CNC pipe bending machines are widely used in aerospace, automobile manufacturing, shipbuilding, machinery manufacturing, architectural decoration and other fields. In these fields, CNC pipe bending machines can process various complex shapes of pipe parts to meet the needs of different industries.
Recently, ANTISHICNC team received an inquiry. The customer requires automatic and precise bending of stainless steel pipes for the production of Coriolis flow-meters. The pipe bending machine is applied to stainless steel AISI SS316L pipes with a maximum size of 110×8 (DN=110 mm, wall thickness = 8 mm)The accuracy requirements are as follows:
Accuracy of bending: 0.05degree
Accuracy of linear tube shifting: 0.05mm
Accuracy of tube rotation: 0.05degree
