BUILD IT, THEY WILL COME
Gonna Have A Large Time: This Michigan manufacturer pursues wind turbine and large-part machining in a big way, with massive machine tools.

The U5-1500 five-axis profiler allows multiple parts to be set up along the rail length and processed sequentially to support 24/7 production and optimize machine utilization. A 63-pocket tool chain rides with the machine to eliminate downtime associated with tool changes. Two five-position "wine rack" part stands carry oversized tooling that won't fit in the tool chain. This profiler features 33 m (108 ft) X-axis travel, a 30 m (98 ft) work zone and flexibility to do long-part machining.
This four-axis PT 1800 horizontal boring mill has a removable rotary table for an optional fifth axis. It has a maximum workpiece weight of 40,000 kg (88,200 lb). The one-piece column base and bed provide a rigid machining platform. X-bracing and wide column way spreads add structural integrity and minimize vibration.

A long-time contract supplier of fabricated and machined components to a wide range of companies, Dowding Industries, Inc. is making the leap to large-part production and the transition to the alternative energy economy. It is purchasing not one, but two massive machining systems from MAG Industrial Automation Systems for production of wind turbine components and large, critical parts for other big-machine makers. A Cincinnati U5-1500 five-axis profiler and a Giddings & Lewis PT 1800 horizontal boring mill are the centerpieces of a new state-of-the-art 35,000 sq ft  machining facility in Eaton Rapids, MI. It is operated by a subsidiary, Dowding Machining. Both machines were delivered earlier this summer and are currently finishing installation and prove-out.

A family-owned company, Dowding began looking for opportunities in 2006 to grow while avoiding the region's industrial downturn. It was particularly attracted to the potential for wind turbines and alternative energy, according to Jeff Metts, Dowding Machining president. "We saw an opportunity to be part of the 'new energy' solution."

To help in exploring that potential, Dowding enlisted the assistance of proven technology suppliers - MAG and its Michigan channel partner VMC Technologies. It had received strong service and support with 16 Fadal vertical machining centers at an existing contract machining facility adjacent to the new large-part plant, said Metts. "Being a dedicated, all-MAG plant worked well for us, so we approached them first with our plans. We made a decision early on with the purchase of the Fadal machines. The critical success factors were uptime and common controls. Service plays a big part in uptime and the team of MAG/VMC has been beyond excellent in responding to any need we've had. And, homogenous controls have allowed us to be ambidextrous within our machine capability and simplified our training programs."

The suppliers did extensive application and time studies based on wind generator part prints provided by Dowding, according to Jim Foust, sales engineer for VMC Technologies. "The detail and thoroughness of the reports were overwhelming," he said. "The studies included machine recommendations, fixturing, set-ups, tooling, cycle times and earnings per hour. They addressed the risks and unknowns, giving Dowding the comfort level, as newcomers to large part machining, to make such a major commitment."
