4-axis CNC milling machines with outstanding capabilities are increasingly being used in factories and mechanical workshops. The machine can process 4 sides of workpieces, products with complex shapes, requiring high precision. The machine is applied in many fields such as manufacturing machine parts, aviation, aerospace, medical, automobile equipment,…
1. What is a 4-axis CNC milling machine?
4-axis CNC milling machine is a milling machine used to process and cut machine parts with advanced CNC technology. The difference compared to other CNC milling machines is the mechanism that operates on the axes. The machine is supplemented with an A axis that rotates around the X axis. The addition of a fourth axis allows the workpiece to move, rotate, and flip as desired. This makes it possible for the machine to machine 4 sides of the part to be machined by flipping the workpiece.
The operating principle of a 4-axis milling machine depends on the design of the machine parts. For machines with workpieces moving in X and Y axes, after activating the machine, the main shaft will move in the Z direction up and down. Meanwhile, the machine table holds the product and moves along the X and Y axes. Combined with the Z axis to bring the cutting knife to the areas where the product is desired to be processed. Axis A has the ability to hold the workpiece and let it rotate as desired. To meet processing requirements such as products with round cylindrical surfaces, etc.
All machine operations are performed using CNC codes such as moving axes to a specific position, cutting speed, cutting depth, opening and closing the main axis, etc. The structure of a 4-axis CNC milling machine is similar to that of a machine. 3 axis CNC milling.
2. Uses of 4-axis CNC milling machine
The addition of the A axis gives the 4-axis CNC milling machine more processing capabilities, specifically:
- Capable of cutting workpieces at many angles (4 sides). Because axis A will hold the workpiece and make it rotate as desired.
- Placing the workpiece or resetting the coordinate origin is simpler than with a 3-axis CNC milling machine.
- Minimize errors as much as possible.
- Can process products with complex shapes and require high precision.
- The machine has greater flexibility, moves many arcs and can process more angles.
- Longer tool life, helping the machine operate longer.
3. Application of 4-axis CNC milling machine
The machine has higher precision machining capabilities than conventional milling machines, so it is widely used in mechanical processing. Besides, the machine also produces products in many other fields such as:
- Processing details, JIGs, products according to the special or unique needs of each customer. Create a series of 100% identical products.
- Production of household appliances: thanks to the machine’s stable operation and ability to produce goods. Create a large number of similar products.
- Manufacturing all kinds of motorbike and car parts and machine parts.
- Production of medical and technological equipment.
- Mold processing.
- Dies for jewelry, punching, coins, embossing, etc.
