The Challenge
A customer manufactures orthopedic instruments and implants for the medical industry. They use a HAAS VMC with water soluble coolant to produce their products. The part being machined is an orthopedic component made from stainless steel designed to support a human vertebral column.

Tool used: Original T-A insert (item 180N-13) with modified holder
  • Hole diameter = 0.437″
  • 250 RPM
  • 0.005 IPR
  • Cycle time = 4 minutes
  • Tool life = 25 holes
The customer wanted to remain with Allied products, and they requested a solution to further improve the hole finish and increase tool life.
The Solution
Allied recommended a slightly different Original T-A insert.

Tool used: Original T-A insert without chipbreakers and with TiAIN coating to improve heat resistance (item 180A-13-NC)
  • 280 RPM
  • 0.005 IPR
  • Cycle time = 4 minutes
  • Tool life = 100 holes
The Advantages
The change of Original T-A geometry and coating successfully improved the tool life and the hole finish.
  • Provided 4x the tool life
