Zirconia Ceramic Machining
Zirconia, a high-performance ceramic, is known for its toughness, hardness, and wear resistance, making it ideal for applications requiring high mechanical strength and thermal stability. However, machining zirconia can be challenging due to its hardness and toughness, requiring different methods depending on its processing state.
Machining Zirconia in Different States:
- Green and Biscuit Form: Easier to machine before sintering, but tight tolerances can’t be maintained due to shrinkage during sintering.
- Fully Sintered Zirconia: Becomes hard and dense, requiring diamond grinding or cutting for precise shapes.
Common Machining Methods:
- CNC Machining: Used for complex shapes, often with diamond tools.
- Diamond Grinding: For precise dimensions and surface finish.
- Diamond Cutting and Sawing: Special diamond tools prevent cracking.
- Polishing: Smooths surfaces, especially for medical or precision applications.
Zirconia Ceramic Packaging
Zirconia 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.
