Case Studies

The aerospace components supplier encountered a problem controlling bacterial contamination in its metalworking fluid. This meant it had to conduct regular machine cleans of approximately two to three machines per month. It took half a day to clean and refill the machines and the lost machine time cost £65/ €71 per hour.

The existing metalworking fluid also periodically caused machining issues. The machines would tap oversize holes, which meant those component parts would have to be completely scrapped. Each scrapped component resulted in a £2,000/ €2,182 loss.

Weary of losing more money and productivity, the aerospace components supplier agreed to a six-week trial of TRIM™ E715, run at 6% to 10% concentration. TRIM E715 is a universal soluble oil that requires minimal maintenance and is suitable for machining aluminium, steel and nickel alloys, as well as cast iron and yellow metals.

The trial of TRIM E715 resolved the bacterial contamination issue completely, eliminating the need for costly cleanouts, a saving of nearly £8,000/ €8,730 per year. Resolving bacterial contamination also removed the bad odours that operators frequently complained about. All machines have since been switched over to TRIM E715.

TRIM E715 also fixed the issue with oversized holes that resulted in scrapped parts. The aerospace components supplier has had no reports of issues since the conversion.

And, as a bonus, several operators who suffered from dermatitis with the former metalworking fluid have had their skin clear up since the switch to TRIM E715.
