Water-jet cutting of Zerodur

[daveykbelgium]

Hello

I want to reduce the manufacturing cost of a batchof different zerodur part which are about 500mm square, and 200mm deep. Presently the components are only ground on a 5-axis machining centre, but in two completely seperate operations - rough-machining and fine-machining.

I have read about water-jet cutting of zerodur and see that it it technical feasible with little or no compromise, widely performed, fast, and induces far less residual stress than grinding.

My questions relates the availablity of machininst in Europe - whether there are combined water-cutting and milling machines because some features can't be made with water-jet cutting - and finally, is anybody aware of tooling concept for zerodur that doesn't involve gluing to a tooling plate?

Thanks in advance

Dave
