Ceramics, including the dielectric material you're working with, are hard and brittle. This makes them difficult to cut without causing damage or inducing stress that could lead to cracks. However, several cutting techniques are commonly used with ceramics that can minimize these risks:
Diamond Saw Cutting: A diamond saw is a blade with diamond grit embedded in the edge. It's used to cut through hard materials like ceramics. It can offer a precise cut with minimal chipping, but care must be taken to avoid overheating, which can cause thermal stress and potential cracking.
Laser Cutting: Laser cutting is a non-contact process which is suitable for hard and brittle materials like ceramics. It can provide high precision and can minimize the risk of cracking or other damage. However, it can be more expensive than other methods and may not be suitable for all types of ceramic materials.
Waterjet Cutting: Waterjet cutting uses a high-pressure jet of water, sometimes with an added abrasive, to cut through materials. It's a good option for cutting ceramics because it doesn't generate heat, which can reduce the risk of cracking. However, it may not be as precise as diamond saw cutting or laser cutting.
Ultrasonic Machining: Ultrasonic machining uses high frequency, low amplitude vibrations to remove material, typically with the assistance of an abrasive slurry. This method is gentle and reduces the risk of cracking or chipping but may be less precise than others.
Each of these methods has its pros and cons, and the best method will depend on your specific requirements, including the size and geometry of the cuts you need to make, the acceptable level of damage or stress, and your available resources. Always take safety precautions when cutting any material, especially hard and brittle materials like ceramics.
The easiest and cheapest method, in my opinion, is the tile saws. They are made as wet and dry saws, meaning they use water to cool off and clean the surface or not. I had a great experience with them.
Generally, when cutting is peforming to the Hard-brittle materials; benefits would draw after ceramic is pre-conditioned in a choice of inert-liquid medium.
