A contract machine shop that repairs and maintains equipment for the oilfield industry is machining the base of a wench for an offshore oil rig made out of alloy steel. They are using a Lucas HBM NMTB taper with through coolant using RCA to produce their products.
Previously, the customer was using a national twist HSS drill running at a speed of 500 RPM and 0.006 IPR. Drilling to a depth of 4.0″, the drill created a hole with a 0.937″ diameter and had a total cycle time of 1.83 minutes. Seeking to improve their production process, the customer wanted to reduce the tool’s cycle time.
AMEC’s Application Engineers recommended a T-A® drill insert, item #151A-0030-NP, with holder #27010S-100L. It was advised that the tool be run at a speed of 620 RPM and 0.005 IPR. The results were excellent. Reducing the total cycle time to 1.79 minutes, the customer was pleased with the performance of our tooling. By reducing the machine’s cycle time, the customer also lowered their cost of production and saved a total of $81.05 or 14.54%
Using the AMEC tool, the customer achieved their goal and reduced the machine’s cycle time. Additionally, the customer received a total cost savings of 14.15%.
