How to save CNC milling costs? Why some custom CNC milling services are expensive? Firstly, we may need to know the cost factors for CNC milling services. 1)Stock Material As with any type of manufacturing, Stock material is the most basic cost. Some materials are more difficult to process than others, and some materials are more expensive as raw materials. The processing speed of some materials is much slower than others, even with the advancement of modern tools and mechanical technology. Some materials can wear out the expensive consumable cutting tools used more quickly, and can vary from one tool that makes hundreds or even thousands of parts to one part consuming multiple tools.Therefore, the material selection of your components can be a huge cost factor. 2)The Specification of CNC Machining Parts The size and overall geometry of the parts are of course important factors in the quotation of machining operations. Obviously, the larger the physical part, th...
