P1. Lite & Powerful Brusless CNC Spindle Build For 3D Printer. The Idea & Overview

P1. Lite & Powerful Brusless CNC Spindle Build For 3D Printer. The Idea & Overview

Hey guys, in this video I show the parts I have gathered for a custom CNC Spindle. I wanted to show you what i had in mined.

i was using an air tool that really worked well! however it was noisy and used to much air, its not piratical for every day use!

some parts were better bought than made, so i have a few parts to chose from. The hand piece is a Foredom H43T. you can see the specification’s here: http://www.foredom.net/h43t.aspx

I went with this one because it was compact and had a collet that would go up to 1/4″ i could have also made this part but that is a lot of extra work, I’m lacking time 🙂 its a bit pricey, you might be able to find the shaft on line and make the housing.

the motor is a Turnigy P2627L EDF Outrunner 4200kv for 55/64mm 3 phase RC motor, its designed for a ducted fan. so its dose not have as much torque but instead it has a lot of RPM, at full speed it will reach 45,000RPM with no load. and pull 22.2A @ 11.1V! That’s 250W! not bad for something so small. the best part is its only 12$! I can switch it out with a slower more with more torque if i need to, but i plan on using tinny end mills for my projects so it should be fine. I could use a gear reduction to get the lower RPM but still have a lot of torque.

The control is a 25A Turnigy TY-P1 25Amp HEXFET Brushless Speed Controller. seems to do the job and for 10$… you cant beat it.

The rest of the parts I will need to make, connector plates and shaft coupling. see those in the upcoming Videos!!
