    • 0.008 IPR
    • Cycle time = 1 minute 23 seconds
  • Kennametal boring process
    • 1168 RPM
    • 0.003 IPR
    • Cycle time = 1 minute 59 seconds
  • Overall
    • Hole depth = 7.0″
    • Hole diameter = 1.0625″
    • Total cycle time = 3 minutes 22 seconds
The customer needed a more cost effective solution. They asked Allied Machine to decrease the cycle time and reduce the overall cost of production.
