Lubricant Consumption at 61% lubricant transfer efficiency: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop lubricant transfer efficiency to 61%, then walk the calculation through step by step. Lubricant Consumption sizes how much drawing lubricant — soap powder, drawing oil, or emulsion — you actually need to buy and stage for a run, given how much wire you're drawing and how efficiently the lube transfers into the die.

The inputs for this scenario

  • Wire length (or mass) drawn: 500 units (held at the documented default)
  • Lubricant used per unit of wire: 0.08 units (held at the documented default)
  • Lubricant transfer efficiency: 61 % (the input this scenario stresses; the baseline uses 85)

Working through the calculation

  • The calculation starts from the formula this tool documents: Required lubricant consumption = covered amount × use per unit ÷ transfer efficiency.
  • Required quantity works out to 65.57 units at these inputs, and this is the headline figure for the scenario.
  • Theoretical amount works out to 40 units at these inputs.
  • Loss allowance works out to 25.57 units at these inputs.
  • Efficiency works out to 61 % at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where lubricant transfer efficiency sits at 85% and the headline result is 47.06 units, this scenario comes in 39.34% above the baseline at 65.57 units.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to lubricant transfer efficiency, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It uses a single average use-per-unit and efficiency figure; real consumption varies with die geometry, reduction, wire speed, and how often boxes are recharged, so treat the result as a planning estimate.
