Things You Need to Know About Five-Axis CNC Machines

21 February 2020

CNC is an abbreviation for computer numerical control, and the machines of this style need preset requirements created by specially designed software to accomplish their tasks effectively. Many turn to CNC for milling processes since the machines use a subtractive technique to cut away material systemically to bring about the intended results. It is important to note, though, that these machines can do more than just milling, depending upon their design. While the most well-known versions of these machines are three-axis and four-axis ones, there also are advanced five-axis versions. It is the latter one that we will be explaining in this information.

Definition of Five-Axis CNC Machines

Five-axis CNC Machines add two additional axes to those of a three-axis models, which are based on the Cartesian Coordinate system of X, Y and Z. The other two axes are A and B, and A rotates around X while B rotates around Y. With these additional axes, the five-axis versions of the CNC machines can make more complex objects without the multiple setups required on the machines with only three or four axes. Also, accuracy is higher due to the fact that you do not need to stop to readjust the five-axis machines during the CNC process to prepare for the next stage. Material removal proceeds at a faster rate too, which cuts down on labour costs.

Types of Five-Axis CNC Machines

• One type of these machines moves the table with the material on it to utilise the two additional axes. This method has great speed and stability but cannot perform its functions effectively with overly heavy or large blocks of material.

• The other type of the five-axis CNC machines uses a swivel toolhead that moves around the block of project material to perform its tasks. It can reach into tight spaces and deal with overly heavy or large material blocks more efficiently than the above type of machine can with projects.

Materials Used in Creating Projects With These Machines

Examples of the materials that these machines utilise to make projects are as follows:

• Plastics
• Stainless Steels
• Steels
• High-Tensile Tool Steels
• Hard-Machining Metals
• Alloys
• Exotic Materials

Note here that you need to select the material that best suits the desired project.

Advantages of the Five-Axis CNC Machines

• Faster turnout that saves labour time and costs
• Lower vibration of the toolhead since it can use shorter tools in comparison to the three-axis and four-axis CNC machines
• Can accomplish complex shapes and projects with a single setup.

Analyse your project closely to decide which CNC machine is right for your purposes. Do not hesitate to trust the outcome of the five-axis CNC machines, as they turn out precise results quickly and efficiently.
