Overview
The Hyundai WIA KF5600M and KF6700M are high-speed variants of the KF-series vertical machining centers, designated with the M suffix for their upgraded spindle options targeting faster aluminium and light-alloy machining. Built on the same proven platforms as the standard KF5600 and KF6700, these M-variants feature higher-speed spindle configurations (15,000-20,000 RPM) while retaining the structural rigidity and travel envelopes that make the KF series popular in production environments.
The KF5600M offers 1,100 x 560 x 520 mm (43.3 x 22.0 x 20.5 in) travel with a 1,250 x 560 mm table, while the KF6700M steps up to 1,300 x 670 x 520 mm (51.2 x 26.4 x 20.5 in) travel with a 1,500 x 670 mm table. Both use HSK-A63 spindle interfaces as standard, providing the rigidity and balance stability that high-speed operation demands. The HSK interface tightens under centrifugal force at high RPM, unlike BT tapers that can loosen.
Rapid traverse rates of 36-42 m/min (1,417-1,654 ipm) in X/Y and 30-36 m/min (1,181-1,417 ipm) in Z maintain competitive non-cutting times on long-travel programs. The 30-tool arm-type ATC (40-tool optional) delivers fast tool changes for complex multi-operation programs. Linear roller guideways on all axes balance speed and precision for both roughing and finishing operations.
The FANUC i-Series control provides nano-interpolation for smooth surface finishes on contoured parts. At $100,000-$160,000 new depending on model and spindle configuration, the KF5600M/6700M series offers high-speed VMC capability at Korean value pricing. These machines target shops where aluminium is the primary workpiece material but occasional steel work is still required.

Strengths & Limitations
Strengths
- 15,000-20,000 RPM high-speed spindle options deliver the surface speeds needed for productive aluminium machining with excellent finishes
- HSK-A63 spindle interface provides superior high-speed rigidity and balance versus BT40 competitors in this price range
- Two size options (5600M and 6700M) let buyers match travel and table size to workpiece requirements
- 15-25% lower pricing than comparable Mazak, Okuma, and DMG Mori high-speed VMCs
- Direct-drive spindle eliminates belt-related vibration and maintenance for cleaner surface finishes at high RPM
- Linear roller guideways balance the speed demands of high-speed machining with positioning accuracy for tight tolerances
Limitations
- HSK-A63 tooling costs 40-60% more than BT40, impacting total investment for shops building a new tool library
- 520 mm Z-travel limits workpiece height and long-tool reach for deep-cavity or tall-part applications
- High-speed spindle options reduce maximum torque at low RPM, limiting heavy roughing capability in steel
- Hyundai WIA brand recognition in the high-speed VMC segment is lower than Makino, Okuma, or Mazak

Frequently Asked Questions
01
The KF6700M offers 200 mm more X-travel (1,300 vs 1,100 mm) and 110 mm more Y-travel (670 vs 560 mm) with a proportionally larger table. Choose the KF5600M for parts within its travel envelope to minimise footprint and cost; step up to the KF6700M for larger workpieces, multi-fixture setups, or tombstone applications that demand the extra travel.
02
The M variants are configured for high-speed machining with 15,000-20,000 RPM spindle options versus the standard 12,000 RPM. For shops where aluminium is the primary material, the higher spindle speed translates directly to shorter cycle times through higher surface speeds. For steel-dominant shops, the standard models with lower RPM and higher torque may be more appropriate.
03
Both target the high-speed VMC segment. Makino PS-series machines are highly regarded for high-speed aluminium work with excellent thermal stability and accuracy. The KF M-series counters with competitive specifications at significantly lower pricing. For shops where Makino-level accuracy justifies the premium, the PS wins; for production-focused shops optimising ROI, the KF M-series offers strong value.
04
Yes. While optimised for high-speed aluminium work, the HSK-A63 spindle with 18.5 kW power provides adequate torque for steel machining at lower RPM. The machines are not pure high-speed aluminium machines. They are versatile VMCs with high-speed spindle options. Most shops use them for mixed-material production with aluminium as the primary material.
