Getting Started With Milling Bits & Accessories, Plus Speed & Feed Rates (OX-Metal CNC)br>You're going to mill your slots to witdh and depth first before you start the T slot cutter in to do it's part. Most of the t-slots I've run into have the center slot a little deeper than the T cut to keep the T cutter from digging in. When you mention types of cutters are you referencing the roughing corn cob type vs finisher?
Key slot milling – roughing of full slot; Side milling – finishing all around the slot, using up-milling to create true square corners; The radial depth of cut should be kept low in finishing operations to avoid deflection of the cutter, which is a major cause of bad surface finish and/or deviation from a true 90° shoulder.
I am new to milling and machining in general and have a quesiton about cutting T-slots. I have 6061 aluminum and am using HSS T-slot cutter. I cut the neck diameter and depth to the appropriate size to accomodate the cutter, but when I switch to the slot cutter and begin cutting, the bit starts screatching as soon as I am a 1/2" into the peice (not even the full diameter of the cutter).

Harvey Tool - Speeds & Feeds Harvey Tool Specialty Profiles Slot cutter speeds and feeds
In typical slot milling, you are limited to make a slot only as wide as the slot milling cutter. Using an end mill in the trochoid method makes it efficient, and convenient, to machine several slot widths using the same tool diameter. Higher feeds and cutting speeds can be achieved when you use a small radial depth of cut.

Slot cutter speeds and feedsAny suggestions on which cutters to use and tips on how to use them?
Pardon me while I ramble on for a minute.
Back in my DeVlieg days I always cut cast iron dry sans coolant.
I was told that the iron would soak up the oil in the coolant and would not hold paint well the outsides of the parts were painted to match the presses they were made for.
Guessing that if you wont be painting, coolant would be OK.
You're going to mill your slots to witdh read more depth first before you start the T slot cutter in to do it's part.
Most of the t-slots I've run into have the center slot a little deeper than the T cut to keep the T cutter from digging in.
When you mention types of cutters are you referencing the roughing corn cob type vs finisher?
I have always used standard cutters, and cast iron should be a breeze.
I'd look for a cutter with the alternating directional teeth if I had to do it.
What info are you specifically looking for?
You can't sneak slot cutter speeds and feeds on the cut, so set the speed and feed appropriately.
For onesy twosey jobs I always left a few thou on the width and milled the slot to full depth.
Only after the T slot was cut, did I finish the slots to width.
Mill the T portion wet or dry whatever you wish.
and over in washington sure your coolant has enough flushing power to keep the chips from piling up around the cutter.
This creats a lot of splash so have plenty of splash guards set-up and floor dry handy.
I prefer to mill cast iron dry using a powerful shop vac and a fixed nozzle positioned to pull up the chips and keep the cutter clear.
Be sure you have a clean filter so the CFM is at its peak.
https://znamya-sum.ru/and/drilled-and-slotted-rotors-for-daily-driving.html production T slots are gang milled with stagger tooth cutters.
One machine roughs them to depth leaving finish stock on the width.
The next in line is tooled to cut the T slots and the next gang mills the width of however many slots there are on the workpiece.
The job turned out beautifully.
The cutter was doing just as good a job on the last slot as it was on the first.
Then, just recently I needed to cut T-slots in another MLA faceplate.
I got the job done, but just barely.
By the time I finished up the cutter was gnawing more than cutting.
I'd surely like to know what went wrong.
The casting seemed to be be all right because it cut beautifully on the lathe.
Thought I did both jobs the same, but am now wondering if I did things differently the first time around.
Do you supposed that the lack of rigidity had something to do with the cutter wearing out so quickly?
Next time I'm going to follow Forrest's advice and use a vacuum.
Perhaps I used one, earlier, but forgot about it.
They have staggered teeth that are cut on the end, side and back, so they have lots of clearance space for the chips.
It is still a good idea to use a vacuum to keep the chips from jamming the cutter.
You do not want to use any liquid coolant if you are using a vacuum, of course.
Gray iron cuts very well dry.
The graphite in the iron is a lubricant, after all.
Feed slowly enough that you can keep up with clearing the chips.
These cutters are expensive and they obviously cannot slot cutter speeds and feeds reground to their original size, which does a standard tee in one pass.
That means you need to be very conservative in picking your cutter speed so you slot cutter speeds and feeds dull the cutter.
That said, I have had to make many t-slots in sizes for which there is no available ready to use t-slot cutter.
In those cases, I used a Woodruff cutter of the needed size.
I usually had to grind a clearance on the neck of the cutter to clear the top of the slot.
Woodruff cutters only cut on the side, and have very little room for chips between the teeth.
So you feed very slowly and have to be very careful to keep the chips sucked out of the slot.
But they do work very well, with those precautions.
And don't forget Woodruff cutters are much cheaper than t-slot cutters and avilable in many sizes.

Go slower than you think you should on feed, then slow down a little more.
The shanks on those cutters seems awful delicate to me now for that kind of cut.
