CNC machining finds its best application in one-off manufacturing projects and in the
low-to-medium volume production range, spanning from several hundred to 1000 parts.
It stands out as the most economically viable option for the production of metal prototypes,
making it a preferable choice. Furthermore, CNC machining is the ideal selection when the
parts in question require exceptionally tight tolerances.

FAQ's
1. How much do CNC machining materials cost?
The multitude of materials available for CNC machining introduces a range of costs,
influenced by the unique properties and characteristics of each material.
In the realm of metal parts, Aluminum 6061 is a standout for its economical pricing.
If cost efficiency is a priority, ABS takes the lead as the most budget-friendly option.
Importantly, the ease of machining is a key factor impacting costs.
Stainless steel, known for its hardness in comparison to aluminum, presents higher
machining complexities, contributing to an overall increase in costs.
2. What's the general surface texture of CNC milled and turned parts?
The surface texture of machined milled parts is commonly around 3.2μm (or 1.6μm for more
recent machines). In the case of turned parts, a finer surface finish is achieved, reaching a
roughness of 0.8μm. Notably, this enhanced surface texture in turning is accomplished without
the necessity of adjusting machining speeds.
3. The cost of CNC machining a part is shaped by a variety of factors, including:
1. Material: Material selection introduces cost variations, with materials like aluminum being
more economical to machine compared to others like Inconel, attributed to factors such as tool
wear and cutting speeds.
2. Complexity: Parts featuring intricate designs incur higher machining costs. The complexity
of surface shapes, for instance, significantly influences overall machining expenses.
3. Tolerances: The precision demanded by dimensional tolerances impacts CNC machining costs.
Imposing overly tight tolerances on non-critical features can lead to unnecessary cost escalation.
4. Surface Finish: Achieving mirror finishes demands specialized tools and machining strategies,
extending machining time and, consequently, increasing costs.
5. Quantity: Production volume is a key determinant of costs. Low-volume production tends to
be costlier per part, as initial setup and programming costs are distributed over a smaller
production run.
