Tolerance check
igus® manufacturing standards
Plastic-compatible tolerancing of CNC components
Plastic has its own characteristic behaviour, which must be taken into account during machining. Our production standards ensure that your turned and milled parts are machined to the correct plastic tolerances.
We recommend adhering to the following standards (see diagram on the right) so that your components can be manufactured as quickly as possible.
General tolerances and special tolerances (length dimensions)
Plastic-compatible tolerancing of CNC components
For length dimensions, the general tolerances in accordance with ISO 2768 (degree "medium") are recommended, as shown in the table on the left.
Tighter tolerances deviating from this are possible up to a certain ISO tolerance level. The minimum possible and recommended tolerances can be seen in the table on the right. (Even tighter tolerances would be feasible on the machine side, but would not be stable over time for plastic components and would therefore not make technical sense).
Design guide
Our free white paper helps you with the key principles for designing your machined components.We give you 12 helpful tips for your machined parts - so you can achieve a design that is optimised for economy and production.

When and why CNC machining is worthwhile for your components
Large variety of materials and material quality:
The large material variety of our iglidur®® -bar stock guarantees you optimum tribological component properties for every application.
High surface quality:
Due to the process, CNC machining produces good surfaces - iglidur® components do not normally require any special post-processing for their sliding surfaces either.
Precise component dimensions with tight tolerances:
You receive dimensionally accurate components with tight tolerances and fits. Narrow tolerance widths (up to tolerance grade 9 in accordance with DIN ISO 286) are usually feasible. Tolerance widths of 0.05 mm are therefore no problem.
Economical for small to medium quantities:
CNC machining is often the most economical process for two to four-digit quantities, especially for large-volume parts with simple geometries.
