Machining of silicon nitride ceramic part
As far as the machining process of silicon nitride ceramic is concerned, it divides into cutting and grinding processing. Cutting processing involves accurate machining shape; however, it has high requirements for the accuracy of the machine tool. It’s important for a Silicon Nitride Ceramic Factory to maintain high-quality machining.
2.The characteristic of machining is that high dimensional accuracy can obtain after long-term processing. In a silicon nitride ceramic factory, precision is crucial for final product quality.
1) Ultrasonic processing of silicon nitride ceramic part
- Ultrasonic processing uses for processing round holes, shaped holes, cavities, and fine holes. It uses ultrasonic vibration tools where the tool and workpiece fill with diamond abrasive suspension. Through the ultrasonic vibration at the end of the tool, it causes impact damage of the processing surface. Silicon nitride ceramic factory might employ advanced techniques to enhance ultrasonic processing efficiency.
This method has the following disadvantages:
1.Processing tool replacement is more troublesome;
2.The quality of pro affect by factors such as the change of tool quality and the conduction of force;
2)Electrical processing of silicon nitride ceramic part
- EDM usually use for perforation molding and wire cutting. This process has the advantages of small workpiece loss. Moreover, it results in a small thermal influence on the workpiece surface. In the Silicon Nitride Ceramic Factory, new technologies continue to adapt EDM methods for better efficiency.
The conductivity of silicon nitride ceramics is weak, so EDM is generally not suitable. However, with the development of basic theoretical research and new technology, high-voltage EDM processing methods can also be used for silicon nitride ceramic materials. The development of new high-speed, high-precision EDM machine tools at home and abroad has aided this in recent years. Welcome inquiry.
