Overview

The Kitamura Bridgecenter-6G #40 is a large vertical machining center with 1,530 mm (60.2 in) of X travel, 1,095 mm (43.1 in) of Y and a No. 40 taper spindle that runs from 20 to 20,000 rpm. Of the two Bridgecenter-6G builds it is the high-speed one, meant for big workpieces that are machined with small and medium tools.

The table measures 900 x 1,800 mm (35.4 x 70.9 in) and carries 3,000 kg (6,600 lb). Two relationships in those numbers are worth noticing. Y travel is greater than the table is wide, so the spindle covers the whole width and can run off the edge of a plate. X travel is shorter than the table is long, so the far ends of the table are clamping room, not cutting room. Z travel is 710 mm (28 in).

The spindle is four-step gear driven, on an NST No. 40 taper with HSK-A63 optional. Gearing lets it turn slowly with useful torque and still reach 20,000 rpm for finishing aluminium or cutting fine detail in plate and mould work. Power and torque are not in the table. Where the job is heavy steel removal, the Bridgecenter-6G #50 offers a No. 50 taper spindle at 35 to 12,000 rpm on the same travels and table.

Rapids are 24 m/min (945 ipm), which is modest. On a part with features spread along 1,530 mm of X, repositioning time is noticeable and cycle estimates should allow for it. Accuracy is listed as ±0.002 mm (±0.000079 in) over the full stroke with ±0.001 mm (±0.000039 in) repeatability. Magazine options of 60 and 80 tools are listed. Supply is 35 kVA at 200 V AC, three-phase. For longer work the Bridgecenter-8G #40 extends X to 2,032 mm (80 in) on a 900 x 2,500 mm (35.4 x 98.4 in) table.

Strengths & Limitations

Strengths

20 to 20,000 rpm four-step gear-driven No. 40 spindle on a machine with 1,530 mm (60.2 in) of X travel
900 x 1,800 mm (35.4 x 70.9 in) table rated for 3,000 kg (6,600 lb)
Y travel of 1,095 mm (43.1 in) exceeds the 900 mm table width, so the full width of a plate is within reach
Listed accuracy of ±0.002 mm (±0.000079 in) over the full stroke and ±0.001 mm (±0.000039 in) repeatability

Limitations

Rapid traverse is 24 m/min (945 ipm), slow across a 1,530 mm (60.2 in) axis
X travel of 1,530 mm (60.2 in) is shorter than the 1,800 mm table, so the table ends cannot be fully machined
No spindle power or torque figure is listed
HSK-A63 and the 60 and 80 tool magazines are options

Best For

Large aluminium plates and panels finished at up to 20,000 rpm Mould and die detail work with small cutters over a 900 x 1,800 mm table Several vises or fixtures set along 1,530 mm (60.2 in) of X travel Workpieces up to 3,000 kg (6,600 lb)

Frequently Asked Questions

01 What is the difference between the Bridgecenter-6G #40 and the #50?

The spindle. The Bridgecenter-6G #40 has an NST No. 40 taper spindle that runs from 20 to 20,000 rpm, with HSK-A63 optional. The Bridgecenter-6G #50 has an NST No. 50 taper spindle at 35 to 12,000 rpm, with HSK-A100 optional. Travels and the 900 x 1,800 mm (35.4 x 70.9 in) table are the same.

02 How big is the table and how much can it carry?

The table is 900 x 1,800 mm (35.4 x 70.9 in) with a load capacity of 3,000 kg (6,600 lb). Travels are 1,530 mm (60.2 in) in X, 1,095 mm (43.1 in) in Y and 710 mm (28 in) in Z, so Y covers the full table width while X stops short of the table length.

03 Is a gear-driven 20,000 rpm spindle good for steel as well as aluminium?

The four-step gear drive gives the spindle a low range starting at 20 rpm, which helps with larger drills and cutters, and the top of the range reaches 20,000 rpm. The table does not state power or torque, so how hard it can cut steel has to be confirmed with Kitamura. The taper is No. 40, which limits tool size and stiffness.

04 How fast are the axes on the Bridgecenter-6G #40?

Rapid traverse is 24 m/min (945 ipm). That is the figure to use when estimating cycle time for parts with holes or pockets spread across the 1,530 mm (60.2 in) X travel, because moves between features take longer than on a small machine.

05 Is there a longer version of this machine?

Yes. The Bridgecenter-8G #40 has 2,032 mm (80 in) of X travel and a 900 x 2,500 mm (35.4 x 98.4 in) table, with the same 1,095 mm (43.1 in) of Y, 710 mm (28 in) of Z and 20 to 20,000 rpm spindle.
