The invention discloses an efficient high-precision magneto-rheological polishing device for ceramic balls. The efficient high-precision magneto-rheological polishing device comprises an outer ring barrel (1). An inner ring sleeve (2) is arranged inside the outer ring barrel (1) and internally provided with a magnet (6). Multiple retainers (4) are arranged at the outer diameter of the inner ring sleeve (2) and provided with ball containing structures (3). The portions between the outer ring barrel (1) and the retainers (4) and the portions between the inner ring sleeve (2) and the retainers (4) are each provided with a magneto-rheological polishing space (10). The ball containing structures (3) are arranged to communicate with the magneto-rheological polishing spaces (10). A magneto-rheological polishing solution filling the efficient high-precision magneto-rheological polishing device can generate magneto-rheological polishing pads (5) which can achieve self-sharpening to replace abrasive particles, so that the ceramic balls in the retainers (4) are polished; the efficient high-precision magneto-rheological polishing device is simple and compact in structure, low in cost and highin machining efficiency; and the super-precision ceramic balls high in surface quality and shape precision and free of subsurface damage can be obtained.
Description
technical field [0001] The invention relates to a ceramic ball grinding and polishing device and a polishing method thereof, in particular to a processing device for precision grinding and polishing of high-precision ceramic balls in high-speed, high-precision ceramic ball bearings, which belongs to the processing technology of high-precision spherical parts. Background technique [0002] With the rapid development of the industrial level, the requirements for the accuracy and reliability of machine tool equipment and working instruments are getting higher and higher. Compared with traditional metal materials, high-precision advanced ceramics have the characteristics of high strength, large elastic modulus, high temperature resistance, high pressure resistance, wear resistance, low thermal expansion coefficient, good thermal stability and chemical stability, etc., in ball bearings It is used extensively and is its key part. At the same time, ceramic balls play a very import...
