We designed and built our own DIY homemade industrial grade CNC milling machine to use for personal projects. This homebuilt machine is made from epoxy granite and has an 8 horse power spindle, servo motors all around, and an automatic tool changer. The machine weighs over 3000kg and works perfectly. All designs are my own and 100% original. We built this machine to help us produce better quality molds for our homemade plastic injection machine. Building this DIY CNC machine at home taught us a lot about milling machines as well as the physics at play, and we hope you find this video enlightening as well.
