HANI Introduces TK6513A CNC Boring Machine to Enhance Production Equipment Strength
Publicado el: Junio 2024 | Industria: Heavy Machinery & Steel Processing
In a strategic move to strengthen its manufacturing capabilities, HANI has officially brought the TK6513A CNC boring machine into full operation. This advanced piece of equipment is specifically designed for heavy-duty machining tasks commonly found in the production of rolling mill machinery and steel rolling mill components. With increasing demand for precision-engineered parts in metallurgy, mining, and industrial transmission systems, investing in high-performance boring machines like the TK6513A ensures better control over quality, delivery timelines, and long-term cost efficiency.
Why the TK6513A Matters for Rolling Mill Equipment Manufacturing
Rolling mill machinery operates under extreme conditions—high pressure, continuous load, and constant vibration. The core components such as gearboxes, housings, bearing seats, and frame structures require extremely precise bore alignment and surface finish. Even minor deviations can lead to premature wear or catastrophic failure during operation.
Traditional machining methods often fall short when dealing with large-scale parts used in steel rolling mills. Many manufacturers still rely on outsourcing these critical processes, which introduces delays, inconsistent quality, and higher logistics costs. By integrating the TK6513A into their workshop, HANI now maintains full in-house control over one of the most technically demanding stages of rolling mill equipment fabrication.
Key Features of the TK6513A CNC Boring Machine
The TK6513A is manufactured by Shenyang Machine Tool (Group) Co., Limitado., one of China’s leading producers of heavy-duty CNC machine tools. It belongs to the category of horizontal milling and boring machines with table travel design, making it ideal for processing large box-type workpieces such as gearbox casings, soportes de molino, and foundation plates used in steel rolling lines.

Aplicación en el mundo real: Machining Large Gearbox Housings for Steel Rolling Mills
One of the primary applications of the TK6513A at HANI is the precision machining of large gearbox housings used in hot and cold rolling mill lines. These housings typically weigh between 8,000 a 15,000 kg and require multiple precision bores ranging from Ø200 mm up to Ø800 mm, with tight tolerances on concentricity (<0.03 mm) and parallelism.
Before acquiring this machine, HANI had to outsource these operations to third-party workshops, which led to extended lead times—often exceeding 6–8 weeks—and limited flexibility in scheduling. Ahora, with the TK6513A running in-house, they can complete a full set of boring, molienda, and facing operations within 7–10 days, including setup and inspection.
This improvement directly supports faster turnaround for complete rolling mill equipment packages, especially for turnkey projects involving reconditioned or newly built tandem rolling stands.
How the TK6513A Improves Precision in Rolling Mill Component Fabrication
Precision is non-negotiable in rolling mill machinery. Misaligned bores in a mill housing can cause uneven roll gap distribution, leading to poor strip thickness control, increased roll wear, and unplanned downtime. The TK6513A addresses these challenges through several key engineering features:
- High Rigidity Structure: The machine uses a robust Meehanite cast iron bed with optimized ribbing design, ensuring minimal deformation even under heavy cutting loads.
- Dual Column Support + Crossbeam Guidance: Provides excellent stability during deep boring operations, reducing tool deflection and improving hole straightness.
- Automatic Tool Changer (ATC): Equipped with a 24-station tool magazine, allowing uninterrupted switching between face milling cutters, boring heads, and drilling tools.
- Laser Interferometer Calibration: After installation, the linear axes were calibrated using laser measurement systems to ensure micron-level accuracy across the entire travel range.
- Coolant Through Spindle Option: Delivers high-pressure coolant directly to the cutting edge, enhancing chip removal and extending tool life—especially important when machining alloy steels and nodular cast iron.

Tips for Maximizing Utilization of CNC Boring Machines in Rolling Mill Projects
Getting the most out of a machine like the TK6513A requires more than just proper installation—it demands smart planning and workflow integration. Here are some real-world tips that HANI has adopted since bringing the machine online:
- Batch Similar Workpieces: Group machining jobs by material type and size. Por ejemplo, process all large cast iron gearbox cases in one production run to minimize tool changes and setup time.
- Use Pre-Machined Blanks: Ensure rough casting or forging blanks come pre-machined (face milled and drilled for clamping) so the TK6513A can jump straight into precision boring without extra alignment steps.
- Invest in High-Quality Boring Bars: Standard bars may flex during deep-hole boring (>5xD). Use carbide-reinforced or anti-vibration damping bars for bores deeper than 400 mm.
- Monitor Thermal Drift: Run warm-up cycles before starting precision jobs. Ambient temperature shifts can affect spindle alignment by up to 0.02 mm over an 8-hour shift.
- Train Operators on G-Code Optimization: Simple tweaks like adjusting feed rates during entry/exit phases can reduce tool chipping and improve surface finish on hard materials like 42CrMo4.
Long-Term Benefits for Rolling Mill Equipment Manufacturers
Bringing high-capacity CNC boring capability in-house isn’t just about faster cycle times—it transforms how companies approach project quoting, quality assurance, and customer service.
Por ejemplo, HANI can now offer guaranteed bore concentricity reports with every mill stand assembly, backed by actual CMM (Coordinate Measuring Machine) data taken post-machining. This level of traceability is increasingly required by international clients in Europe and Southeast Asia, particularly for replacement parts in aging rolling lines.
Además, having full control over the machining stage allows for quicker prototyping and design validation. When engineers propose modifications to a housing layout—such as relocating oil passages or adding lifting points—the team can test the feasibility within days instead of waiting weeks for external feedback.
Mirando hacia el futuro: Integration with Smart Factory Systems
The TK6513A comes equipped with digital interface options that support integration into modern shop floor monitoring systems. HANI plans to implement real-time data collection from the machine’s CNC unit, tracking metrics such as spindle load, tool usage hours, program execution status, and alarm history.
This will enable predictive maintenance scheduling—knowing when a spindle bearing might need servicing before it fails—and allow production managers to monitor utilization rates across shifts. In the future, this data could feed into ERP systems for accurate job costing and resource planning.
As global competition intensifies in the rolling mill machinery sector, manufacturers who combine strong mechanical foundations with smart digital practices will hold a clear advantage. The addition of the TK6513A is not just a capital investment—it’s a step toward building a next-generation heavy machining facility capable of delivering world-class steel rolling mill equipment with confidence.
