What is chip de-oiling?

Metal machining operations produce chips and swarf contaminated with cutting oils, coolants and emulsions. De-oiling centrifuges spin these chips at high speed, using centrifugal force to separate the liquid from the solid metal.

The recovered oil can be filtered and returned to the machine tools, while the dry chips command a higher price from metal recyclers. This creates a double saving: reduced coolant costs and increased scrap value.

CEPA de-oiling centrifuges are available as manual basket centrifuges for smaller operations, or as fully automatic systems that integrate directly with chip conveyors and coolant systems.

How de-oiling works

Metal chips are loaded into the perforated basket, either manually or via automatic feed. The basket accelerates to operating speed, generating centrifugal forces that drive the oil outward through the perforations.

The separated oil collects in the outer housing and drains to a recovery tank. After the spin cycle, the basket decelerates and the dry chips are discharged, ready for recycling.

Process steps:

  • Loading: chips fed into basket
  • Acceleration: basket spins up to speed
  • Separation: oil forced through perforations
  • Collection: oil drains to recovery tank
  • Discharge: dry chips removed for recycling

Why de-oil your chips?

Wet chips contain 5-15% oil by weight. Recovering this oil reduces your coolant consumption and purchasing costs. At current oil prices, de-oiling typically pays for itself within 1-2 years.

Dry chips are worth more to recyclers, often 20-30% more than wet chips. They're also easier to handle, with no dripping or spillage during transport and storage.

Economic benefits:

  • Reduced coolant and oil consumption
  • Higher scrap metal prices for dry chips
  • Cleaner workplace with less oil spillage
  • Environmental compliance for chip disposal

Frequently asked questions

CEPA de-oiling centrifuges can recover up to 99% of the oil from metal chips. The exact recovery rate depends on chip type, oil viscosity, and centrifuge settings. Typical recovery rates are 95-99% for most metalworking applications.
