Minimized deformation under load, high precision and a reliable quick-response locking mechanism (suitable in particular for high-strength wires) are features of the newly developed NT straightening units. The roll diameter and the distance between straightening rolls have been optimized in order to be able to straighten process materials that have a wide range of diameter sizes.
The mechanical heart of a NT straightening unit is its precision base and is built in the German tradition of high quality. It accommodates the elements needed for roll positioning, the components of the quick-action locking device with a transparent protective cover. The locking handle of the quick-action locking device is designed with a telescoping handle, allowing maximum locking force to be applied when desired. Positive-fit levers on the locking handle keep the straightener reliably closed during the straightening process.
Depending on the specific wire size range the NT 7-2.0, the NT 7-4.0 or the NT 7-6.0 unit should be used for the straightening processes. This straightener suits a wide variety of applications and is available in single, double or more planes with an easily added connection base. The NT model has the all roller adjustability for the best straightening results and maximum flexability.
This is most commonly used in wire applications but also can be used for tubing, cable and other materials. We use the highest quality roller bearings and vee grooves are standard, but other profiles are available on customer request. We offer a number of roll type possibilities for specific applications to tailor to unique demands including sleeved roll with outer rings in different materials like stainless steel, PET plastic and hardened steel. There are many options available and one of the more valued is the digital roller position indicators that substantially reduce set up time.
