A customer manufactures and maintains components for offshore oil rigs. They use a Johnsford VMC with 1000 PSI coolant through the tool. The part they are machining is a component for a locking collar for an offshore pipe wrench made out of alloy steel.
Tool used: Cobalt drill (27/64" diameter)
- Hole diameter = 0.421″
- Hole depth = 1.20″
- Tap drill size for ½ -13 threaded hole
- 110 SFM
- 0.004 IPR
- Cycle time = 23.53 seconds
- Tool life = 468 inches
Seeking to improve their production process, the customer wanted to decrease machine cycle time.
Allied recommended the ASC 320 solid carbide drill.
Tool used: ASC 320 drill (3.5xD) (item #335E04219A21M)
- 300 SFM
- 0.011 IPR
- Cycle time = 9.4 seconds
- Tool life = 2,016 inches
The ASC 320 not only reduced cycle time, but it also decreased the cost of production while increasing shop capacity.
- Decreased cycle time by 60%
- Increased tool life by 330%
- Eliminated spot drill operation
- Total cost savings = $564.45 or 63.76%
