Embodiment

[0061] When the reference speed of the polishing disc is C=150rpm, set T1 to f 1 =10mm / min, a p1 =10μm, w c1 =(r-r 0 )*0.2, T2 is f 2 =3mm / min, a p2 =10μm, w c2 =0, the measurement results after turning the disk are as image 3 As shown, the disk surface shape ( figure 2 ) And the disk shape under T1 conditions ( image 3 a), C can be introduced F Is 47. Similarly, compare the shape of the disk under T0 condition ( figure 2 ) And the shape of the disk under T2 conditions ( image 3 b), C can be introduced t Is 92, and then the compensation speed w at the reference speed C can be calculated 3 , The rotating speed of the polishing disc when implementing variable speed turning is as Figure 4 As shown, the radial profile error of the polishing disc after variable speed turning is about 0.8μm, such as Figure 5 Shown.

Abstract

The invention provides a precision turning method for a metal tin polishing disc. According to the precision turning method for the metal tin polishing disc, during turning, the turning tool feeding speed and cutting depth are kept unchangeable, the rotation speed changes of the polishing disc are controlled for compensation, the stable temperature field is achieved, and the height of a tool noseis kept unchangeable. In the turning process, the rotation speed changes of the polishing disc are controlled, in other words, constant temperature field control in the turning process is achieved through rotation speed compensation, and accordingly the flat tin polishing disc is obtained. By means of the precision turning method, rapid correction of planeness of the metal plane polishing disc canbe achieved, the turning requirements for different sizes of polishing discs can be met, the operation process is simple, and universality is good.

Description

Technical field [0001] The invention relates to the technical field of optical processing, in particular to a precision turning method of a metal tin polishing disc. Background technique [0002] With the continuous development of laser technology, hard and brittle optical materials have more and more important application space, such as YAG slab elements in solid-state lasers, sapphire screens, etc. These hard and brittle materials have high hardness and are chemically inert. Traditional polishing methods have the problems of poor surface quality and low processing efficiency. In order to ensure the qualification rate, processing efficiency and processing cost of hard and brittle material components, it is very important to select reasonable polishing process parameters. The tin metal composite polishing disc is a suitable hard and brittle material polishing mold. The tin composite disc has the appropriate hardness, which can make the hard and brittle material obtain a higher s...
