Not a robot in sight. I read about the M-1 Garand receiver having 40 separate milling operations, Remington must have been doing it the same old inaccurate way.
I’d ask Vita needle to do the job. I’ve had them do custom work, great outfit to deal with.
I think you could also get through the job with a royal master center less grinder. Hypodermic points are simply ground in a few passes.
Study how composite boats are built, foam core sandwich and tabbing.
Use the carbon’s strength to your advantage and mold parts that move the load path away from your joints.
Also to note, normal west systems resin is too brittle for secondary bonds. You’ll want to use a rubber toughened epoxy.
The wood shop at 2:37 is cool, the axe on the floor did most of the roughing work. It looks like they are making a wing rib and to the left it looks like a prop is getting re-glued.
At 4:00 you can see a compass plane that looks like it was shaping a landing skid. landing skids and struts were...
I don’t think the OP talked about buying ten machining centers nor scaling so he could expand. It sounds like he wants an after hours gig to make some extra cash.
We have all read the threads about the guy who wants to put a machining center in his garage to make parts for extra income. What...
A-36 replaced 1020 as a common grade run of the mill steel. Before steel recycling became widespread 1020 was very common
1020 is not that uncommon in plate, Alro had the 10" plate we needed. Round bar is out there.
Just a thought- if you spent the 15 k on Mastercam and 5k on a computer and can bill $100-150 an hour, you will be light years ahead in profit margin then the person that owns the spindle.
I perform the same inspection task you are talking about often. I use three 2” long square gauge blocks. I will move the blocks around under the part to find the average deviation.
I used eBay as a source for the blocks.
Look into Mitsui Seki, or Yasda. I spoke with a Yasda sales guy that mentioned they were milling to a few microns on silicon mold shut off's all day. They did have in machine probing so it was a closed loop system. You could probably do it on a lesser machine with glass scales and develop a...
I spoke with Ohio broach and the part was not a good fit for broaching. They were helpful and did a few calculations to determine the required root cross section would be too weak for the amount of material to be removed.
Bourn and Koch dumped wheelbarrow loads of an epoxy granite mix in the cast iron base of a new machine they were building. It was a special vibration dampening formulation and was only added in specific pockets of the casting.
You should be able to find the resin and filler. Also look for...
My two cents on operators and small insert screws.
Get your operators a torque screw driver and use the proper torque on the insert screws. Place a sticker with the recommended torque on the box of inserts. Swap the lid when you get a new pack so you don't need to make a new label. Most over...
Face plates with clamps seems like a lot of messing around, and you still have un even pressure. I would turn a fixture with a 6" od with a tapped hole in the middle and hold the part on with a disk. Skim the od while your clamping forces are small and even on the OD. It will be within tenths...
