One of the most important aspects of an open structure/low rail structure is it gives the maximum accessibility (loading/unloading) either from the front or from the sides. The travelling column design provides an easily accessible ground-level room for crane or fork lift truck loading and unloading.
Beyond this the workpiece can be visualized from different perspectives (this is not possible with suspended gantry structures), for being eventually machined again, without being taken out from the machine. This is very useful to prototype departments or any application where the design of the part must be validated before downloading the mould from the CNC machine.
in the early '70s mr marvi chiarottin founded chiarottin srl, importing and exporting woodworking machinery.
however, in may 1978, he decided to concentrate solely on cnc routers, and so set the future direction of the company.
the company prospered and evolved, developing specialist after-sales support services, and also expanded into spain, austria, the former yugoslavia, portugal and chile.
by the early '90s, customers began to demand more flexibility, and productivity. the style of cnc routers had to change as basic spindles became outmoded in favour of automatic tool changers.
