Alumina Ceramic Machining
Advanced ceramics are formed using methods such as injection molding, die pressing, isostatic pressing, slip casting, and extrusion. After sintering and densification, machining requires diamond grinding. Shanghai Yuepeng applies advanced green and biscuit machining to achieve complex shapes beyond traditional methods. Our machining center offers drilling, grinding, milling, polishing, sawing, tapping, threading, and turning, enabling the production of alumina ceramic components with high precision and complexity. During machining, the following precautions should be observed:
- Shrinkage Control: Alumina ceramics shrink by about 20% during sintering, requiring dimensional adjustments in the green body stage.
- Tolerance Control: Precise tolerances are unachievable in the green or pre-sintered state; fine machining should follow sintering.
- Diamond Grinding: Post-sintering, high-hardness alumina requires diamond grinding, as conventional methods fall short.
- Tool Selection: Diamond-coated tools or grinding wheels are essential to handle ceramic hardness and prevent tool damage.
- Temperature Control: Strict temperature management during sintering prevents cracking or deformation.
- Stress Management: Excessive stress during machining must be avoided to prevent brittle failure.
- Cutting Speed and Feed Rate: Controlled speeds and feeds ensure quality and extend tool life.
- Surface Treatment: Post-machining polishing removes defects, enhancing performance and appearance.
Alumina Ceramic Packaging
Alumina Ceramic products are typically packaged in vacuum-sealed bags to prevent moisture or contamination and wrapped with foam to cushion vibrations and impacts during transport, ensuring the quality of products in their original condition.
