Processing of typical parts on CNC lathe（2）

2 Processing of parts

After several trial processing, it was found that if one molding and rolling process is used, because the product is deformed too much at the time of extrusion, the heat generated is too large, so the product will be pulled around the corner and the product will be scrapped. The author uses three form roll Press the processing map y, and get good results. The processing steps are:

The first knife rolls the aluminum alloy with the front end surface, and the other parts are rolled into a trumpet shape. The second knife approaches the front end surface, rolls the aluminum alloy close to the mold core, and makes it close to the mold core. The knife starts to move backward from the front end surface, and it is rolled by imitation. The aluminum alloy is uniformly rolled and formed into three steps to reduce its deformation, thereby reducing the rolling force and the generated The temperature, well and heat can be well dissipated from it. When rolling, the thickness of the first two knife aluminum alloy is a6m and the third knife squeezes it to the thickness of a4m. In each knife, the speed The s and feed rate r points are relatively large, respectively, 1200m and 250mmmn, so that it will not cause the aluminum alloy and the tool to be continuously rubbed in one place and generate a large amount of heat. 3 Conclusion The use of CNC lathes for mold rolling processing, not only Increased material utilization also reduces costs and has greater flexibility. Short production cycles can solve traditional manual floor-to-floor processing and unnecessary mold processing.
