φ2×copper material = difficult to process. What is the reason that the material properties raise the hurdle?
High precision, fine, copper material. The moment they are assembled, the difficulty of processing skyrockets.
The request from the customer was for high-precision machining of copper pins, reducing from φ6 to φ2, with M4 tapping included. At first glance, copper may seem like an "easy-to-machine material," but due to its softness and tendency to deform, along with strict tolerances, general lathes cannot handle it, making precision machining with NC lathes essential. However, for extremely small diameters like this, chucking on an NC lathe itself is difficult. A partner who previously processed φ4 SUS material also responded that they could not accommodate this condition. Nevertheless, we did not give up and found a machining company within the "Hometown Processing Network" that has specialized technology for small diameters, successfully leading to an order. Copper material × high precision × extremely small diameter—this project made me realize that a comprehensive knowledge of materials and a strong machining network are necessary to address all these factors. *This kind of response is just a small part of what Bandai does every day.
