Abrasive water jet turning is a reducing technology that uses a high pressure water jet with granules - read: ‘abrasive’ - particles. How does it actually work? Water and particles are mixed together to become a high pressure water jet in the spray nozzle. Next the combined translatory movement of the water jet and the rotating movement of the work piece ensure that cylindrical shapes can be processed.
Grinding through electrolytic in-process dressing (or ‘ELID’ for short) is an efficient technique for processing extremely hard and brittle materials such as ceramics (ZrO2, Si3N4), cermets and hardened steel. This grinding technique allows metal-bound grinding discs to be used, which are after all highly durable and difficult to adjust compared with discs with resins or glass. Moreover, ELID grinding allows a work piece with good geometrical accuracy in combination with a highly smooth surface to be obtained, making a polishing stage redundant.
