Cincinnati Mine Machinery celebrates 100 years of serving the mining industry

CMM will unveil a special 100^th anniversary display at National Mining Association’s MINExpo 2024, 20 – 24 September in Las Vegas, Nevada, and will also make a significant contribution to the Tunnel to Towers Foundation, an organisation founded after the tragedy of 9/11, to honor first responders and veterans who lost their lives or have been severely injured while protecting citizens’ freedoms.

Founded in the early 1920’s the company was acquired by Edwin P. Stenger in 1924, beginning a long history of leadership by the Stenger family. Robert (Bob) Stenger, current President and CEO, is the grandson of Edwin Stenger. Bob has long been a leader in the mining industry, having served more than two decades on the board of the National Mining Association, where he has worked to ensure reliable and secure supply chains; shape public policy; and champion environmental, safety and labour standards.

Anthony (Tony) Stenger and Robert Jr. (Bobby) Stenger represent the fourth generation of Stengers at CMM. Tony, Operations Manager and Treasurer since 2015, joined the family-operated business as a teenager. Bobby started with the company in 1998 and has been leading the Company’s sales since 2021 as Director of Sales and Marketing.

“It’s an incredible accomplishment for any company to survive 100 years,” said Bob Stenger, “much less to do it as a family-owned and -operated business. I think this milestone reflects the strong partnerships we’ve developed over the past century by manufacturing rugged and reliable components that have enabled miners to do more and deliver more every day.

“Our ongoing commitment to first-rate service and matchless innovation is tremendously important because this is not just the place where we work – it’s our family’s history and legacy.”

During product development, CMM engineers and sales representatives with hands-on experience in mine equipment maintenance go into the mines to get direct feedback from miners on what is and is not working to enhance overall component performance.

Cincinnati Mine Machinery initially focused solely on cutter chains. Their forged block and connector distinguished the product from cast-and-fabricated alternatives, and helped establish CMM’s reputation for quality and durability and began an unbroken chain of innovations dedicated to enhancing productivity in the mining industry.

In the early 1970’s, CMM introduced its universal connector conveyor chain, which remains widely recognised as the strongest chain available. During the 1970’s, they developed the 814 Ripperveyor chain, for the JOY 11CM miner, and the 734 chain, for the Jeffrey Heliminer 120-H machine. These two chains represented significant advancements, both for CMM and miners, who immediately achieved higher productivity and longer service life.

“Our business has been built by emphasising research and development to provide quality, long-lasting solutions for the mining industry,” concluded Bob Stenger. “And we are looking forward to forging the future of mining productivity.”
