The Challenge
The customer is machining structural steel tubes for galvanized towers using a custom built air liquid machining center with mist coolant.

Tool used:  Kyocera Inserted Drill
  • 800 RPM
  • 0.004 IPR (0.10 mm/rev)
  • Resulted in 3.15 IPM (80.00 mm/min)
  • Through hole
  • Diameter = 0.709" (18.00 mm)
  • Thickness of 0.236 inches (6.00 mm)
  • Cycle time = 4.4 seconds
  • Tool life = 2,100 holes
The current holders were failing on a regular basis. The customer asked Allied Machine to provide a reliable solution with performance improvements to replace their current tooling.
 
The Solution
Allied recommended the GEN2 T-A® Drilling System.

Tool used:  GEN2 T-A insert (item 451H-18) along with a special length holder with a body designed specigically for the diameter.
