KF-II SeriesHigh Speed & High Productivity Vertical Machining Center
The KF-II Series is a vertical machining center that is a great improvement on the existing KF series, Hyundai Wia's steady seller. By providing high-precision machining through quality improvement of the spindle and customized machining through various spindle line-ups, this product will contribute to maximizing customer productivity.
Most Versatile Vertical Machining Center
Basic Features
High-speed & high-productivity state-of-the-art vertical machining center
1Spindle Optimized For Machining
The machining tool’s spindle is structurally optimized to dramatically improve the spindle vibration and acceleration / deceleration compared to the previous model, providing the best machining quality.
58% reduction in spindle vibration compared to existing models
Spindle acceleration / deceleration increased by 19%
2Integral High Column Option
The height of the Z-axis can be extended when the integral high column provided as an option is applied.
Significantly improved rigidity compared to competitor’s block-type high columns
