GB/T 25375-2010Metal-cutting machine tools - Check and evaluation for combine surface by miniating (English PDF)

3.1

two joint surface mating member (hereinafter referred to as bonding surface) contact quality inspection should normally be two joint surface directly combined research test.

3.2

joint surface can not be directly combined research test should be used when the gage were combined research test two joint surface. Such as two binding surfaces are flat, you should use

The same gage inspection; for dovetail shaped, rectangular, V-shaped, etc. by two or guideways with the above composition is particularly important or fixed joint surface,

Use sets of gage testing.

3.3

together with the seizure of research tests, gage length is generally not less than be replaced with the length of the member. Gage accuracy and technical requirements should be breaks

Together with the relevant provisions.

3.4

two direct bonding surface when combined research test, wherein a surface should achieve the required accuracy and technical requirements to the surface as a reference plane, another

Face as the mating surface. For guideways, the general should be chosen on the base member guide surface as a reference plane; for a machined surface to another

A combination of the two surface scraping surface, the general should choose the machined surface as a reference plane.

3.5

When using combined research medium for the red lead paint, its proportion by weight recommends the following.

Hongdan. L-AN Total loss system oil. kerosene ~100.7.3

Kerosene should be consistent with the provisions of GB 253 quality indicators.

Total loss system oil quality indicators should be consistent with the provisions of GB 443-1989 of L-AN32.

Red lead should be consistent with a primary or secondary quality indicators HG/T 3850-2006 requirements.

4.1 coating paint

4.1.1

The two joint surface directly combined research test, the combination of two such surfaces are machined surfaces or are scraping the surface, the coating may be applied to the reference plane

Or mating surfaces; such as the two combined have a surface to surface scraping, scraping paint should be applied to the surface.

4.1.2

Test with a gage surface machining, coating should generally be applied to the gage on. With the seizure test scraping surface, the coating should be applied to the scraping

Surface.
