Our best estimate for a cnc boring machine in this class — not a quote from Hyundai WIA. Configuration moves it a long way.

Overview

The Hyundai WIA KBN135 is a CNC boring machine with a 135 mm (5.3 in) boring spindle, a 2,000 x 1,800 mm (78.7 x 70.9 in) table and a listed table load of 10,000 kg (22,046 lb). It is not in Hyundai WIA's current lineup, so anyone considering one is looking at a used machine and should check the listed figures against the machine's own plate and manuals.

Listed travels are 3,000 mm (118 in) in X, 2,000 mm (78.7 in) in Y and 1,600 mm (63 in) in Z, plus 700 mm (27.6 in) on the W axis. The spindle has a BT50 taper, a three-step gear drive and a 2,000 RPM maximum. No power or torque figure is listed, so cutting capacity has to be established from the machine's documentation. Box guideways carry the axes, with rapids of 8/8/8 m/min (315 ipm). The magazine is listed at 40 tools and the control as Fanuc 0i-MF Plus.

Two comparisons help place it. The KBN135C is listed with the same table, travels and spindle but a 15,000 kg (33,069 lb) table load and 10/10/10 m/min (394 ipm) rapids. The current KBN1300C keeps the 2,000 x 1,800 mm table and the 3,000 mm X and 2,000 mm Y travels, with a 2,500 rpm ISO #50 spindle and a 60-tool magazine.

Limitations

Not in Hyundai WIA's current lineup; the listed figures should be confirmed on the individual machine
Listed table load of 10,000 kg (22,046 lb) is below the 15,000 kg (33,069 lb) listed for the KBN135C
Rapids of 8/8/8 m/min (315 ipm) and a 2,000 RPM spindle limit make it slow on long moves and small tools
No spindle power or torque is listed

Best For

Frequently Asked Questions

01 Is the KBN135 in Hyundai WIA's current lineup?

No. The KBN135 is not in the current lineup, so it is a machine found used. A current boring machine with the same table size is the KBN1300C, which has a 2,000 x 1,800 mm (78.7 x 70.9 in) table and 3,000 mm (118 in) of X travel with a 2,500 rpm spindle and 60 tools.

02 What is the difference between the KBN135 and the KBN135C?

In the listed figures, table load and rapid rate. The KBN135 is listed at 10,000 kg (22,046 lb) and 8/8/8 m/min (315 ipm). The KBN135C is listed at 15,000 kg (33,069 lb), with 20,000 kg (44,092 lb) optional, and 10/10/10 m/min (394 ipm). Table size, travels, spindle diameter, taper and tool count are listed the same for both.

03 What are the travels and table size of the KBN135?

The table is 2,000 x 1,800 mm (78.7 x 70.9 in). Listed travels are 3,000 mm (118 in) in X, 2,000 mm (78.7 in) in Y, 1,600 mm (63 in) in Z and 700 mm (27.6 in) in W. These are listed figures for a model no longer in the lineup, so measure the strokes on the machine you are inspecting.

04 What should I check on a used KBN135?

Start from the listed figures. Run the spindle through all three gear steps up to 2,000 RPM, move each axis over its full listed travel, and read the table load from the machine's plate, since 10,000 kg (22,046 lb) is listed for the KBN135 and 15,000 kg (33,069 lb) for the KBN135C. The spindle motor rating is not listed, so take it from the motor plate.
