Description
Technical Field

Background
The polishing process is the only means for realizing ultra-precision size, ultra-accurate shape and extremely low surface roughness on the surfaces of various solid materials, and is also the best method for eliminating the processing defects and damages of materials below the surface layer. The polishing process has wide application range and can be used for ultra-precision processing of various complex molded surfaces. In particular to the processing of various complex-profile parts made of difficult-to-process materials used in the fields of optics and electronic information, the polishing processing technology plays an irreplaceable role.
The traditional polishing processing technology mostly adopts a low-speed processing mode of a loose abrasive, has the defects of low precision retentivity, low processing speed and the like, greatly influences the productivity of precision parts, particularly in the processing of large optical free-form surface parts, the grinding and polishing processing time accounts for most of the whole processing time, and the time for processing one product is less, hundreds of hours and more months.
For the slow annular grinding and polishing mode widely used at present, the motion mode is mostly the rotation of the grinding disc, the rotation and revolution of the workpiece relative to the grinding disc, although the process is relatively simple, the defects that the removal function is not ideal, the surface type of the workpiece is single, the workpiece is difficult to adapt to the processing of a complex curved surface, the size of the workpiece, the rotating speed of the workpiece and the rotating speed of the grinding disc are strictly limited, and the like exist; for airbag polishing equipment newly adopted abroad, the structure is complex, the abrasive particle turning radius on the ball-head-shaped polishing head is small, the grinding and polishing speed is low, the processing efficiency is not obviously improved, although the airbag polishing equipment is suitable for processing parts with complex profiles, the efficiency is low when large and medium ultra-precise parts are processed, and the processing cost is very high when the airbag polishing equipment is used.
The machining of ultra-precise free-surface optical elements requires control by deterministic polishing techniques, and the machining accuracy of optical elements using deterministic polishing control techniques is related to the depthwise function profile of the polishing tool used. The approximately Gaussian removal function with more intermediate removal can meet the technical requirement of deterministic polishing on ultra-high precision surface shape correction, in order to obtain the removal function of the shape, the axis of a polishing tool head and the normal of the surface of a workpiece are generally processed at a certain angle, and the removal function formed in the mode is low in center but not in rotationally symmetrical distribution. To obtain a rotationally symmetric removal function with a low center, the tool head is generally subjected to a compound revolution motion while rotating. The existing structure needs to use a rotary joint or a slip ring to transmit electric energy or substances in order to realize the function, and the rotary joint has lower bearing capacity on the rotating speed and pressure, so that the improvement of the processing efficiency is limited.
The invention discloses a spindle slewing device of an ultra-precision polishing machine for polishing wood, which is named as a spindle slewing device of the ultra-precision polishing machine for polishing the wood in China patent publication No. CN211220167U, published as 2020, 8, 11, and the application discloses a spindle slewing device of an ultra-precision polishing machine for polishing the wood, which comprises a polishing disk, a hydrostatic bearing mechanism, a motor and a motor base; the polishing disc, the hydrostatic bearing mechanism and the motor are sequentially installed and connected from top to bottom, and the motor is installed on the motor base; the motor base is of a flange type structure, the hydrostatic bearing mechanism is installed on the upper surface of a motor base flange, and the lower surface of the motor base flange is fixedly connected with the workbench.
