Why does the PCB milling cutter cut off the additional milling cutter? In the case of taper OK, why is the depth of the front and the last section different from the angle?
If the tool hardness is guaranteed, if it is easy to break, the tool with a good toughness should be used, and the amount of cutting is also the factor that causes the breaking of the knife.
If your milling angle is exactly the angle of your workpiece, then you don't need to have any direct feed
Will the cutter be broken or is it still in the process of the Gong plate?If the lower cutter location fracture, mainly the milling cutter falling speed is too fast and the spindle speed is too low;The cutting process of Gong board is caused by insufficient cutting. The possible reasons are divided into three parts: parameter, folding board and dust absorption effect.Parameters are mainly low speed, too fast plate speed;In the aspect of stacking, the main reason is that the thickness of the laminated plate is too high, the milling cutter is seriously worn out, and the effect of dust removal is poor;The main effect of dust absorption is that the dust in the chip can not be sucked away in time, leading to fatigue wear of the milling cutter.Different plate milling cutter choice also has relations, generally FR-4 milling cutter commonly used 0.8, 1.0mm, ceramic plate milling cutter with 1.0mm or above, life expectancy will be much shorter than FR-4.Processing milling cutter depth, angle is different because the amount of dust exhaust is different, as long as the contrast with the new milling cutter is not a big difference.
