ceramic parts
Ceramic parts customized machining ceramic structure components
Structural ceramic parts have superior strength, hardness, insulation, thermal conductivity, high temperature resistance, oxidation resistance, corrosion resistance, wear resistance and other characteristics, showing high stability and excellent mechanical properties under very harsh environmental or engineering application conditions. Especially in the environment of mechanical components or electronic components with high precision, high wear resistance and high reliability, structural ceramic parts are more efficient and longer in use than parts of other materials, and structural ceramic parts are more time-saving and cost-saving.

Ceramic parts machining process
The machining process of ceramic parts mainly includes three stages: roughing, semi-finishing and finishing.
- 1. Roughing stage: The use of milling, turning and other traditional machining methods to remove most of the margin, so that the parts close to the final shape. Due to the hardness and brittleness of ceramic materials, it is necessary to select the appropriate tool and cutting parameters during roughing to avoid tool wear and parts breakage.
- 2. Semi-finishing stage: on the basis of rough machining, further adjust the shape and size of the parts. At this stage, grinding, grinding and other methods can be used to obtain higher surface quality and accuracy. At the same time, it is also necessary to pay attention to controlling the machining temperature and the use of coolant to prevent the generation of thermal deformation and cracks in the material.
- 3. Finishing stage: After the shape and size of the parts are basically determined, finishing is carried out to improve the surface quality and accuracy of the parts. Finishing methods include ultra-fine grinding, polishing and grinding. At this stage, special attention needs to be paid to the selection of tools during machining, the adjustment of cutting parameters and the control of the machining environment to ensure the machining quality and efficiency of the parts.
