Machinable ceramics are ceramic materials that can be processed using ordinary mechanical processing methods. Industrial ceramics usually have the characteristics of high hardness and brittleness, making them very difficult to machine. In this environment, machinable ceramics have emerged. So what are the processing methods for machinable ceramics?

1. Mechanical processing

Mechanical processing is a traditional processing technology for ceramic materials, and it is also the most widely used processing method. Mechanical processing mainly refers to turning, cutting, grinding, drilling, etc. of ceramic materials. Its process is simple and processing efficiency is high, but due to the high hardness and brittleness of ceramic materials, mechanical processing is difficult to process engineering ceramic components with complex shapes, high dimensional accuracy, low surface roughness, and high reliability.

2. Electrical discharge machining

Discharge machining is a non-contact fine thermal processing technology, which first uses the mold and processing components as the anode and cathode of the circuit, and uses liquid insulating dielectric to separate the two poles. Through the etching effect of high-energy plasma suspended in the dielectric, the surface material is melted, evaporated, or thermally peeled off to achieve the purpose of processing the material.

3. Ultrasonic machining

Ultrasonic (vibration wave with a frequency exceeding 16000 times per second) machining is the use of tools (molds) that generate ultrasonic vibration to drive abrasive suspensions between tools and ceramic components, impact and polish components for machining. Due to the small force exerted on the components during the processing, the material surface generates less mechanical stress, resulting in less damage to the material and better surface roughness. Ultrasonic machining is suitable for processing hard and brittle materials with complex shape requirements and non-conductive properties.

4. Laser processing

Laser processing is the use of a high-energy density uniform laser beam as a heat source to generate instantaneous high temperatures at local points on the surface of ceramic materials, which are melted or vaporized to remove the material. Laser processing is a non-contact and frictionless processing technology that does not require molds during the processing. By controlling the focusing position of the laser beam on the surface of ceramic materials, it can achieve the processing of three-dimensional complex shaped materials.
