Mastering Metal: Exploring ALTRON CNC Metal Spinning and Expanding Process
The spinning metal process about inner spinning machine
Based on the metal spinning process, this technology utilizes an innovative “fixed-point material, mobile spinning” operating model, integrated with CNC intelligent control. This technology leverages the metal spinning process’s advantages of high consistency and precision in forming metals, achieving efficient, accurate, and economical sheet metal forming. Our machines offer strong support for companies shortening R&D cycles and enhancing product competitiveness, making them an excellent choice.
What is an inner spinning machine？
Inner spinning machines form sheet metal by clamping the material while a rotating wheel moves. Unlike traditional machines, this device uses a specialized fixture to hold the sheet metal while a computer-controlled rotating wheel moves along a preset path, gradually applying force from the inside of the sheet toward the outer edge, achieving precise forming.
Why choose an inner spinning machine？
1. Efficiency：Fast production speed, saving time and costs.
2.Stable quality: The CNC system produces according to the provided program, ensuring product stability.High precision allows for the creation of solid molds based on key dimensions.
3. Guaranteed thinning rate:The material will become thinner during the forming process. Guaranteed thinning rate ensures lightweight design while maintaining sheet strength.
4. Cost savings ：Low initial investment.The inner spinning machine is suitable for early product development and reduces trial and error costs.
5. Customizable :Machines of different sizes can be customized according to customer requirements.
6. Small batch friendly: Ideal for small batch production or early product development.
The difference between internal rotation machine and deep drawing
Deep drawing is a traditional metal forming process suitable for mass production. Although both methods can achieve forming, their core principles, performance and application scenarios are completely different, especially in rectangular products such as air conditioner panels:
|
Comparison Dimension |
Internal Rotation Machine |
Deep Drawing |
|
Core Principle |
The raw material does not move, the spinning wheel moves |
Uses a rigid punch to push metal sheets into a matching die, relying on mold constraints. |
|
Time period |
The development cycle is short, suitable for early development of test products |
The development cycle is long, suitable for later development |
|
Applicable Batch Size |
Support small batch production of 50-1000 pieces |
Economical only for large batches ; small batches are cost-prohibitive. |
|
Material Adaptability |
Compatible with thin (0.3mm) to thick (5mm for carbon steel) sheets; works with aluminum, galvanized steel, and stainless steel. |
Struggles with ultra-thin sheets (prone to tearing) and thick sheets (high die wear); limited material flexibility. |
