- In this video, we will show How we made a completely customized Electric Drill Press by starting with a surface mount BLDC Motor rated at 300W from MAYTECH, a simple skateboard motor, bought online!
The project goes on by creating a complete assembly around this motor, taking care of all the details such as placing Position Sensors, proper mechanical mountings and chassis, and finally the design of a shiny enclosure and at the heart of it our motor controller SOLO UNO!
🛠️ The project is developed with the possibility of different motion controls, this drill press takes analog input to control speed, torque, and direction or provides a CAN bus connection as an extension for future developments to serve precision motion controls. 💡
💪 The heart of the system lies in the robust SOLO UNO motor controller rated with a 45A current.
🔩 Experience with the SOLO Motor Controllers' new possibilities ⚙️👨🔧 In this project we don't just drill, we expand our craftsmanship! 🌐🛠️

I have an old 60's drill press that currently runs a cheap brushless motor and controller from an industrial sewing. You've got me thinking about upgrading it to a configurable controller and quality motor.
yes, that will be the way to go 😉
The design looks sleek.
My first impressions:
1. Regarding heat: I notice there is still quite a lot of temperature variation in the enclosure. This indicates that possibly the air inside is not moving much (it should move due to buoyancy forces induced by hot parts). If you're goal is to keep the motor and controller a closed system, the heat sink is of course not going to be as effective but you might still find a benefit of using an internal fan or even orienting the heat sink fins vertically, or redesigning that sink to eject heat to the enclosure. Once that is improved the only other thing you can do is to make the enclosure out of aluminum as well.
2. The tools are definitely not fixed properly, that pulley was vibrating at 10:13 - 10:15. But it seems you knew that. Better to go higher drill speed and slower feed rate.
3. Another question is why you didn't use a thrust bearing, not that it matters much since the double row-bearing you use is very big anyways.
Looks very cool.
Thanks for your deep video assessment and high engineering interest! Replying to your comment step by step:
1. The design idea was that. Since the outrunner motor creates air turbulence inside of the enclosure, we decided to use it as the analog of a fan, mounting some rings on it to mimic a Tesla's turbine, however, there's still no air inlet in the drill body, which cause a lack of fresh air flow anyways. In addition, we need to say that the motor magnetizes all the chips produced during drilling, so the air inlet should be covered with another air filter. Thus, this transparent enclosure was mostly designed to show what was happening inside of the drill. For continuous usage, we of course will redesign the covers. Thanks for sharing your thoughts!
2. Yeah, that's true, the tools were not mounted properly, also the drill press has a transversal play, which causes some vibration issues.
3. We went with angular contact double row bearing as the first step toward the CNC head design, so the idea was to build a drill that at some point can withstand not only axial but also transversal loads.
Stay tuned there will be something more about this drill!
nice project. A pilot drill for drilling your pulleys. certainly a better way to hold the pulley whilst drilling, not the outer edge but the inner dia with v plates.
Thank you Gary, We are now working on improving this drill, the torque needs to be increased to have smoother low-speed performance, stay tuned for the next videos on how we are heading for that goal.
Nice build. Maybe a planetary gearbox about 5:1 would make much more torque and less heat
Thanks for your comment! We were thinking of testing the controller in the most critical load conditions. But yes, adding a gearbox could be a nice idea for further designs of this drill. Stay tuned to see it soon!
@@SOLOMotorControllers excellent! Google 'CM36 planetary reducer' these are cheap and look ideal for integration into your machine.
Thanks for the suggestion and your interest! We definitely assess this!
Nice project!
Thanks for the clear explanation.
Thank you! We are glad you liked it!
Very nice project and driver board.I would like to make a remote gear shifter for an manual gearbox,you know an H patern.I would need 2 drivers and what else apart of the encoders to work together and make that H patterns.They will be enough using an arduino board?Thanks
Thank you Max, yes, however for two controllers and 1 arduino board we recommend to use our CAN open capabilities which is fully supported on Arduino
I understand that this was probably made more as an experiment, but is there actually anything that this machine can do better than a Machinist's Mill?
I do realize that there is a rather substantial difference in price between the two, but I'm genuinely curios of what possible advantages there could be.
P.S. Centering your part in the vice in reference to the drill and then Clamping down your vice might help some with keeping the drill cutting straight.
Thanks for your curiosity!
We didn't think to compete with the milling machine, it of course does have many advantages, starting from a rigid frame, and complex gearbox and finishing with the working table with micro movement possibility. Honestly, we'd like to have one in our studio! 😊
Our idea instead was to design a simple and flexible direct-drive drill with fully controllable speed and torque, to test our latest version of SOLO UNO High Current controller to test it in the worst conditions and for use mostly in our R&D lab.
Talking about advantages we'd love to highlight its simplicity, flexibility of speed control, full torque feelings starting from the lowest speed, its lightweight and compact form, and user-friendly Motion Terminal interface in case if user wants to adjust motor control performance. Also, it is quite affordable, so everyone can repeat it and build one drill based on our project for use in a garage or home lab!
Regarding the vice fixing recommendation, thank you! We'll try this as soon as new pulleys arrive 😄
Was the enclosure all custom made? or did you just make some modifications to it?
the enclosure was completely designed by us from scratch 😉
Hi !
Great project !
I'm actually designing since last month a press drill using a BLDC motor. I'm using a Flipsky Motor Battle hardened 7070 110KV. What my surprise to see your video that just confirm the plausibility of my idea. But my biggest question was, How to power that thing ? you said that your are using your adjustable power supply and want to do the same. Is there a way to know what power supply you are using ? A big thanks in advance !
Thank you for your note, the power supply used for this project is DPPS-60-10 with 10A, we powered the motor at 36V, however same perfomance could be achieved at 48V.
looks like your problem with the pulley is not the drill but the wobbly mounting of your parts - but really nice drilpress anyways
Thanks for mentioning this! Yes, we are thinking about the proper positioning and alignment of the drilled parts in vises. Probably for the pulley-type parts machining we better design a mini lathe machine.
@@SOLOMotorControllersyes a mini lathe would be a great project to show off all the features a modern controller like Solo makes.
Hi !
Still me.. I made the error to buy the ODESC drive on the same website of the Flipsky motor 7070 and it seems to be a copy of the ODRIVE wich looks cool, but it is not the end application we have for our motor. You have. We are maybe looking to buy a new drive. I wanted to know if you had to play with the P.I.D. of the motor to be able so drill metal ? Ours choke on the lowest torque we apply to de drill. Was kinda dissapointed haha. Thanks !
We give the possibility to optimize the control base on several specific application.. have a look of our Motion Terminal and our website. if you feel we are an interesting match for your application we will be appy to assist you!
