So I cut Inconel and Stainless Steel on a 400 watt CO2 laser, typically between 0.007 - 0.015in thick so sheet metal. I use Simple Green Anti-spatter and it seems to work good for Stainless Steel but on Inconel of the same thickness I tend to get a very small amount of spatter adhering to the...

I would use the +/- tolerances given and transfer them into profile tolerances for each feature segment. Radii are very difficult to inspect for and should, when possible, use profile tolerances to show that the feature edges are within the tolerance zone and not focus on the inspected radii values.

The information says ISO 6150/B. But I think thats just the quick disconnect profile.

Right so BSPP is straight parallel threads and BSPT are tapered threads. From this coupling that I got they are indeed straight parallel threads which according to the definition will require this ring/washer. So they are not BSPT. Is there 2 different versions of BSPP with one that does not...

So I have these fittings that are said to be G1/4 threads which are BSPP straight threads. The original female fittings inside have a copper crush washer that bottom out on a flat backing that seal against the male and female connections. I bought new female fittings to replace them that are...

Thanks for the reply guys

Looking at brass quick disconnect fittings for fluids and compressed gas. I'm looking for information about using these fittings that are labeled as for "Air" use but use them for water. Is that generally not a good idea? I'm not able to find any information that specifically says no. The quick...

The drawings invoke Y14.5-1994, the older ones possibly 1982 still. Usually the companies do state their own internal drawing interpretation spec. Ill have a look at some of those.

Sometimes we get auditors in here saying they can't pass our parts since we restrain them when we inspect them when the drawing doesnt state that we can. So basically that would scrap every part made. The problem is that getting a drawing change costs companies months and thousands of dollars...

So I have inherited a few problems with a company I work for. All of the parts that we manufacture are thin sheet metal that can bend with even a 1 lb weight on them, they bend and deform in assembly that is their intent. The problem is that these parts have been manufactured since the 1970s and...

Thanks guys, your comments have been helpful.

Whats the difference in the feature control frame of a composite tolerance vs multiple single segment tolerances? I got this on a drawing and these 2 flatness tolerances are considered Datum A. To me the bottom example feels like it was a mistake by the drafter as most of the drawings that came...

Id love to freely just get you guys pictures but because these are aerospace parts theres rules about which parts can be shown and which cant so until I can get that information we'll just have to make due.

Hi all, I have parts being Nickel plated to AMS 2424 about 0.002-0.004 thick and being shipped over seas from the UK to the US. They have a post plating heat treatment thats at something like 900F (500C) for an hour. Typically theres a good amount of my parts that have a blue blotchy stain on...

Ok Ill look into doing that. thanks :)

I would think that with sand paper that taking off a few thousands of material is quite difficult if using a higher grit while using a file or cutter you could accidentally take off a chunk of material easily if you're not paying attention.

The hardness is probably on the softer side maybe low 50s HRC. Im just concerned with changing the shape by turning the roller with anything hard like a file or cutter.

These rollers are precisely shaped rollers and removing even a few thousands can change the dimensions of the part that it forms so I don't know if I should go through with grinding/turning it. I can put the roller on a lathe to spin it and assist with the hand sanding.

I have some sheet metal rollers that are D-2 and hardened. These rollers are probably at least 20 years old and are in need of some maintenance. They are pitted and have scratches. What would you guys recommend for polishing hardened rollers? Would I have to get some kind of compound or would...

Yes in this fixture the force will be mostly one direction, the opposite direction will probably just be a return.
