JB/T 13651.2-2019Three-axis machining units for modular machine tools - Part 2: Vertical three-axis machining units - Testing of the accuracy (English PDF)

JB/T 13651.2-2019 is the English-translated version of 组合机床三坐标加工单元 第2部分：立式三坐标加工单元 精度检验.

JB/T 13651.2-2019 covers the vertical machining unit within the Chinese machinery industry standard on accuracy testing of three-axis machining units for modular machine tools.

The part lays down the inspection conditions, the items to be inspected, the inspection methods and the tolerances for the geometric accuracy, the positioning accuracy and the repeat positioning accuracy of the vertical unit.

Its field is the vertical three-axis machining units of flexible modular machine tools and flexible production lines, each with a spindle and three numerically controlled linear axes X, Y and Z whose maximum travel is 1600 mm, while units with a greater travel may take it as a reference.

It quotes GB/T 17421.1-1998 and GB/T 17421.2-2016. Issued on 2 May 2019, it has applied since 1 January 2020.
