Nice video, gotta admit it's very soothing to watch, almost puts me to sleep ! Lol I mean that in a good way, it's very relaxing to watch this machine cut so slowly and so perfect. I have drilled/slotted rotors on my car, now I know what goes into making them. Thanks for the great vid !
@corvettecentral Cast iron has graphite in it, and is a good "lubricant" on it's own. Generally, you don't need coolant for too many things, unless you are running the hell out of it. Being conservative with feeds & speeds will eliminate the need for coolant/lubricant.

If there slotted to that depth how long would they last before the slots are worn away but I'm like you do you're own and reap the rewards of the enjoyment of doing it yourself.
Notice how thick the rotor cheeks are. Looks like the Raybestos Advanced Technology line. Unfortunately most of the pre-slotted rotors (EBC, etc) are a few pounds lighter, not as thick, and have fewer vanes.
Nice! I am not familiar with stepper motors. All our equipment uses ac servos with servo amps running through our own NC. The stuff is so expensive tho, when I make my own cnc table, I'll prob have to piece it together slowly.
@sk8wnec Servos are the way to go but they are expensive. That's why I used steppers, I have less than $400.00 in the control system motors, electronics, ect... They are good for hobby but can lose steps if machining anything big.
@sk8wnec I did the retrofit myself I used 3/4" ballscrews for the X and Y and a pair of 1250oz steppers. For the Z I used a 700oz stepper with a 2 to 1 belt drive using the original gearing. For control I used the hobby cnc controller and an HP laptop running Mach3.
A clear example of #Niggerrigging

So what exactly is the point of doing this? Is it a performance thing, or a visual thing?

Why no lubricant?

@corvettecentral At the time I wasn't set up for it. In most cases cast iron cuts very well dry so I don't bother with the mess on rotors.

@JPN76 Thanks, would still think it will reduce the life of your cutting tool?

It may just be the camera angle, but it doesn't look like your slots are very parallel.

@sweetlikeADAM Look at my other vid "Slotted a brake rotor on a cnc mill" and you can see it at a better angle.

O I see. Ive never machined cast iron. Did you do the retrofit?

No cutting fluid?

@sk8wnec Well it's cast iron and cuts very well dry.

Any videos of cross drilled ones?

Not yet but working on it. That will be a much slower proccess without coolant
