i-CUT400T/M Tapping Center

Hyundai Wia, a Korean manufacturer of traditional machine tools that are built with the power of precision and state-of-the-art technology, developed the Vertical Machining Center i-CUT400 Series : a machine that maximizes productivity, while maintaining rigidity and accuracy.

New Leader of Tapping Center

  • High Speed Direct Spindle i-CUT400T : 12,000 [15,000]rpm / i-CUT400M : 24,000rpm
  • Spindle Acce/Deceleration 0 → 24,000 RPM : 1.6 sec.
  • Rapid Feedrate Each Axis 56m/min (Z axis Acce/Deceleration “1.27G”)
  • Rigid Tapping 6,000rpm
  • Weight lightening through structural analysis (2.2t)

Spindle Driving Method



High Speed Rapid Travel

Rapid feedrate has increased to 56 m/min significantly reducing cycle time. Z axis Acce/Deceleration “1.27G”


LM Guideway

Rapid High Speed axis movement is achieved by the use of linear motion guide ways This reduces non-cutting time and decreases machining time for greater productivity. (Z-Axis : Roller LM Guide)

Ball Screw

All axis are driven by high precision double- anchored ballscrews. The double pretension design provides outstanding positioning and repeatability with virtually no thermal growth. All ballscrews are connected directly to the servo drive motors without gears or belts, to eliminate backlash.



Spindle diameter more greatly increases rigidity to the thickness of the spindle. The adoption of high-precision angular contact ball bearings to maintain rigidity and accuracy.


3Servo ATC

The 14 tool Armless Type ATC is standard on the i-CUT400 series. The tool magazine has the option for 21tools

21 Tool Armless Type


High-Precision SpindleLong Lasting High Accuracy & Excellent Performance Tapping Center


1Main Spindle

For high speed spindle, it is designed as high-precision rapid angular ball bearing. Therefore, it exerts excellent performance by realizing rapid processing of Max. 24,000 rpm. (i-CUT400T 12,000 rpm) Reverse rotation double speed reverse (Double Speed Return) hasbeen reduced processing time.

Rigid Tapping

Rigid tapping is standard and eliminates the need for special tooling. Consistent and accurate tapping increases tap life and reduces the machining cycle time.

Spindle Thru CoolantOPTION

Through the spindle coolant is available. This is particularly useful for deep hole drilling and helps increase tool life and decrease cycle time.


Application of 2 Faces Spindle

The Big Plus spindle system (BBT #30) provides dual contact between the spindle face and the flange face of the tool holder. This greatly increase tool rigidity, reduces run out and adds significant productivity to your machining applications.

The increase in standard diameter improves stiffness and ATC repeatability, and Z-axis displacement prevention further extends tool life.


ATC & Magazine High Productivity Achieved with High Rigidity, Accuracy Machining


Magazine & ATC

By adopting magazine of 14 Tool's Armless Type as standard specification, non-cutting time is minimized by promptly exchanging tools (1.6 sec for Tool to Tool and 1.89 sec for Chip to Chip). In addition, as option, tool range is largely extended because 21 Tool's Armless Type magazine can be selected.

Servo ATC

Applied servo motor driven ATC to reduce tool change time. Also, accurate tool positioning control increases cutting stability.
