When purchasing a gantry punch, you need to grasp the following points:

1、 Tonnage: gantry punch has different tonnage, so it is important to choose the appropriate tonnage for reducing the cost of machine deployment and production process. The so-called punch tonnage refers to the instant impact force released by the punch in the process of operation. Relatively speaking, there are three common tonnage of gantry punch: 160, 190 and 400. The higher the tonnage is, the higher the machining accuracy will be. Of course, the cost will also be increased.

2、 Accuracy: the accuracy of gantry punch mainly depends on parallelism, perpendicularity and total clearance. Of course, the accuracy of the gantry punch is also related to the tonnage mentioned above and the machining accuracy of the punch itself. The speed control of the gantry punch also affects the accuracy of the gantry punch.

3、 Energy consumption: when purchasing punch, the energy consumption of punch is also an important item. Reducing energy consumption can reduce the product cost.

4、 Stability: a qualified punch machine shall have qualified stability device to ensure the safety of employees and products.

A non plate part or device for removing work (sequence) parts from the external surface of the punch by gantry punch. The unloading plate is a fixed or movable plate part that unloads the material or work (sequence) parts from the punch. Discharge plate is sometimes made with the guide plate, and also plays a guiding role, still known as the discharge plate. The unloading screw is a screw fixed on the spring unloading plate, which is used to limit the static position of the spring unloading plate. In order to improve the service life of gantry punch, it is required to avoid direct sunlight and other heat radiation, and also avoid places where too wet, too much dust or corrosive gas are avoided. The corrosion gas is easy to deteriorate the electronic components after corrosion, which causes poor contact or short circuit between components, which affects the normal operation of CNC punch.
