In the field of metal pipe laser cutting motion control, machining accuracy is one of the most important consideration factors, however, when a double-chuck is used for cutting a long part, like a double-chuck cutting device adopted in the laser cutting machine pipe rotation automatic feeding device, the actual cutting effect (see attached figure 2) can be greatly reduced due to pipe deformation caused by gravity, in addition, after the chuck moves to a forward stroke, a section of metal pipe between the chuck and the cutting head cannot be continuously processed, the section of metal pipe is often called as 'tail material', and when the double-chuck is used for cutting, the 'tail material' which cannot be avoided can cause material waste and reduce the income of customers.
The cutting method of the three-chuck machine used in the market at present adopts a solid chuck, cannot feed and pull materials in a reciprocating manner, has requirements on the length of a pipe, cannot meet the requirements once a long pipe needs to be processed, and adopts a two-chuck structure as a hollow chuck.
