Sharp 2412S Video

[Brandon Dixon]

I too have one of those Sharp 2412S machines that everyone seems to love. I really like my machine as well. Like many others, I'm in a home shop, but I have a 32x36 separate garage shop at home.

There has been some video of these machines cutting hard stuff on here, so I though that I would post a video of it cutting some soft stuff...This is just barely past prototyping (I'm making 20 parts), so cycle time is not my absolute biggest concearn. The metal removal rate is still impressive to me. The cycle time on this operation is just under 1 hour, and about 20 minutes of that is the waterline finshing.

Very cool......
The Sharp machines seem to be gaining credibility weekly.

Brandon,
I wanted more machine porn. 8 minutes is almost like an olympic athlete.
Seriously though. Pretty cool part to dream up for your project.

-If you have time, I would like to know what spindle loads were on your machine for the ins. e.m. I'd also like to know the parameters of your inserted e.m. I'm pretty sure you could have taken half again or twice the .25 doc you were(depending on load).

-Did you start assembling any of the stuff I made for you?

Sweet!
I was hoping for some more good machine porn.


Now I have to clean up.

Do you have a chip conveyor on this machine?

What side does it exit?

What CAM program did you use?

Do you have the NANO upgrade?

Don't wait too long to make another.

The roughing uses up my HP. It's not shown well in the video, but there is a spot coming around the bottom of the part that the cutter is almost cutting a full slot. I've got my speeds such that the load is maxed out and the spindle rpm drops just a bit (maybe 200 rpm). The rest of the time, when the cutter is "normally engaged" the load is right around 100%. My computation puts the metal removal rate at 33 cu in/min.

I love that cutter, it's a Kennametal "Mill 1" with integrated CAT40 shank. Kennametal has some great alu. cutting inserts for that series. I have a face mill and that long insert cutter with the same inserts.

I'm not loading the spindle that hard with the 1/2" em. Just can't get the chips out of those pockets well enough, and the risk of scrapping a part with a chunk of carbide stuck in it is just too high.

It has the chip auger that pushes the chips into a bin on the left side.

This was all done with mastercam X2.

I have a base model 2412S. There is some AI contouring built into the standard control, and for my purposes it's just fine. I have about 220 spindle hours on my machine in 9 months. This is really just a hobby/obsession for me

Brandon,
Really nice machine pr0n. I liked the length, you actually get to watch what's going on. To many of these you see are way to short.

 

[Joe788]

That machine really sounds great when it's cutting. Drastically different than a Haas Mini.

Looks like it has great coolant pressure too!

Wow Great vids! How did you remove the rest of the material without damaging the finish ??

The part look awsome seriously !!!!

 

[Douglas mc]

I have to says this is a very nice part you made

 

[Michael Moore]

I enjoyed that. It is nice to see race car parts instead of chopper parts being made.

cheers,
Michael

I'd like to see how the part that was held in the vise was removed in the second op.

What is a Citation Formula car? Just a link to the series web site will do... (Bryan, machine tool porn lover and racer of cars nobody lets him work on...)

The second op is a lathe, if you go look in the eccentric loading thread you can see how it was held and get an idea for how we remove the material. you can also see pictures of the finished parts after anodizing.

Brandon shot some video of the lathe today and either he or I need to make a movie out of it to add to this thread.

Citation formula cars are for SCCA club racing. There is a non-winged version for Formula Ford(1.6L Kent motor), a winged version for Formula continental(2.0L Zetec engine), and another winged car for Formula 1000(1.0L motorcycle engines).

here is a photo of the prototype right after it went together and before paint(the colors are just some bad photoshopping).

Cool video! I'm in the sticks, took 3 hours to load on dialup, it was worth it, even considering I watch my sharp everyday! Very cool part, too.

I will say that I am impressed that you can pull down the spindle by 200 rpm without any problems. That sounds like alot to me. I try to keep my rpms at or very near programmed rate. But if it doesnt seem to hurt anything, why not?

 

[bucktruck]

Cool video. My boss is thinking about buying one of these machines to replace an ancient Leadwell MCV 610. I think I'll send him a link to the video.

BTW, it's nice to see someone making parts for cars that can actually go around corners. I make a few parts for early Porsche's, and hope that they are used on the track, as intended.

Ok thanks a lot !!! I'm waiting the lathe vids :P and I'll go check the other thread !

Thank

Nice video, Brandon!

I was very impressed with the photos you posted in a previous thread re: turning off balance parts. Finding out that you milled the parts on a Sharp mini is making me feel pretty good about my own 2412 (non-S model) that is being delivered next week.

I don't think that you will be dissapointed. I'd buy this one again, for sure!

Thank you for sharing!
