Case Study
A customer approached us with a dysfunctional grinder head used in large, high-traffic metropolitan areas. A different vendor’s externally threaded filler inserts did not fit into Craftco’s internally threaded hole, ruining the hole and making it impossible for the insert to be eventually switched out for a cutting tooth. Craftco used certified gauges to examine several of the inserts, the supplied grinder head, and the head’s threaded holes in order to determine if the issue was with the internal threads Craftco produced. Craftco took all grinder heads back and measured over 600 holes to make sure everything had been manufactured correctly.
After evaluating the threaded inserts to ensure specification for the triad series, Craftco found the root of the other vendor’s externally threaded inserts weren’t cut to the depth (it was a U-shape instead of a V-shape) and several of the insert’s major outer diameters were out of tolerance—meaning the threads weren’t meshing properly and could not function. Craftco relayed these results to the customer and were promptly contracted to make over 300 new threaded inserts; in addition, Craftco fixed other issues with drafting and printing in order to guarantee the new inserts functioned correctly. Finally, Craftco checked the inserts with certified thread gauges to ensure quality and delivered to the customer.
Craftco’s ongoing commitment to quality, care, manufacturing capability, continuous improvement, and customer service alleviated turnaround issues and improved downtime/ lead time for the customer. Most importantly, the parts fit as required and the grinder head issue was resolved.
