Method for measuring the center distance of two holes

Figure 1 shows a screw compressor body produced by our factory in small batches. According to the technical requirements, two yin and yang rotor holes φ134.4_(+0.12)~(+0.15)mm and φ115.2_(+0.12)~( The center distance of +0.15)mm is 96mm±0.02mm. Because the matching gap between the yin and yang rotor and the two holes is relatively precise, each measurement is required in the production process.
