CNC Milling Machine

Building a Portal CNC Milling Machine from Scratch — 1

Engineering Spare Time

November 13, 2022



DIY/ “Homemade“ Portal Milling Machine with automatic tool changer spindle SK30 (BT30). The overall working area of the machine will be about 550 x 650 x 450 mm (X x Y x Z). The total weight will be about 950 kg. The structure of the machine is a welded metal frame that will be filled with UHP concrete to improve the dampening. All the components of the machine (ball srews, linear rails, …) are industrial grade (Bosch Rexroth, THK, SKF, GMT, …). The machine will be power by NEMA 34 stepper motors for testing. Until everything is working as expected, those will be substituted by a servo drive system complemented by SICK absolute encoders on all axes.

The build and component purchasing started in 2016, since then we were able to get basically everything together that‘s needed to finalize the build.
The milling spindle is a spare part from an old (1990) Steinel BT20 5-axis milling machine

Some Specs of the Machine:
– X Travel: 550 mm
– Y Travel: 650 mm
– Z Travel: 450 mm

– max. G0 (X,Y) : 15 m/min
– max. G0 (Z) : 10 m/min
– Servo Power (later) : 400 W (max.)
– Spindle Power : 4,5 kW (i = 2.5)
– Tool Holders: SK30

– total weight: about 950 kg
– outer dimensions: 1000x1200x1200 mm (without housing and table)

I MADE A STEEL CNC MILL FROM SCRATCH (desktop version)

Somehow I got carried away by the comments in the last video and decided to sharpen my welding skills trying to rebuild the mill out of steel.

I remade the entire frame out of 40x40x2 steel box and TIG welded it using a technique called winging it. As a known side effect of this technique the frame is not square, straight, coplanar, or any of the required properties for the frame of a machine like this. I solved it by shimming almost everything on it with washers of different thicknesses and a lot of brute force. In the build of the aluminium one almost everything went perfect first try, in this build I had to wrestle with it a lot, way more than I’m capable to show in a single video. The machine is obviously more rigid than the aluminium one and after a lot of fiddling with it, it is surprisingly straight where it counts and seems to even be properly trammed.

As a bonus at the end of the video I decided to obliterate some aluminium and steel with the wrong dull bit and completely wrong feeds and speeds.

As always let me know what you think in the comments.

Thanks for watching!!

TINY 3D PRINTED CNC MK I (OLDER VERSION)

I made a CNC router using mostly 3D printed parts that can cut metal!
The machine uses a Makita router as the cutting tool and as I show in the video it can easily cut complex parts out of aluminium.
