CNC bending has different hardness, which is very different from fracture. It is suggested that the selection of raw materials should be carried out, and the aluminum plate with low hardness should be selected as far as possible. The practice also proves that the aluminum plate of equivalent material is bent, and the possibility of damage is greatly reduced by thin aluminum plate。

?In the process of NC bending, one of the most important purposes of the bending machine die is to produce uniform machining allowance for each bending. That is to say, bending dies with different angles must be used and the main bending machine dies should be as close to the final shape of the dies in each process as possible。CNC bending processing factory will be evenly distributed machining allowance to ensure constant high productivity and safe bending process. When the angle is constant, the NC bending speed and feed rate can also be kept at a high level. In this way, the die action and workload on the bending machine change very little, resulting in less heat and fatigue, thus increasing the life of the bending machine die。

??CNC punch processing factory gantry milling machine has the characteristics of sufficient stiffness, high efficiency, convenient operation, simple structure and good comprehensive performance. Gantry milling machine is suitable for milling horizontal plane, vertical plane or chute of large and medium-sized black or non-ferrous metal parts on various machines. The boring head can also be used for drilling, drilling and various improvements according to the needs of users. At the same time, it can undertake various additives。
??Definition of CNC milling machine
??Portal frame milling machine and horizontal long machine. The milling machine has high machining accuracy and productivity, and is suitable for large-scale machining of large workpiece plane and inclined plane. CNC milling machine can also process space curved surface and some special parts. The milling machine consists of a column and a top beam to form a portal frame. The beam can move along two rows of guide rails (see Machine Guide). Move. The crossbeam has 1-2 milling heads with vertical spindle, which can move laterally along the beam guide rail. A milling head with horizontal spindle can also be installed on the two columns, and the milling head can be lifted and lowered along the guide rail of the column. These milling heads can process multiple surfaces at the same time. Each milling head has a separate motor (Zui up to 150 kW), a speed change mechanism, a control mechanism and a spindle。
??CNC punch processing factory parts (see machine tool spindle), etc. During machining, the workpiece is mounted on the worktable and fed longitudinally (see machine tool). The total weight of gantry large milling machine (Table 6 × 22 m) is 850 tons. There are also some varieties of gantry milling machine to adapt to different processing objects. (1) Gantry milling and boring machine: the beam is equipped with milling and boring head, and its main shaft (sleeve or RAM) can be used as boring machine. Axial motion feed and motion fine adjustment device, fine adjustment speed can be as low as 5 mm / min. 2。 Bridge type gantry milling machine: when working, the worktable and workpiece will not move, but the gantry frame will move. It is characterized by small area, large bearing capacity, gantry travel up to 20 meters, easy to process super long or overweight workpiece。
