Investment in excellence
One plant's improved productivity and quality was repaid when the company expanded the facility
How do you measure productivity? By OEE? By defects per thousand? Is there a dashboard you look at, a Lean manual you consult to figure out how productive you are as a facility?
Here’s a new metric to consider: How many capital investment dollars is your senior management willing to put into expanding your facility? In Marion, N.C., the answer is a LOT of dollars.
When Baldor was acquired by ABB two years ago, the plant had just completed a major capital investment to manufacture taper roller bearings previously sourced from India. However, additional capital investments were needed to address other capacity constraints exposed by recent growth. A decade-long effort at improving quality, reducing waste, and emphasizing safety as a core principle already had earned Baldor’s Marion facility top awards from Industry Week and the North American Maintenance Excellence award. Even with the acquisition costs involved in adding Baldor to its global portfolio, ABB looked at the opportunity to expand on Marion’s track record of excellence and signed off on a significant expansion of the facility.
The move has allowed Baldor to position Marion for future roller bearing growth.
“Not only does the expanded manufacturing footprint support our roller bearing growth initiatives, it has also allowed us to create a new future state layout for our existing processes,” said Marion plant manager Mark Earley. “This future state will facilitate additional work combination, point-of-use material delivery and storage, and improved product flow. It also allows us to strategically position our dynamic ‘build-on-demand’ cells to reduce component and finished goods distance traveled by 65%.”
The 96,000-sq-ft expansion in Marion included literally raising the roof —to 24 ft, 4 ft higher than the existing plant. It allowed for an expansion of the manufacturing cells to insource large diameter housing machining, as well as gave the plant the flexibility to move existing workstations to further improve efficiency.
But the work floor isn’t the only place where flexibility is crucial to Marion’s success. The Baldor plant has just two operator classifications: Machine Operator and Utility Operator. The latter handles assembly and material handling functions. The work is standardized to less than 20 specific jobs in each classification.
Rather than limiting the jobs an operator can learn or perform, maximum pay is dependent on proficiency in at least four specific jobs, and many of the employees are proficient in twice that many.
This kind of work system puts the onus on continual training and improvement, but the end result is a more flexible workforce that can be assigned based on work load and personnel issues in a given day or week. Like baseball players, workers check the starting lineup each day to see where they’ll be assigned. For the 135 workers on three shifts at Baldor, every day is unique.
“The broad definition of job classifications provides us a flexible workforce that can react to our daily customer demand. This structure requires a commitment to in-depth training with dedicated training resources,” Earley said. “We also don’t let business conditions shortcut training. This focus on training is not only impactful to customer service and product quality, it also protects our capital equipment and tooling investments from costly mistakes.”
Earley added that flexibility has helped both the productivity of each station as well as the workers. “They understand the competitive advantage that their flexibility and their skills provide,” he said. “We have found that most employees like moving around versus being tied to one cell indefinitely.”
A more flexible, diverse workforce allows Baldor to build its core competencies in cast iron machining, its tapered bearing manufacturing, and in final assembly. That has led to improvements in operational statistics.
