Cemented carbide is the most widely used type of high-speed machining (HSM) tool material. This type of material is produced by powder metallurgy, and consists of hard carbide (usually tungsten carbide WC) particles and a softer metal bond composition.

Appears along the edge of the pressure block, and is at a certain angle to the pressure surface, forming a neat interface called delamination. If the cobalt content of the mixture is low, the carbide hardness is high, the powder or granules are finer, the forming agent is too small or unevenly distributed, the mixture is too wet or too dry, the pressing pressure is too large, and the unit weight is too large. Layered. Improving the strength of the briquettes, reducing the internal stress and elastic aftereffect of the briquettes are effective methods to solve the delamination.

Want to be applied to high-performance, high-precision CNC machine tools, while achieving stability and better processing efficiency, generally put forward higher requirements than ordinary tools for carbide CNC tools from design to manufacturing and use.

The cemented carbide is made of tungsten carbide powder as a matrix, and is pressed and sintered with cobalt powder as a binder. Usually contains 94% tungsten carbide and 6% cobalt. Because of its high hardness, it is very wear-resistant and has a certain strength, suitable for high-speed cutting.

The main problem that may occur during the milling process is the possibility that chips may choke the tool. If a milling cutter is finally choked, it cannot carry out chips any more and the feeding force of the spindle will break it.

Designing for Carbide Designing for Carbide requires special considerations in the area of selecting safety factors based on stress, toughness, impact and corrosion characteristics. Components should be designed within these parameters for optimum performance.

The hardness of the metal is the ability of the metal material to resist local deformation, especially plastic deformation, indentation or scratching. It is an indicator to measure the degree of softness and hardness of the metal material.

The cemented carbide pulse nozzle is based on the principle of self-oscillation, relying on the self-oscillation chamber of the nozzle itself to convert the continuous jet into a pulsed jet, that is, the jet flows into the water chamber from the different flow in the upper section of the nozzle

Cemented carbide forging die is also called forging die. It has good heat resistance and fatigue resistance. It applies a certain pressing force through the closing and closing of the upper and lower dies, so that the forgings have better structure and mechanical properties.

Metal hardness is ability of a metal material to resist local deformation, especially plastic deformation, indentation or scratching. It is an indicator of the hardness of a metal material. It can sensitively reflect the chemical composition, metallographic structure, Differences in heat treatment.
