How to eliminate the clearance of precision boring tools in machining center! It's fine-tuned
No matter how fine-tuning your fine boring cutter is, it is difficult to control the size of 1 line by fine-tuning the boring cutter. In this way, 0. 1-0.2 material and 0. 1 hard material can be left when machining fine holes. First try to cut the tool with a certain depth, and check that the size is suitable. Repeat this action twice, and you can master the characteristics of the boring tool you are currently using, and remember the last tool. The allowance cannot be too much or too little. It is necessary to distinguish the material of the workpiece from the accuracy of the HRC joint hole of the boring tool (blade). When testing the tool, the size change of the hole should be increased or decreased appropriately. Adjust the fine adjustment knob of the fine boring cutter, and strive to sum up small and medium-sized experience in daily work. I believe I will soon become a master of holes.

Generally, it is troublesome to reduce the last hole by 0.0 1. Fine-tuning is useless. If it is not adjusted, the knife just now will be 0.02-0.03 larger and the hole wall will have a spiral line. Sometimes the size of the hole doesn't change. There is a way to draw on the top of the hole with colored ink pen, and check whether your blade will turn the knob (0. 1-0.2) several times, and then enter your original position by 0.066 less.

Follow the principle of adjusting backward first to eliminate the clearance of honing tools, and then test the tools before cutting to ensure the dimensional tolerance. If you have some experience, you can also adjust honing tools and change cutting parameters, such as adding or subtracting RPM feed. 0.0 1 is also acceptable. Generally, the last tool is directly within the tolerance range of 30+0.005. The key is that you should gradually get familiar with the honing accuracy of your machine tool. When you process holes, you should adopt appropriate technological methods, such as fine and coarse allowance, arrange the cutting process reasonably according to the HRC diagram of the material blade, pay more attention to detection and observation, and accumulate some skills.

I wrote a lot of hope to be useful to you. Everyone started doing it. Now I'm switching to Shanghai, and I'm going to do a clothing business that I haven't done before. I also hope to see friends passing by. If they have experience in clothing business, please contact me at QQ:295255042.
