Alumina Ceramic Machining
Alumina ceramics are produced through methods such as injection molding, die pressing, isostatic pressing, slip casting, and extrusion. After sintering and densification, machining requires diamond grinding techniques. Advanced Ceramic Hub utilizes cutting-edge green and biscuit machining technology to produce more complex components with traditional methods. Our advanced machining center includes drilling, grinding, milling, polishing, sawing, tapping, threading, and turning, enabling the manufacture of alumina ceramic components with tight tolerances and high complexity. During the machining process, 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
The Alumina Ceramic products are carefully placed in wooden cases or cartons with additional support from soft materials to prevent any shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
