Master Chemical has revealed that a British manufacturer of aircraft parts has improved production efficiency and increased sump life through the use of metalworking fluids such as Trim E708 soluble oil and Trim OG223 heavy-duty neat oil.

The manufacturer’s existing fluids were doing a good job but their supply involved multiple vendors and it was recognised that this was unwieldy from both an inventory and management point of view.

Master Chemical’s Trim E708 was trialled on Dugard machines to explore the product’s suitability. Trim E708 is a high-quality, universal soluble oil that requires minimal maintenance even in demanding fluid management systems. It has broad application scope in machining and grinding on a wide range of materials, and its stable and predictable performance makes it suitable for high-quality, consistent parts manufacture.

After the successful trial, Trim E708 was selected to replace the manufacturer’s existing fluid for general machining applications. Trim C115 was recommended for the dedicated grinding of cast iron and mild steels.

In addition, Trim OG223 — a medium- to heavy-duty neat oil — was proposed for selected turning applications. The final fluid — Trim RPO 6 rust-preventative oil — is a non-staining, water-displacing thin film that can be used on a range of materials.

Following the changeover, the aerospace manufacturer confirmed that the Master Chemical products met the performance standards required in terms of tool life and surface finish.

Key benefits of product application

  • Trim E708 meets the performance criteria set, including good corrosion protection for the machine and parts, good tool life, compatibility with several materials and low odour.
  • Trim C115 provides excellent coolant and chip setting, good tramp oil rejection and machine cleanliness, while leaving a protective film on the machine tool.
  • Trim OG223 is particularly good in high-pressure applications where low oil mist is advantageous. It conforms to the latest Chip 3 and aerospace regulations and therefore contains no chlorine or active sulphur additives.
  • Trim RPO 6 provides protection for precision parts during production and transit.
  • Completing the package, Master Chemical committed to monthly site visits to carry out coolant condition checks, report findings and make any recommendations for improvement.

The Coolant Management Company

Master Chemical develops and markets a comprehensive metalworking fluid
programme.  Its products are cutting and grinding fluids, cutting oils,
washing and cleaning compounds and rust preventatives.  They are all
marketed under the brand name, TRIM.

Since 1990 Master Chemical Europe has provided a dedicated sales and
manufacturing service for Europe.  In that time it has also become the
centre of excellence for product development to meet the specific production
needs of European manufacturers.

Its research has led to the introduction of a range of water- and vegetable
ester based formulations that are non-hazardous yet offer superb production

The need for this type of metalworking fluid is driven by EU regulation and
as a result Master Chemical Europe is now the leading manufacturer of
application-specific metalworking fluids.

When used in conjunction with Master Chemical’s trademark coolant management
strategies, these products provide optimum productivity and significant
operating cost reduction.

To provide greater capacity for this work the company recently moved to new
premises that include a laboratory that is three times bigger than its

Master Chemical Europe is now responsible for supporting an ever-expanding
distributor network, extending from Portugal in the south to Russia and
Scandinavia in the north and east.
