This invention discloses a jet electrolytic machining device and method for surface microtexturing, specifically relating to the field of special machining technology. It includes a spindle with a nozzle connected to it. Both sides of the nozzle are connected to liquid inlet pipes. The nozzle contains a liquid collection chamber, the bottom of which is connected to a liquid delivery groove. A protrusion higher than the bottom of the liquid collection chamber is provided at the connection between the liquid delivery groove and the liquid collection chamber. The bottom of the nozzle has a honeycomb-shaped liquid outlet hole, which is connected to the liquid delivery groove. This invention solves the problem of low precision and quality in existing microtexturing machining, improving the machining precision and quality of mechanical components.

This invention relates to an ultra-low temperature ceramic binder, which is mainly composed of the following raw materials in the indicated mass percentages: Bi₂O₃: 40-80%, B₂O₃: 5-15%, ZnO: 10-35%, SiO₂: 0-5%, Li₂O: 0.5-3%, TiO₂: 0-5%, CaF₂: 2-10%, Y₂O₃: 0-5%. This binder can be fired at a minimum temperature of 400°C and softened at a minimum temperature of 320°C. It enables the ceramic binder to achieve bonding and consolidation before the polymeric pore-forming agent and temporary polymeric binder burn off, maintaining the integrity of the pore structure while achieving a high porosity. Furthermore, using this ceramic binder and a preferred polymeric pore-forming material, it is possible to construct spherical pores with interconnected microscopic gaps, and the pore size can be controlled during preparation.
