JB/T 11998.1-2014 (English Version) PDF

Scope: This part of JB/T 11998 refers to GB/T 17421.1-1998 and GB/T 17421.2-2000, and stipulates the geometric accuracy inspection, CNC axis positioning accuracy and repetitive positioning accuracy inspection and processing inspection of CNC EDM micro-hole processing machine tools, and also The tolerance values corresponding to the above inspections are specified. This section defines the terms used for the main components of machine tools, and names the coordinate axes with reference to the provisions of GB/T 19660-2005. This section applies to CNC EDM micro-hole processing machine tools (hereinafter referred to as machine tools) that can process hole diameters of 0.2 mm and below. This section only involves the inspection of machine tool accuracy, and is not applicable to the inspection of machine tool operation tests (such as vibration, abnormal noise, crawling of parts, etc.) or its parameters (such as speed, feed, etc.). These inspections are usually performed during accuracy inspection. proceed before.
