I want to build a drill press for shits and giggles, me still not owning one and hopefully turning into a soft mill later on.So far i got a working 3d printer, rods, nuts, concrete, all the boring parts and pic rel in 750W version. Just ordered linear rails for Z. However i'm really starting to struggle with english here. How do i get a drill chuck on there, as in, what parts am i missing and what are they called? I thought the motor would be the spindle when doing a direct drive, but the spindle is just a mount? And when looking for something like a drill chuck adapter, google greets with a plethora of morse tapers, which is great i guess?Given that even chatgpt can't grasp what i want to do, i'd appreciate some help on the necessary vocabulary.
To make it really clear; i want to take pic rel, mount it somehow on the motor and start drilling holes.
>>2890582Yeah, to make your drill press, you just need a lathe. Then you turn a part that one part fits the shaft of the motor and somehow secures to it, one part takes the thread of the chuck.

>>2890583These exist for straight shafts. In all sizes. >>2890583This is called a Jacobs chuck. The common tapers are B16 or mt2. You probably want something like pic related.You don’t see shaft to morse couplers very commonly because they have threads on the other side usually to hold a pulley. This part is called an arbor. Eg an 3/8 mt2 threaded arbor has a 3/8 thread on one and an mt2 taper on the other
>>2890585In a perfect world, maybe, but then i still wouldn't know what the part i'm making is actually called by.>>2890604>chinkshit drill pressThat wouldn't be no fun.>>2890604>>2890616>collect adapter>Jacobs chuckThanks, anons. You may laugh but i spend close to two and a half hours on google and ali by now, just to get anything close to this.
>>2890582Are you going to control it or just let it spin at 3000rpm? If so do you have good suggestions for a matching chink drive for it?
>>2890628Ideally i want it to hook onto a 4modi switch with off-2k-4k-6k, but that's not fully fledged yet and lower priority. I plan on using the controller that came with it.
What kind of torque do those motors make, are they steppers? And no I'm not getting out my fucking magnifying glass to try and read those specs... You do realize most drill presses have a belt or gear reduction in order to get the torque necessary to drill right? Chucks can be had in different flavors. Some of them are threaded and have a left hand screw in the middle of the arbor that keeps them from unthreading themselves when used in reverse. Some of them are a Jacobs taper. Whatever you decide to use as your drill chuck arbor will have to have something along those lines in order to use off the shelf common chucks.
>>2890633if the driver is a step/direction input you can use one of these cheap pulse boards for control https://www.aliexpress.us/item/3256806208621777.html
>>2890662>>2890664It's a 750W AC servo. I'm sure it'll do fine and if not, i'll throw in a planetary (or rebuilt the whole into aforementioned lathe). Sorry for the tiny picture, i was only slightly frustrated when opening the thread.
>>2890583Will the motor bearings take the axial load? Many do not. And that's why the motor drives a spindle with a belt. Spindle has bearings and an advance mechanism designed to take the load.
>>2890582Just cast some iron in your moms backyard Then scrape your box ways flat If mori seiki can do it so can a neck beard with a 3d printer
>>2890582If you go on eBay, you can buy fanuc motors, fanuc drives and a fanuc controller for pretty cheap And if you call fanuc and ask for tech support from their Cnc department they give free advice You can build your own mill or lathe using their controls especially with the kits from eBay where they have the frame, ball screws, linear rails and z axis assemblies
