What is Green Machining Ceramics?
International Ceramic Engineering provides cutting-edge ceramic parts manufacturing and machining services. We specialize in machining components before sintering, to ensure superior accuracy and performance, and to save money. (MACHINING IT GREEN).
Why? Ceramics are harder than tool steel, so grinding and machining a hardened part takes a lot of time and tool wear.
By machining the parts in the pre-hardened state, we can easily add features and dimensions in a tenth of the time. In fact we can add features to your parts that can’t be made any other way.
This method of ceramic manufacturing allows us to create and deliver high-quality, high-precision parts in custom geometries. Our machining process reduces the amount of time and effort needed to achieve the desired precision, making it the most efficient option for ceramic parts manufacturing.
