What are the main causes of wear of high speed steel cutting tools and carbide cutting tools?
Basically the same, such as plastic wear, flank wear, crater wear, chipping... And so on, each kind of wear phenomenon has the reason, also has some remedial or the improvement measure....High speed steel has lower hardness and abrasion resistance ability is not high, but good toughness, high precision of complex cutting tools, such as broach, gear cutter or the use of high speed steel more, while the standard NC tool are used in a lot of hard alloy or indexable tool..
There are two reasons1. The tool itself quality problems of our factory has been recommended 3-turn Kuwait this brand2. Just the material, good hardness of material, speed, feed, reduce the point properly, can protect the tool wear well
The tool wear mainly depends on the physical and mechanical properties and cutting conditions of cutting tools and materials. Under different conditions, tool wear has different characteristics. 1, hard point wear; 2, adhesive wear; 3, diffusion wear; 4, chemical wear;
(1) mechanical wear: the abrasion caused by the friction between the chip and the cutter front, the surface deformation of the workpiece and the sharp friction between the cutter face, called mechanical wear.When the cutting temperature is not too high, the mechanical abrasion caused by this friction is the main cause of tool wear.(2) thermal wear: when cutting, because of the severe plastic deformation and friction of metal, the cutting heat makes the blade hardness decrease, and the wear and tear caused by cutting performance is called thermal wear.It is recommended that the Santak wick tool be used to solve the wear problem.
