2 Table Diameter : 1,600mm Max. Turning Diameter : 2,000mm Max. Turning Height : 1,750mm Table Indexing Degree : 0.001mm CNC Controller : FANUC 18i-TB

3 ** Bed The bed has symmetrical structure horizontally. There is a combination of circular ribs and radial ribs that can withstand axial direction and radial direction load applied to thrust ball bearing and center post. In addition to that, thick panels on top and bottom prevent deformation or vibration. Joining radial ribs and placing triangular ribs from the center significantly increase static rigidity and dynamic rigidity. ** TABLE Casting (GC300) material and its sufficient thickness provide high rigidity. Boring-Mill chuck type is used as standard. It is driven by the spindle motor in the back of bed. Power generated by the motor is transmitted through V-belt. After reducing gear ratio and making high/low 2-speed shift at 2-speed gear box made by Z.F. in the lower part of the motor, master gear is driven through V-belt to turn the table. Table RPM : 1~250 RPM Table torque : 20,269 Nm AC 37/45 kw Max. loading of workpiece : 10,000 kg. T-Slot : 22mm H12 4-Jaw manual chuck. C-axis Gear box

4 ** C-Axis Gear Box Designed minimize backlash to use double pinion gear ** Table Clamp When the milling operate, clamp the table Clamping force : 11 ton C-axis Gear box

5 ** COLUMN Precisely processed column is tightly attached to bed surface and is securely fixed with bolt and horizontal pin. As a box type, the column section was designed symmetrically against the bed center. W-axis slideway is rigid box guide way construction with cast iron and turcite Ball screw : Leadteam (80-lead12) Travel of W-axis : 250mm x 3steps Rapid of W-axis : 500mm/min Gear ratio : 1/30 Servo moter : 7kW (FANUC) ** CROSS RAIL Sufficient height and width of the cross rail provides high rigidity to prevent deformation due to the feed of ram head. Especially, linear bearing slideway of X-axis slideway is composed of induction hardened steel plate. Ball screw : Tsubaki (63-lead12) Travel of X-axis : -250 ~ 1,780 Rapid of X-axis : 15,000mm/min Feed of X-axis : 3,000mm/min Servo motor : 7kW (FANUC) Cross rail moving type **Cross rail clamp Clamping force : 5tons (4 places)

6 ** Saddle The saddle consists of front saddle and rear saddle. The front saddle is inserted into ram head slideway to form z-axis and the rear saddle is inserted into cross rail slideway to from x-axis. Ball screw : Tsubaki (63-lead10) Travel of Z-axis : 1,000mm Rapid of Z-axis : 10,000mm/min Feed of Z-axis : 3,000mm/min Servo moter : 7kW (FANUC) ** Balancing Device Ram head is counter-balanced by the hydraulic cylinder assembled in the saddle. During power outage, it prevents the electronic break attached to z-axis servo motor and the pilot check valve on hydraulic circuit from being dropped. Double balancing cylinder ** Milling operation The gear box for milling operation is located in the upper portion of ram. Gear ratio : 1/3 Spindle moter : 15/18.5kW Spindle torque: 354N.m

7 ** Ram (Z-axis) Ram size : 240 * 240mm Z-axis strock : 1,000mm Hirth coupling type. ** Tool holder clamping Clamping force : 7tons Hirth coupling type. ( Milling attachment )

8 ** Tool-Automatic Tool Changer (ATC) Tools for this equipment are changed automatically by the feed of ram head. After the ram head traverses to tool change position (x-axis) located on the right of the bed, the ram traverses along z-axis and automatically changes the tool holder loaded in the ram. The number of acceptable tools EA (Turning holder : 7ea, Milling attachment : 1ea, Milling tool : 8ea) Magazine drive AC SERVO MOTOR Maximum tool weight kg Maximum tool length mm Milling tool shank BT50 Pull stud bolt P50T-I ** Chip Conveyor Conveyor moter : 0.4kW Coolant tank size : 600l Coolant moter : 1.5kW Coolant pressure : 2bar Coolant filter :540 μm (30 mesh)

9 ** Oil Cooler With complete analysis of parts with heat generation due to rotation of high-density table, separately filtered coolant lubricant is provided at needed spots in order to quickly prevent heat generation which is an excellent way to ensure machine precision Usable type : ISO32 ** Hydraulic Unit Basic pressure at 60 bar, it s used where applicable such as counterbalance cylinder, attachment clamping, C-axis clamping & breaking, etc. In order to provide efficient and stable hydraulic pressure, hydraulic units are mounted both on top and at bottom of the machine, ensuring quick supply as well as compact design. Usable type : ISO32 ** Slideway Lub. Unit This unit jets out at 30 various spots on X, Z and W axis, lubricating each axis to maintain maximum precision of the machine. Usable type : ISO68

10 ** X-axis Guideway Protect Cover Special made slide cover which provides the precision ground slideway with protection from chips, coolant, dust, etc. and it also absorbs impacts from outside. ** Alarm Display Light Equipped at the upper part of the operating panel. Displays in real time the status of the machine such as suspended, operating, finished operating, ready, etc., using 3 colors, allowing the operator to see and maximize the machine s operating efficiency. ** Work Light Mounted on both sides of the table to assure pleasant operating environment and clear view during operation. Wiring cables are located underneath, safe from coolant or any other foreign substances. Gaskets are used at both ends to prevent flooding and it has a form of transparent tube. It has a compact design with outer diameter at 70mm and built in ballast.

11 OPTION PARTS ** Transformer (220V/60Hz) Transforms the 380V~440V power from outside to 220V/60Hz 80KVA. Installed in a separate area. ** Scale Feedback system (X, Z-Axis) Utilizing X, Z-Axis scales, positioning accuracy can be improved Up to ±0.001mm. ** Angular attachment 90dgree angular milling attachment ** Auto Power-off System This function is used to shut off power automatically after unmanned operation is done. This function is set by pressing the button during operation. This function is not operated properly if an emergency stop or alarm occurs during unmanned operation. This function is turned off by pressing the button again.

12 ** Through Spindle Coolant (20bar) Coolant is ejected through the center of the spindle into the cutting tool, quickly ejecting chips inside the hole during deep hole drilling, excellent for prolonging the tool life and preventing tool damage. Maximum pressure : 20bar ** Hydraulic Chuck Easy and fastly to clamp and unclamp the work piece. Clamping force can changeable due to work piece. Size : 63 inch ** Tool setter Machine equipment with tool setter system of tool break and wear.
