II. Types of CNC Milling Machines at Viet Son Mechanical
At Viet Son Mechanical, two common types of CNC milling machines used are the 3-axis CNC milling machine and the bed mill:
1. 3-Axis CNC Milling Machine:
This type of milling machine features three moving axes: X, Y, and Z. These axes allow for machining on flat surfaces, cavities, and grooves.
The 3-axis milling machine is suitable for machining simple to medium complexity parts, often found in products that require precision but are not overly complex.
Advantages: Easy to operate, high precision, time and cost-efficient.
Applications: Machining flat parts, cavities, and grooves in the fields of mechanical engineering, healthcare, electronics, and automotive.
2. Bed Mill Machine:
This is a large milling machine with high load capacity and power. The table is fixed, with only the spindle moving, which helps reduce vibration and increase stability.
The bed mill is ideal for large, heavy, and complex parts that require high precision, commonly used in mold making and machining large components.
Advantages: High load capacity, stable, durable, suitable for machining large parts.
Applications: Machining large, heavy components such as frames and molds in the automotive, aerospace, and shipbuilding industries.
Both types of milling machines help Viet Son optimize efficiency and quality in machining projects, meeting the diverse requirements of customers.
III. CNC Milling Machining Process
The CNC milling machining process is an automated production method controlled by a computer, designed to create precise mechanical components from various materials such as metals, plastics, or alloys.
- Designing Technical Drawings (CAD – Computer-Aided Design):
- The first step in the process is to design detailed drawings of the component to be machined using CAD software (such as AutoCAD, SolidWorks).
- Characteristics: Drawings are typically in 2D or 3D format, containing complete technical specifications regarding dimensions, shapes, and technical requirements of the part.
- Machining Programming (CAM – Computer-Aided Manufacturing):
- After obtaining the CAD drawing, the CNC technician uses CAM software to convert the design into control codes for the CNC machine, usually G-code and M-code.
- G-code: Used to control the position and speed of the cutting tool.
- M-code: Used to control machine functions such as turning on/off, tool changes, and coolant pump operation.
- Preparing Material and Setting Up the CNC Machine:
- Prepare raw material (metal, plastic, alloy) and securely fix it on the CNC machine table using vices or clamps.
- Install the appropriate milling cutter and calibrate the origin coordinates on the material for the machine to identify the cutting start point.
- Check machining parameters (spindle speed, feed rate, cutting depth) in the control software to ensure precise cutting.
- CNC Milling Machining:
- Starting the CNC Machine: The machine will perform machining based on the programmed codes, controlling the cutting tool to move along the axes (X, Y, Z) for cutting and shaping the product.
- Material Cutting: The machine removes excess material from the workpiece in small layers, creating the desired shape and size according to the original design.
- During this process, coolant is often used to reduce temperature, extend the lifespan of the cutting tool, and ensure a smooth machined surface.
- Product Inspection and Finishing:
- After machining, the product is inspected for dimensions and shapes using measurement tools to ensure compliance with technical standards. If necessary, the product undergoes finishing processes such as polishing, heat treatment, plating, or painting to enhance durability and aesthetics.
- A comprehensive quality check is performed before delivery.
- CNC Machine Maintenance:
- After machining is complete, regular maintenance for the CNC machine is required, such as cleaning, checking cutting tools, and inspecting the control system to ensure the machine operates smoothly and maintains high performance for future machining tasks.
The CNC milling machining process ensures precision, efficiency, and the ability to produce in bulk, meeting the high technical demands of the mechanical engineering industry.

VI. Factors Affecting the Quality of CNC Milling Machining
The quality of CNC milling machining is influenced by several factors:
Material Quality: The properties of the material (hardness, strength, ductility) affect the cutting ability and precision of the final product. Different materials require different machining parameters.
Cutting Tools: The quality, shape, and sharpness of the cutting tools are crucial. Worn or inappropriate tools can lead to errors and unsatisfactory surface finishes.
Spindle Speed and Feed Rate: The spindle speed and the cutting tool’s feed rate need to be adjusted according to the material and tool type. Incorrect speeds can lead to overheating, rapid wear, or poor surface finish.
Machining Equipment: The accuracy and stability of the CNC milling machine significantly impact product quality. Old or poorly maintained machines can cause errors during machining.
Control System Accuracy: The programming software and CNC control system need precise calibration. Errors in commands or programming can result in cutting discrepancies.
Workpiece Setup: Properly securing the workpiece on the machine bed is critical. The workpiece must be securely fastened to prevent movement during machining, which affects precision and product quality.
Coolant Usage: Using the appropriate coolant helps lower temperatures during machining, extends tool life, and ensures a smooth surface finish.
Quality Control: Implementing quality checks at each machining stage helps detect issues early and allows for timely adjustments, enhancing the quality of the final product.
These factors must be managed and optimized to ensure product quality in CNC milling machining, effectively meeting customer requirements and technical standards.
