1HIGH RIGIDITY STRUCTURE
Stable Mechanical Structure
The X-bed, Z-bed, and column are designed with a high-rigidity casting structure to secure a high-rigidity and stable mechanical structure, and the guideway is ground precisely after heat treatment to ensure high stiffness and high precision.
2GUIDE WAY
Hydraulic balance structure of the Y-axis
The hydraulic balance structure features an accumulator charged with high-pressure nitrogen gas, thereby guaranteeing smooth operation and high precision of the Y-axis. In addition, noise has been eliminated and energy can be saved as the machine is not equipped with a hydraulic pump.
Hand Scrapping
The counter surface was hand scraped with Turcite attached, and a linear scale was installed as standard to ensure high precision, realizing the optimal conditions for improving processing quality.
HIGH PRECISION
Std Linear & 1 sec Rotary Scales on All Axis
Linear scales on X/Y/Z-axis and rotary scale on B-axis provide High accuracy positioning and enabling precise machining.
Spindle
Long Lasting, High Accuracy & Excellent Performance
1SPINDLE
High-rigidity Spindle with Excellent Machining Capability
Cutting work can be carried out in conditions of prefect stability as access to the workpiece has been facilitated with the adoption of a nose-type head structure, and the protrusion distance of the boring spindle has been minimized. High-rigidity bearings have been applied to the milling spindle to support the spindle unit. The milling spindle is designed and manufactured to withstand large loads during axial direction machining.
Also, the spindle is equipped with a large-capacity cooling device to maintain stable thermal displacement even during long-term operation, and that cools the gearbox (ZF reducer) and spindle cartridge.
Stable W-axis drive
The boring spindle is applied a W-axis ball screw and 2-way LM guide method. It is driven by a servo motor and a reduction pulley, and equipped with a high-precision encoder to guarantee the degree of feedback..
HIGH CAPACITY SPINDLE COOLING DEVICE
Standard feature high capacity spindle cooling device(5,590kcal/h) enables stabilized spindle temperature during long operations. Stabilized spindle environment leads to high performance and high quality machining.

High Productivity Achieved with High Rigidity, Accuracy Machining
1ATC & MAGAZINE
Reliable Automatic Tool Changer (ATC)
The tool changer consists of a tool magazine and carriage driven by a servo motor to increase reliability. The adoption of a hydraulic cylindrical structure allows it to function stably even when using heavy tools.
2TABLE
NC Rotary Table
To ensure smooth operation of the rotary table under heavy loads, the center shaft is equipped with double roller bearings and thrust ball bearings. Also, the rotary table features a thrust roller bearing structure and a strong bi-directional clamping structure that ensure stable processing conditions.
B-Axis Double Pinion Gear
The drive of the table has a structure in which a gear box and double pinion rotate a large high-precision ring gear.
High-precision encoder is installed at the center of the table as a standard feature, allowing precise control of the index.
