Aside from the common metal processing methods like stamping, cutting, and casting, metalworking companies are increasingly emphasizing metal spinning. As a chipless process, metal spinning is primarily conducted using manual or CNC spinning machines. Its working principle involves the blank rotating at high speed with the mold while applying substantial external force to the material along a specific path. The roller repeatedly compresses the material, transforming it from point to line, and from line to surface, until the blank undergoes plastic deformation into the desired shape. Since the advent of CNC spinning service, the market has rapidly adopted this method due to its remarkable results. The quality and stability of products produced via CNC spinning are superior, leading to widespread acclaim and adoption by various manufacturers. So, what are the advantages of CNC spinning? Let’s explore.
Advantages of CNC Spinning Components:
1. Excellent Metal Deformation Conditions:
During the spinning process, the contact between the spinning wheel and the metal is almost a point contact. The small contact area results in high unit pressure, reaching up to 2500-3500 MPa. This makes spinning suitable for processing high-strength and hard-to-deform materials, with a significantly lower total deformation force required, thereby greatly reducing power consumption. For components of the same size, the tonnage required for a spinning machine is only about 1/20 of that needed for a press.
2. Wide Range of Products:
The range of products that can be produced via spinning is extensive. Depending on the capabilities of the spinning machine, it can create large-diameter thin-walled tubes, special tubes, variable cross-section tubes, and almost all rotating system parts with stepped and variable wall thicknesses, such as rocket and satellite nose cones and shells. This allows for the production of parts in various special shapes and sizes.
3. High Material Utilization Rate:
Spinning is a non-cutting process, leading to a very high utilization rate of raw materials. Compared to other processing methods, it can save approximately 70% of raw materials. Additionally, the tensile strength and hardness of spun products are significantly improved, with stable and uniform product quality, making it ideal for mass production and reducing production costs.
4. Cost Advantages:
Compared to traditional processing methods, CNC spinning can reduce material waste, lower labor costs, and increase production efficiency. This provides a price advantage in the market, attracting more customers and maximizing profits.
5. High Automation and Intelligence:
With computer control, remote monitoring, fault diagnosis, and production optimization can be easily achieved. This greatly reduces management burdens, allowing companies to focus more on business expansion and customer relationship maintenance.
6. Precision Control:
Although the machining accuracy of CNC metal spinning machines is not extremely high (with a diameter accuracy of 0.1mm for aluminum, about 0.2mm for iron, and about 0.4mm for stainless steel, based on a 100mm diameter), it is sufficient for most applications. If higher assembly precision is required, precision turning can be employed to meet the standards.
7. Broad Applicability:
CNC spinning is suitable for various metal materials, including aluminum, iron, and stainless steel. It can process metal materials with a minimum thickness of 0.5mm, making it highly versatile in many industrial applications.
In summary, the advantages of CNC spinning components are not only in the uniqueness of the processing method but also in its wide application range, high efficiency, and low cost, making it the preferred processing method in many industries.
