Major CNC update at Fiat Powertrain’s Campo Largo plant


A major update to the CNC systems of 20 key machine tools at Fiat Powertrain’s Campo Largo engine manufacturing plant in Brazil will extend the life cycle of vital production lines. The plant, which specializes in the manufacture of 1.6-liter and 1.8-liter E.torQ flexfuel engines for medium-sized cars, currently produces 230,000 engines a year. Campo Largo’s crankshaft and cylinder block production lines include 20 key CNC machines, employing more than 120 feed axes, originally controlled by NUM 1050 series CNC unit, NUM MDLU1 servo drives and NUM BMH series servomotors.
As the systems aged, troubleshooting, sourcing spare parts and general machine maintenance began to impact production throughput. Fiat Powertrain decided that NUM offered the best upgrade option for the plant, given that it was the CNC OEM for the existing equipment and could affect such a solution quickly, and with the optimum benefit/cost ratio.
“The fact that we are upgrading machines used for everyday production imposes some very demanding conditions,” says Campo Largo technical support manager Tarcisio Cruz Filho. “We needed a CNC supplier with the expertise and resources to collaborate on the design and installation of systems here in Brazil, while the systems themselves had to provide exactly the same level of functionality as our existing CNC equipment.”
Aiming for minimal disruption to plant manufacturing, Fiat Powertain and NUM decided on the latter’s Axium CNC platform as the least invasive solution for the machines. Opting for the same architecture as the earlier generation 1050 series CNC also meant that software modifications and wiring could be minimized.



The servo drives on each of the 20 machines will be replaced by models from NUM’s NUMDrive C range, while the motors on all feed axes will be swapped out for NUM’s BPH series, which have physically identical shaft ends, pilot diameters and flange squares.
The efficiency of such decisions has enabled for a faster upgrade process. “We allowed for a maximum of four days out-of-service time for each CNC machine on our crankshaft and cylinder block production lines,” says Filho. “Most of the machines on these lines have now been upgraded and, in each case – even on complex machines with seven controlled axes plus spindles – it has taken less time than we allocated.” Filho also added that the upgrades were on schedule for completion by the end of this year.
