Overview
The Hyundai WIA KH500 is a 500 mm pallet horizontal machining center designed for production machining of medium-to-large prismatic components in demanding manufacturing environments. With a 500 mm square pallet, 630/630/630 mm (X/Y/Z) travels, and a 12,000 RPM BT50 spindle with 30/22 kW (40/30 hp), the KH500 targets the high-volume production HMC segment alongside the Mazak HCN-5000, Okuma MA-500H, and DMG Mori NHX 5000.
The step up from the KH400 to the KH500 brings a larger pallet, more Y- and Z-travel, and critically, a BT50 spindle that provides substantially higher torque at low RPM — essential for productive heavy roughing in steel, cast iron, and titanium that is common in aerospace, heavy equipment, and automotive structural component machining.
The two-pallet APC maintains the continuous-cutting strategy that defines productive HMC operation. A 60-tool chain-type ATC provides ample tooling for complex multi-side programs. Rapid traverse of 50 m/min (1,969 ipm) in all axes is competitive for the 500 mm class. FANUC 0i-MF Plus with full B-axis support is standard.
Hyundai WIA's KH500 is constructed on a heavily ribbed one-piece cast iron base optimized for thermal stability and long-term geometric accuracy. At $380,000-$520,000 new, the KH500 is priced competitively against European and Japanese 500 mm HMCs. For automotive, aerospace, and heavy equipment manufacturers running medium-to-high production volumes on large prismatic parts, the KH500 delivers proven HMC productivity at a compelling price point.

Strengths & Limitations
Strengths
- BT50 spindle taper provides high torque at low RPM for productive heavy roughing in steel, cast iron, and titanium
- 630/630/630 mm cubic travel envelope accommodates large prismatic components that exceed KH400 capacity
- 30 kW (40 hp) spindle delivers strong material removal rates for high-volume production of large machined components
- 2-pallet APC enables continuous cutting and dramatically improves spindle utilization in production environments
- 60-tool chain ATC provides complete tooling flexibility for complex 4-side machining programs
- Heavy cast iron base with thermal compensation ensures long-term geometric accuracy across extended production runs
- Competitive pricing at $380K-$520K versus comparable Mazak HCN-5000 and Okuma MA-500H
Limitations
- $380K-$520K capital cost is significant — requires high-volume production of complex parts to justify the investment over a VMC
- 26,000 kg machine weight demands a heavily engineered foundation and crane access for installation
- 12,000 RPM maximum speed is appropriate for the BT50 taper but limits high-speed aluminum applications compared to BT40 HMCs
- 50 m/min rapids are competitive but slightly below the KH400's 60 m/min — the larger mass of the KH500 reduces achievable acceleration
- Hyundai WIA's 500 mm HMC after-sales infrastructure is less mature than Mazak or Okuma — evaluate regional support capacity before committing

Frequently Asked Questions
01
New KH500 horizontal machining centers typically sell in the $380,000-$520,000 range depending on options, automation packages, and regional dealer pricing. Used 500 mm HMCs in good condition typically trade between $200,000-$350,000. HMC pricing varies significantly based on ATC configuration, pallet automation level, and included accessories.
02
The KH500 provides a larger 500 mm pallet (vs 400 mm), more travel in all axes (630/630/630 vs 500/560/500 mm), and critically, a BT50 spindle taper with 30 kW (40 hp) that delivers substantially more torque at low RPM than the BT40 KH400. Choose the KH500 when your parts exceed 400 mm pallet size, when heavy cutting in steel or titanium demands more spindle torque, or when workpiece weight exceeds the KH400's rated limit.
03
4-side machining refers to the ability to machine four faces of a prismatic workpiece in a single setup using the B-axis rotary table. The KH500's B-axis indexes the pallet in 1-degree increments (0.001° continuous optional), rotating the part to present each face to the horizontal spindle. This eliminates the need to re-fixture the part between operations on different faces, reducing setup time, improving positional accuracy, and cutting work-in-process significantly.
04
Yes. The KH500's BT50 spindle with 30 kW and high torque at low RPM is well suited for titanium machining, which requires low cutting speeds, high chip loads, and excellent chip evacuation. High-pressure through-spindle coolant (optional) improves chip breaking and tool life in titanium. The horizontal orientation of the KH500 also aids chip evacuation relative to a VMC — an important factor in long titanium programs where chip re-cutting is a major tool life concern.
05
The KH500's 26,000 kg weight requires a reinforced concrete foundation with a minimum depth of 500-700 mm depending on soil conditions, with anchor bolts at Hyundai WIA's specified locations. Leveling pads and precision leveling are required during installation. A structural engineer should review floor load-bearing capacity before installation. Hyundai WIA provides complete installation drawings specifying anchor patterns, utility connections, and floor load requirements.
