1 G-8 ERIE Heavy Duty upersize CNC Turning Centers

2 G-8 eries Construction pindle Turret HEAVY DUTY UPERIZE CNC TURNING CENTER With leading technologies and high quality components, the G-8 series heavy duty CNC turning center combines a high rigidity box way bed with extra large diameter servo indexing turret and powerful gear spindle structure to provide you with efficient machining performance for large diameter and extra long work pieces. Meanwhile, with the optional live tooling turret and Y-axis, the G-8 series can easily accomplish multi-tasking operations for large and complex work pieces to fulfill various machining needs for today and tomorrow. 3-step gear box is driven by FANUC spindle motor with 45 kw maximum torque to provide excellent heavy duty cutting capability. The low center of gravity slant bed and wedge saddle design provide a super rigid structure. The optional Y-axis travel is of 32 mm which provides high precision and high efficiency machining performance. Fully enclosed splashguards keep chips and coolant contained for a safe clean working environment.

3 Multi-tasking Dimensions Features pecifications The MT#6 built-in bearing quill provides greater rigidity for heavy loads. The extension and retraction of the quill is programmable and pressure is adjustable. The software simplifies the positioning procedure of the programmable tailstock. Working with the live tooling turret and C-axis control enables the machine to perform multiple tasks such as turning, milling, drilling, and tapping. It can prevent machining error causing by moving the work piece from one machine to another thus saving cycle time and manpower. The optional hydraulic steady rest can support work pieces up to Ø 46 mm diameter, which provides the best support for large work piece. ( G-8L2 series model shown with optional accessories. )

4 G-8 eries Construction pindle Turret HIGH RIGIDITY CNTRUCTIN The low center of gravity heavy duty slant bed design provide a super rigid foundation for the headstock, turret, and tailstock. By using Finite Element Methods ( FEM ), optimal reinforce ribbings are directly cast into the one-piece bed structure. Mechanical rigidity has been increased by more than % when compared to conventional designs. The G-8 series can provide both heavy cutting and high precision capabilities. More rigidity also means extended tool life. 32 mm Built to endure years and years of rigorous high production turning, the heavily ribbed, one-piece thermally balanced bed and casting components are of MEEHANITE casting. MEEHANITE grade cast iron is capable of withstanding much greater stress without deforming and provides maximum vibration damping, which result in a machine that will outlast and outperform the competition. All spindle and servo motors, including drives, are FANUC alpha i series components to ensure peak machining performance and accuracy.

5 Multi-tasking Dimensions Features pecifications C3 class hardened and precision ground ball screws ensure the highest accuracy and durability possible. Plus, pretension on all axes minimizes thermal distortion. Extra wide hardened and ground box ways are directly formed into the machine bed and saddle during the casting process. They are precision machined and widely spaced for maximum strength. The box way design also provides the rigidity needed for heavy duty and interrupted turning applications. The oil mist system can evenly and efficiently lubricate the spindle bearings to prevent thermal expansion while ensuring machining accuracy. ( Casting structure of G-8L2Y model shown. )

6 G-8 eries Construction pindle Turret ULTIMATE TURNING PWER High precision bearings are directly assembled for maximum level of support and precision. Bearing configuration is designed for heavy-duty cutting with ultra-smooth performance and long term durability with a higher level of accuracy. With over 7,3 N-m of torque available on the low speed of the 3-speed gear box, turning tough material with big diameter is now a simple task. tandard spindle orientation feature allows the spindle to stop at desired programmed position. Useful in broaching and manual part loading applications where a fixed spindle position is required. ample Work Pieces PULLEY Material : FC CYLINDER Material : 45C TURRET HEAD Material : FCD WHEEL Material : Aluminum PINDLE Material : CM21H BRAKE DIC Material : ATM G CUPLING Material : CM 415

8 G-8 eries Construction pindle Turret ADVANCED TURRET TECHNLGY The curvature of the CURVIC teeth provides a very unique selfcentering feature and wider uniform tooth contact throughout all the teeth. The CURVIC teeth are hardened to HRC 58, which ensures the coupling retains its high accuracy characteristics over long periods of use. Ø 4 mm diameter super high precision CURVIC couplings with 12, Kg of clamping force ensures abundant turret rigidity for all cutting conditions. The 12-station heavy-duty servo indexing turret achieves.5 second indexing times for adjacent stations and 1.5 second times for stations at the opposite end of the disk turret. The standard 12-station turret is capable of turning Ø 38 mm diameter work pieces without causing interference even when using boring tools. Concave Curvic Coupling Convex LIVE TLING TURRET Working with the live tooling turret and C-axis control enables the machine to perform multiple tasks such as turning, milling, drilling, and tapping. It can prevent machining error causing by moving the work piece from one machine to another thus saving cycle time and manpower. More powerful than a standard -taper machining center, the live tooling turret is driven by a 9 kw ( min. ) AC double wound high torque spindle motor to provide ample power, now, even the toughest of jobs may be tackled without a sweat. The 12-station live tooling turret offers 12 stations available for live tooling, live tools rotate in working position only to reduce power loss and heat. GDWAY live tooling turret utilizes advance servo indexing technology to achieve.5 second indexing times for adjacent stations and 1.5 second for stations at the opposite end of the disk.

Working with the live tooling turret, the Cf-axis and disk brake system enables the machine to perform multiple tasks, such as drilling, tapping, and milling operations, including cylindrical and polar coordinate interpolations, resembling a 4th-axis rotary table on a machining center. With the FANUC servo motor generating an ultra high resolution of 1,, pulses per spindle rotation and high torque, machined surface finishes are much superior than Cs-axis ( driven by spindle motor ) equipped machines. Plus, dynamic accuracy is within ±.2 even under heavy cutting loads.
