3 General requirements
Veneer circular saw
General rules for machine tool inspection
Part 1: Geometric accuracy of machine tools under no-load or finishing conditions 3.1 When using this standard, reference must be made to GB/T17421.1, especially the installation before accuracy inspection, the idling temperature rise of the spindle and other components, the inspection method and the accuracy of the inspection tools.
3.2 Adjust the installation level of the machine tool in accordance with 3.1 of GB/T17421.1—1998. The readings of the level in both the longitudinal and transverse directions shall not exceed 0.04/1000.
3.3 When the actual measured length is different from the measured length specified in this standard, the difference shall be converted according to the length that can be measured in accordance with the provisions of 2.3.1.1 of GB/T17421.1—1998. When the conversion result is less than 0.005mm, it shall still be calculated as 0.005mm. 3.4 During the inspection, the actual inspection sequence can generally be arranged according to the requirements of the assembly and disassembly inspection tools, inspection convenience and inspection items. 3.5 According to the agreement between the user and the manufacturer, the inspection items and inspection methods can be appropriately increased, decreased and adjusted.

Refer to the relevant provisions of GB/T17421.1-1998 5.6.1.2.2
Install the indicator on the fixed part of the machine tool so that its probe touches the surface of the spindle centering journal vertically. Rotate the spindle for inspection.
The maximum difference in the indicator readings is the radial runout error. The inspection should be carried out in the vertical axial plane and the horizontal axial plane through the axis.
5.6.3.1.1
Install the indicator on the fixed part of the machine tool so that its probe touches the outer edge of the end face of the positioning surface of the spindle flange vertically.
Inspect by rotating the spindle.
The maximum difference in the indicator readings is the end face runout error. 5.5.2.2.3
Install the special flange that replaces the circular saw blade on the spindle, and the indicator on the fixed part of the machine tool so that its probe touches the inspection surface of the special flange vertically. Adjust the flange so that the indicator readings are the same after it rotates 180 degrees with the spindle. The spindle box is tested by feeding motion. The maximum difference of the indicator reading is the verticality error. JB/T3364.2-1999 Test items: The axis of the test piece clamped in the vise is perpendicular to the feeding direction of the circular saw blade. The axis of the test piece clamped in the vise is perpendicular to the circular saw blade in the given plumb direction. ||Verticality of the rotating plane

Clamp the inspection rod with flange in a V-shaped vise, and install the indicator on the spindle so that its probe touches the flange end face of the inspection rod vertically. The spindle box makes a feed motion for inspection.
The maximum difference in the indicator reading is the verticality error. Clamp the inspection rod with flange in a V-shaped vise, and install the indicator on the spindle so that its probe touches the flange end face of the inspection rod vertically. Rotate the spindle and inspect in the vertical direction.
