Water jet cutting of alumina ceramic substrates for firing setters.

With our extensive experience and track record in water jet cutting, we accept requests for prototyping and verification cutting of difficult-to-process materials such as metals, plastics, and composites.

The firing process is diversifying to meet various needs. We accommodate custom specifications for electric furnaces beyond standard sizes. Plates with an alumina (Al2O3) purity of 99.5% or higher are industrial materials with excellent heat resistance, hardness, and electrical insulation properties. Due to their hardness and brittleness, a different approach is required compared to general metal materials, which may involve diamond saws or special electrodes for wire electrical discharge machining. However, considering factors such as thermal impact, cost, delivery time, and processing accuracy, water jet cutting was chosen. First, we conducted a test cut just to be safe; although a tapered cross-section was produced, we determined that cutting was feasible and officially accepted the order.
