Applications of CNC Milling
Rapid Tooling
CNC technology can be applied to almost all materials, making it ideal for rapid tooling, such as manufacturing jigs, fixtures, and other tooling components to meet fast-response production needs.
Rapid Prototyping
Wide material selection, low per-unit machining costs, and fast production speeds make CNC machining ideal for prototyping, supporting rapid product validation and iteration.
End-Use Production
High-quality surface finishes, extensive material options, and precise tolerance control make CNC machining the preferred technology for end-use part manufacturing, meeting various industrial application needs.

CNC Milling Tolerances & Standards
| Description | General Tolerance or Standard |
|---|---|
|
Maximum Part Size |
Milled parts up to 80” x 48” x 24” (2,032 x 1,219 x 610 mm). |
|
Distance Dimensions |
For features of size (Length, width, height, diameter) and location (position, concentricity, symmetry): ±.005”. |
|
Orientation and Form Dimensions |
±.005" and angularity of 1/2 degree for parts 0-12". For 24" and beyond, please consult Xometry's Manufacturing Standards. |
|
Standard Tolerances |
Tolerances on metals will be held to ±.005" (±0.127 mm) in accordance with ISO 2768 unless otherwise specified. Plastics and composites are held to ±0.010”. |
|
Precision Tolerances |
Xometry can manufacture and inspect to tight tolerances, including sub ±.001" tolerances, per your drawing specifications and GD&T callouts. |
|
Minimum Feature Size |
0.020” (0.50 mm). This may vary depending on part geometry and chosen material. |
|
Threads and Tapped Holes |
Xometry can accommodate any standard thread size. We can also machine custom threads; these will require a manual quote review. |
|
Surface Finish |
The standard finish is as-machined with a surface roughness of 125 μin Ra or better. Additional finishing options can be specified when getting a quote. |
|
Edge Condition |
Sharp edges will be broken and deburred by default. Critical edges that must be left sharp should be noted and specified on a print. |
Please check out Xometry's Manufacturing Standards for more information on tolerances per process. Unless we have agreed to other tolerances in your Quote, we will work to achieve and hold the tolerances noted.
Overview: What is CNC Milling?
CNC Milling Machine Basics
CNC milling machines are automated cutting devices that remove excess material through a rotating spindle head. Mills come in various sizes and axis configurations, primarily used for machining harder metals, but also compatible with materials ranging from plastics and aluminum to stainless steel and titanium.
How CNC Milling Works
CNC millingBed excels at hardMaterialsPerforms contour machining。Like other CNC machines,Mill byCAMSoftware-generatedGCode-controlled。GCode instructions precisely control tool head position、Spindle Speed、Cutting Depth、Workpiece motion and other speeds、Feed rates and coordination parameters。Code complexity depends on the number of mill axes。
Mills can also be used for softMaterialsContour Cutting,But withCNC EngravingLower cost-effectiveness compared to machines。The main difference between the two is:CNC EngravingWorkpiece stationary during machining,Engraving head rotates around workpiece;WhileCNC millingBed can move both tool head and workpiece。CNC millingBed primarily for industrial manufacturing,CNC EngravingMachines are more commonly used for low-volume manufacturing like woodworking。

Other Advantages of CNC Milling
CNC milling machines are designed for high-precision manufacturing and high repeatability, suitable for rapid prototyping and production needs from low to high volume. Mills can process various materials, from basic aluminum and plastics to high-performance materials like titanium, handling nearly all machining tasks.
