1Direct Driven Spindle

By connecting the motor directly to the spindle acc/ dec time was shortened. A wide range of machining can be done with spindle speed of up to 12,000rpm.

Built-in Spindle

The 15,000rpm built-in spindle can minimize vibration transmitted to the spindle. It allows excellent machining performance in mold and high-precision products. Direct Driven Spindle

Standard for Thermal Deformation Compensation(Sensorless)


Compared to competitive machines, the KF4600 has a large working envelope to make setup easier and provide convenience to the operator.

3ATC & Magazine

The tool magazine holds 30 tools as standard and 40 tools as an option. Due to the wider selection of tools and the random tool selection method, tool change time has improved.Tool Change Time (C-C) :3.2 sec

4Optimal Structural Analysis

KF4600 is designed to have optimal structure through Hyundai WIA’s unique structural analysis. In particular, even with heavy cutting increases the rigidity of the bed and column, excellent performance.

Rapid Traverse Rate 36/36/36 m/min
(X/Y/Z) (1,417/1,417/1,417 ipm)

Double anchored ball screw

The precision preloaded ball screw minimizes the expansion and contraction according to the heat and further reinforces the rigidity by the double anchor support method. In addition, the coupling of the ballscrews and the highly reliable digital servo motors are connected by metal plate couplings, and coupling breakage and backlash are reduced.

Direct Driven Spindle

Long Lasting High Accuracy & Excellent Performance

Direct Driven Spindle

The directly coupled spindle at a max rev of 12,000rpm, allows high-speed processing. Additionally, the large diameter and the thickness of the spindle add to the stability of the machine.

Spindle Cooling (12K Std.)

The spindle cooling system minimizes thermal displacement which can happen during lengthy machining operations, and offers continued accuracy based on the thermal stability.

Dual Contact Spindle

The Big Plus spindle system (BBT40) provides dual contact between the spindle face and the flange face of the tool holder.This greatly increases tool rigidity, reduces run out and adds significant productivity to machining applications.

– Tool Lock Type : Hydraulics

Through Spindle Coolant OPTION

Through Spindle Coolant is exceedingly useful when drilling deep holes. It helps increase the lifetime of the tool, while decreasing cycle time.
