Product Specifications
Worktable & Load Capacity
At the heart of the GT-1715 lies a robust worktable designed for stability and versatility. With worktable dimensions of 1200*1700 MM, it provides ample surface area for large workpieces, while its 7 T-slots (22*170 MM) ensure secure clamping for diverse machining tasks. The table supports a maximum load of 2.5 T, making it suitable for heavy materials like cast iron and alloy steel. Additionally, the distance from the spindle end face to the worktable ranges from 150-950 MM, accommodating varying workpiece heights with ease.
Axis Travels & Gantry Design
The GT-1715 offers extensive axis movements to handle complex machining needs. The X-axis (worktable movement) provides 1700 MM of travel, while the Y-axis (spindle slider movement) offers 1500 MM, and the Z-axis (spindle vertical movement) delivers 800 MM—ensuring comprehensive coverage for large-scale parts. The machine’s gantry width of 1500 MM enhances structural stability, critical for minimizing vibration during high-torque operations.
Spindle & Drive Systems
Powered by a high-performance spindle, the GT-1715 excels in both roughing and finishing. Its BT50 spindle (190 MM installation diameter) is compatible with a wide range of tools, operating at a maximum speed of 6000 RPM for versatile cutting. The spindle and X/Y/Z axis servo motors deliver 18.5 KW of power, ensuring sufficient torque for heavy-duty cutting while maintaining precision.
Motion Control Components
Precision is guaranteed by the GT-1715’s advanced motion systems. All axes feature 5010 ball screws (X:5010; Y:5010; Z:5010), pre-tensioned to reduce backlash and enhance positioning accuracy. The X and Y axes utilize 55 Heavy Duty Roller Linear Guide Rails for smooth, low-friction movement, while the Z-axis employs a hard rail design to boost rigidity during vertical machining—key for deep cavity or heavy material removal.
Design
The GT-1715’s design prioritizes durability, precision, and adaptability. Its heavy-duty frame, weighing 12.5 T, minimizes vibration and ensures long-term stability, even during extended operation. The integration of roller linear guide rails on X/Y axes balances speed and accuracy, allowing rapid traversal without compromising precision, while the Z-axis hard rail design adds robustness for high-load vertical cuts.
Complemented by 5010 ball screws across all axes, the machine maintains consistent motion accuracy, critical for achieving tight tolerances in mold and component production. The BT50 spindle and 18.5 KW motor system further enhance versatility, enabling seamless transitions between roughing and finishing tasks. This thoughtful design ensures the GT-1715 thrives in demanding industrial environments, delivering reliable performance for both high-volume production and custom, precision-critical projects.
