Hundreds of CNC machines are available in the market, and their price varies depending on several factors. The most expensive ones are 6-axis and 5-axis robotic CNCs that are widely used in manufacturing high-quality military equipment, and entry-level hobbyists can also get an affordable cnc router machine costing as low as $150. Regarding economic CNC machines, most dealers are open to negotiation, and a person can choose from several options. This article explains different factors affecting CNC machines’ cost.
- Size of the CNC Machine
The size of the CNC routing machines is determined by the length that the cutting end could travel along the XYZ axes. The shorter the range, the smaller the machines will be, and one can get a more affordable cnc router machine.
- Machining Speed
The cutting speed of a CNC machine directly affects the product’s efficiency and the quality of finished goods. Furthermore, faster speed results in smoother finishes and quicker and more efficient production.
Another factor in CNC machines’ speed is the Rapid Motion speed. It can be defined as the rate at which the machine repositions itself after cutting the material. The more Rapid Motion speed, the faster the CNC machine will complete multiple tasks. A manufacturer can even purchase CNC machines having a Rapid Motion speed of over 1000 inches per minute.
Usually, the faster a CNC machine can reach the maximum machining speed and the Rapid Motion speed, the more will be its cost.
- Number of Axes
The cost of a CNC machine and degrees of freedom is directly related. Simply put, the more the CNC routing machine is equipped with the degrees of freedom, the higher will be the machining cost.
For instance, a 5-axis CNC machine costs more than a 3-axis CNC machine. A hobbyist mostly prefers an affordable cnc router machine equipped with a 3-axis.
- Machining Tolerances and Accuracy
The price of CNC machines offering higher machining tolerances and accuracy will be on the higher side as accuracy and perfection come with a cost.
- Power
The brute power of the CNC machines is measured in terms of the spindle and the torque they can handle. However, larger professional CNC machines are priced based on the size of their servo motors.
For instance, the stepper motor of a hobbyist CNC machine runs at around 0.18 to 0.20 ft-lb, while a professional 6-axis CNC routing machine will run at 68 ft-lb. That said, the latter machine is approximately 400 times more formal than the former one. As a result, the hobbyist CNC machine will be way less expensive than the 6-axis CNC.
Conclusion
Knowing different factors affecting the CNC machining cost will help an individual choose an excellent, affordable CNC machine. The price varies with different categories of CNC machines. If one is shipping the CNC machines, in addition to the above-discussed factors, shipping charges and taxes will also affect their cost. The manufacturer can get a good CNC routing machine, specifically for engraving purposes, at less than $10,000, especially if he has just started the business and requires a machine for low production volume.
