Double Wheel CNC Spinning Machine D-3500

CNC Metal Spinning Machine – Double Roller AC-D3500 is a double-channel large-diameter horizontal CNC metal spinning machine. The double-side drive is driven by 4 high-power servo motors with a rated thrust of 280KN*2+300KN*2. It can spin metal plates with a diameter of 100-3500mm and process materials such as aluminum, iron, copper, carbon steel, stainless steel, alloys and other special materials. It is a large CNC spinning machine with a total power of up to 200KW.

This CNC spinning machine serves Jiuzhou Head Forging Co., Ltd., specializing in the production of boiler and pressure vessel heads of different specifications, materials and shapes. The machine can be used by large machinery and equipment manufacturers such as construction, hardware, automobiles, fans, military industry, pressure vessels, etc.; AC-D3500 CNC spinning machine is equipped with a heavy-duty spindle reverse thrust mechanism and a double tailstock structure, which plays a key role in spinning large curved workpieces and large spinning molds.

Head Manufacturing: CNC Metal Spinning Vs Deep Drawing

Currently, the main methods for manufacturing large heads are metal CNC spinning, hydraulic spinning and deep drawing, each of which has different advantages.

Advantages of metal spinning heads:

• Low mold investment cost
• Larger diameter heads;
• Relatively low manufacturing cost;
• Suitable for making some thin-walled or large-sized heads;
• The same mold can manufacture heads of different thicknesses and similar sizes;
• The time cycle is relatively short, suitable for some single-piece or small-batch production;
• The molding quality of the head is good and there are no wrinkles;

Advantages of deep-drawn heads:

• High efficiency, suitable for the production of large quantities of small-sized heads

Head installation:

drum press and spinning machine are special machines designed for heads

CNC Spinning Machine For Bottom Head Of Large Rocket Fuel Tank

The overall bottom of a carrier rocket with a diameter of 3.35 meters is manufactured by CNC spinning machine. The bottom of the fuel tank is the most complex in structure, the most difficult to manufacture, and the longest production cycle among the fuel tank components of the carrier rocket.

In the past, the bottom of the rocket fuel tank was welded by multiple melon seed pieces, top cover, and transition ring. Each tank bottom had more than ten main welds. The manufacturing process was very complicated. The weld was the weakest link in the entire tank bottom. The weld destroyed the continuity of the material. It was easy to produce defects such as pores, deformation, and cracks during welding, which affected the reliability of the tank bottom.

The bottom of the tank manufactured by the CNC spinning machine is formed by a CNC program mold. After one clamping, it can be formed as a whole at one time. There are few manufacturing processes and high reliability. The entire tank body has no welds, which reduces the weight by 60 kilograms, reduces the manufacturing cost, and greatly improves the rocket’s payload and safety.
