Work material thickness的意思|示意

Rollers are mainly the work of the three-driven roller to ensure that any thickness of the material sent to a good rolling function.

三个工作辊均为主驱动辊，保证对任何厚度的材料有良好的送进卷制功能。

However, the deformation is more uniform with regard to billet in contact with the work surface of punch, material thickness decreases less, therefore, the purpose of calibration has been reached.

而与模具工作表面相接触的管坯，其变形则较为均匀，材料壁厚减薄较小，达到扩径整形的目的。
