Carbide rotary files classification and selection of surface coatings

- Apr 17, 2019-

There are many factors that need to be considered in the manufacturing process of carbide rotary files.
In the production process of carbide rotary file, in order to further improve the service life of the tool, it is usually necessary to choose a surface coating on the tool. The surface coating can not only reduce the chip removal performance, but also extend its service life.
The surface coating of carbide rotary file is usually divided into the following types: titanium carbide coating, titanium aluminum oxide coating, titanium oxide coating and diamond-like coating.
For titanium oxide coating, it belongs to high wear resistance and high hard coating, the hard alloy rotary file of oxidation resistance wear and chemical stability is better. This tool is suitable for cutting high alloy steel and stainless steel and other workpieces. For titanium oxide coating is mainly suitable for processing rust iron parts and steel parts, etc., this coating is more general coating, can reduce the friction coefficient of the tool surface in the process of use.
For diamond-like coating, this coating has high hardness and excellent wear resistance. This coating has strong combination with the body and excellent corrosion resistance. It is suitable for processing aluminum alloy and other non-ferrous metals.
A correct understanding of the surface coating of carbide rotary file is helpful to the selection of cutting tools.
