We don't start with blueprints; we start with problems on the front line.
Rather than chasing flashy features, TN Nakazawa’s R&D process focuses entirely on the details that impact operational efficiency, the designs that could inflate maintenance costs, and the variables that dictate the stability of test results.
Our R&D Process:
- Problem Observation & User Need Gathering
- Mechanical Design & Control System Development
- Prototype Development & On-Site Simulation Testing
- Continuous Optimization & Multi-Round Adjustment
- Market Launch & Upgrade Support
We never ask users to adapt to our equipment; instead, we proactively learn how they work. Equipment design should "assist" rather than "disrupt" the workflow. This is the R&D logic of TN Nakazawa: starting from the field, and delivering results back to the field.
Equipment is not born on a desk; it is proven through rigorous testing on the production line.
All TN Nakazawa equipment is manufactured in-house at our facility in Central Taiwan, encompassing every stage of machining, assembly, testing, and final inspection.
Modular manufacturing design simplifies maintenance and upgrades.
Full autonomy over production workflows ensures complete traceability of equipment histories.
Unified assembly and testing processes enable seamless, cross-departmental collaboration.
Pre-shipment live equipment testing and high-intensity simulated run-in operations.
We don't just build equipment; we create a trusted metallographic sample preparation system.



Not just modification, but redesign based on your application.
TN Nakazawa’s customization capabilities include:
Specialized sample fixtures / cutting methods / cooling systems / automated feeding
