Large Machining Area

KL7000/8000LY features the largest machining area in its class, increasing the size of parts that can be machined.

1High Rigidity Flat Bed Structure

images

KL7000/8000LY is designed with a unique structure analysis only offered by Hyunda i Wia in the flat bed structure unlike the existing slant bed, resulting in improvements in strong and heavy-duty cutting capability.

Up to 25% additional ridigity compared to slant type bed

2Wedge Type Y-axis Structure

The wedge type Y-axis offering superb positional accuracy and rigidity ensures increased productivity.

Powerful Cutting Capability & Large Working Area

Rapid Traverse Rate (X/Y/Z axis) 12/10/12 m/min (472/394/472 ipm)
Travel (X/Y/Z axis) 500/220/3,280 mm (19.7″ / 8.7″ / 129″)

4BMT 85P Turret (Mill Turret)

The BMT turret, with 4 screws solidly fixes the holder, showing outstanding performance in powerful cutting applications and is capable of machining complex products by using milling tools.

1Main Spindle

To accomplish stability even during the heavy-duty cutting, the spindle is designed with a combination of P4 level double cylindrical roller bearings and angular bearings.

The spindle is equipped with a high torque gear box showing the strength in the heavy-duty cutting. In addition, heat dissipation ribs and fan are attached to the front/rear side making heat discharge faster.

Spindle Gear Box

Gear shift of spindle provides stability and high torque during low speed.
