This standard JB/T 4170—2011 specifies geometric accuracy requirements and inspection methods for sliding jacket feed power units of modular machine tools, applicable to modular machine tools and their automatic lines. It includes 8 geometric accuracy test items (G1 to G8), such as radial runout of spindle centering diameter, parallelism of spindle rotation axis, and axial runout, with tolerances for both normal and precision grades. Inspection methods follow GB/T 17421.1, with specific rules for length conversion. It replaces the 1999 version, with main changes to the responsible committee and terminology.
