Description

However, when the laser cutting is applied to the motor stator and rotor sheet product processing with very thin silicon steel sheet thickness (generally below 0.5 mm), the problem of poor rigidity and easy deformation caused by the very thin silicon steel sheet thickness will be encountered, which makes it impossible to achieve high precision of laser cutting. The fixture structure used by the existing laser cutting machine cannot completely solve the problems of poor rigidity and easy deformation of the silicon steel sheet, which makes it difficult for the laser cutting to meet the high requirements of the size and position of the stator and rotor sheet product and the consistency of the tolerance, which greatly limits the advantages of the laser cutting and the application of the laser cutting to the stator and rotor sheet product in the motor industry.
