PCB engraving machine understanding to the copper material has its own characteristics, not only relatively soft, sticky and, in the process, we should pay attention to the use of sharp knives. PCB engraving machine to know now some carved machine tool manufacturers to generate copper data processing, especially the use of the tool of ultrafine particles of hard alloy grinding processing of the data, the effect of some good. Below for some central carved machining copper should pay attention to, including parameter setting, do a simple introduction, hope to help everyone.
1, PCB engraving machine advice to my grinding cutting tools in machining of copper material, after angle can be a little, progress of tool sharpness, but also pay attention to the front cutter surface polishing! The grinding wheel to fine particles, so as to grind a sharp tool. Sharp point, sharp point angle smaller, so that the processed effect better.
2, PCB engraving machine understanding to the characteristics of the chip breaking copper material is not good, easy to form relatively chip length, rake face so stop cutting tools must be lubricated, so can reduce the friction between the chip and tool. This is also an important match, it on the tool utilization with a relatively large influence.
3, PCB engraving machine learned in processing the red copper material, the life of cutting speed on cutting tool has no obvious influence. That is to say, in the processing of copper material, spindle speed can be adjusted to the range of relatively large. In general, the use of phi 6 flat bottomed cutter, spindle speed (RPM) in 14000 the left and right.
4, PCB engraving machine understanding to the tool overhang length should be as short as possible, or using comparative thick knife strength progress tool rod, decrease the deformation process, this point of the processed workpiece brightness with a relatively large influence.
5, PCB engraving machine understanding to the ball end cutter execute finishing two edged intersection position to be thin, this tool was sharp, reducing friction during processing. In the processing of small curvature position, processing effect is good.
