Tolerance check

You will receive direct feedback as to whether the requirements of the machined parts on your drawing are feasible or whether something needs to be adjusted.

It's really easy:

1. Upload technical drawing (.pdf, .jpg or .png)2. Receive analysis results and suggested changes3. Simply download the corrected drawing and/or request support from our team

Tolerances of CNC components that work with plastics

Plastic has its own characteristic behaviour, which must be taken into account during machining. Our manufacturing 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 produced as quickly as possible.

General and special tolerances (lengths)

Tolerances of CNC components that work with plastics

For lengths, the general tolerances according to 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 found in the table on the right (even tighter tolerances would be feasible on the part of the machine, but it would not be possible to maintain them with plastic components over time, which would make no sense from a technical point of view).

When and why CNC machining is worthwhile for your components​

Large variety of materials and material quality:

Bar stock

The large material variety of our iglidur® bar stock guarantees you optimum tribological component properties for every application.

High surface quality:

Processing

Due to the process, CNC machining produces good surfaces - iglidur® components normally do not require any special post-processing for their sliding surfaces either.

Precise component dimensions with tight tolerances:

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 0.05mm are therefore no problem.

Economical for small to medium quantities:

Special parts

CNC machining is often the most economical process for two to four-digit quantities, especially for large-volume parts with simple geometries.
