I operate the engraving machine. The boss told me to process 8 PCB boards. How do I always break the milling cutters?. What do you want to do? Would you like to ask if there are 4.5 PCB cutters? Thank you
Don't mill 8MM deep once you're milling! Divided into several milling will not cut the knife!
The quality is not good. As long as you can out of money, what can be the cutter specifications that can use Baidu Search CYC tungsten steel milling cutter. Find their contact information, Mr. zheng. Ask him about the technical problems in this area, and although their company doesn't sell PCB cutters, there are people in their circles who sell it.
The broken bladeThe 1 reason is that the moving speed is too high, causing the lateral force to be too high. Solution: properly reduce speed (recommended) if you do not change the moving speed is increasing rotational speed (not recommended) 2 movement speed is normal, but the rotation speed is too low solution: increasing rotational speed. 3 blade diameter is too small, easy to break. Solution: start processing at the slowest (moving speed) start, and then gradually upgrade, the final moving speed should not be too fast.The chip is not goodCause 1 rotation speed does not correspond with moving speed. Solution: proper adjustment of machine speed setting. Cause 2, the tool structure and material properties do not agree with each other. Solution: switch to other types of tool testing. Cause 3 tool structure wear or not. Solution: tool use time is too long or wear, replace new tool.6, the quality of engraving knife is too bad.7, the engraving knife installation is not standard, the handle is exposed too long.
