Turning Machine Parts
CNC machining, short for computer numerical control machining, is a subtractive manufacturing
process that utilizes a fusion of computerized controls and machine tools to systematically
remove layers from a solid material block.
The programmed instructions for desired metal cuts are aligned with specific tools and
machinery, orchestrating the machining process in an automated manner.

CNC Machining Applications
CNC machining is a go-to manufacturing process to get precision parts, whether for prototyping
or end-use production.
It is widely used throughout the aerospace, medical, automotive industries for its ability to rapidly
manufacture precise parts in production-grade materials, such as:
1. housings and enclosures
2. brackets
3. fixtures for manufacturing
4. gears and bearings
5. internal mechanical components
6. medical instrumentation

FAQ's
1. A quick guide to CNC machining parameters
Machining parameters in CNC are primarily established by the machine operator during the
generation of G-code. Key parameters include the build size and accuracy of CNC machines,
distinguishing them notably from 3D printers.
CNC milling systems boast a substantial build area, with the capability to machine parts up
to 2,000 x 800 x 100 mm (78” x 32” x 40”). Meanwhile, CNC turning systems specialize in
machining parts with a diameter of up to Ø 500 mm (Ø 20’’).
Precision and tight tolerances are hallmarks of CNC machining. Achieving accuracy levels
surpassing half the diameter of an average human hair (± 0.025 mm or .001’’) is well within
the capabilities of CNC machines. In the absence of specified tolerances in the
technical drawing, operators typically machine parts with an accuracy of 0.125 mm (.005’’).
2. How much do CNC machining materials cost?
The cost of CNC machining materials is diverse and depends on the chosen material,
with variations in prices based on their physical properties. A wide range of materials is
available for CNC machining, each carrying a distinct price tag.
Aluminum 6061 stands out as the most economical choice for producing metal parts.
If affordability is a priority, ABS is the most budget-friendly option. The ease of machining
also influences costs, as seen with stainless steel. Due to its hardness compared to aluminum,
machining stainless steel is more challenging, contributing to an elevated total cost.
3. How long does delivery time and quotation take?
The delivery time for parts is categorized based on complexity:
Low-complexity parts: 2-3 days
Moderate-complexity parts: 2-5 days
High-complexity parts: 5-15 days
Quoting time is dependent on the design complexity:
Simple designs: 1 business day or faster
Moderate to complex designs: 3+ business days
