Bijoy Bhattacharyya, Biswanath Doloi, in Modern Machining Technology, 2020. 5.1.5 Chemical milling. Chemical milling is the subtractive machining process using baths of temperature-regulated etching chemicals to remove material for producing the required shape [11].It is defined as the method of chemically corroding of material to produce blind features like pockets, channels, etc.

Etching titanium with HF and nitric acid blends produces hexafluorotitanic acid, nitrogen dioxide, and water. With this solution, the HF tends to be more stable, the hydrogen gas is eliminated, and the etch rate increases. We offer different chemical concentrations of N+HF blends based on the required specification or on the desired effects of on the etch rate and surface finishes.
