How much does it cost to have heads CNC ported?

i'm guessing a lot. from the little bit of time i spent in college writing programs for cnc machines i know it takes a while to write and takes longer to work out the bugs. on the plus side after you have it figured out you have it forever.

Wow!

Looks like I should be shopping for an old Mazak vertical...

I could do it for $850.00 a pair and still make money. Set it up, push "CYCLE START" and go in for dinner. Cool. A few pairs of heads would pay for a used-but-nice 20-taper mill...

vader, why stop with just porting? do a little reverse engineering and start selling 18* and 23* vader heads to all the thirdgens that stop by here.

You'd need some really good 3D software with that old Mazak vertical to really do it right. I have a few programs at work on Virtual Gibbs 3D, and a fully ported bowl takes a lot of work. I actually port matched a set of Dart II's on a MV-40 Mori Seiki Vertical (intake and exh)w/ Smartcam SM9, but I've yet to do a full porting job. But you're right, after the bugs were worked out, You could do 'em all day for $850. I'd take a .25 carbide inserted ball-nose, and run it about 4500rpm - 30in/min -- Maybe 3500 - 15in/min for cast, and have a cycle time of about 3.5 - 4 hours - $850 is good money for that amount of time, huh??

Basset,

Moris are a nice, heavy tool. Mazaks are light and cheap. (Why I mentioned them - cause I'm cheap, too!)

Fanuc conversationals would work nicely, and I was thinking a shperical cutter as well - even for the final finish on the chambers. The aluminum would load fast, even with the right coolant (then there's the soaping problem). Cast would be a breeze if you didn't mind the mess. I've been thinking of hunting down a small NC mill for a while, but even the E-Z Tracs are a bit pricey right now. If you have a couple mill to spare, you could get me a nice five-axis for my birthday.

However, I'm not that fond of the advert slogan "For the best head, see Vader." Not in this lifetime....

vader....i'd be willing to give you money towards the mill for a small percentage of the profits

 

Maybe you should start a cylinder head porting company. Then you could go about getting incorporated. After you were a corporation, you could issue stock to raise the money to get the machines that you needed...Vader Cylinder Heads, Inc., sounds good to me .

Alot of shops use a Serdi to do valve jobs,but you can also use it to port the bowls.Much cheaper than a mazak or any other VTL.

Im going to regret asking. How much are the mills? Im mean whats the price range for new and used??

 

The new Mori Seiki SV-40 4th axis Vertical I'm running now only cost about $320,000 . The machine I ran up until about 3 mos ago was a Mori-Seiki MH-40 4 axis Horizontal and it was bought used for S180,000.

And a well-used Mazak (cheapest) with an adequate table sweep to do one head at a time is going for about $35K in operable condition. Since the tolerances required aren't that critical on engine work, a fairly "loose" machine would suffice for a while. A good production machine capable of holding close to original tolerances would be in the $100K range if you found a desperate seller.

Right,

But I'll still be calling for information on the following topics:

1) Outhouse disappearing act using HE

2)Installation of a Rolls-Royce Merlin engine in a 3rd gen vehicle

3) How to move hay bales with a 4-cylinder Pontiac while winnig the main feature

4)The subtle nuances of using a dime-store protractor to calculate angle-of-re-entry for an insane man piloting an alternative-fueled rocket over the Hawiian Islands at sunset.

5)The latest and greatest in shark repellants and how to stop severe bleeding in test pilots.

6)Heat seeking updates for little tiny loads of C-4 aimed at intake runners using a pea-shooter that's been poked thru a cutout in the windshield of a 3rd gen car.

WAIT JUST A MINUTE !!!

THAT'S MY DOMAIN !!
