Machining Centers
H6
H6/H8 offer a perfect solution for machining general parts to difficult-to-cutcomponents through high-rigidity, high-precision machining performance.High-productivity, horizontal machining center with a highly rigid structural design to enable hard cutting and maintain precision during prolonged operation.
The application of highly rigid box-way guides and a twin drive system to the X and Y-axis allows processing of general parts as well as difficult-to-cut components, and servo-operated tool and workpiece changers reduce non-cutting time, increasing productivity and enhancing operational reliability and maintainability. Also, 3D design and FEM analysis secured structural stability, while the Hwacheon-developed machining software increases machining efficiency and precision to provide a faster and safer working environment.
Main features
High-Rigidity Mechanical Structure
The highly rigid box-on-box structure supports fast and stable machining, and the machine's minimal installation space requirement is perfect for FA systems.
Highly rigid spindle design
The spindle integrates the motor to limit vibration, noise, and power loss at high speed rotation. The jet of oil is injected directly onto the spindle bearing for effective cooling, and the motor and the spindle assembly are jacket-cooled to limit the displacement caused by heat. To achieve greater precision, the spindle constantly monitors for possible thermal displacement and makes necessary adjustment in real time.
High-Precision Feed System
The roller linear guide feeds a heavy workpiece stably and smoothly, and the direct-coupled servo motor minimizes backlash during the feed. The machine automatically injects set amount of lubricant onto the linear guide and ball screws to maintain precision and smooth feeding.

Mounting software
Hwacheon Tool Load Detect System
"Detect and diagnose the most minute of tool-end point movement"
HTLD constantly monitors the tool wear to prevent accidents, which may occur from a damaged tool and help to stop tool wear from deteriorating the workpiece.
(The load is measured every 8 msec to ensure accuracy.)
Hwacheon High Efficiency Contour Control System
"Roughing quickly, finishing is precisely"
HECC offers an easy to use programming interface for different workpieces and different processing modes.
The system provides a precise,custom contour control for the selected workpiece, while prolonging the life of the machine and decreasing process time. The customizable display provides real-time monitoring and quick access.
Cutting Feed Optimization System
"Maximize your productivity with intelligent system"
OPTIMA utilizes an adaptive control method to regulate the feed rate in real time, to sustain the cutting load during a machining process. As a result the tools are less prone to damage and the machining time is optimized.
Hwacheon Spindle Displacement Control System
"Real-time correction for the displacement in the spindle"
When the spindle rotates at high speed, the centrifugal force drives the taper to expand, causing errors in Z axis. HSDC constantly monitors the temperature at each spindle region and makes optimal prediction for thermal displacement.
The system then makes necessary adjustments and eff ectively minimizing thermal displacement.
Hwacheon Frame Displacement Control System
“System for maintaining processing accuracy for a long period of machining"
HFDC is equipped with highly sensitive thermal sensors in the casting region where thermal activity is suspected; monitoring and correcting displacement.
Hwacheon Thermal Displacement Control System
"Hwacheon Spindle Displacement Control System
+ Hwacheon Frame Displacement Control System"
HTDC integrates the Hwacheon Spindle Displacement Control system and the Frame Displacement Control System.
