Belts vs Leadscrews and Ballscrews for CNC Design
Realistically, we are unlikely to actually want out our 4 fluted 8mm mill end to move at 30 m/min or almost 100 ft/min (from graph 1), however a 20mm drive pulley could actually give us this speed! Of course, as noted these figures only apply for direct drive systems, and big, powerful CNC machines driven by belts may require larger sizes with ...
