Efficient calibration of measuring equipment - various standards with highest precision

There are various possibilities here: The range extends from Standards for testing specific angles, perpendicularity and length accuracy. For example, a so-called parallel gauge is used for length accuracy. For calibration, these represent the standard with the smallest measurement uncertainties in each case. Alternatively, a gauge block can also be used as a secondary standard for measurement. Furthermore, the product range also includes parallel supports with an accuracy of 5 µm as well as a squareness measuring machine.

The gauge block for length accuracy

This form of the Parallel gauge consists of cuboid blocks of different lengths with a high length accuracy. Due to their equally high surface quality, these can be assembled to the desired lengths. Adhesive forces act on the individual blocks as a result of this pushing. Thus, the length to be calibrated or measured can be assembled as desired. However, it should be noted here that a possible final dimension combination should consist of a minimum of individual blocks, since their dimensional deviations add up in each case

So that the angle is also correct ? the angle gauge block

The counterpart for angular accuracy is the Angle gauge block. These can also be assembled to the desired angle by pushing the surfaces together. Special versions allow a gradation of the angle of up to one second. In addition to calibration, cones, angles or angular divisions can also be measured in a simplified manner. A special form is the angle standard, which is used for fast and precise testing of the 90° angle. In this way, right angles can be easily tested on machine tools or coordinate measuring machines. An angle standard can also be used as a precise contact surface for larger components.

Parallel supports for precise machining of the workpiece

To achieve a high final accuracy, the placement of the workpiece in the machine tool is also essential. For this purpose, in addition to a rip fence, the use of Parallel shims can be used. These supports allow precise adjustment of the workpieces to be machined by means of rapid height adjustment in the machine. The required height can simply be taken from the set of supports and assembled. This reduces not only the clamping time but also the associated unit costs

Quality and durability through the use of high-quality materials - quality according to din en iso 3650

The Normal are manufactured from high-quality materials such as stainless steels, hardened special steels or hard metal. Alternatively, special materials such as granite are used for 90° angle standards. To achieve a high surface quality, the standards are machined using processes such as grinding and lapping. For this reason, all products are manufactured according to the quality class of the din en iso 3650/1 standard. This standard also divides the respective gauge block into different tolerance classes k, 0, 1 and 2.
