The main factory producing engineering models is Fujiyoshida, which obtains 2D and 3D data from the CAD Center and employs NC, MC, and RP systems to manufacture master models. A full support system that includes casting and rapid prototyping responds to each client's diverse needs.


Standard finishing machines, NC milling, a machining center, 5 axes double column machining center, and other types of equipment are used for "standard fabrication," which includes skilled manual fabrication techniques developed through years of experience.
Depending on the type of raw material, typical fabrication could involve a number of processes including solid cutting, bonding or welding, bending, or grinding. These processes also involve technical expertise accumulated through years of experience. ARRK is constantly updating its state-of-the-art fabrication technologies, not just to stay ahead through the use of the latest equipment, but to promote standardization in drawing analysis and fabrication methods, consistently supplying products of the highest quality.
