Why Is Cnc Parts Machining So Expensive?
Table of Contents
Why CNC machined parts are so expensive is related to machining quantity, machining time, material cost, setup time, and other design factors.
1.Machining Quantity
The price of bulk parts and bulk quantity is definitely different.
2.Machining time
The longer it takes to machine an aluminum part, the higher the CNC cost. Machining time is the main driver of CNC cost.
3.Material Cost
Blank material cost is a significant part of CNC machining cost. Material costs can be reduced by optimizing the design to use standardized blanks as much as possible and reducing scrap. Aluminum alloys are currently one of the more affordable and well-machined raw materials.
4. Setup time
When CNC parts processing is small, the preparation of the geometric model and the planning of the machining process seriously affects the CNC cost of machining aluminum alloy parts. This part of the cost is a fixed cost, can be shared through mass production.
5. Other design factors
When the CNC part machining design has special requirements (e.g., precision tolerance requirements and thin-wall designs), special tools, more precise quality control, lower machining speeds, and more complex machining steps are required, all of which can seriously affect CNC costs.
