Centerless machine tools in the tube industry
Nowadays, all kinds of machinery are getting more and more precise, and the requirements for components are getting higher and higher. Today, we will talk about the application and advantages of centerless machine tools in the steel pipe industry.
First, the centerless lathe processing mandrel than the conventional process is several times more efficient, can significantly reduce processing costs. Steel pipe mandrel is the more important work mold in the limited movement mandrel continuous tube rolling unit. Through the joint action of mandrel and roll, the tube can be formed according to the requirements of the finished product with the specified size of bore and outside diameter. Therefore, the quality of the mandrel determines the geometric accuracy and apparent quality of the steel pipe lining.
Second, the centerless lathe plus planetary sand mill by rough turning, finishing and polishing process can be completed in just a few minutes. At the same time can ensure both the dimensional accuracy of the mandrel and the surface quality of the mandrel. Moreover, the centerless lathe adopts multi-cutter cutting process at the same time, and the trimming part of its tool reaches 15-25mm in length, so it can realize the larger walking speed of the centerless lathe.
Third, at the same time, centerless lathe tool working part of the contact area is also several times larger than the conventional lathe, and the tool is in the fully cooled conditions, so as to ensure a large feed rate, but also to ensure the durability of the tool.
Fourth, centerless lathe can also be high-grade alloys, stainless steel, titanium alloys and other materials such as billet skinning. After skinning can remove the decarburization layer, cracks and surface defects, and thus improve the quality of the pipe.
