10～5000N.m Torsion Testing Machine
Maximum Test Force: 10～5000N.m
- Description
The NJW series torsion testing machine is composed of a loading system, a transmission system, a digital data acquisition and processing system, and a computer measurement control display system. It is suitable for static mechanical performance testing of various components such as transmission shafts, half shafts, etc. Test on the torsional mechanical properties of screws. The machine adopts horizontal structure.
Computer screen display, digital data acquisition control system and fully digital AC servo system form a closed-loop control. It adopts precision reducer transmission and has the characteristics of uniform loading, stability, no impact phenomenon, and accurate data acquisition and control.
1.What about the production time?
The production time varies for different products. If the product is in stock, the delivery time is within 5 days. For standard products that are not in stock, the production time is 15 days. The more customization a product requires, the longer the production time, with a maximum of 3 months.
2.Can you provide the related documents?
Of course. Regarding certificates, we can provide ISO, CE, and other certificates as needed, or any other documents you require, and we can provide them promptly. As for the product manuals, you can download them from the corresponding section on our website, or you can leave us a message or contact us through WhatsApp, Facebook, LinkedIn, etc.
3.Can you guarantee safe and secure shipping of products?
Our products always use safe and high quality export packing. We use high-quality wood packaging, and we also have long-term partnerships with freight shipping companies. Of course, you are welcome to specify your preferred shipping company.

Features
This machine is controlled by a computer, and the transmission system is controlled by a transmission loading servo system. It adopts a precision torque sensor, which has high measurement accuracy and good stability. The computer automatically displays test data such as torque, torque coefficient, torsion angle, loading rate, and test torque peak, and displays Test twist angle-torque, torque-time, twist angle-time curves; store and print test reports. (The ultimate torque, effective torque, torque coefficient, and torsion angle can be found.)
