Din 6930 M Tolerance Pdf
General tolerances for parts made by fine blanking (see VDI 2906 Part 5) are not covered by this standard. If, as an exception, this standard is also applied to parts made from semi-finished products other than flat products, or from materials other than steel, this shall be agreed separately. This standard is to be applied in conjunction with DIN 6932 on design rules for stamped steel parts.

It specifies general tolerances on linear and angular dimensions and on coaxiality and symmetry in four accuracy grades which are meant for use and hot stampings made from steel flat products.

One of the external shafts has a f9 while most of the other shafts have a h9 or h6. A keyway has a N9 and the internal keyway has a j59. One of the internal bores has a M6. Most of the tolerances use lower case but some are upper case, I dont know if that makes a difference or not. Anyone know of a source for a simpler explaination of these that is in english? Machtool, Yes I got that too, but there are a lot of other tolerances that are not listed in my handbook.
I have some drawings from Germany that use the DIN 2768 tolerances and I am having trouble understanding it correctly. I do not have a full copy of the DIN but I do have some notes and a brief discription of how the tolerances are supposed to work but I still dont quite understand it. The parts are shafts and couplings and have to fit bearings so I know some of the tolerances are going to be plus and some are minus. Could anyone offer a simpler explaination of what I am seeing.

Even if it was in German I could work with the tables or have one or two locals translate for me. Thanks to all Charles.

I just need to find a better source and I am hoping to not have to buy all the standards if I dont have too. I am just quoting the job and I am still waiting on some answers from the company I got the drawings from. I thought I could get a head start and educate myself at the same time. One shaft has a dim 25mm f9, a bore is marked M6 and to me that seems super tight, more than the part requires but I am hoping I just read the chart wrong. There are keyways and snap ring grooves and I just cant seem to find all the information I was hoping for in the MHB but I will keep searching. Charles, you have some weird tolerances on there, those are very rare for bearing fits.
The +43 on the h9 tolerance is definitely wrong, all the h tolerances are +0 and a negative number. Are you sure you are not looking at H tolerance tables? The capital H is for holes and all of those are 0 to a plus number. After you have used it a bit, these tolerances get easier. I wish I had a copy of the complete tables I could email you, the following link is mounting and dismounting catalog that has tables in the back, but does not have all of what you are looking for. If I find some time tomorrow, I will see if I can scan my tables and send them to you.
Regulations for general tolerance in existing drawings are included in clause 5.*This standard is the technical revision of the standard which has been published in 2010-01. This revision primarily includes the update of the normative references and the expansion of the nominal dimension ranges and the tolerances for thickness ranges or for angles on flat stamped parts. This standard is intended to simplify drawings and specifies general tolerances for linear and angular dimensions, concentricity and symmetry in four accuracy levels. They are subdivided into f (fine), m (medium), g (coarse) and sg (very coarse).

Thank you, I just found the tolerances on the keyway, and no the M6 is on a 47mm bore which makes me wonder why so tight a tolerance, I was hoping I was reading it wrong. I didnt see where you got the -17 from, at least that would allow me to have a little more room to work. D-link dsl 500g firmware upgrade. On the 12mm my MHB must have a typo because it says the tolerance is +43 -0? I didnt think that correct for a shaft but that is what is in my book. Now you know why I wanted to ask others, this doesnt really add up. I really do need some reference that I can point to for these just in case there is any problem I need some printed version of these tolerances.

This standard is intended to simplify drawings. It specifies general tolerances on linear and angular dimensions, and on coaxiality and symmetry with four tolerance classes as follows: f (fine), m (medium), g (coarse) and sg (very coarse). By selecting a specific tolerance class, the customary workshop accuracy is taken into consideration.

I have an ISO Tolerance book my company published, but it looks like it is not available any longer. 12mm h9 +0 / -43 25mm f9 -20 / -72 10mm h6 +0 / -9 Is the M6 hole tolerance also 25mm? If so, it would be -4 / -17 By the way, DIN 2768mk is a general tolerance table that provides the tolerances for anything that is not toleranced on the drawing, it does not refer to the diameter tolerances you are asking about. You can find info on the DIN 2768 at the link below.
Thank you all for your help, this has been quite an education so far but it does seem to follow a pattern and I am glad I have decided to follow up with it. Your help at least lets me know where I was right and where I need to work a little harder. If anyone knows of a techical reference that might be more inclusive and useful I will gladly pay a little for the effort to copy and email or mail it to me. I was thinking of a Text book?
