Shuochao CNC TX75300 Double Gantry CNC Boring Milling Machine Delivered and Commissioned for Deyang Customer to Boost Large Workpiece Machining Efficiency
2026-05-19
Recently, the TX75300 double gantry CNC boring and milling machine independently developed and manufactured by Shuochao CNC has finished installation and commissioning, and been officially delivered to a customer in Deyang for mass production. The machine is designed for integrated boring, milling and drilling of large steel structures, energy equipment, heavy machinery and extra-long workpieces, delivering robust equipment support for customers to upgrade their large equipment manufacturing capacity.
The delivered TX75300 CNC gantry boring milling machine adopts a synchronous double gantry driving system equipped with a box-in-box ram structure with sufficient rigidity. It features an ultra-large machining travel of 30m on X-axis and 7.5m on Y-axis, supporting continuous multi-process machining of large and oversize workpieces in a single clamping setup. At present, the machine runs smoothly with all performance indicators meeting design expectations and has been fully integrated into the customer’s production line.
Ultra-Long Travel Meets Machining Demands of Oversize Workpieces
Driven by the growth of energy equipment, heavy machinery, bridge steel structure and large engineering equipment industries, machining of extra-large workpieces raises higher requirements on machine working range, load capacity and machining consistency.
With an expansive machining envelope, the TX75300 CNC gantry boring milling machine is widely applied to process the following parts:
- Large steel box girders
- Large structural components for wind power equipment
- Oversized parts of construction machinery
- Parts for shipbuilding and offshore engineering equipment
- Heavy machinery frames
- Energy equipment and pressure vessel components
The machine supports multiple machining procedures including surface milling, boring, drilling and tapping. It completes all complex machining steps in one clamping, effectively lifting production efficiency and finished part quality.
Double Gantry Structure Improves Machining Stability for Large Components
To satisfy the machining requirements of extra-long travel, the TX75300 CNC boring milling machine is equipped with synchronous double gantry driving structure, maintaining steady motion precision and smooth running performance during full-stroke operation.
Core advantages of double gantry layout:
- Improved overall machine rigidity and load capacity
- Consistent motion precision across full travel range
- Enhanced stability when machining large workpieces
- Suitable for heavy-duty continuous cutting
- Meets long-term production demands of heavy equipment manufacturers
Thanks to well-optimized structural design, the machine maintains excellent dynamic performance during processing large workpieces and provides steady machining support for users.
Box-in-Box Ram Enables Heavy-Duty Milling
The TX75300 CNC gantry boring milling machine features a self-optimized Box-in-Box ram structure developed by Shuochao CNC.
Compared with conventional ram designs, the box-in-box structure greatly boosts overall ram rigidity, suppresses vibration under heavy cutting loads, and stabilizes machining precision and surface finish.
Key strengths of Box-in-Box ram:
- Ram structure with sufficient rigidity
- Excellent vibration resistance
- Capable of sustaining heavy cutting loads
- Stable precision during long-hour non-stop operation
- Extended service life of the whole machine
This structure is especially suitable for large component processing in steel structure, heavy machinery and energy equipment industries.
Multiple Processes Completed in Single Clamping
Benefiting from the 30m X-axis travel and 7.5m Y-axis travel, the TX75300 CNC gantry boring milling machine realizes full processing of extra-long workpieces with only one clamping operation. It avoids repeated positioning errors and raises overall machining efficiency.
Available machining processes:
- Surface milling
- Boring
- Drilling
- Hole pattern machining
- Tapping
- Complex contour machining
When processing large steel box girders, heavy frames, machine castings and extra-long welded structures, the machine drastically cuts auxiliary working hours and improves consistency of finished products.
