CNC Machining, short for Computer Numerical Control Machining, encompasses various types of
machines that employ computer-controlled tools to subtract material from a workpiece.
This computerized control distinguishes CNC machining as a method that surpasses conventional
machining in terms of speed, precision, and accuracy.
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.
| 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.

FAQ's
1. What are the advantages of CNC machining?
CNC machining offers a spectrum of advantages, prominently featuring rapid prototyping and the
expedited production of full-scale parts. Its hallmark is the ability to achieve exceptional precision
and accuracy in manufacturing, catering to tight tolerances for CNC parts of diverse sizes.
This method stands out for its flexibility, influencing factors such as volume, pricing, lead times,
and the array of materials and finishes available.
2. 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.
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 and capabilities.
Our extensive experience spans decades, during which we have consistently met rigorous regulations
and remained PPAP compliant in industries like automotive, aerospace, and medical devices.
These industries set benchmarks for the quality assurance we uphold across all our manufactured
products.
4. What industries do you typically work in? Who are your typical customers?
It's hard to find an industry we haven't collaborated with! Our clientele represents diverse sectors,
including heavy equipment manufacturing, general commercial enterprises, and businesses in industrial,
transportation, medical, and consumer domains, among others. Our customer base extends across the
United States, Europe, and beyond. What unites them is a shared requirement for precision-machined
parts delivered on time and within budget constraints.
