The CNC mill is a big heavy beast at 2.6 tonnes and it needed to be mobile in the workshop. The base was designed to well exceed the capacity of a 2600kg static weight. I used 1500kg casters and 24mm studs with tophat nuts welded in place to allow for levelling once the CNC Mill was situated in the workshop. The calculated load capacity of the Mill stand is in excess of 6000 kilograms.
The arms that the casters mount onto were designed in CAD and waterjet profiled. The fabrication was completed using TIG welding in multiple passes to limit the distortion, maximise the route penetration and weld deposition.
