Today I will show you how I make some acrylic parts for Martin from Wintergatan and his Marble Machine X project. That was also a new experience for me because I didn't made something out of acrylic glass before. I'm really happy how this turned out.
I hope you will like this video and you will visit my channel again!

Speed and feeds I used:
Roughing 1 flute 6mm straight endmill
-Spindle speed: 15000 rpm
-Feedrate: 1650 mm/min (65 in/min)
-Feed per tooth: 0,11mm (0,00433 in)

Finishing 1 flute 6mm straight endmill
-Spindle speed: 15000 rpm
-Feedrate: 900 mm/min (35 in/min)
-Feed per tooth: 0,06mm (0,00236 in)

2 flute 8mm ballnose endmill
-Spindle speed: 15000 rpm
-Feedrate: 3000 mm/min (118 in/min)
-Feed per tooth: 0,1mm (0,00393 in)

I think it's pretty cool that he makes videos in German AND English. It allows a lot more people to watch and lets him practice English. What a legend.

hey did you know that you could use a heatgun to do the polishing? it works better than the torch because you can manage the heat correctly and don't risk to burn your freshly cut peace. However, you did a great job! And your polishing is super but you could have save time on the 280 marbles cavity ^^

tip for recording ya screen
OBS - free software, not heavy for your pc
and if your camera supports webcam mode, you could record the mixin screens at record stage so it doesnt need editing

nice vid anyways :)
