JB/T 15623.2-2026 is the English-translated version of 数控双面落地铣镗床第2部分：技术规范.

JB/T 15623.2-2026 is Part 2 of the series on CNC double side floor-type boring and milling machines and gives the technical specifications for this type of machine tool. It applies to the machine as a manufactured product within the field of metal cutting machine tools, a computer numerically controlled machine used for boring and milling work.

The part is useful to machine tool manufacturers who design and build these machines, to heavy-industry users that purchase and commission them, and to test laboratories and inspectors who check machines against agreed technical provisions. Its code carries the letter T, so it is a voluntary (recommended) standard and not a mandatory one. It was issued by the Ministry of Industry and Information Technology on 1 June 2026 and takes effect on 1 December 2026. It does not replace an earlier edition. The full English translation lets foreign machine builders, importers and buyers read the Chinese provisions directly when specifying or accepting such machines.
