CNC machining shop with 5 AXIS. CNC milling machines with five axes are the pinnacle of milling machine expertise. They are the most expensive CNC machines to buy, and because of the complicated motions required, they require even more expertise and extra money to use the most powerful 5 axis CAM software available. However, if you have the budget for only one CNC machine, then this is the one to get.
Here are some other expensive CNC machines that you may want to consider: 3D printer (printers can also do metal working) and laser cutter.
All in all, CNC milling machines are the most expensive choice you can make as a business. They require special tools and training to work properly, so unless you have experience with these machines, it's best to hire someone who does have this knowledge.
The cost of a CNC milling machine depends on many factors such as size, capabilities, quality of materials used, etc. But we can say that they usually cost more than $100,000.
Some industries or companies may need less expensive CNC machines. Some examples are plastic parts for consumer products or simple jewelry. These types of applications require specialized tools that cost much less than full-scale CNC milling machines.
However, even though these cheaper alternatives exist, people still prefer using very high-quality CNC mills because of their accuracy and power.
The major distinction between 3-axis, 4-axis, and 5-axis machining is the degree of intricacy with which the workpiece and cutting tool may move relative to each other. The geometry of the finished machined item might be as complicated as the motion of the two pieces. If either the table or the tool head is fixed in place, it is a simple matter to describe that part of the operation as being either 2- or 4-axis depending on how many degrees of freedom there is between the moving piece and the stationary one.
A 3-axis machine has an X, Y, and Z axis that can all move in space. The tool can also rotate about these axes. A 4-axis machine adds a rotation around a third axis, usually called A. There are several ways to classify 5-axis machines. One way is by how the Z axis functions: either as a conventional linear slide (often called "slide z") or using a rotary leadscrew system. Another way is by how the A axis functions: either as a conventional rotary arm or using a linear lead screw system.
For example, a conventional 4-axis sliding-head mill uses a single spindle to perform both the cut and the revolve. It has a linear slide mechanism for the Z axis and a rotating arm for the A axis. This means that the tool can make both horizontal and vertical cuts as well as turns.
Cost of Machining The cost of machining is determined by the type of machine used. Three-axis machines and multi-axis machines are the two primary types of machines used in CNC machining. In Europe, 3-axis machines cost around $35-$40 per hour, whereas multi-axis machines cost approximately $75-$120 per hour. In the United States, 3-axis machines typically cost $80-$100 per hour while multi-axis machines range from $150 to more than $300 per hour.
The cost of CNC machining also depends on how many hours you expect the machine to run. If you need only a few parts made, a single-unit price may be all that's available. Otherwise, you can usually get a discount for buying in bulk. For example, the same 3-axis machine listed above would cost about $70 per hour if bought in quantities of 100 parts or more.
Machining time is another factor that affects the overall cost of CNC machining. Short runs of 10 pieces or less can be done in a day, while longer runs may take several days or even weeks. The amount of time it takes to make each part also determines how much you will have to pay for your CNC machining service. For example, if each part takes one hour to make and costs $10, then you could expect to spend $10,000 on machining fees alone.
