Measurement of the center diameter of the circular arc groove in the hole

When processing the circular arc groove d in the outer ring of the slewing ring as shown in Fig. 1, since the annular oil groove is extremely difficult to measure in the middle of the circular arc groove d, the dimension D_0 is difficult to ensure during the turning process, and the workpiece repair rate and scrap rate are high. Both are very high. Through work practice, we have explored a set of more scientific measurement methods, which is time-saving and convenient, and is very popular among operators. When turning, first strictly control the size of the hole diameter D_1, and then put it into a standard steel ball with a diameter of 20mm during the measurement.

Short-wave Pass Linear Gradient Filter

The short-wave pass linear gradient filters are continuously coated to achieve spatially continuous variation of filtering characteristics based on a multi-layer wedge-shaped film structure. The slope of the film can be adjusted according to the dispersion requirement to obtain the target linear rate of change. The Linear Gradient Filter is highly integrated and has an irreplaceable advantage in the miniaturization and lightweight design of spectroscopy instruments. The products are widely used in lightweight hyperspectral imaging spectrometers, portable spectrometers, and medical endoscopes.
