The customer is machining a turbine housing sensor made from 347L stainless steel. They use a Kiwi HMC with a water soluble coolant-through.
Tools used:
- Vermont spot drill (0.860″ diameter)
- Cycle time = 1 minute 30 seconds
- Tool life = 100 parts
- Vermont cobalt drill (0.375″ diameter)
- Cycle time = 1 minute 26 seconds
- Tool life = 50 parts
- Vermont cobalt drill (0.4687″ diameter)
- Cycle time = 1 minute 36 seconds
- Tool life = 50 parts
- Line Bore (0.5″ diameter)
- Cycle time = 7 minutes 18 seconds
- Tool life = 70 parts
Overall process:
- Hole depth = 1.25″
- Cycle time = 11 minutes 50 seconds
- Tool cost = $50.00
The customer was unahppy with this process and needed to reduce cycle time and decrease tooling costs.
Allied recommended the EcoCut tooling.
Tool used: EcoCut holder (EC12R-3.0D 06 H-E) with insert (item XCNT 060202 EN CM40 grade)
- 2832 RPM
- 350 SFM
- 0.004 IPR
- 11.33 IPM
- Cycle time = 51.6 seconds
- Tool life = 70 parts
The EcoCut tooling dramatically reduced the cycle time and also eliminated three tools in the production process.
- Eliminated 3 tools
- Overall cost savings = $1,323.82 or 92.2%
