CNC, an abbreviation for computer numerical control, defines the underlying technology in CNC
machining, a process where machining operations are controlled and directed by a computer.
Through computerized automation, CNC machining enables the swift production of parts with
enhanced speed, accuracy, precision, and the ability to accommodate intricate geometries that
surpass the capabilities of manual machining.
Additionally, CNC machining alleviates the manual labor involved in machining tasks, which would
otherwise be performed by humans. Even though individuals are not directly engaged in physically
machining each part, their involvement is indispensable in the programming and operation of CNC
machines, guaranteeing the successful execution of every operation.
Product Details
The primary focus of the CNC machining process revolves around metals, incorporating alloy steel,
carbon steel, cast iron, stainless steel, aluminum, copper, magnesium, and zinc.
Nevertheless, CNC machining extends its capabilities beyond metals to encompass plastic parts
and other materials, including ceramics, composites, thermoplastics, and thermosets.
Common Materials | |

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. |
POM | High stiffness, high accuracy, low friction, easy to machine. |
ABS | Common thermoplastic, impact resistant, easy to machine. |
Nylon | Excellent mechanical properties, thermal, chemical and abrasion resistant. |
CNC Machining Tolerances
Typical machining tolerances fall within the range of ± 0.005 inches or 0.13 millimeters.
Tolerances represent the allowable variation for a specific dimension.
For instance, if a CNC machining tool has a tolerance of ± 0.01 millimeters, it means that the tool
can deviate by 0.01 millimeters in each cut.
When provided with a drawing, Our CNC machining service can achieve CNC parts with tolerances
as tight as ± 0.0002 inches.
In the absence of a drawing, all CNC parts are manufactured according to our ISO 2768 medium
standard. We can also work to even tighter tolerances, such as ± 0.025 millimeters or ± 0.001
inches, when an engineering drawing specifies critical features.
CNC Turning Tolerances | ||
Limits for nominal size | Plastics | Metals |
0.5mm* to 3mm | ±0.1mm | ±0.05mm |
Over 3mm to 6mm | ±0.1mm | ±0.05mm |
Over 6mm to 30mm | ±0.2mm | ±0.10mm |
Over 30mm to 120mm | ±0.3mm | ±0.15mm |
Over 120mm to 400mm | ±0.5mm | ±0.20mm |
Over 400mm to 1000mm | ±0.8mm | ±0.30mm |
Over 1000mm to 2000mm | ±1.2mm | ±0.50mm |
Over 2000mm to 4000mm | ±2.0mm | |
*Please clearly indicate tolerances for nominal sizes below 0.5mm on your technical drawing. |
Applications of CNC Turning
CNC machining stands as a revolutionary force across various industries, offering unparalleled
versatility. In woodworking, CNC machines transform the production of wooden furniture, providing
a time-efficient and cost-effective alternative to manual craftsmanship.
The technology's precision is harnessed in lettering and engraving systems, where it serves to
mark patterns or text onto surfaces, meeting artistic and serialized requirements.
Within the electrical industry, CNC machining plays a pivotal role in tasks such as crafting
component mounting holes in printed circuit boards and producing heat sinks for electronics.
The pharmaceutical sector benefits from CNC machines in manufacturing precise equipment,
including metering pumps, ingredient-dispensing nozzles, and packaging components.
Even in the dynamic consumer goods industry, CNC machining contributes significantly to the
creation of custom material-handling machinery for the food and beverage sector, along with the
production of injection-molded plastic molds essential for food packaging.
