What You Need to Know About CNC Machinery for Sale
The CNC machinery for sale in the market is more complex in their working and application than they appear. A lot is going on inside these machines that you need to know to understand better what they are and how they work. For an in-depth understanding of these machines, you need to understand some basic terms about them first. These terms will make it easy to understand the functioning and working of complex CNC machines.
The important and basic terms to understand about CNC machines are listed below:
CNC has to be the first term to understand because this term is all the equipment is based upon. The abbreviation stands for Computer Numerical Control. It makes it clear that this machinery is operated by computers using numbers. Input is given through codes in numbers and letters, called the G-code. Computer languages process these codes to provide an output.
- Desktop CNC
As the name depicts, the desktop CNC machines are also computerized machines used to cut different materials and create shapes. However, these machines are smaller in size and work on softer and less rigid materials like plastic, foam, and wax. Desktop CNC may also use G-code to function and draw shapes on and out of different materials. You can find countless desktop CNC machine shops in Georgia to get your desired tools.
The term CAM stands for Computer-Aided Machining. CAM refers to creating the Numerical Control (NC) codes (G-code) through different software. The CNC machinery then processes these codes to provide an output. An expert must run the CAM programs and create G-codes that will result in different shapes created by CNC machines.
Axis points of CNC Machinery for Sale
All the CNC machines available for industrial or domestic purposes use different axis points to function and create shapes. Most machines have three axes, but advanced ones may have four or five to create shapes with multiple dimensions.
These axis points are explained below:
- 3 Axis
We’re all familiar with the three primary axes, such as the X, Y, and Z. 3 axis machining means that the machine cutter uses the XYZ axes to create the shape, while the workpiece remains static at its position. This type of machine work is used when there is no need to add depth to the shapes created. Most CNC machinery for sale uses 3 axis machining.
- 4 Axis
The fourth axis added to CNC machining refers to the A axis. This axis is created when the workpiece rotates around the X-axis to allow the machine to make holes or cuts to the side of the material while it rotates. The cutters, in this scenario, work on the opposite axis of the one creating the rotations. It is called the B axis.
- 5 Axis
The 5 axis machining is the most advanced and complex one. It refers to the automatic movement and rotation of the workpiece along 5 of the total 6 axes. The workpiece moves along the X, Y, and Z axes and will rotate around any two of the A, B, and C axes. These types of advanced procedures are used in the automobile and aerospace industries.
