Overview
The Hyundai WIA KF4608/5608/5608L/6708 is a family of high-speed vertical machining centers spanning four table-size configurations to cover a wide range of production applications. The KF4608 is the most compact, the KF5608 offers mid-range travels, the KF5608L extends the X-axis for longer parts, and the KF6708 provides the largest work envelope in the series. All four models share a common platform architecture with linear roller guideways and high-speed spindle technology.
The KF4608 provides travels of 600 x 460 x 510 mm on a 1,020 x 460 mm table, stepping up through the KF5608 at 1,050 x 560 x 520 mm on a 1,250 x 560 mm table, the KF5608L extending X-travel to 1,300 mm for long-bed applications, and the KF6708 topping out at 1,300 x 670 x 625 mm on a 1,500 x 670 mm table. All models feature HSK-A63 direct-drive spindles at 12,000 RPM standard, with 15,000 and 20,000 RPM high-speed options available.
Rapid traverse rates reach 48 m/min (1,890 ipm) across the lineup, which is competitive with the fastest VMCs in each size class. The servo-driven arm-type ATC provides 30 tools standard (40 optional) with fast chip-to-chip times. The FANUC 0i-MF Plus control is standard across all four models, ensuring consistent programming and operator training across a multi-machine shop.
Pricing ranges from approximately $95,000 for the compact KF4608 to $200,000+ for a fully optioned KF6708, making this family a cost-effective way to standardize on a single VMC platform across different part sizes. The shared spindle, control, and tooling compatibility across all four models simplifies tooling inventories, operator training, and maintenance procedures. This family competes with the DN Solutions DNM series, Haas VF series, and Mazak VCN series across the size spectrum.

Strengths & Limitations
Strengths
- Four table sizes on a common platform let shops standardize tooling, training, and maintenance across different part-size requirements
- HSK-A63 spindle interface as standard provides superior high-speed rigidity across all models in the family
- 48 m/min rapid traverse is among the fastest in each respective size class, minimizing non-cutting time
- KF5608L long-bed variant provides 1,300 mm X-travel for shops machining elongated parts without jumping to a bigger machine class
- FANUC 0i-MF Plus control across all models ensures consistent programming and seamless operator transitions between machines
- Competitive pricing across the lineup undercuts comparable Japanese VMC families by 15-25%
Limitations
- HSK-A63 tooling costs 40-60% more than BT40/CT40, adding to initial investment when equipping multiple machines
- The multi-model family designation can create confusion for buyers — carefully match travels and table size to your specific part requirements
- Hyundai WIA North American service network is smaller than Haas or Mazak, which may affect response times in some regions
- Standard 30-tool ATC may limit complex programs requiring many unique tools across all models

Frequently Asked Questions
01
Choose the KF4608 for compact parts under 600 mm X-travel. The KF5608 covers mid-size work up to 1,050 mm. The KF5608L extends to 1,300 mm X-travel for long parts that the KF5608 cannot reach. The KF6708 adds wider Y-travel (670 mm) and deeper Z-travel (625 mm) for the largest parts in the family. Match your most common part dimensions to the smallest machine that fits.
02
Yes. All four models use the same HSK-A63 spindle interface, so toolholders, collet chucks, and cutting tools are fully interchangeable. This is a major advantage for multi-machine shops, as it consolidates the tool crib and simplifies tool management across the production floor.
03
The KF4608 starts around $95,000-$130,000, while the KF6708 typically ranges from $160,000-$200,000+ depending on options. The KF5608 and KF5608L fall in between at $120,000-$170,000. The price difference reflects the larger castings, wider guideways, and heavier construction of the bigger models.
04
Yes. All four models support the addition of bolt-on 4th-axis rotary tables for indexed or continuous 4-axis machining. The FANUC 0i-MF Plus control supports 4th-axis interpolation. Table size and workpiece clearance should be verified against the specific rotary table model to ensure compatibility.
