There are white stains on the processed surface! There were no defects due to discoloration or stains, and difficult-to-cut materials were processed without any issues.

We would like to introduce a case where the selection of suitable oils resolved discoloration of aluminum materials for our customers in Niigata Prefecture's optical equipment manufacturing. The company was using a water-soluble cutting oil recommended for aluminum processing of aircraft parts, but faced the issue of white stains appearing on the machined surfaces of the parts. Immediately after switching to a new cutting oil, and while continuing machining as usual for a while, there were no stains on the processed aluminum parts, resulting in zero defective products. 【Case Summary】 ■Challenge - Used water-soluble cutting oil recommended for aluminum processing, but white stains appeared on the machined surfaces of the parts. ■Implementation Effect - No stains appeared on the processed aluminum parts, achieving zero defective products. *For more details, please download the PDF or feel free to contact us.
