The term CNC, short for computer numerical control, characterizes the technology at the core of
CNC machining, a process where machining operations are guided and managed by a computer.
This computerized approach enables the efficient production of parts with heightened speed,
accuracy, precision, and the capability to achieve intricate geometries beyond the reach of manual
machining.
Moreover, CNC machining diminishes the reliance on manual labor for machining tasks that would
traditionally be performed by humans. While individuals are not directly involved in the physical
machining of each part, their involvement is pivotal in programming and operating CNC machines
to ensure the smooth execution of every operation.

Post-processing and surface finishes for CNC machining
CNC-machined parts as they emerge from the machine often exhibit visible tool marks, a feature
that may not align with your specific part requirements.
Fortunately, there exists a multitude of post-processing techniques aimed at enhancing the surface
appearance and elevating attributes such as wear resistance, corrosion resistance, and chemical
resistance.
Methods like anodizing, bead blasting, and powder coating present viable options for refining the
final presentation of your custom parts, allowing you to achieve the desired surface quality and
performance characteristics.

FAQ's
1. What are standard machining tolerances?
Standard machining tolerances are set at ± 0.005" or 0.13mm, delineating the acceptable range
for dimensions. For example, if a CNC machining tool carries a tolerance of ± 0.01 mm, it signifies
a permissible deviation of 0.01 mm in each cutting operation.
Leveraging a provided drawing, our CNC machining service can attain part tolerances as precise as
± 0.0002 in. In cases where no drawing is available, all CNC parts adhere to our ISO 2768 medium
standard. Projects requiring even tighter tolerances, such as ±0.025mm or ±0.001", can be
accommodated with an engineering drawing specifying critical features.
2. What size of fillets are added when no specific fillet is specified by the 3D model
or drawing?
When no specific fillet radius is outlined in the 3D model or drawing, the machinist will incorporate
fillet radii at their discretion to optimize for easy machining.
In instances where a particular fillet radius is needed, explicit specification is encouraged.
As a rule of thumb, consider internal vertical edge radii exceeding 1/3 of the depth, while internal
horizontal edges may either remain sharp or be introduced with a radius ranging from 0.5mm to 1mm.
3. Quality Assurance
The trust our customers place in us is paramount. We adhere to proven quality management
principles to not only meet customer satisfaction but also to continually elevate our performance
