1. Single punching: punching is completed in a single time, including straight-line diffusion, arc diffusion, circumferential diffusion, and punching of grid holes.
2. Continuous blanking for the same purpose: the rectangular production model is used for partial overlapping processing, which can be used for processing long holes, trimming, etc.
3. Continuous blanking for the purpose of multi-target: the processing method of processing large holes with small production models.
4. Nibbling: using a small round die to continuously punch an arc with a small step distance.
5. Single forming: the processing method of one-time shallow deep drawing forming according to the shape of the production model.
6. Continuous forming: forming processing methods that are larger than the size of the production model, such as large-size louvers, rolling ribs, rolling steps and other processing methods.
7. Array forming: processing multiple identical or different workpieces on a large plate.
