A custom job shop performs various thread mill applications. They produce a ¼” (6.35 mm) and ½” (12.7 mm) NPT joint made from cast steel. They use an Okua HMC with flood coolant. Previously, the customer had several steps in their production process that included drilling a hole, taper reaming, and tappping.
The customer experienced tool breakage and needed a better solution. They also needed to decrease cycle time while maintaining or improving the thread quality.
The AccuThread 856 thread mills not only reduced the cycle time, but they also improved the hole quality.
