aluminum

Hi. In previous visits I've gotten remarkably good advice on some tricky (for me!) problems, and I've some back to the well, so to speak. I've got an assembly in which an inner cylindrical piece (diameter 40mm, or about 1.6") of anodized aluminum revolves inside an outer collar, with a couple...

This started without plans. Then I realized I better get some set up. I can't just wing it like others. I had an idea in my head to use this chunk of Aluminum, after cutting it, is when I realized that I need some idea of sizes of things.. Probably it would have been better to start that way. I...

First let me start by saying I'm new to this and fumbling my way around. I have some 6061T6 bar stock and I'm trying to get a good finish on it with carbide inserts. I'm not sure where to start with spindle speed, power feed rates and insert selection. I have tried various spindle speeds from...

The clamp is 1 inch wide by 1/4 in thick by 14 inches in diameter. It is in two halves hinged together. The closing mechanism is tangs or fingers with a 1/4 x 20 thread closing mechanism. The break is half between the hinge and the closing mechansim where the telescope is intended to be mounted...

I found a lot of variations of these holders and went with the easiest one for my first attempt. I would like to make another variation when I get some more steel. It will work for now.

I am trying to tap 1/2 inch deep 10-32 holes in T6061. The holes are drilled with a #21 drill and I am attempting to tap the first one. The tap is aligned well. The tapping was strange compared to steel from the beginning. The steel technique is to tap forward until build up is felt then to...

I picked up a milling attachment for my 7x10 HF lathe, and now I need to do something with it... My first project is going to be some light-duty 6061 aluminum tool holders for mounting indicators and whatnot. So, now I need a dovetail cutter and some end mills. Is there anything in particular...

Hello Machinists, I just purchased a Taig about five months ago, and am entirely self taught (using what I could find on the internet). I am cutting small molds out of 6061 aluminum. What is the optimum RPM, IPM, and DOC for a optimum surface finish using a carbide facemill? I understand...

Hello, I am northeast GA. (North West Gwinnett county) and need to get a quote on the following; I have the following aluminum that needs to be turned and welded; 1 - Aluminum tube 5" I.D. x 24" Length x 3/8" wall. 2 - 5" O.D. Diameter x 1/4" thick round plates with 1" bore (already turned...

I have a small, unimportant, aluminum part that I would like to cosmetically protect against being splashed with cutting fluid. The part is in no way critical but I would like to go about this the "right way" as a learning excise. I have no previous experience with finishing aluminum and I am...
