1. Introduction: The demand for CNC machining in the era of Industry 4.0
As production speed and efficiency become increasingly demanding, manufacturing businesses must adopt advanced technologies to ensure product quality and optimize production costs. One of the most widely applied technologies today is CNC Milling.
In Vietnam, Viet Son Mechanical is a pioneer in the field of precision mechanical processing, especially CNC Milling, with a team of experienced technicians and a modern machinery system. With the motto “Precision – Sustainability – Dedication”, Viet Son Mechanical is always the top choice for both domestic and international enterprises when it comes to machining highly technical components.
2. What is CNC Milling?
CNC Milling (Computer Numerical Control Milling) is a precision machining method where material is cut and shaped using a milling machine controlled automatically through computer programming.
Unlike traditional milling methods, CNC Milling uses encoded programs (G-code) to control tool movements, spindle rotation, speed, cutting depth, and milling paths. This ensures absolute precision and high repeatability for both mass and single-piece production.
Advantages of CNC Milling over conventional milling:
- Precisely controls each detail with extremely low tolerance (under 0.01mm).
- High processing speed, reducing production time.
- Capable of machining complex 3D profiles or tight-tolerance components.
- Flexible in design changes.
- Minimizes human error and reduces waste.
3. Applications of CNC Milling in industrial production
Thanks to its high precision and ability to process a wide range of materials, CNC Milling is widely used in many industries:
a. Machinery manufacturing
CNC Milling is indispensable in producing machine parts, mechanical assemblies, and industrial machinery like packaging machines, presses, CNC machines, and more.
b. Mold making industry
In mold making (plastic molds, metal casting molds, rubber molds…), CNC Milling helps create complex contours with high accuracy and smooth surfaces, minimizing the need for polishing.
c. Automotive – motorcycle – aerospace
Components like pistons, engine blocks, camshafts, gears, and gear housings are all machined using CNC Milling to ensure durability and reliable performance.
d. Electrical – electronics
Enclosures, mechanical PCBs, and stamping molds for electronics are all produced using CNC Milling for precision.
e. Construction and civil mechanical works
Steel structure parts, brackets, railings, bolts, and supports—all require CNC Milling to optimize installation performance and product durability.
4. The importance of CNC Milling in modern manufacturing
In the context of economic integration and increasingly stringent product quality requirements, CNC Milling is not just a machining method—it is a vital factor for manufacturing enterprises to thrive.
Benefits that CNC Milling offers:
- Increased precision and reliability: Extremely small tolerances, uniform products.
- Higher productivity: Fast milling speed, suitable for mass production.
- Cost-saving on labor and materials: Fewer errors and less waste.
- Meets high technical demands: Machining complex shapes and hard materials.
- Eco-friendly: Less dust, noise, and supports coolant recycling systems.
Investing in CNC Milling technology is therefore an investment in sustainable growth.
5. CNC Milling process at Viet Son Mechanical
At Viet Son Mechanical, the CNC Milling process is standardized into the following steps:
Step 1: Technical requirement intake
Customers provide technical drawings, product samples, or detailed specifications. Our engineers will consult and propose the most optimal solution.
Step 2: CAD/CAM design and programming
Using CAD/CAM software like SolidWorks, MasterCAM, and NX, we design 3D models and generate CNC machining programs (G-code).
Step 3: Machine preparation and workpiece setup
The workpiece is securely clamped on the machine table and aligned precisely with the machine’s coordinate system to ensure vibration-free milling.
Step 4: CNC machining execution
The program is run automatically. Technicians monitor the operation closely to ensure safety and precision.
Step 5: Quality inspection and measurement
After completion, the product is measured using calipers, micrometers, and CMMs to ensure dimensional and tolerance compliance.
Step 6: Product delivery
Finished products are packaged and delivered to the customer in accordance with specifications and deadlines.
6. Common CNC Milling operations today
CNC Milling includes many different operations based on technical requirements:
- Face milling: For machining flat or angled surfaces.
- Groove milling: Creating keyways, circular or square slots.
- 3D surface milling: For molds and complex curved surfaces.
- Hole milling and drilling: Integrated in one setup.
- Multi-axis milling: Using 4-axis or 5-axis machines for special profiles.
Depending on the product, Viet Son Mechanical will select the most suitable machine and milling strategy to ensure optimal quality and cost.
