Machining brass involves cutting and shaping the metal using CNC milling and turning equipment. This method is highly precise and allows for the creation of custom-designed fasteners with uniform quality and minimal dimensional deviations. Brass’s excellent machinability makes it particularly advantageous for producing detailed and intricate parts.
Different methods are used to produce brass fasteners, each suited to specific needs:
Cold forging is a common method for manufacturing standard fasteners. It involves using coiled wire or bar stock at room temperature, which is then sheared, punched, and formed through multiple workstations to achieve the final shape. This process is efficient and produces high-strength fasteners.
Hot forging is used for larger diameter fasteners and involves heating the brass to high temperatures to make it more malleable before forming it in a forging press. This method allows for the creation of complex shapes and is often used for heavy-duty fasteners.
Machining remains a critical method for producing brass fasteners, especially when precision is paramount. CNC milling and turning machines are used to cut and shape brass bar stock into fasteners with exact specifications. This method ensures high precision and consistency across batches.
After shaping, the next step is thread formation. Thread rolling machines are typically used for this purpose, where the brass is placed between dies that form the thread. This cold forming technique results in smooth, precise, and uniform threads without altering the material’s microstructure.
