ISO 2768 fine or medium?

0
L
1

Hi, I’m trying to decide between ISO 2768 Fine and Medium tolerances for CNC machined aluminium parts. What are the practical implications of this choice in terms of achievable precision, manufacturing cost, and lead time? The CNC-machined parts will be used in the main structural components and linear guide rails (we’re talking about a small-scale automated assembly line for electronic components). I need high accuracy for component placement (withing 0.1mm), but I’m concerned about potential over-engineering and unnecessary costs. Thanks in advance for your help!

Hello Korhonen,

You can visit this article to know everything about ISO2768 standard and what tolerances will you achieve by choosing medium or fine standard.  https://xometry.pro/en-eu/articles/standard-tolerances-manufacturing/

Choosing fine tolerance you will get a better precision (within 0.1mm on dimensions up to 30mm), but the part will have higher cost and higher lead time, due to the need to have slower cutting speeds and more precise tooling.

Depending on the size of your part, Medium tolerance can be enough, or you may need to use Fine tolerance to achieve the required results.
