Threaded rods vs. ACME rods There are many methods of accomplishing linear power transmission, otherwise known as linear movement. Anything from a simple wheel, to a gear on a rack, to rubber belts will work. However, for hobby CNC machines, the most common method to accomplish movement is using threaded rods, or ACME rods.
After you determine the fundamental type and size of the CNC machine you want to build, your next step is to choose linear bearings. Your choice of linear bearings is one of the most important decisions you’ll need to make. Linear bearings are the mechanical devices that allow parts of the CNC machine to slide […]
