The customer manufactures components for the aerospace industry using a Mori Seiki lathe with a bar feeder running with 300 PSI oil coolant. They are machining aerospace connectors made from 6061-T6 aluminum.
Tool used: Kennametal drill
- Hole depth = 6.0″
- Hole diameter = 1.4375″
- 3000 RPM
- 1129 SFM
- 0.012 IPR
- 36.0 IPM
- Cycle time = 45 seconds
- Tool life = 1,250 holes
Unsatisfied with this procedure, the customer needed to increase tool life and complete the entire drilling process in one operation.
Allied recommended the Original T-A.
Tool used: Original T-A drill insert (item 1C23A-0114) and holder (item 23030S-150L)
- Hole diameter = 1.4375″
- Hole depth = 6.0″
- 3000 RPM
- 1129 SFM
- 0.022 IPR
- 66.0 IPM
- Cycle time = 10.5 seconds
- Tool life = 10,500 holes
The Original T-A completed the process in one operation and provided significant cost-saving advantages for the customer.
- Reduced the cycle time
- Lowered the cost of production
- Increased tool life from 1,250 to 10,500 holes (740%)
- Total cost savings = $18,295.86 or 76.3%
