Carbide Cutting Tools Wear Reasons

Carbide cutting tools wear mainly include abrasive wear, adhesive wear, abrasion and chemical diffusion wear those four categories, reasons of carbide cutting tools wear are as follows:

1.Abrasive wear. When cutting, the chips, the workpiece material is contained in some of carbides, oxides and hard particles BUEdebris that can scratch the surface of carbide cutting tools, this is the abrasive wear (also called hard particle abrasion).

2. Adhesive wear. Present on the surface of the particles of carbide cutting tools and chip or relative movement of the workpiece is taken away, the bonding tool wear occurs.

3. Diffusion wear. In cutting temperature, carbide cutting tools and workpiece surface, formed by a fresh surface chip always contact the tool and the workpiece in the chemical elements, the chip chemical elements are mutual diffusion occurs, the performance of the carbide cutting tool materials decline, accelerated tool wear.

4. Chemical wear. When the temperature conditions are met carbide tools to work with some of the surrounding medium chemical reaction occurs in the processing environment, if there is some kind of corrosive media, the tool will cause corrosion, the formation of the tool wear.
