A flexible manufacturing system (FMS) comprising three Makino A61nx horizontal four-axis machining centres is now in place at the Warwickshire factory of Danfoss UK. The machines are served by an AGV (automated guided vehicle) running on a linear track along a storage and retrieval system housing 32 machine pallets that are loaded and unloaded at two workstations. The company is a subsidiary of the global, Danish-owned manufacturer of mobile hydraulic and electro-hydraulic products, compressors and speed controls for electric motors.

Following its turnkey installation by NCMT, sole UK and Ireland agent for Makino, the FMS replaces stand-alone production centres used in the manufacture of prismatic components from steel and aluminium. The components are part of integrated manifolds for the mobile hydraulic industry.

The Makino machines offer a rigid, robust spindle capable of delivering both high speed and torque. Each HMC features a 313-tool magazine, minimising the need to replenish cutters between batch runs, despite the throughput of both high-mix and high-volume production. Danfoss can route any pallet with a fixtured component to any machine, limiting the amount of movement necessary and providing considerable flexibility and productivity. Machine utilisation is close to 100%, as there is always a part waiting for immediate presentation to one of the spindles.

The automated system allows the manufacturer to run the facility 24/5 and at weekends when necessary. Two operators manage the cell during each of two day shifts, followed by unattended operation from midnight until 06:00.

NCMT supplied applications engineering support throughout the project, ensuring the efficient transfer of programs from the previous machines to the new Makino models.
