KF760BM Excellent Cutting Capability & Productivity for Mold Machining

The Vertical Machining Center KF760BM, designed by Hyundai WIA with years of expertise and the latest technology, maximizes productivity while maintaining rigidity and accuracy.

The Fastest, the Most Versatile High end Linear Machining Center

  • Built-in spindle for a high-quality mold processing
  • Excellent vibration absorption through box guideways in all axes
  • Decrease of travel load with semi-air-floating slide way
  • Prevent vibration fundamentally by seperated column and magazine
  • Mold pacakage for precise machining (option)

Basic Features

Excellent Cutting Capability & Productivity for Mold Machining

KF760BM

Travel (X/Y/Z) 1,550/760/720 mm
(61″/30″/28.3″)
Rapid Traverse Rate (X/Y/Z) 16/16/12 m/min
(630/630/472 ipm)

1Built-in Spindle

Designed with a built-in motor structure, the spindle achieves maximum acceleration and deceleration by suppressing vibration and heat that can occur during high-speed rotation, and maintains stable accuracy even under high-speed heavy duty cutting.

※Thermal Displacement Compensation as Standard

Enhanced Rigidity by Weight Reduction

Especially, over-hang problem is decreased due to weight reduction(10%) of main spindle compare to the previous model to achieve high-quality mold machining.

2Table

Compared to competitive machines, the KF760BM has a large working capacity to make setup easier and provide convenience to the operator.

Model KF760BM
Size 1,800×700 mm (70.9″x27.6″)
Load Capacity 2,000 kg (4,409 lb)

4Optimal Structural Analysis

KF760BM is designed to have optimal structure through Hyundai WIA's unique structural analysis.In particular, enhancement of bed and column's rigidity makes excellent performance even in heavy duty cutting.

Increased Rigidity through Structural Analysis

Compared to the previous model

X Axis : 115% UP Y Axis : 164% UP Z Axis : 162% UP

Slideway

Heavy Duty Cutting by High-Rigid & Accurate Mechanism

images

Air Semi-Rising Slideway

By applying the air semi-rising slideways, the load on the X/Z-axis slideway is decreased. Therefore, positioning and repeatability accuracy can be maintained for a long time.

One Piece High Column Structure

Additional 250mm(9.8″) extension can be applied on the KF760BM as an option.

KF760BM (A~B)

Distance from Table Top to SP. Nose 200~920 mm
(7.9″~36.2″)

KF760BM High Column (A~B)OPTION

Distance from Table Top to SP. Nose 450~1,170 mm
(17.7″~46″)

Double anchored ball screw

The pretensioned 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, to reduce coupling breakage and backlash.

Built-in Spindle

Long Lasting High Accuracy & Excellent Performance

High-precision Built-in Spindle

By using ultra precision angular ball bearings, fast acceleration and deceleration of the main spindle is achieved. The spindle head is designed to minimize the heat displacement of main spindle, and with the use of hydraulic tool lock system, the machining stability has increased.

12,000rpm

Spindle Output 30/25 kW (Max./Cont.)
Spindle Torque 420/238 N.m (Max./Cont.)
(309.8/175.5 lbf.ft)

Spindle Cooling

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

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.

(290 psi / 435 psi / 1,015 psi)

Dual Contact Spindle

The Big Plus spindle system 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.
