Among the most important classical design elements are springs, in which the elastic properties of materials are exploited for energy storage and conversion. Without springs—regardless of their design—no mechanical or electro-mechanical system would operate. The main functions of engineering springs are
Zwick offers special solutions for the most varied spring systems.
Rapid technical advance has led to a significant increase in the demands placed on the accuracy and durability of springs. The corollary of this is greater demands on manufacturing accuracy due to ever-smaller dimensional, form, and positional tolerances, with similarly enhanced requirements for testing technology.
The PrecisionLine series easily meets the increasing demands placed on state-of-the-art precision spring testing machines, where the highest level of accuracy and repeatability is called for. It was developed for the testing of springs with very low tolerances, such as those used in many mechatronic assemblies and function units in the automotive industry. The series design takes all error influences into account.
The zwickiLine (single-column testing machine) with testControl electronics, together with the precision spring compression test kit, is ideally suited for use as a precision spring testing machine. The kit is extremely transverse force-resistant and protects against overload. The ground, demagnetized compression platens have a parallel alignment of 1 µm/10 mm and precision guides permit only precise vertical movement of the compression platens. Measuring errors caused by deformation or lateral forces of the springs are reduced to a minimum thanks to the extremely stiff load cell, which is resistant to transverse forces.
