Must pay attention to the PCB engraving machine engraving process

1) PCB engraving machine to chuck is intact, and be clean and free of foreign body. If there is any a little damage on the chuck, will be uneven deformation occurs in the clamping deformation process, ultimately increasing the cutter runout. Impact of the dust on the chuck is large, it is very easy to overlook. Because the dust will increase the cutter runout position, after a lot of experiments show that, there will be a chuck clean dust clean, radial runout distance can be reduced about 50%! The corresponding tool life can progress to more than 2 times.

2) PCB engraving machine can brief tool overhang length, but also to ensure the cleanliness of the standard tool. The tool length, by cutting force in the same condition, the cutter deflection is big, this also increases the cutter runout, reducing tool life. At the same time, if the tool overhang length is large, the brightness will influence the processed, and in this respect is very big. The tool also should pay attention to cleanliness, cutter dust and chuck the dust on the same effect on the radial runout, it will affect the tool life by greatly.

3) with the PCB engraving machine to tool and chuck. In the clamping tool to chuck had begun after deformation, and then into the tool, it can reduce the radial cutter runout. In addition, pay attention to the dynamics in the clamping, clamping force is not the bigger the better, the experimental research, the clamping force reasonably can reduce the cutter runout 20%. This operator clamping force machine tool demand reasonable I stop to summarize, a lot of experiments, I find my clamping tool.
