Tolerance classes iaw. ISO 22081 and DIN ISO 2768: Optimized use of general tolerances

Tolerances are an essential aspect for manufacturing mechanically moving parts, as they ensure the correct interaction of components. General tolerances and their tolerance classes are used to simplify drawings. The standard DIN ISO 2768 specifies tolerances. Many design engineers use general tolerances as a simplified variation of tolerances to facilitate the design process.

Low-reflective surfaces – LTBC and other options

Reflective surfaces can cause malfunctions in certain applications and even influence the results, e.g. in quality control or dimensional inspections. This should be taken into account when selecting a surface. But how can reflections be minimized? This article presents various options for surface treatment and surface coating. Low Temperature Black Chrome Plating, LTBC or also black chrome process, is explained in particular.

How to select the right component surface – Basic knowledge about surface roughness

Surface roughness and surface hardness are important properties that must be considered when selecting components. Although there are various methods to measure roughness or surface roughness of the surface of a component. However, these measurements often have to be converted to a standard dimension.

Principles of Dimensional Tolerances and Fit Selection

Dimensional tolerances play a decisive role in mechanical design and directly influence the functionality and quality of machines, devices and other mechanical products. In mechanical design, tolerances refer to the permitted deviations from the ideal dimensions of a component or an assembly group. There are different fitting systems, such as the standard bore and standard shaft. For more information on tolerance classes, see our blog article “Tolerance Classes According to ISO 22081 and DIN ISO 2768”.
