1370 mm (53.9 in) wide, with 1615 mm (63.6 in) of Y and 800 mm (31.5 in) of Z.

Length is the only thing that separates it from the model below. The Bridgecenter-10G has 2540 mm (100 in) of X and a 1370 × 3000 mm (53.9 × 118.1 in) table, and shares the Y and Z travels, the spindle, the magazine and the 24 m/min (945 ipm) rapid rate. So the choice between the two comes down to the longest part, or the longest row of fixtures, you expect to run. One step further down, the Bridgecenter-8G has 2032 mm (80 in) of X on a 900 × 2500 mm (35.4 × 98.4 in) table and is also listed with a No. 40 spindle reaching 20,000 rpm, a combination the 12G's table does not include.

The table is rated for 6,000 kg (13,227 lb). Because X travel is shorter than the table, 3050 mm against 3500 mm, the last stretch at each end is there for clamps, overhang and fixture plates and cannot be cut in the same setup. Y is the opposite case: 1615 mm of travel across a 1370 mm table lets the spindle run off both edges, which helps when facing the full width or probing an outside datum.

The spindle is an NST No. 50 unit (HSK-A100 optional) with four-step gear drive and a range of 35 - 12,000 rpm, and the magazine carries 40 tools, or 60 or 80 tools as options. No power or torque row is published in the table. Positioning accuracy is ±0.002 mm (±0.000079 in) over the full stroke with ±0.001 mm (±0.000039 in) repeatability, and those numbers have to be held over more than three metres of X. Plan for a 50 kVA supply at 200 V AC, three-phase.

Strengths & Limitations

Strengths

3050 mm (120.1 in) of X travel on a 1370 × 3500 mm (53.9 × 137.8 in) table
1615 mm (63.6 in) of Y travel is greater than the 1370 mm (53.9 in) table width, so the spindle reaches past both table edges
Table rated for 6,000 kg (13,227 lb) of workpiece and fixturing
±0.002 mm (±0.000079 in) full-stroke positioning accuracy and ±0.001 mm (±0.000039 in) repeatability on a machine of this length
NST No. 50 geared spindle with a 35 rpm low end for large cutters and a 12,000 rpm top speed

Limitations

The 3500 mm (137.8 in) table is longer than the 3050 mm (120.1 in) X travel, so a part that fills the table needs a second setup to finish its ends
Only a No. 50 spindle topping out at 12,000 rpm is listed; the 20,000 rpm No. 40 spindle of the Bridgecenter-8G is not in this table
Rapids of 24 m/min (945 ipm) mean a full traverse of X takes several seconds, which adds up on parts with features at both ends
Spindle power and torque are not stated, and the larger magazines and the HSK-A100 taper are options

Best For

Long weldments, rails and plates up to 3050 mm (120.1 in) in X Heavy single parts up to 6,000 kg (13,227 lb) Rows of fixtures along a 3500 mm (137.8 in) table Low-speed 50-taper boring and face milling

Frequently Asked Questions

01 When does the Bridgecenter-12G make sense over the Bridgecenter-10G?

When the work needs more than the 2540 mm (100 in) of X travel the Bridgecenter-10G provides. The Bridgecenter-12G raises that to 3050 mm (120.1 in), and its table is 3500 mm long where the Bridgecenter-10G table is 3000 mm, both 1370 mm wide. Nothing else in the two tables differs: Y, Z, spindle, tool capacity, table load, rapid rate and accuracy are identical.

02 How much weight can the Bridgecenter-12G table carry?

6,000 kg (13,227 lb). The table itself measures 1370 × 3500 mm (53.9 × 137.8 in), so the rating covers long, heavy parts, but remember that fixtures, risers and clamps count toward the same limit.

03 What speeds and tapers are available on the Bridgecenter-12G spindle?

The listed spindle runs 35 - 12,000 rpm through a four-step gear drive. NST No. 50 is the standard taper and HSK-A100 is the optional one. Kitamura's table gives no power or torque figure for it, so ask for the spindle output diagram when you request a quote.

04 What accuracy does Kitamura list for the Bridgecenter-12G?

Positioning accuracy of ±0.002 mm (±0.000079 in) over the full stroke and repeatability of ±0.001 mm (±0.000039 in). On this model the full stroke in X is 3050 mm (120.1 in), so foundation and temperature control at the installation site matter if you expect to see those figures on the part.

05 How many tools does it hold and what supply does it need?

40 tools as standard, with 60 or 80 tools available as options. The electrical requirement is 50 kVA at 200 V AC, three-phase. Rapid traverse is 24 m/min (945 ipm).
