I tried a new technique for making a brass label. I hasten to add that the technique is new only to me.
The label after engraving on the CNC mill
This is my engraving setup. A 26,000 rpm 2kw head, clamped to the main spindle, and controlled independently. The Z and XY axes are controlled separately by Mach 3. I turn off the main spindle to avoid embarrassment.
Using V-Carve Pro to generate the G code, and Mach 3 to run the mill. 90º V bit, run at 18,000 rpm, 100mm/min. Not a bad result. Not perfectly centered. I will mill off 1/2 a mm on the right
Then a coat of gloss paint. That looks interesting, no? The paint does not adhere to the sharp edges. I might use that as another technique in the future.
The surface paint is removed with 600g wet and dry, leaving the paint in the engraving.
The contrast of the black on brass makes the wording easier to read.
BUT. I should have waited for the paint to dry completely before sanding it. Some of the dust has been embedded in the still wet paint, reducing the gloss and making it a bit dull and fuzzy.
Also, the surface needs to be finished with a finer grade of wet and dry. Then lacquered.
