Thread Rolling at Keystone
Thread rolling is a process that uses tooling dies and constant high pressure hydraulic force to compress threads into a steel rod. Transferring die geometry to a rod, or bar, is the result of a physical property called anisotrophy (an-eye-so-trophy). While cutting threads make a rod weaker and more vulnerable to failure, rolling changes its form through compression, making it stronger.
4 Benefits of Rolling vs Cutting Thread
1. Material Saving
The diameter of the blank is between the major and minor diameters of the threads and varies with the material, type of thread, and thread specifications.
2. Increased Strength
Rolled threads maintain grain structure in continuous, unbroken lines following contours, increasing tensile and shear strength.
3. Improved Finish
The smooth flanks of rolled threads provide better surface contact with mating threads so burnished roots and flanks are free from chatter, tearing, and cutter marks.
4. Sustained Accuracy
Thread rolling is unique in its ability to maintain accuracy of the original set up during long runs of high-speed production.
