CNC machining, standing for Computer Numerical Control machining, is a subtractive
manufacturing technology where material is automatically removed from raw stock according
to computer-generated instructions. In broad terms, CNC machines are categorized into two types:
those that keep the raw stock stationary while rotating the cutting tool, and those that rotate the raw
stock while moving it against a stationary tool. Various deviations and combinations of these basic
approaches exist, allowing some machines to employ both techniques simultaneously to produce
parts with intricate features.
Product Details
The CNC machining process predominantly employs metals as its primary materials.
These metals encompass alloy steel, carbon steel, cast iron, stainless steel, aluminum, copper,
magnesium, and zinc.
Nonetheless, this versatile process can also be applied to machine plastic components and work
with an array of other materials, including ceramics, composites, thermoplastics, and thermosets.
| Common Materials | |
| Name | Description |
| Aluminum | High machinability and ductility, good strength-to-weight ratio. |
| Stainless steel | High tensile strength, corrosion and temperature resistant. |
| Mild steel | High machinability and weldability, high stiffness. |
| Brass | Low friction, excellent electrical conductivity, golden appearance. |
| Copper | Excellent thermal and electrical conductivity. |
| Titanium | Excellent strength to weight ratio, used in aerospace, automotive and medical industries. |
| ABS | Common thermoplastic, impact resistant, easy to machine. |
| Nylon | Excellent mechanical properties, thermal, chemical and abrasion resistant. |
| POM | High stiffness, high accuracy, low friction, easy to machine. |
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.
