Engraving machine how to choose the circuit board?

First, the maximum size of the PCB is marked by the maximum PCB, which is limited by the size and rigidity of the hardware. General machine design, consider the one hand, the circuit board area is rarely done, and the other is too large format will make the hardware deformation, so mostly in the 300mm square. Most of the platform is made of cast iron or aluminum to ensure the strength and rigidity.

Fourth, high speed spindle, drive tools like a sharp sword cut melon, milling line pretty neat, good effect. But the high speed at the expense of the service life of the motor, with a motor in the calibration range of speed, the speed is doubled, the life is reduced by half, so does not speed as high as possible, but to achieve an ideal value can be.

Third, the maximum operating speed refers to the speed of the X, Y axis movement. In fact, the circuit board engraving process, the circuit board engraving machine speed is very low, then why should we emphasize this indicator? A high speed represents the driving ability of the motor, which allows it to move fast, it can make a quick stop, on the other hand also represents the assembly track, screw parallel relationship, small damping, will not affect the accuracy.

Second, the minimum line diameter and line spacing can be used to represent the accuracy of the machine. Most people here have a misunderstanding, only to see the minimum diameter of the role, but ignored the minimum line distance, in fact, the smallest distance represents the level of the machine. The minimum diameter is determined by the location of the tip. Even if the tip is biased, you can also choose to repair the tool on the numerical value. The minimum line distance cannot do hide, even if only 0.1mm wide point, in motion control is not good and the swing, will make the tool through the traces become very wide, the two very nearly every line all off. At the time of purchase can also be through this indicator, to understand the control of the product and assembly level.
