I have a complete Renesis rotating assembly that im going to use on my Peripheral exhaust motor. And im going to be using the one piece carbon seals from mazdatrix since the car will be all motor. can i take the rotors to any machine shop and have them mill out the apex seal groove to fit? or is this not something any machinist can do? and i need to send it to a capable rotary oriented shop with machining skills???

 

You have to send it to a shop that is familiar with it...
A regular machine shop can make this go bad really quick...

 

Kopoba does this kind of job all the time. He is in your area and his number is 407-466-5764

 

+1, take it to a reputable shop. And just for your info. Those carbon seals from Mazdatrix are made by Racing beat. Many products from Mazdatrix are made from Racing beat so you might want to check the RB website to compare prices.

 

^thanks for the tips everyone!

 

Just becasue im curious (and im actually starting machine shop school in 2 weeks) what exactly is done when machining them for the older seals?

just lowering the apex seal slot a few MM right?

 

Get them EDM wire cut.....machining them sometimes isn't as accurate.

I've done a set of Renesis rotors to accept the older 2mm carbon seals. EDM wire cutting was bang on, no problems.

 

whats EDM wire cutting?

and what does machining them entail? Lathe, CNC, something else?

 

I dont have a clue how you would lathe a straight slot LOL.

Usually people machine the rotor groove with an endmill in a milling machine, when your machining a 2mm wide groove 6-7mm deep (I think its roughly 6-7mm deep) The tip can wonder slightly sometimes giving you a 2.2-2.4mm wide groove, it may measure 2mm right at the tip, but it might not be the same the entire depth.

Extremely precise way of cutting metal.

 

wow... I guess i just made myself look like a real noob. lol... I start machining school on the 25th, so I probley will have these answers real soon anyways.

Thanks for the link...

 

Haha its all good, we all have to start somewhere.

 

ah ha! it just hit me...lol

i meant to say on a MILL not a LATHE! lol.... now i feel extra dumb. cant wait to start Machine school.

I remember when i first started welding i felt this same way. Then i went to school, got certified, and theres nothing i cant weld now. Cant wait to feel the same way about machine work!

 

Actually you can cut a straight slot on a lathe. You hold the cutter in the chuck and put the workpiece on the tool post. You could also use the tailstock and a broaching tool. Neither is very efficient but it can be done in a pinch.
