CNC machining stands as a subtractive manufacturing technology, systematically eliminating
material from raw stock through computer-generated instructions. Broadly, CNC machines fall
into two categories: those that maintain stationary raw stock while the cutting tool rotates and
those that rotate the raw stock while moving it against a stationary tool.
Variations and combinations of these approaches exist, allowing for the production of parts with
intricate features.
Product Details
The primary materials employed in the CNC machining process are predominantly metals.
These metals encompass alloy steel, carbon steel, cast iron, stainless steel, aluminum, copper,
magnesium, and zinc.
However, CNC machining is not limited to metals alone; it is also capable of machining plastic
parts and working with various materials, including ceramics, composites, thermoplastics, and
thermosets.
Here is a comprehensive overview of the most popular materials

FAQ's
1. CNC Machining Parameters: A Brief Overview
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. Do you provide Quick-Turn CNC Machining services?
Absolutely! We specialize in quick-turn parts with rapid lead times, and many of our parts can be
delivered within 3-4 days. We also offer an expedite option, and our dedicated team collaborates
closely with you to ensure that we meet your most urgent deadlines.
3. What if I am not entirely satisfied with the parts I receive?
We stand behind the quality of our materials and workmanship, as outlined in the terms of the initial
order and the information you provide.
In the event of any disputes stemming from subjective assessments, please bring them to the
attention of our management. They are committed to acting in good faith to ensure your complete
satisfaction. Our ongoing success is built on earning your trust in our capability to meet and surpass
