Industry · Aerospace & defense

Coolant systems for precision aerospace machining.

Aerospace and defense machining requires consistent coolant quality across expensive materials, tight tolerances, and demanding surface-finish specifications. EdjeTech provides coolant recycling, filtration, separation, and sump-cleaning equipment for these operations.

Configure equipment for the process and contaminant load

Machine count, coolant volume, required flow, materials, and surface-finish requirements determine the appropriate equipment.

  • Operation A

    Small & captive shops

    ≤ 25 GPM · single cell to mid floor

    Captive machining departments and small contract shops can use portable coolant transfer where clean-coolant piping is not practical.

  • Operation B

    Large primes & tier-1 plants

    multi-cell · multi-plant

    High-volume aerospace machining cells and multi-plant operations use C.R.O.S.S. configurations sized to total coolant volume, contaminant load, and required throughput.

  • Operation C

    Titanium & inconel grinding

    fines control · finish + safety

    Tight-tolerance grinding on titanium and nickel alloys requires media filtration matched to the fine-particulate load, coolant, and surface-finish specification. Additional separation stages depend on the complete material mix.

Why fluid condition is a quality variable

Coolant condition affects machining quality and scrap risk

Fines and tramp oil that recirculate through the work zone can affect surface finish, tool life, and coolant performance. Removing these contaminants supports process consistency while reducing coolant replacement and disposal.

Reduce waste volume and improve coolant housekeeping

Coolant recycling reduces disposal volume and supports cleaner fluid-management practices across the facility.

  • Coolant waste

    Lower disposal volume

    C.R.O.S.S. can reduce waste-disposal costs by up to 90%, lowering the volume of spent coolant that requires off-site management.

  • Exposure & housekeeping

    Bacteria and odor control

    Removing free oil and suspended contaminants reduces the material that supports bacterial growth. Optional ozone provides automated bacteria and odor control without routine biocide addition.

  • Titanium-specific

    Class D fire hazard

    Titanium fines require material-specific collection and handling because accumulated combustible-metal fines can present a Class D fire hazard. Review filtration media, collection, and disposal procedures with the facility's EHS team.

Application review

Aerospace system selection depends on coolant type, processed materials, contaminant load, required flow, machine layout, and finish requirements. EdjeTech engineers review these operating requirements and recommend the appropriate system configuration.

Application questions

Aerospace coolant-management considerations

  • 01

    What filtration does titanium grinding need?

    Paper-bed media captures titanium and other non-ferrous alloy fines at a rating selected for the coolant, wheel, and surface-finish specification. Magnetic separation applies only when the process also produces ferrous material. Add coolant recycling when tramp oil, concentration, consumption, and disposal also require control.

    Grinding coolant filtration →
  • 02

    Why does titanium need reliable fines removal beyond part quality?

    Fine titanium particles can present combustible-metal fire or explosion hazards depending on particle size, form, concentration, and operating conditions. Filtration and collection methods should be reviewed with the facility's EHS and fire-protection teams. The facility must determine the waste classification and disposal requirements for collected fines and loaded filter media.

  • 03

    What size system fits a small captive aerospace shop?

    C.R.O.S.S. models process approximately 2 to 25 GPM and can use portable dirty-coolant transfer where central piping is not practical. Final sizing follows coolant volume and required throughput.

    See C.R.O.S.S. →
  • 04

    Can EdjeTech review the application before quotation?

    Yes. EdjeTech can review the fluid, materials, contaminants, required flow, finish specifications, and facility layout before recommending equipment.
