Stone CNC router, as an important stone engraving equipment, has made the interior decoration more artistic, high-end and large-scale owing to their advantages of advanced functions, higher automaton and working efficiency, thus they are getting more popular among people involving in stone & marble processing. However, many different kinds of stone cnc router machines are available which have quite different working performance and functions, it becomes even harder for those fresh new hands, what factors should be paid attention to when choosing a stone engraving machine? Here we briefly discuss some points for you.
1). The quality & performance of the spindle motor: The spindle motor is generally not covered by the warranty and the spindle motor works continuously for a long time, so if the spindle motor is not good, It will also affect the use of engraving machines.
2). The function of marble stone engraving machine: The spindle motor of the engraving machine has high power and low power. Some engraving machines with low power are only suitable for the processing of materials such as two-color plates, architectural models, small signs, three-dimensional crafts, etc. This technology has been popular for some time, but the engraving power is too small and its application range is greatly affected. Another kind is the stone engraving machine with a high-power spindle motor. This engraving machine is mainly divided into two categories: 1, granite engraving machine with large-format working size: the working size is generally more than one meter, but the accuracy of this engraving machine is generally poor; 2, stone engraving machine with moderate and small working size: this kind of engraving machine is generally used in fine processing and organic sign production.
3). The speed adjustable range of spindle motor: Generally, the adjustable range of speed is several thousand to 30,000 revolutions per minute. If the speed is not adjustable or the adjustable range of speed is small, then the application range of the stone engraving machine will be affected, because different materials must be engraved with different engraving head speeds.
4). The manufacturing process of machine body: The machine body must be precise and stable when the high-power stone engraving machine works. Therefore, the long-term and high-power engraving requires a cast bed or at least a cast table to ensure its processing accuracy and stability.
5). The control system: the controllers are generally divided into two categories: the first type of controller is just for driving and all its calculation work is completed by computer. When the stone engraving machine is under working, the computer is in a waiting state and cannot perform typesetting. Another type of controller is controlled by a single-board computer or a single-chip computer. This controller is actually a computer, so as long as the engraving machine starts to work, the computer can immediately perform other typesetting work, especially when engraving for a long time. The advantages are particularly obvious.
6). The quality and precision of screw rod and guide rail: The screw rod and guide rail are also an important part of stone engraving machine. A good screw rod and guide rail are the guarantee of the accuracy and performance of the engraving machine during long-term use.
The above six factors should be taken into consideration when choosing a stone engraving machine, sincerely hope it will be helpful to everyone.
