Need A Quote- Small (1 sqr inch) 6061 Alu parts, Hardcoat anodized

[KevinWilkins]

I need 500 pieces of these small spacers made from 6061 Alu.

There are:
3 through threads UNC 2-56
1 through hole 4.5mm diameter with light chamfer both sides
2 through holes 2.5mm diameter

2 through holes 3mm diameter are designed for fixturing IF NEEDED, if not needed for fixturing, both may be eliminated

All holes may be drilled, they do not have tight size tolerances, position of the holes must be retained.

Parts should be tumble polished after machining to break the sharp edges and clean up the surface then HARDCOAT anodized black. Care must be taked during anodizing to not damage the 2-56 threads.

Part thickness is 6mm, +0/-0.05mm
Outer contour should not be oversize, it can be up to minus 0,07mm

The PDF drawing is for a price quote, I will supply a final drawing for production as either a DXF/DWG or Solidworks 2009 drawing as desired.

Questions? Please email me: kevin@wilkins.de
I can't pay a fortune for these but this is a good job for a small VMC. I just don't have the time to make these myself right now.

Payment via CreditCard or Paypal

Thanks for looking!

Here's another small part I need, very similar to the first one.

Material: 6061 Alu, hardcoat black anodized
Quantity: 500 pieces

These are pretty easy, the holes can be drilled, there are no tolerance problems there, the thickness needs to be within the specified tolerances which should also be easy enough.

Kevin, what is the smallest radius in the profile of the second part? Is this a one time order? Do you have a delivery date in mind for both parts? If the parts are completely deburred on the machine, do you still require a tumbled finish before anodizing?

Sorry about the missing dimensions, I've posted a revised PDF below with all radius info.

I'd like to get these around the end of Feb.

300 of each would also do me.

This could be a job that comes back, last time I made the 2nd spacer I made a bunch and they lasted about 6 months. However, I don't want to make any promises, the way things are these days...

If the parts are deburred then a tumble finish won't be needed.

It is no problem for me to have all the parts Hardcoat anodized, so anybody can feel free to quote un-anodized too.

All holes can be drilled using a drill bit, no reaming to size is needed. The location will requires spotting or whatever to LOCATE the position, that's important. For the size, if it's a 2.5mm hole, use a 2.5mm drill bit, that will fine.

What can't walk all over the place is the thickness of the parts, as these are spacers! The outer contour has more tolerance latitude.

I usually use AlMgSi1 (6082 T6) Alu for these parts I thought 6061 would be easier to find in the USA, but 6082 is also fine by me.

Hi KevinWilkins

The thickness tolerance of .05mm/.0019 is this after anodizing or before, because the anodizing will make the part grow that much for hard coat

[KevinWilkins]

That would be after anodizing but it really doent matter that much as I will make the other parts of the project AFTER the spacers are done. That way if the spacers are a even 0.1mm thicker I can adjust the other parts to fit.

The main thing about the first part is that the thickness remains pretty constant and doesnt run all over the place, as that is what will really give me fits.

Thank you!.

I really hope folks get too caught up on the tolerances here. They are really more flexible than it may first seem.

I very much appreciate everyone's time and efforts on putting together quotes. Let's keep this open until the middle of next week (27-28 Jan.).

Anyone interested in quoting, please try and get me something by then. I'll take a look at everything and then get back to everyone one way or another.

Please feel free to quote without anodizing as I can easily have that done here.

[KevinWilkins]

Thank for all the interest and quotes on this Project. I appreciate everyone's time and effort.

Anyone still wanting to send in a quote, please get in to me by Wed. morning, 8:00 AM, 27th Jan, Central European time. Quotes coming in after that time will not be considered.

I want to get this job out to the winning bidder this week.

I will contact everyone who quotes individually per email.

Again, many thanks to everyone who has shown an interest, I have been very surprised with how many professional replies this post has generated. I'm cutting a prototype of the first spacer today to check fit and to have a few samples to send the winner, the second spacer is a repeat, so samples are ready to fly on that one already.
