But because of their poor rigidity, it is easy to bring machining deformation caused by the existence of the residual stress and the fixing stress.

Variation simulation analysis has been used in the design stage to predict such uncertainties, but variation analysis based on rigid body assumptions usually overestimates the assembly variations.

This machine adopts large roller conveying chain as the driving part, which is driven by chain wheel and loaded by the rigid plate for the constant conveying.
