Corrosion-resistant tool for machining in liquid

Abstract

The invention discloses a corrosion-resistant tool for machining in liquid, which comprises a tool holder and a tool edge. The corrosion-resistant tool is characterized in that the tool holder is provided with a bolt hole, corresponding surface treatment is respectively performed for the bolt hole and the tool edge, and the surface treatment refers to anodic oxidation or micro-arc oxidation, so that corrosion is avoided during cutting in the liquid with pH (potential of hydrogen) ranging from 4 to 10.

Description

technical field

[0001] The invention relates to a cutting tool for machining, in particular to a corrosion-resistant cutting tool for machining in liquid. Background technique

[0002] Cutting tools are the most widely used tools in the field of mechanical processing, and there are many processing and manufacturing methods for them. Chinese patent publication CN00104139A discloses a method for surface treatment of cutting tools, which uses a filtered cathode arc plasma source to deposit an amorphous diamond hard carbon coating on the blade, and deposits an amorphous diamond hard carbon coating on the sharp edge of the substrate. The diamond coating contains at least 40% by volume carbon bonds, has a hardness of at least 45 GN / m2, and a modulus of at least 400 GN / m2. The aforementioned substrates can be mechanically ground without an intervening layer between the substrate and the amorphous diamond coating. The aforementioned coatings give thin blades rigidity and toughness...
