A contract machine shop repairs and maintains equipment for the oilfield industry. They are machining a down hole mud injection tube used in offshore drilling. The tube is made from heat treated alloy steel. They are using a manual lathe running with water soluble oil coolant through the tool with a rotary coolant adapter.
Tools used: Nachi Cobalt Twist drill
- Hole diameter = 0.750″
- Hole depth = 10.00″
- 475 RPM
- 0.005 IPR
- Cycle time = 4.7 minutes
- Tool life = 8 holes
Seeking to improve the production process, the customer needed to reduce the cycle time and decrease the cost of production.
Allied recommended a Original T-A drill.
Tool used: Original T-A drill insert (item 151A-0024) with holder (27010S-100L)
- 750 RPM
- 0.0065 IPR
- Cycle time = 2.55 minutes
- Tool life = 11 holes
The Original T-A lowered cycle time and increased tool life.
- Decreased cycle time by 45.7%
- Lowered the cost of production by 59.15%
- Decreased cost per hole from $14.14 to $5.78
- Total savings = $836.58 or 59.15%
