Ceramic Materials

Ceramics vary in properties and quality. Manufacturers design different types of ceramics for specific applications, and choosing the right one is critical for precision machining. Here are some common ceramic materials used in CNC ceramic material machining:

  • 96% – 99.8% Alumina (Al203)
  • Aluminum Nitride (AlN)
  • Silicon Carbide (SiC)
  • Glass Ceramics
  • Macor
  • Porous Ceramics
  • Ferrites
  • Crystals Exotic
  • Technical Ceramics
  • ULE Glass Ceramic
  • Steatite
  • Silicon Nitride (SiN)
  • Black Ceramic
  • Many other hard materials

Matching processing techniques to your requirements

Elimold provides expert advice to our customers on the right type of material from aluminium oxide to silicon carbide, Macor®, borosilicate glass, soda lime and quartz. Always keeping your application and associated specific requirements in mind. Depending on the requirements and the desired surface roughness an optimum balance of precision CNC and polishing technologies is chosen. For more exact finishes, we rely on precise mechanical machining techniques such as micro-sandblasting, tribofinishing, micro-surface and etching technologies.

Engineered to the tightest tolerances

At Elimold we can meet the highest requirements when it comes to desired tolerances. We consistently measure and collect data during the manufacturing process (Q in process) rather than solely measuring and monitoring quality at the end of production. All of this is done, to ensure World Class Manufacturing processes that can run 24/7. This is crucial for many of the products we manufacture, including end effectors for wafer handling, wafer carriers and electron beam column components.

CNC Machining For Ceramics.jpeg

What is CNC machining of ceramics?

Ceramic CNC machining is a subtractive manufacturing process in which a machine controlled by computer commands uses a rotating cutting tool to shape a ceramic piece by removing material. It can be used to create precision ceramic parts with complex geometries. The process involves designing the part using CAD software, which is then converted into a machine-readable code.
The main benefit of using CNC machining in ceramic production is the ability to make complex shapes with amazing precision. The precision of the computer-controlled machines ensures consistent and accurate cuts as outlined in the design specifications. In addition, CNC machining is able to produce parts with a smooth surface finish, reducing or eliminating the need for additional polishing or finishing procedures.

Considerations for Designing Ceramics for CNC Machining

When working with ceramics, designers must consider certain factors before beginning the machining process. Prototyping is an essential step in the manufacturing process, especially for ceramic parts with complex designs. By creating a prototype, you can conduct extensive testing and evaluation before moving forward with large-scale production. This stage is essential for refining the design and making adjustments based on the prototype’s performance. Further recommendations for successful ceramic design include:

  1. Employ a modular approach in your design.
  2. Avoid clear sharp and elongated edges.
  3. Favor circular designs over oval shapes.
  4. Be mindful that sharp edges and corners can heighten the likelihood of breakage.
  5. Consider using corner pockets as a viable alternative to sharp corners, especially if avoiding rounded edges.
  6. In designs incorporating holes and slots, ensure they are adequately spaced to avoid crowding.
  7. Opt for simpler wall designs and shapes rather than complex ones.
  8. Avoid abrupt transitions in cross-sectional areas.
  9. Transform tensile stress into compressive stress, enhancing the ceramic material’s capacity to endure stress without cracking.
