Here’s an awesome CNC build that crosses a standard CNC router… with a CNC machine capable of milling metal with ease. Introducing The Ripper. No, not Jack.
[Maximilan Mali] has been reading Hack a Day since he was a kid. A few years ago, he saw a guide on a DIY CNC build which inspired him to start designing The Ripper at the young age of 16. He’s 19 now (studying mechatronics in Austria), and raised enough money last summer to finally build his first prototype. It cost approximately 4000€ to build, which is pennies compared to a commercial machine of this caliber.
The machine has a bed size of just over a meter squared, with a Z height of 225mm. It’s also rigid enough to slice through aluminum at 850mm/s with ease! Take a look at the following video — we’re very impressed. Our favorite part is when he shows off its accuracy and repeatability by plunging a tool towards the screen of his very own iPhone.
