PBC recommended its IVT solution in a double bolt-on configuration to handle the large static and dynamic loads. The company precision machines aluminum extrusions for guides using its patent-pending process which creates more rigid extrusions that nearly match the strength of steel. The process handles all critical sides of an extrusion in one pass, generating a precise form with 0.002-in. flatness, ± 0.001-in. parallelism, and ±0.002-in./ft straightness This eliminates the need for fasteners and also cuts installation time. The grinding cell also required a guide system that could support the arm’s high roll-moment load. IVT easily handles 338-Nm static and 374-Nm dynamic loads, more than enough to provide the Equipois system with easy mobility.
