CORDAS

Product catalog summary

Specifications and Variants
The document outlines two main variants of the CORDAS length measuring instrument: the fixed setting piece and the adjustable setting piece. The fixed setting piece (9630.xxxx) is designed with a lightweight carbon-fiber structure, insensitive to thermal influences, and uses gauge blocks for setting devices like the CORDAMETER 4630 CFK. It supports a measurement range of Ø255 - Ø1500. The adjustable setting piece (CORDAS 9740) is suitable for VARICORD 4730 CFK, offering variable length adjustment and similar thermal insensitivity and lightweight design.

Setting Procedures
The document describes the setting procedures for both fixed and adjustable masters. For the CORDAMETER and CORDAS, the setting involves adjusting the fixed dimension considering the measuring position. The fixed master requires setting the angle and height, while the adjustable master involves presetting, clamping on a flat surface, and using a CMM or bench to take the set length.

Options for Setting
Various options for setting Kordt length measuring instruments are discussed. These include using a length measuring bench for high accuracy and flexible use, fixed setting masters for high accuracy in measurement orientation, and adjustable setting assistance for flexible use over the instrument's range. Each method has its advantages and limitations, such as the need for additional measuring devices or limited access.

Temperature Compensation
The document references a publication on temperature influence during the measurement of large workpieces, emphasizing the importance of observing the temperature of the test piece to account for thermal expansion.
