Henan Chalco 7075 aluminium seamless bus tube machine tool shaft has not been able to make a breakthrough, such as machine tool manufacturing and numerical control system is also such, a lot of breakthrough products, are not completely domestic, and is more symbolic than practical significance.
This situation is expected to be changed in the next few years.Second, the machine tool industry has been clearly included in the 12th five-year high-end manufacturing plan, which will promote the machine tool industry to make great progress.
After bearing damage, the normal position of the extrusion roller will be destroyed.Take the two-roller extrusion roller device as an example. Generally, there are two sets of bearings in the extrusion roller. When one of them is damaged, the extrusion roller loses control, and 7075 aluminium seamless bus tube will be higher and lead to lap welding.During the production run, we can observe the swing of the extrusion roll.When the upper bearing is damaged, the swing range of the roller is larger, while when the lower bearing is damaged, the swing range of the roller is smaller, which is also related to the degree of bearing damage.
The main products of Henan Chalco are: high strength aluminum alloy 7075 aluminium seamless bus tube, precision aluminum tube, large diameter seamless aluminum tube, spinning tube, forging tube.Product features are: high technical content, batch specifications flexible, high added value.
