GB/T 23575-2009Metal cutting machine tools - Check and evaluation for taper surface by miniating (English PDF)

3.1

conical surface in contact with the coloring method test should be used cone gauge (or similar accessory) combined research test.

3.2

test gauges should be used not less than GB/T 11852-2003, GB/T 11853-2003 and GB/T 11854-2003 regulation

Given tolerance class 2 cone gauge.

3.3

Technical requirements are the subject of the conical surface shall comply with the relevant standards and patterns.

3.4

coloring method test the conical surface of the contact, the use of red lead, Total loss system oil and kerosene mixed configuration made of red lead paint as a medium

Quality, which quality is as follows.

Hongdan. Total loss system oil. kerosene ~100.7.3

Hongdan quality indicators should be consistent HG/T 3850 in the coatings industry with red lead; Total loss system oil should be consistent with the provisions of GB 443 sticky

Grade of L-AN32 quality indicators; kerosene should meet the quality indicators GB 253 regulations.

It allows the use of red ink, pencils and other special red paint instead of mixing red lead paint. When assessing controversial conclusions should be mixed with red lead coating

The results of test materials as arbitration.

4.1

gauge conical surface and the subject should be cleaned, the coating is applied on the outer surface of taper gauge or seized parts. 120 ° apart in the mother

Line direction, three Tu Tu color line width of approximately 5mm; when the subject of more than 100mm diameter big end conical surface, allowing the bus separated by 90 °

Direction, four Tu Tu color line the same width. Paint should be applied evenly to a thickness of less than 2µm. Color layer coating thickness may be recommended in Appendix A

Simple method of determining judgment.

4.2

gauge (or similar parts) after being seized in conjunction with the conical surface, applying an appropriate axial force, so that combined research in close contact with the surface, after the relative rotation off open. Rotation angle of not more than 60 °, the rotation number no more than one round trip. It is approximately equal to the ratio of the length of the conical surface and seized big end or the small diameter of 1 […]
