Our best estimate for a vertical machining centers (vmc) in this class — not a quote from Kitamura Machinery. Configuration moves it a long way.

Overview

With a No. 50 taper spindle over a 900 x 1,800 mm (35.4 x 70.9 in) table rated for 3,000 kg (6,600 lb), the Kitamura Bridgecenter-6G #50 is the build of this vertical machining center for heavy metal removal on large plates, mould bases and die blocks.

Its spindle runs from 35 to 12,000 rpm through a four-step gear drive. In low gear a 50-taper spindle carries large face mills and long, stiff boring tools that a smaller taper cannot hold rigidly, and the 12,000 rpm top end still allows a finishing pass in the same setup. The standard taper is NST No. 50, with HSK-A100 optional. Neither power nor torque is stated in the table. Request both, since they decide the largest cutter worth buying.

Axis 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. The 710 mm of Z has to be shared between the workpiece, the fixture and the tool, and 50-taper tools are long, so lay out a tall die block with its longest tool before ordering. The magazine holds 40 tools as standard, with 60 and 80 tool versions optional.

Rapids are 24 m/min (945 ipm). On roughing work that is rarely the limiting figure, because the time goes into the cut. Listed accuracy is ±0.002 mm (±0.000079 in) over the full stroke and ±0.001 mm (±0.000039 in) repeatability, and the supply is 35 kVA at 200 V AC, three-phase. When parts outgrow this table, the Bridgecenter-10G has 2,540 mm (100 in) of X, 1,615 mm (63.6 in) of Y and 800 mm (31.5 in) of Z over a 1,370 x 3,000 mm (53.9 x 118.1 in) table.

Strengths & Limitations

Strengths

No. 50 taper spindle with four-step gear drive, covering 35 to 12,000 rpm
Table load capacity of 3,000 kg (6,600 lb) on a 900 x 1,800 mm (35.4 x 70.9 in) table
1,095 mm (43.1 in) of Y travel, more than the table width, for full-width facing of plates
40 tool magazine as standard, with 60 and 80 tool magazines available
±0.002 mm (±0.000079 in) accuracy over the full stroke and ±0.001 mm (±0.000039 in) repeatability

Limitations

Z travel is 710 mm (28 in), which long 50-taper tools and tall workpieces use up quickly
Spindle power and torque are not listed, so cutting capacity must be confirmed before purchase
Rapid traverse is limited to 24 m/min (945 ipm)
Top speed is 12,000 rpm; the Bridgecenter-6G #40 runs to 20,000 rpm for small cutters

Best For

Mould bases and die blocks up to 3,000 kg (6,600 lb) Heavy face milling and boring in steel with 50-taper tooling Steel plate work across a 900 x 1,800 mm (35.4 x 70.9 in) table Roughing and finishing in one setup, from 35 to 12,000 rpm

Frequently Asked Questions

01 What spindle is on the Bridgecenter-6G #50?

An NST No. 50 taper spindle with a four-step gear drive and a speed range of 35 to 12,000 rpm. HSK-A100 is the optional taper. Kitamura's table for this model does not give spindle power or torque, so ask for the output in each gear step.

02 How heavy a workpiece can the Bridgecenter-6G #50 take?

Table load capacity is 3,000 kg (6,600 lb) on a table of 900 x 1,800 mm (35.4 x 70.9 in). Remember that the limit covers the fixture, parallels and clamps as well as the workpiece.

03 Should I pick the #50 or the #40 spindle on the Bridgecenter-6G?

Choose by tooling. The Bridgecenter-6G #50 takes No. 50 taper holders and runs from 35 to 12,000 rpm, which favours large cutters in steel. The Bridgecenter-6G #40 takes No. 40 taper holders and runs from 20 to 20,000 rpm, which favours small cutters and light alloys. The table and travels do not change.

04 How many tools does the changer hold?

40 tools as standard. Magazines of 60 and 80 tools are optional. For die and mould work, where roughing, semi-finishing and finishing cutters all stay loaded, it is worth counting the tool list before settling on the standard magazine.

05 What is the next larger Bridgecenter?

In length, the Bridgecenter-8G #50 has 2,032 mm (80 in) of X on a 900 x 2,500 mm (35.4 x 98.4 in) table. For more width and height, the Bridgecenter-10G has 2,540 mm (100 in) of X, 1,615 mm (63.6 in) of Y and 800 mm (31.5 in) of Z.
