For instance, aluminum is lightweight and resistant to corrosion, making it suitable for aerospace applications, while stainless steel offers superior strength and durability for heavy-duty applications. Additionally, understanding the machining characteristics of each material can help you anticipate potential challenges during the milling process, such as tool wear or machining speed.
Tolerances refer to the allowable variations in dimensions and are crucial for ensuring that parts fit together correctly. When ordering CNC milled parts, it is important to specify the required tolerances for each dimension. Tight tolerances may require more advanced machining techniques and can increase production costs, so it is essential to balance precision with budget considerations. It is also beneficial to communicate the functional implications of tolerances to the manufacturer. For example, if a part is intended to fit with other components, understanding how tolerances affect assembly can help ensure a successful fit and function.
Finding the right supplier is a vital step in the ordering process. Look for manufacturers with a proven track record in CNC milling and positive customer reviews. Consider their capabilities, such as the types of materials they work with and the range of CNC machines they have available.
