　　2、 Material cutting

　　Purpose: According to the requirements of the engineering data MI, cut into small production pieces on large sheets that meet the requirements, and produce small pieces that meet the customer's requirements.

　　Process: Large plate material → Cutting according to MI requirements → Curing plate → Fillet angle/edge grinding → Plate discharge

　　3、 Drilling

　　Purpose: Based on engineering data, drill the required hole diameter at the corresponding position on the sheet material that meets the required size.

　　Process: Stacking pin → Upper plate → Drilling → Lower plate → Inspection/repair
