Title:
NANO-LAYER LUBRICATED DIAMOND GRINDING WHEEL GRINDING DEVICE BASED ON SHOCK WAVE CAVITATION EFFECT
Document Type and Number:
WIPO Patent Application WO/2022/052919
Kind Code:
A1
Abstract:
A nano-layer (41) lubricated diamond grinding wheel (20) grinding device based on a shock wave cavitation effect. The grinding device comprises a control system, an acceleration module, a shock wave speedup module, a machining module and a recovery module, wherein the control system controls the operation of the device; the acceleration module is composed of an acceleration tube (10), a small Laval tube (29), etc., and can make nanoparticles (11) obtain an initial speed; and the shock wave speedup module, which is composed of electromagnetic coils (13), shock heads (12), shock balls (16), wave collectors (18), large Laval tubes (19), etc., generates two wave sources, one being used for cleaning impurities on a surface of a grinding wheel (20), and the other being used for giving a shock to the nanoparticles (11), which have the initial speed, to the surface of the grinding wheel (20) to form a nano-layer (41). During a machining process, the nanoparticles (11) of the nano-layer (41) are autonomously released in a grinding core area, thereby realizing self-lubricating and cooling inside the grinding area; and the recovery module is used for recovering the nanoparticles (11), thereby realizing the reutilization of the nanoparticles.
