Embodiment 1
[0033] Such as Figure 1-Figure 5 As shown, the present embodiment provides a processing method of an aspheric cylindrical mirror, and the equipment used is a two-axis ultra-precision machine tool. The two-axis ultra-precision machine tool has two ultra-precision linear axes X-axis and Z-axis. Cutter 2 is installed on the machine tool spindle 1 of lathe, and the preferred cutter head of cutter 2 is the diamond cutter of circular arc in the present embodiment; Specifically comprises the following steps:
[0034] Step S01, such as figure 1 As shown, a rough adjustment displacement platform 4 and a fine adjustment displacement platform 5 are placed on the machine tool table 3, and the fine adjustment displacement platform 5 is placed on the coarse adjustment displacement platform 4. By making the lower surface of the coarse adjustment displacement platform 4 close to the upper surface of the machine tool table 3, and the lower surface of the fine adjustment displacement platform...
Embodiment 2
[0041] Such as Figure 6 As shown, on the basis of the first embodiment, step S06 is further included, and step S01 to step S05 are repeated in the Z direction, so as to obtain the processing of the aspheric cylindrical mirror array.
[0042] Through the above method, not only the processing of the aspheric cylindrical mirror array with large depth-to-diameter ratio and processing depth greater than the Y-axis range is realized, but also the consistency of the array is high, so that a high-precision aspheric cylindrical mirror array can be obtained.
