JB/T 15437.1-2026CNC gear milling machines of fine-modulus spiral bevel gear - Part 1: Testing of the accuracy (English PDF)

JB/T 15437.1-2026 is the English-translated version of 数控小模数螺旋锥齿轮铣齿机第1部分：精度检验.

This part of the series on CNC gear milling machines for fine-modulus spiral bevel gears deals with the testing of accuracy. It sets out the method for checking the accuracy of numerically controlled machines that mill spiral bevel gears of small module, and serves as the inspection reference for this machine type.

It is used by machine tool manufacturers for final inspection, by buyers who run acceptance tests, and by laboratories that verify machine accuracy. Part 2 of the series covers the specification of the machine. JB/T 15437.1-2026 is a voluntary industry standard (JB/T), issued by the Ministry of Industry and Information Technology on 28 April 2026 and effective from 2 November 2026. It is a new standard.
