Making a Slotting Machine for My Mini Lathe

[@DartDoran]

One day Maker B will build mini lathe from scratch... Nicely done

[@MakerB]

Maybe one day!

[@GordonWrigley]

I love the reveal at the end where you're basically like "look at this thing I could've done in 10 minutes with a file"

[@ali_hsj]

Your clips are so beautiful that one can't help but want to watch them over and over again.

[@MakerB]

Glad to hear that, Thank you very much!

Conceptually a great idea, well thought out , executed & a professional looking finished product. However, there are two areas of concern that I feel could be improved. The main concern is that all the longitudinal travel loads are being taken by the small stepper motor bearings. It appears to be a Nema 17 with integrated lead screw. Although these stepper motors with integrated lead screw are designed to take end load, they are not designed for the type of forces being exerted on them by your system. The second area of concern is the 'ball guide' system used for the alignment of the piston assembly very quickly wearing with alignment issues for the slotting cutter.

[@seleniumshutter]

could 1. be resolved with the addition of a thrust bearing to handle the axial loads, or would the rigid coupling between the leadscrew and stepper still result in too much axial loads being transmitted to the stepper? (I'm not an engineer... yet.) for 2. , I'd like to know what a suitable solution would be. The first thing that comes to my mind is a linear guide rail, but I'm assuming there's another solution of a smaller footprint.

FYI this is called keyway broaching. Slotting is something different. They make broaches for this kind of thing that you can use with a simple press and are much quicker. While I applaud your design, it is neat, it's got many problems which others have alluded to and would struggle with hard materials like steel and take forever. I'm assuming this was aluminum in the example.

[@peterspencer6442]

These machines are usually called slotting machines or slotting attachments, they are also sometimes called broaching machines but if you were looking to purchase something for your lathe or mill then "slotting" would be the keyword to search with. The two phrases broaching and slotting are mostly interchangeable but there is some nuance: Slotting is the application, whereas as broaching is the act of pushing a broach through or against a workpiece. A broach is customarily a multi-tooth cutting tool, or single-tooth for a rotary broach, because the tool cuts to its full depth in a single pass, whereas slotting is an incremental machining operation. They are not fully distinct and separate operations with no conceptual overlap, after all a shaper machine is not normally called a broaching machine even when being used to cut a slot. For my money I'd argue that Maker B named their beautiful project work correctly, it's a great complimentary tool to go with the nice precision Sherline lathe :)

dude what kind of mill and lathe do you own? any brand recommended? keep rocking man.

wow! Is it capable to slot a steel?

[@DolezalPetr]

very handy

[@hoodbaxter]

The whole time I thought you where making a slot machine

[@MakerB]

😅

[@memlafeder]

Everything was great and beyond amazing, but I didn't get it. (maybe because of my ignorance) Why did you need a device like that? Is there no way to create a notch, to inner side of a solid circle? Really I didn't get it.

[@GhostGraveyard-n1u]

Are the materials you use brass and aluminum?

Did I miss the part where an alignment jig of some kind is used to get the square part set correctly on the end of the round tube. Or, is this just machinist voodoo going on here?

[@matthiash.4670]

I thought the same 😅 But alignment is not critical for this part. You can place it basically in any angel you prefer.

[@chrisk.1539]

You could made it powering with USB.

[@nerddub]

hes using an external driver, which take more than 5v 2A, of which more would be needed anyway under these loads
