3 Terms and Definitions
The following terms and definitions apply to this standard.
3.1
By plane table axis and the tool spindle axis.
3.2
And the plane perpendicular to the longitudinal plane.
4 General requirements
4.1 When using this standard, shall GB/T 17421.1-1998 relevant provisions, in particular installation, spindles and other precision test portion before
Member of the warmed air operation, the accuracy of testing methods and testing tools.
4.2 according to GB/T 17421.1-1998 3.1 installed in horizontal adjustment of the machine, the vertical and horizontal level meter readings should not exceed
0.04/1000.
4.2.1 For table feed machine, on the machine table to put a special gages, across the center of the table to make it, put two water gages on
Level meter, a longitudinal plane parallel to a transverse plane parallel to adjust the level of machine installation. In the seizure of the work surface does not move
Case, the table rotates 180 ° so that the same test once again. Two horizontal instrument readings were calculated, the algebraic sum of the two measurements of the half,
Namely as the installation level in both directions.
a) Maximum workpiece diameter machine ≤500mm. The table in the middle of all stroke adjustment;
b) Maximum workpiece diameter > 500mm machine. table located at both ends and the middle of all stroke adjustment.
4.2.2 For the column feed machine, put a special gages on the rail bed, put in two horizontal instrument gages on a level with the longitudinal plane
OK, a parallel to the transverse plane, gages located at both ends of the rail bed, adjust the installation level, while adjusting horizontally mounted on the machine table.
The accuracy of test items 4.3 standard listed in the order, the order does not indicate the actual test. In order to test tools and test assembly and disassembly convenient,
