Formula calculation method for cylindrical spiral expansion size
Cylindrical spirals are a common form of construction for many parts on machinery, especially in agricultural machinery and food machinery. Therefore, the manufacturing of spirals is a problem often encountered in production. The key to spiral processing and manufacturing is to stake out the material and correctly stake out the material, which is an important prerequisite for ensuring that the spiral forging shape meets the design requirements.
