Preliminary Chip Removal
The machining process generates a significant amount of chips on form cutters; therefore, the first step is to thoroughly clear the chips from between the cutter teeth using a soft-bristled brush, an air gun, or a plastic scraper. Strictly avoid using stiff metal brushes or sharp tools, as these may scratch the surface of the teeth or compromise the precision of the tooth profile. This preliminary cleaning should ideally be performed while the tool is still slightly warm, as this makes chip removal easier; however, exercise caution to avoid burns.
Oil and Contaminant Removal
During machining, the tool surface inevitably accumulates cutting fluids or machine oil, necessitating cleaning with a specialized cleaning agent or anhydrous alcohol. The tool may be soaked in a mild cleaning solution for a few minutes, after which a soft cloth or cotton swab should be used to meticulously wipe down every tooth and groove on the cutter body, ensuring the complete removal of oil residues, metal fines, and residual cutting fluids. For stubborn stains, the soaking and gentle scrubbing process may be repeated, though care must be taken to avoid applying excessive force.
Drying and Rust Prevention
Once cleaning is complete, the tool should be dried using compressed air or thoroughly wiped down with a clean cotton cloth to ensure that no moisture remains on the surface. For form cutters made of high-speed steel-which are prone to rusting-a thin protective layer of rust-inhibiting oil should be applied to prevent oxidation and corrosion. After cleaning, it is best to store the tool in a dry, dust-free tool case or rack to prevent accidental contact with other metal tools, which could result in damage to the cutting edges.
