Makino IAC optimises direct-drive table rotation pallet by pallet

Makino says its Inertia Active Control (IAC) will make its nx designated horizontal machining centres more productive by reducing non-cut times from direct-drive (DD) table rotation.

David Ward, Makino's horizontal product line manager, comments: "IAC technology evaluates and optimises the acceleration and deceleration settings on a per-pallet basis. For a production manufacturer, this could mean thousands of additional parts being produced on each horizontal machining centre over a year." Makino's direct-drive rotary table provides inertia feedback from the B-axis motor to the machining centre's control system. While acceleration and deceleration rates for standard rotary tables are typically set for maximum inertia and weight to ensure accuracy, IAC uses data from the DD rotary table to quickly evaluate and adjust acceleration and deceleration settings to optimal levels for the specific pallet condition. IAC technology is available on Makino's nx line of horizontal machining centres, the a51nx and a61nx. These 40-taper machining centres feature pallet sizes of 400 mm and 500 mm, respectively.
