Classification of CNC turret punching machine

According to the structure, it can be divided into two categories:
 
1. Open CNC punching machine: The structure is C-shaped, and one side is open. Advantages: Low cost, convenient for loading and unloading workpieces, and convenient for large-scale sheet metal processing. Defects: The low tonnage can only reach 35 tons, and the accuracy is reduced when the tonnage exceeds 35 tonnage.
 
2. Closed CNC punch: O-shaped mechanism, no open surface. Advantages: high tonnage of 35 tons and above can be manufactured, with good stability. Suitable for high-precision sheet metal processing. Defects: The cost is higher than that of an open CNC punch, and the loading and unloading must be from the left and right sides.
 
According to the working stamping method:
 
1. Mechanical transmission: use the flywheel rotational inertia to drive the striking head for punching. Advantages: low cost and easy maintenance; Defects: high noise and limited tonnage.
 
2. Hydraulic transmission: use hydraulic cylinder motor to drive the striking head for stamping. Advantages: low noise, high tonnage; Defects: high cost, requiring maintenance by personnel.
