Hyundai WIA KBN1300C

The Hyundai WIA KBN1300C is the flagship of the KBN floor-type CNC horizontal boring machine series, offering the highest spindle power, speed, and torque combined with the largest tool capacity. With a 37/30 kW (50/40 hp) two-step gear-driven spindle producing 3,377/2,739 Nm of torque at 2,500 RPM and a 60-tool ATC, the KBN1300C is built for the most demanding heavy boring and large-part machining applications in power generation, heavy industry, and shipbuilding.

The KBN1300C shares the same 3,000/2,000/1,500/700 mm (118/78.7/59.1/27.6 in) X/Y/Z/W travel envelope and 2,000 x 1,800 mm rotary table as the KBN135 family, but upgrades the spindle from 22/18.5 kW to 37/30 kW and from a three-step to a more efficient two-step gearbox. The result is 3,377 Nm of spindle torque — approximately 8.5% more than the KBN135/135C — combined with a higher 2,500 RPM maximum speed that improves both material removal rate and finish quality.

The 60-tool ATC is a significant upgrade from the 40-tool capacity of the KBN135 models. Complex large-part programs that machine multiple features across several faces often require 30-50 tools, making the expanded ATC capacity essential for uninterrupted production. Table load capacity matches the KBN135C at 15,000-20,000 kg, and rapids of 10 m/min maintain the improved positioning speed.

Box guideway construction throughout ensures the geometric rigidity that extended boring operations demand. At $700,000-$1,100,000 new, the KBN1300C is the premium offering in the Hyundai WIA boring machine lineup. It competes effectively against European floor-type boring machines from TOS Varnsdorf, Skoda, and Pama that typically price well above $1M, making it an attractive option for heavy industry manufacturers seeking world-class boring capability at Korean manufacturing efficiency pricing.
