The End-user is manufacturing components for military Humvee vehicles. The customer is machining a bracket made out of high strength alloy steel using a Mazak Nexus 510C VMC running with water soluble coolant.
Previously the customer was using an OSG solid carbide drill running at the following parameters: 766 RPM, 90 SFM, 0.007 IPR, and 5.36 IPM. The tool drilled a 0.4490″ diameter hole to a 0.75″ depth. The tool had a cycle time of 8.5 seconds and a life of 2500 holes. Unsatisfied with their current production process, the customer wanted to decrease their costs.
AMEC recommended the ASC 320® Solid Carbide Drill item #335M11400A21M running at a speed of 995 RPM, 117 SFM, 0.008 IPR, and 7.96 IPM. The results were excellent and met the customer’s expectations. The ASC 320® tool reduced cycle time to 5.6 seconds and matched the previous tool life of 2500 holes. The customer succeeded in decreasing their costs and saved $166.40 per 2500 holes.
Thanks to the successful performance of the ASC 320® tool, the customer was able to increase productivity and lower their costs to save 32% per 2500 holes.
