not sure if anyone gives a shit but if you guys are bored like me during the covid times then you can stream all of the latest series on Instaflixxer. I've been streaming with my girlfriend for the last months xD
Ever since CNCs became so popular (and most old machinists/toolmakers like me are gone) no one conventional-cuts anymore. I still rough pockets and circle interpolated blind bores conventional, then finish climbing - I thought the supervisor's eyes were going to pop out when I showed him how much faster you can rough down inside the part when you're not recutting your chips!
You really should run calibration run out on that probe. X y z the only time I take mine out is to change tips or swap batteries. They are ok to leave in the machine. Looks good tho. Keep making chips
I haven’t seen any cat eye chevys with a cummins in them so Isuzu has them covered lol. I don’t have anything against cummins engines it’s just the tin can that’s wrapped around them I’m not crazy about.
You really shouldn't smack the first op down with a deadblow. You should cut it in it's most relaxed state until you have square and accurate edges. Then tap it gently down onto your parallels or whatever on the second op. If you keep doing it this way you are inducing stresses or twists into the material. when you release it the material will want to spring back, and now the "flat" surfaces you just machined will be bowed or twisted. It might not matter too much for this application since it's getting bolted down all the way around but if you truly want the best sealing surfaces or you want it to be as flat as possible you should consider not tapping down the first op. Just a tip, other than that they look pretty killer
Can’t plunge cut with a normal face mill. I know they make some face mills that do it but you’re limited to .030-.050 depth of cut where they’re probably doing .125 at a time. More than likely doesn’t make much difference in the end
That makes sense. I’m not a machinist so I don’t know a whole lot. I just have a lot of family in the business and used to preset tools for acutec aerospace
dont tap you raw blanks into the vise on the first operation you dont allow the natural twist of the blank to be machined out and once the x&y is set program a pin stop in a tool holder to bump up against instead of using the probe every time and On the first operation you could use a 1/2 accurapro full dia cuts at .800 depth of cut at 12000rpm and 80 inches a minute then reaclamp the part before finishing to realeas the stress and lightly rea clamp and finish then the last op could all be done on a vacuum fixture so you dont have to use bolts to hold it down also when you go back and do engraving on the anodized parts you just put it on the vacuum fixture and suck it back down and it will all be set
PSD Leach You can’t really high feed mill aluminum just because you can put some serious work in with an endmill if you have a high rpm spindle. For example with a 1” high feed mill which is pretty small I can take 4.5 cubic inches a minute in steel. With a 1/2 endmill in aluminum running 7500 rpm at 1” doc .050 radial you can take close to 10 cubes. Obviously they definitely could increase their depth of cut and use chip thinning to their advantage, but they’re not.
We use a 2" Korloy F.M. in aluminum - while it's true you can't plunge straight down, I spiral/profile down into 6061 aluminum (which is what this cover is), ramping down .06 to .08 at a time at 200 - 240 inches a minute feed and at 7000 spindle rpm. To be fair - real world machining isn't what these guys are about.
Never heard of that brand machine. Only thing I can think of it might being without googling is if rottler makes a vmc. Kind of looks like milltronics.
It's a re-tag, I'm not sure if RMK makes any of their machines. RMK markets mostly to engine machine shops, most engine machine shops know next to nothing about real machine tools.
The part looks great. But for the love of god change your coolant out. not many coolants should look that way and my guess the smell is like a trash can. Xtreme Cut 250C Or Redline Rd3500. I run both of them in my shop.
Completely wrong paths, crap end mill and side lock holder. Climb mill path, Kennametal KOR5 end mill and Kennametal HydroForce chuck will rock your world. Watch one of Titan’s videos. 20K rpm and 1600 ipm. Boom.
Maybe but you don't know what his profit margins are on this part, how much he gets or how many he makes. That tooling set up for one tool is about $1,500 vs $200 or so for what he's got. Also I've never heard of that machine before, he might not be able to take advantage of a tool like that.
While not ideal, even using an ER holder would be a step up from a solid holder and lock screw setup. I've made V8 billet valve covers in a Haas using ER holders. I push it as hard as I dare without sucking endmills out of collets. I do agree if money isn't a factor a hydraulic holder would be ideal.
@@moorepower7 it depends on the quality of the tool holder, most tooling companies say never to put an end mill in an ER. A good quality sidelock is a better choice. I think the main reason is that you can't hold an end mill tight enough to guarantee no pull out when pushing a high end endmill hard enough to get good life out if it.
@@85CEKR Side lock holders definitely have their place, but in my opinion this isn't the place. I use side lock holders all the time in our big 50 taper horizontal cutting 4140 steel running +/- 2000rpm. When cutting aluminum in our VF2SS at 12000rpm, I want a balanced holder that doesn't have a screw on one side throwing off the balance. If you're not trying to run balls to the walls RPM, side lock works.......but it's a lot more fun to set the feed and speed on kill and watch the chips fly!
Those are some of the best looking valve covers I've seen!

@Jad Casen Yea, I've been using Instaflixxer for since november myself :)
Awesome video Greg cant wait to see more behind the scene stuff
That thing is beautiful. Awesome design
That is amazingly awesome cool cover.
Beautiful 🤩
That is just Beautiful.........Awesome
Great looking valve cover can't wiat to see whats up next
I’m here for Greg A 🤘🏽
What are ya, climb milling the whole thing?
And surprised there isn’t a locating hole for flipping it over

Toolmarks are very noticable.
I can see one of those coming to 🇨🇦 very soon

Ok ok so y'all got the Cummins engines covered but the important question is when are the lb7 duramax parts gonna be available
Austin Fraliex Cummins is the only thing worth swapping in another truck, that’s why

I'm shocked at how many people don't know this. They incorrectly assume that the raw stock is not twisted at all.
Couldn’t you use a face mill then come through with and end mill and finisher to speed up time?

12v one piece valve cover is this available ?
Plans for a dual cp3 gear cover next?
Can build valve cover for bmw m54 engine ?
How much do you sell them for ? 5.9 or 6.7 ?
Why are the tool paths different in each pocket of the valve cover
Their programmer is a trainee....
Could you make one for a cummins isx?
2nd gen 24v a no go?

You can send one of these right on over for my rig!
invest in a large fly cutter so there is not 3 face mill tool paths detracting on what should be a flawless base.
Something bad happened to the Z axis way covers

Yup - looks nasty, like it's 1/2 tramp oil!
what software
Is it clearanced for head studs?
Asking myself the same question did you figure something out?
Greg!!
Greg!!!
Push run forest run
