PROTOTYPING
Rotational casting machine
The idea is to make a huge bearing. The outer is connected on the x axis on a support base and it is connected to the inner ring by a circular array of steel balls so that the inner ring can rotate inside the outer one on the z axis. This prototype was CNC milled using two very common mill tips: a 12.7mm ball-end and a 6,35mm upcut squared-end.
