Wire Drawing & Rod Processing worked example

Lubricant Consumption at 98% lubricant transfer efficiency: a worked example

What does the result look like when lubricant transfer efficiency reaches 98%? The full calculation is worked below with real intermediate numbers. Use it when lubricant consumption in wire drawing and rod processing needs a buy quantity for the next wire drawing and rod processing run and you do not want to short the line.

The inputs for this scenario

  • Wire length (or mass) drawn: 500 units (unchanged)
  • Lubricant used per unit of wire: 0.08 units (unchanged)
  • Lubricant transfer efficiency: 98 % (raised for this scenario; the documented default is 85)

Working through the calculation

  • Applying the documented formula (Required lubricant consumption = covered amount × use per unit ÷ transfer efficiency) to the inputs above produces each figure below.
  • At this operating point the engine returns 40.82 units for required quantity, the number this scenario is built around.
  • At this operating point the engine returns 40 units for theoretical amount.
  • At this operating point the engine returns 0.82 units for loss allowance.
  • At this operating point the engine returns 98 % for efficiency.

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 13.27% below the baseline at 40.82 units.
  • A figure at this level is achievable when lubricant transfer efficiency is genuinely sustained, not just peaked for a shift. 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.

  • Required quantity: 40.82 units (headline result)
  • Theoretical amount: 40 units
  • Loss allowance: 0.82 units
  • Efficiency: 98 %
