CNC Milling FAQs

CNC machining is a broader term that encompasses various subtractive manufacturing processes, including CNC milling. CNC milling specifically refers to the process of removing material from a workpiece using rotary cutters. Other CNC machining processes include turning, drilling, and electrical discharge machining (EDM).

The duration of a CNC milling project depends on several factors, including the complexity of the part, the material used, the tolerances required, and the machine's capabilities. Simple parts may be completed in hours, while complex components can take several days.

Tolerances in CNC milling can vary depending on factors like the machine's precision, the material being used, and the complexity of the part. In general, CNC milling can achieve tolerances in the range of a few thousandths of an inch (0.001 inches or 0.0254 millimeters) or even tighter for high-precision applications.

Selecting the right CNC milling service provider involves evaluating their capabilities, experience, quality assurance processes, equipment, and pricing.

Yes, CNC milling is commonly used for prototyping. It allows for the rapid and precise production of prototype parts, enabling design validation and testing before full-scale production.

The cost of CNC milling projects depends on factors like material cost, machine setup time, labor, tooling, complexity of the part, and desired tolerances. To manage costs effectively, consider material selection, batch size optimization, and efficient programming of toolpaths. Obtaining quotes from multiple service providers can also help in cost comparison.
