5.1 Geometric accuracy inspection of machine tools
See Table 2 for geometric accuracy.
Inspection items
Inspection method
Touch the outer circumference of the roller with the dry meter contact, and measure the radial runout of the rubber coating roller.
Rotate the roller by hand, and the maximum difference in the readings is the measuring value.
Parallelism of the upper and lower rubber coating roller axes
Parallelism of the upper and lower movement of the rubber coating roller
5.2 Inspection of machine tool working accuracyWww.bzxZ.net
See Table 3 for working accuracy.
Inspection items
Evenness of glue coating
For a fixed value, at least three positions should be measured at the center and both ends of the roller
Move the spacing between the upper and lower glue roller shafts to the maximum, place a flat ruler in the vertical direction of the upper and lower roller shafts, and then place a precision level on it for measurement. The difference between the readings at the left and right ends of the roller shaft is the measured value
Use an internal micrometer to measure the distance between the two ends of the roller when the roller spacing is moved from zero to 20mm. The difference is the measured value
Inspection method
Overlap two veneers under the same conditions and pass them through the center and both ends of the glue roller at the same time, and measure the quality of each piece before and after glue coating. The difference between the maximum and minimum values ​​of the three passes is the measured value
5.3 The appearance quality shall comply with the provisions of Articles 4.11 and 4.12 of this standard. 5.4 No-load test
5.4.1 The machine tool should be ready for operation, and the operation start and stop should be carried out in accordance with the instruction manual prepared by the manufacturer. 5.4.2 Start and stop 10 times continuously to test the reliability of the action. 5.4.3 There should be no abnormal vibration after continuous operation for 1 hour. 5.4.4 No-load operation, the sound pressure level of the noise shall not exceed 75dB (A). 5.4.5 The electrical system should be safe and reliable when working. 5.5 Load test
15g/m2
QB/T 1528—1992
5.5.1 The load test can only be carried out after the no-load test is passed. 5.5.2 The test piece is taken from the same tree species, with a size of about 0.3m×0.6m, and the thickness and moisture content are uniform, and the surface is smooth. 5.5.3 The working accuracy of the machine tool shall be implemented in accordance with the provisions of Article 5.2 of this standard. 5.5.4 Load test is generally carried out in the manufacturer, and in the user's factory when necessary. 6 Inspection rules
