JB/T 15521-2026Sheet metal bending flexible processing unit (English PDF)

JB/T 15521-2026 is the English-translated version of 数控板料折弯柔性加工单元.

JB/T 15521-2026 covers the CNC flexible processing unit for sheet metal bending. Such a unit groups numerically controlled bending equipment into a flexible manufacturing cell that can handle different sheet metal parts, and the standard sets out the provisions that apply to the unit as a product.

It is written for makers of sheet metal and forming machinery, metal fabrication shops that buy or run bending cells, system integrators and test bodies. The standard is voluntary, as the /T in the code shows. It was issued by the Ministry of Industry and Information Technology on 28 April 2026 and is effective from 2 November 2026. The National Technical Committee for Forging and Stamping Machinery Standardization is in charge of it. It is a new standard.
