Common methods for alumina wear resistant ceramics processing

Common methods for processing alumina wear resistant ceramics shared by Chemshun Ceramics factory , welcome to check 

Dry grinding: This method uses grinding tools to cut Chemshun alumina ceramics, but attention should be paid to the control of grinding pressure and temperature to avoid surface cracks or breakage.

Wet grinding: Coolant is used during the grinding process to reduce the temperature, play a lubricating role, and reduce the impact of grinding force on ceramics.

Ultrasonic machining: Cutting using ultrasonic vibration can effectively reduce the impact of grinding force on ceramics, but special ultrasonic machining equipment is required1.

Laser machining: Cutting or drilling using laser beams has the advantages of high precision and no pollution, but professional laser machining equipment is required.

Cutting: Use high-speed cutting technology to process the blank into the desired shape.

Grinding and drilling: Use grinders, wire cutting and other equipment for fine machining to achieve the desired size and shape.

Specific steps in the processing process include:

Raw material preparation: Alumina powder is mixed with additives (such as titanium oxide, yttrium oxide, etc.), a wetting agent (such as glycerol) is added, and pressed into a blank.

Sintering: The blank is sintered in a high-temperature sintering furnace to form a dense body.

Rough machining: The sintered ceramic block is processed into the required shape by sawing, milling, turning, etc.

Fine machining: Use grinding machines, wire cutting and other equipment for fine machining to achieve the required accuracy and surface finish.

Coating: Wear resistant coatings such as titanium nitride and silicon carbide are applied to the surface to improve wear resistance.
