It’s always way easier than me think. I have made press dies with Plywood and had amazing success. Good job man.

[@thekraken1173]

Can a 10 ton hobbyist press bend 1mm cheap steel sheets (with 6 cm depth)? Or should I buy a 15 ton press? The shape is not like a square profile, it is more like an oval profile; so corners should not be a problem in my opinion. Sorry if my question lacks any detail, I am a clueless student, any help would be appreciated.

[@frederickvobbe7002]

Good explanation, and demonstration. I was searching for info for pressing steel mesh (Opening 0.097") into microphone grill shells. Thanks for good tutorial.

[@craigsmachineshop2040]

Thanks! Glad it helped

[@Daniel-vq9zb]

Make sure to add some leader pins for alignment on the real one, also some die springs would be nice so you dont have to pry it open every time.

[@craigsmachineshop2040]

I was going to make one with 4 pins but I have a base with 2 pins. I am going to try to make that work. I got some springs but didn't figure on the weight of the upper die pushing the springs down too much. LOL I ordered some new springs that should work. Thanks!

[@Daniel-vq9zb]

@@craigsmachineshop2040 sounds like your headed in the right direction, it really wouldn't matter much for what your doing sense the part is symmetrical, but it's a good idea and a industry standard to have a offset pin so the a and b side of the die cant be turned in any other direction, just a thought for down the road though. If you have any questions hit me up I mainly work in the injection molding industry but do some die work, and many of the same principles apply.

[@craigsmachineshop2040]

Yeah, I see your point. I have just been drilling a small shallow hole in the left front edge of the fixture plates and dies to know how to put them on. LOL I guess I should be more professional about it for when I get employees. Injection molding, wow cool! I appreciate it!

[@anthonyjones657]

So I'm curious if you have a punch going through .050 material making a .125 hole. What should the hole in the die plate be .1255 or ??

[@123tools1]

@@anthonyjones657 Die clearance is 10% of material thickness ,the punch gives you the hole size

[@mykahdeanwilson]

Little tip. Always use the fixed side of the vice to set your zero

[@craigsmachineshop2040]

Thanks, yeah I tend to not worry about it with a non-critical part. I suppose I should for a good habit.

[@revgro]

NIce job. Before watching this video, I would have said that the final result using aluminum wouldn't be usable. You proved me wrong. Good luck on your final tool.

[@craigsmachineshop2040]

Thanks! I wasn't sure either. Due to the success I may make the final dies aluminum with a steel holder.

[@mm-tl5gc]

I've never used a cnc machining centre so not sure if this is relevant, but when milling you want to go in the opposite direction of the cutting tool to prevent "climbing" where the milling cutter runs along the work piece, often resulting in broken cutters. If you've ever experienced this, I hope this helps. Great video by the way.

[@craigsmachineshop2040]

Thanks for the comment. I was always told that you didn't have to worry about conventional milling when machining with a CNC mill so I just went with that. Your comment got me to look deeper into the topic and got a lot of useful information from Tom's Techniques. From my understanding from his video and other videos, climb milling leaves a better surface finish on finish passes since it isn't rubbing when it enters the part and extends tool life for the same reason. It looks like climb milling only becomes a problem when taking larger cuts with a smaller machine, when there is less rigidity in the workholding or when there is backlash with the ball screws. I had no problem taking larger cuts in A2 while climb milling recently, So I am assuming that it is ok with my mill. Maybe it has something to do with the precision ball screws or the fact that it is controlled by stepper motors. I will probably go with servos on my next mill since they keep track of where the table/head are. My Tormach with steppers can lose steps so I have to be careful not to be too aggressive. Thanks!

[@evanorner4979]

We are trying to manufacture the Piper Airplane Ashtrays in our haas Cnc and we are having a hard time with the programming

[@gwheyduke]

That worked nicely. I've made a couple of homemade round dies for the ends of a model engine fuel tank and the ends of a small steam boiler. Also experimenting with making a die for the intake manifold and bypass cover for my little single cylinder two stroke engine. I believe that the old Brown Jr model airplane engine used pressed steel parts for these parts.

[@craigsmachineshop2040]

Thanks! Yeah, all kinds of uses for them!

[@CR-ho1vs]

Do you have any photos? Are the ends considered endcaps? Would like to see if you have time. thanks

[@EZ_shop]

Nicely done Craig! That'll be way faster than machining those plates. Ciao, Marco.

[@craigsmachineshop2040]

Ciao Marco. Thanks! I still have to machine the 3/16" and 1/4" tamper proof covers. This is to make my regular covers more professional. The original manufactures usually form them.

[@rongarza9488]

Now we can appreciate hail damage! It doesn't take much. (make the upper and lower out of ice and give that a shot!)

[@simonturner81]

"Crash form" with no real material control or restriction. In the real world this is done using nitrogen and a pressure pad in the center of the lower form, and in a lot of cases "draw beads" to further control material flow. Nice video none the less.

[@craigsmachineshop2040]

Thanks! It gets the job done.

[@OakwoodMachineWorks]

[@michaelrodgers5105]

Man I would love a small Chevy bowtie one.

[@helicopterjohns]

Never did any die work. AMAZING! I would have thought you would have needed the exact shape to get the nice rounded corners. Wonder how much it pulled the material in from the edges? Is the outer dimension still 3 X 3? Be interested to see the whole process. i.e. I was just thinking of the process I might try??? Sure you already have a good process figured out. 1. Cut the stock on you shear slightly oversize to accommodate for any shrinkage during the forming process and allow for a little machining stock of the outer profile to create a finished product. 2. Drill the center hole in the stock 3. Make the bottom section of the die with a threaded center pin of proper length (either heli coiled or Loctited) in place to guide the plate during forming. Of course you would need a clearance hole on the top section of the die to clear the threaded center pin during forming operations. 4. Remove the top half of the die and install the formed plate into the bottom half of the die and machine a plate out of aluminum to fit over the threaded center pin and hold the formed plate in place with a nut. 5. Then you could machine a perfect profile and chamfer if necessary the outside of the part with minimum machining effort.

[@craigsmachineshop2040]

Hey John! Yeah, worked far better then I expected! I saw another product with tell tail signs that they did something similar so I tried it. The shrink was only about 1/32" I think. I finished the die holding system for interchangeable dies. I should post by Mon or Tue. Its far easier than you might think. I held off for a long time thinking it was going to be so hard. LOL I have the covers laser cut to shape with the center hole now. I just need to form it. Yeah, I thought I was going to need a center pin to keep the part in place but after the test, I don't think I need it. I will probable have a lip about 1/16" out from the part for quick placement.

[@helicopterjohns]

I really enjoyed your video. Glad you are on the right track to success. Some times things are easier than they look. Using the KISS method is the way to go.

[@craigsmachineshop2040]

Thanks John! I Think I may have to use the center pin method when I make a die for curving covers. The covers will probably move around if I don't.

[@Hirudin]

The result looks great. Was there a bit of warping on the outside of the steel? Thanks for showing the test and I look forward to seeing the "real" one!

If I created a steel die for making an aluminum part that is 1/4" thick, would it be possible to sqeeze a plate of 1/2" thick material with a double pocketed die, and have the aluminum sort of flow into the die kind of like playdough in order to completely fill the die? I know nothing about this and am trying to figure out if I can stamp the part I've been working on or if I should mold it with liquid aluminum.

[@craigsmachineshop2040]

Sounds like that would need some extreme pressure. Depending on the qty you are going to make, either machining for lower qty or casting (molten) for higher qty.

Hi, how much tonnage do you think it would take to press 2mm aluminium, I think that's 14 gauge in your language.. to form a "joggle" or countersunk relief for creating a lap joint along the edge of a sheet for riveting purposes? The length of the die, press tool, could be around 6" long by 3/4" wide... I am wondering if an "Arbor Press" would be sufficient? Also at 5:40 in the clip , your using a very nice looking guillotine , what make and style is the?? thanks Paul, Mullumbimby, Australia.

[@craigsmachineshop2040]

Hard to say on the tonnage. I would think 12 tons would be more than enough. Not sure about an arbor press. 12 ton presses are like $140 here in the states. The shear is a 12" diacro.

I guess it depends on the size of the quarter panel but they usually require very large presses as you see in car factories.

@@craigsmachineshop2040 thank you Craig for your time and response. I know it would take quite a press to stamp out the panels and they ARE long quarters but they're 18 gauge steel, not near as heavy as what you have there. I know that with modern technology a CNC could be programmed to make such a contour from a program easily if a guy had deep pockets...but how was it done in the 60's & 70's? Would it literally require a block of steel for the top tool and bottom die the dimension thickness of the quarter itself? Let's take a 68' Charger quarter for example with the long coke bottle shape. The only thing I've seen was the equipment we had at an aircraft business i used to work for. We made fuselages and the floors for commercial planes. They made tool and dies for those but we were making composites similar to fiberglass.
