Customers make gears more efficiently with TimkenSteel by TimkenSteel | October 7, 2015 | Categories: Industrial Steel, Steel Industry Trends To make a finished ring gear for a transmission, our team begins with steel tubing, cuts it into rings and then machines teeth into it. Our customers then machine the component again to create the final gear with an expensive tool called a “broach.” The longer the broach’s life, the lower the manufacturing costs for the customer. TimkenSteel Technologist Mike Burnett gives you a behind-the-scenes look at the sophisticated engineering and perpetual innovation that reduced broaching costs for one customer by 67 percent.
