Fabrication of a Steel Drive Ring for the Manufacturing Industry

A customer in the manufacturing industry contracted Accurate Metal Products to fabricate the large diameter drive ring shown here. The drive ring was engineered for a rock crushing application, it required not only extreme strength but precision manufacturing as well.

Composed of A514 steel, the drive ring was comprised of three 120° segments, totaling an overall diameter of 154.000″, all of which had to meet tolerances of ±0.060″, and angular tolerances of ±1.00°. Fabrication required the use of a number of our manufacturing capabilities. Parts were also sand blasted before machining.
