Foreword
This standard is a revision of JB/T8085-95 "Accuracy of Combined Punching and Shearing Machines". The technical content of this standard is basically consistent with JB/T8085-95, and has only been re-edited in accordance with relevant regulations. This standard will be implemented from January 1, 2000. This standard replaces JB/T808595 from the date of implementation. This standard is proposed and administered by the National Forging Machinery Standardization Technical Committee. The unit responsible for drafting this standard: Heilongjiang Forging Machine Tool Factory. This standard was first published in October 1984. Scope
Mechanical Industry Standard of the People's Republic of China
Accuracy of Combined Punching and Shearing Machines
This standard specifies the geometric accuracy, working accuracy and inspection methods of combined punching and shearing machines. This standard applies to combined punching and shearing machines (hereinafter referred to as punching and shearing machines). 2 General requirements
2.1 The requirements for accuracy inspection of punching and shearing machines should comply with the relevant regulations on accuracy inspection of forging presses. JB/T6102.1-1999 | | tt | mm is calculated as 0.01mm.
2.3 The accuracy inspection sequence of this standard does not represent the actual inspection sequence. For the convenience of assembly and disassembly of inspection tools and inspection, inspection can be carried out in any order.
