Radial Forging Machine
This standard specifies the geometric accuracy, working accuracy and inspection method of radial forging machines. This standard is applicable to radial forging machines for forging sections and shear surfaces of ferrous or non-ferrous metal materials. 2 General requirements
2.1 The requirements for radial forging machine accuracy inspection shall comply with the relevant provisions for forging machine accuracy inspection. 2.2 The installation level of radial forging machine in longitudinal and general directions shall not be greater than 0.10-1000JB/T9955,2-1999
Replace 28362004-87
2.3 The tolerance value of the test item shall be calculated according to the actual test length. When the calculated result is less than 0.005m or equal to 0.005mm, it shall be ignored. When it is greater than 0.005mm, it shall be calculated as 0.01mm.
2.4 The inspection sequence of this standard does not represent the actual inspection sequence. For the convenience of inspection and testing, the inspection can be carried out in any order.
