Perform according to the provisions of inspection method 4, sequence number 3 of JB/T2970
Put an inspection plate on the surface of the chain plate, and place the indicator on the plate. The meter contact
contacts the saw shaft element line, and detects several points from the shaft root to the shaft head. Then rotate the saw shaft
the main shaft axis line 90° to the chain surface
and repeat the above test. Record the parallelism of the guide ruler to the spindle centerline, the perpendicularity of the guide plate working surface to the worktable surface, and the reading difference at each measuring position (M1, M), calculated as follows: f(Mi-M2)max(Mi-M2)minl). Inspect the flat ruler close to the side of the guide ruler, extending it beyond the spindle. Fix the indicator on the spindle, rotate the spindle, and measure the point 250mm away from both sides of the spindle. Perform inspection according to the provisions of Article 3, No. 7 inspection method of JB/T2970. Note: "△" in the inspection diagram refers to the tolerance value of this item. 4.5.5 Working accuracy
The working accuracy shall comply with the requirements of Table 3.
