DIY CNC Milling Machine Build (Part 15) – Mounting the Spindle, Machine Alignment and First Chips!

Seabass Engineering

March 8, 2023



This time I mount the spindle, wire in spindle control to the CNC controller, align the machine and finally make some chips!

Final part was made using a 10mm indexable insert style cutter, 20,000 RPM, 1.5mm DOC, 1400mm/m feed rate..

Enjoy!

My objective for this project is to design and build a CNC milling machine without the need for any machining of the parts. Ordinarily, building a mill requires a much bigger mill to get the axis surfaces flat and parallel.

By using aluminium tool plate (which is in theory pre-machined flat) and bolting the critical components rather than welding, it should be possible to avoid any machine work. After all, I’m building a mill because I don’t have one!

Linear rails and ball screws are the cheap Chinese 20mm style that you can find on eBay etc.

DIY CNC Milling Machine (Part 10) – Building a DIY Power Supply & CNC Machining the Z motor mount

Seabass Engineering

December 16, 2022



In this episode I use my brother’s CNC router (that he originally built for making guitars) to machine out the Z axis motor mount and I build my own 70 volt DC power supply for the stepper motors…

Transformer: Toroidal 750VA 230v AC – 24 x 24 AC output – wired in series – AirlinkTransformers.com
Vishay GBPC3504-E4/51 Bridge Rectifier
3x 4700μF 100V DC 35mm Capacitors
2x 1K2 5W resistors wired in series to discharge capacitors when mains power removed.

Still to do – Fuse the 48V output from transformer and individual outputs to Stepper Drivers.

DIY CNC Milling Machine Build (Part 14) Building a CNC enclosure with 3030 aluminium extrusion

Seabass Engineering

November 30, 2022



In this video I’ll be building the enclosure around the machine. I have used 3030 aluminium extrusion to construct the frame and 4mm polycarbonate for the doors and front panel. I used a cheaper (but arguably less safe) material for the sides where people are much less likely to be stood if a cutter tries to escape!

I also make some rail extensions and install bellows on the X and Y axes, as well as begin to mount the spindle clamp to Z axis.

In the next episode i’ll be mounting and wiring up the Chinese 3KW ER20 spindle!
