Sintering refers to a process in which powdery materials are transformed into dense bodies, and is a very important step in the production process of cemented carbide. The cemented carbide sintering process can be divided into four basic stages: removal of forming agent and pre-sintering stage;

Like tungsten-cobalt alloys and tungsten-titanium-cobalt alloys, tungsten-titanium-tantalum (niobium)-cobalt alloys are also commonly used hard alloys. These alloys are also known as tungsten-titanium-tantalum (niobium)-cobalt alloys because of their excellent physical and chemical properties and strong versatility.

Cemented carbide inserts are mainly made of solid carbide as the matrix through multiple production processes. They have high hardness, wear resistance, good toughness, heat resistance and corrosion resistance. The choice of cemented carbide blade grades should be based on requirements.

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.
