A strong confinement flow controllable polishing device

Abstract

The invention discloses a novel powerful confinement flow controllable polishing device which comprises a nozzle sheath moveable mechanism, a gap control mechanism, a grinding particle flow input base, a pre-pressing system and a fixing plate, wherein the nozzle sheath moveable mechanism is mounted on the fixing plate which is vertically arranged through a straight line bearing; the grinding particle flow input base sleeves the nozzle sheath moveable mechanism and is fixedly mounted on the fixing plate through a fixing bolt; the pre-pressing system is mounted on the top of the nozzle sheath moveable mechanism; the gap control system is used for monitoring the moving distance of the nozzle sheath moveable mechanism; the nozzle sheath moveable mechanism comprises a grinding particle flow straight tube, a nozzle and a nozzle sheath which are arranged vertically. The novel powerful confinement flow controllable polishing device is simple and compact in structure and low in production cost, the surface of a workpiece to be processed is processed by using powerful confinement flow, and the problems that a jet flow beam is dispersed, impact damage can be caused and the like in grinding material jet flow polishing are avoided, so that not only is a relatively high material removing effect achieved for the processed workpiece to be processed, but also the processed workpiece is very good in surface processing quality.

Description

technical field [0001] The invention relates to the field of polishing, in particular to the field of jet polishing of strongly restricted abrasive flow, in particular to a controllable polishing device of strongly restricted abrasive flow. Background technique [0002] Hard and brittle materials such as optical glass and engineering ceramics have excellent mechanical properties such as high hardness, good wear resistance and corrosion resistance, and unique optical properties, so they are widely used in various fields, but their processing accuracy and surface quality requirements are also higher. More and more strict, the ultra-precision machining technology of hard and brittle material parts has become one of the urgent needs and the most challenging processing technology fields. The traditional mechanical polishing method has obvious defects in the controllable removal of materials, surface damage and processing efficiency. It is difficult to meet the processing requirem...
