The sectional auger flight making machine is used for processing sectional augers. This line includes hydraulic system、mechanical system and electric control system. The hydraulic system drives moulds on the foundation to reciprocating move, and this makes two moulds interactional to change steel plate shape to be augers. This machine just needs one set mould to achieve multitudinous standard augers process. It is easy to operate, has high production efficiency and great working accuracy, and ect.
