Competition The perfect head porting job

[qkoop]

Anyone have a perfect head ported by a proffesional they want to duplicate? I was looking at different cnc set ups and came across these videos. They also have a 1 and a half hour a video of how to build a program on their cnc bed mill. Any one who has ever done porting has to see this. Here is the link http://www.centroidcnc.com/cncvideo/video5axiscylhead.htm

Looks very impressive. Anybody got the $$$s to request a quote from a resaler? Don't even want to think about how much.

 

[qkoop]

It comes with 2 weeks free training. Oo.

 

[nwpadmax]

Does it have part probing for reverse engineering?

If not, you'll need a CMM or similar (Faro arm).

 

[zstroken]

I wasn't overly impressed with it. What parts are available? I troubleshoot CNC's daily, granted in a job shop it will fair better than on a manufacturing floor, but items do fail. nwpadmax is right, someone will have to spend some time deveolping the part program, or have a CMM get the dimensions off of a ported head.

 

[JVolpe]

From the how it works page on the web site.



The CENTROID equipped 5 axis machining center will be used to both copy the original hand ported intake and machine the new heads to the exact same shape.



The CENTROID Digitizing feature is used to copy the hand shaped intake runner. This is an automatic process, no operator attendance is needed. The CENTROID CNC control automatically copies the intake runner shape in 5 axes! The machine both rotates and tilts to perfectly reach all the detail of the port. You can both copy and cut the new shape on the same machine. CENTROID makes the digitizing process simple to operate. CENTROID Digitizing is highly accurate.



This super accurate probe has been specifically designed for cylinder head digitizing and outperforms other probes on the market.

 

[nwpadmax]

Cool.

You'd still think it would need some supervision unless it had a rough idea of the port shape to begin with. At some points (like near sharp turns) you'd run the risk of smacking the probe shank instead of the tip. But, I've never done it before, so I don't know if it has a strategy to avoid that.

Y'know, like where the bowl turns and heads down the runner... .

The CMM's we use require a program to be written. YOu have to tell them what points to enter the hole, and then tell them what dimensions they need to check. I supppose it could break the area up in a grid and then hit ever grid and just look for openings, but your probe would have to be super flexible or you would have to run the traverse speed super slow. Who knows maybe it sweeps the whole are twice(once to get the rough dimensions, then the second time to get precision dimensions) I am jsut thinking out loud. Somebody needs ot buy one and find out.

All For $19.99

They Make It Sound The The Best Machine In The World . Ha The A And C Axis On That Thing Would Be Destryed With One Crash . Best Ball Screws Ya Ok I Repair $750,000 Toyoda Machines All Day And I Dont Think That Pos Could Keep Up . But For None Production It Would Be Ok . It Probally Has Conversational Controls On It But Looks Like It Still Needs A Program Off Auto Cad Or Cad Cam Or May Be By Hand .

 

[nwpadmax]

Well, Mr. Negativity, who is God's Green Earth is going to buy a $750k Toyoda for machining heads for hi-po diesel trucks?

Geez. Think entry-level.

Betcha it doesn't take well to cast iron heads... you're right, probably not stiff enough. Or would take forever.

 

[Doug1810]

Sorry just watched the video and they are talkin like best in the world . But like i said for non prodution would be ok . just my $. 02 i dont like it when a company states all kinds of things because they dont think the people have enough knowledge about the product.

 

[zstroken]

I have seen CNC quality detriorate. Mostly lots of players have left the business. New Brittian, Ollffoson(I think the guys who worked there started their own), Saginaw is ok, but not built like they used too. Hardringe(need I say more), chiron, fuji, most of these require lots of maintance to survive a shop floor. I haven't used a Toyoda CNC, but the Toyoda grinder we have isn't the preferred grinder to use.

Go to:

http://rottlermfg.com/

They are a major builder of engine rebuilding equipment. Click on the P50. They go for about $250k preprogrammed for heads of your choice and factory setup and training. Pretty cool.

that looks pretty good for alum. not cast iron. i don't do the cnc work at my race shop, i do hand porting/finishing. we do 95% cast iron and that machine doesn't look to sturdy. the way our milltronics machine makes noise and the way those endmills dig in, i'm not to sure how long that will last. i'm sure it's possible it will work but how long? not sure. you'll have to have some $$ though for the software to go along with it. i bet that machine is in the 100K range easily. our shop went to an auction recently and 5-8 yr. old machines that were abused were going for $60-80k.



what do i know? i'm not a cnc guy, i'll stick to manually porting. less messy than alum.

 

[qkoop]

It looks fairly sturdy to me. It was climb milling a good 5 thou pass quite smoothly.

 

[RacinDuallie]

Doesnt have the space to fit up a Cummins cylinder head... .

 

[Doug1810]

I know a guy who has a little kitamora vetical for about $10,000 4 axis . I heard it looks nice . Michigan is a good spot to buy used machines right now economy is junk .

 

[RacinDuallie]

Link ? ? ?

 

[Doug1810]

No link just a small time guy with some good deals . but if you dont know cnc take a person who does not sayin the guy would rip you off but cya . p. m me if you need his number RD i cant get it untill monday .
