How much does the Hyundai WIA KBN135C cost?

Estimated price range

Est.$600,000 - $900,000

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

Overview

Listed for a 15,000 kg (33,069 lb) table load, with 20,000 kg (44,092 lb) as an option, the Hyundai WIA KBN135C is a CNC boring machine that shares its 135 mm (5.3 in) spindle and 2,000 x 1,800 mm (78.7 x 70.9 in) table with the KBN135 but is listed for more weight and faster rapids. Hyundai WIA's current lineup does not include it, so this page serves someone sizing up a used machine, and the listed figures need confirming on that machine.

On paper it differs from its sister model in two rows. The table load is 15,000 kg here against the 10,000 kg (22,046 lb) listed for the KBN135. The rapids are 10/10/10 m/min (394 ipm) here against the 8/8/8 m/min (315 ipm) of the KBN135. Everything else is listed alike: 3,000 mm (118 in) of X, 2,000 mm (78.7 in) of Y, 1,600 mm (63 in) of Z and 700 mm (27.6 in) of W, a BT50 taper, a three-step gear drive to 2,000 RPM, box guideways, 40 tools and a Fanuc 0i-MF Plus control.

The load and rapid figures are the same ones the current KBN1300C carries: 15,000 kg standard, 20,000 kg optional, and 10 m/min in X, Y and Z. The KBN1300C differs with 1,500 mm (59.1 in) of Z, a 2,500 rpm ISO #50 spindle and a 60-tool magazine, which makes it the natural yardstick when judging whether an older KBN135C still fits the work.

Strengths & Limitations

Strengths

Listed table load of 15,000 kg (33,069 lb), with 20,000 kg (44,092 lb) optional
Rapids of 10/10/10 m/min (394 ipm), against 8/8/8 m/min (315 ipm) listed for the KBN135
1,600 mm (63 in) of Z travel, more than the 1,500 mm (59.1 in) of the current KBN1300C
135 mm (5.3 in) spindle with a BT50 taper, a three-step gear drive and box guideways

Limitations

Absent from Hyundai WIA's current lineup, so every listed figure needs checking on the actual machine
Whether a given machine has the 20,000 kg (44,092 lb) table option must be confirmed; 15,000 kg (33,069 lb) is the standard listing
The 40-tool magazine and 2,000 RPM spindle are below the 60 tools and 2,500 rpm of the current KBN1300C
No spindle power or torque figure is listed

Frequently Asked Questions

01 How does the KBN135C differ from the KBN135?

The KBN135C is listed with a 15,000 kg (33,069 lb) table load and 10/10/10 m/min (394 ipm) rapids. The KBN135 is listed with 10,000 kg (22,046 lb) and 8/8/8 m/min (315 ipm). The table, the travels, the 135 mm (5.3 in) spindle, the BT50 taper and the 40-tool magazine are listed the same on both.

02 How much weight can the KBN135C table carry?

The standard listing is 15,000 kg (33,069 lb), with 20,000 kg (44,092 lb) as an option. On a used machine the option may or may not be fitted, so read the rating from the machine's plate or build sheet and include fixtures and risers in the total.

03 How does the KBN135C compare with the current KBN1300C?

Both have a 2,000 x 1,800 mm (78.7 x 70.9 in) table, 3,000 mm (118 in) of X, 2,000 mm (78.7 in) of Y and 700 mm (27.6 in) of W. The KBN1300C has 1,500 mm (59.1 in) of Z against 1,600 mm (63 in) here, a 2,500 rpm ISO #50 spindle against 2,000 RPM on BT50, and 60 tools against 40. The KBN1300C is also listed with 3,377 / 2,739 N·m (2,490.9 / 2,020.3 ft-lbf) of spindle torque, where no torque is listed for the KBN135C.

04 What spindle and tooling does the KBN135C have?

A 135 mm (5.3 in) spindle with a BT50 taper, driven through a three-step gear drive to a maximum of 2,000 RPM. The magazine is listed at 40 tools. Spindle power and torque are not listed, so take the motor rating from the machine itself before planning heavy cuts.
