The stainless steel spinning technology is a dual-purpose boring and spinning machine tool modified by a lathe. First, the inner diameter of the cylinder to be repaired is bored to remove the damaged layer (the process of boring the damaged layer has the function of straightening the cylinder and removing the expansion of the inner diameter), and then press After inserting the special stainless steel welded pipe, the welded pipe and the inner wall of the cylinder are mechanically extruded with an internal spinning tool, and then the two ends of the steel cylinder are welded together with the cylinder block by welding to complete the remanufacturing and repair of the inner surface of the cylinder process. The following stainless steel processing manufacturers-tell you about several major issues that need to be paid attention to in stainless steel spinning processing.
1. The surface of the blank needs to be brushed with stretching oil
During the process of stainless steel spinning, the temperature of the material, mold, and cutter wheel is very high, so it is necessary to continuously coat the surface of the material and the mold with drawing oil. The drawing oil has a lubricating effect and is attached to the surface of the material. Oil also has a cooling effect.

2. The cutter wheel needs hard materials
The general spinning cutter wheel is made of CR12 steel, but spinning stainless steel, CR12 steel is not hard enough, the cutter wheel is easily scratched by the stainless steel material, and there will be many scratches on the surface of the formed product.
3. Cutting tool wear
After the stainless steel spinning is completed, it is often necessary to trim the edge. The trimming is turned with a turning knife blade. Due to the high hardness of the stainless steel material, the blade is easy to wear. After the blade is worn, the stainless steel cutting edge will have many burrs, so you need to pay attention to it during production. Whether the stainless steel blades are worn or chipped, the blades need to be replaced in time.
Fourth, the gap between the spinning cutter wheel and the mold
The temperature rise of the spinning process for a long time causes the gap between the cutter wheel and the mold to become smaller, and the gap between the cutter wheel and the mold needs to be adjusted in time. The thicker stainless steel material will increase the temperature during the processing process.
