Hello everyone FRIENDS! You are watching the channel Merry Engineer.
I think it will be useful for you to know what a tool coating is. This is not only a pleasant and beautiful color of your drills, cutters, milling cutters, etc., but the main purpose of the coating of the cutting tool is to extend the life of your cutting tool as much as possible. The enterprises of our country use various types of tool coating. Of course, we will not consider everything in this video tutorial, since there are a lot of them. We can only say one thing: protective coatings of the tool increase the durability of the cutting tool by 4-6 times and this is not a joke, but quite real test results. In order for the application of coatings to the tool to take place in the normal mode, it is necessary to have special equipment and components. Depending on the color of your tool, you can roughly determine what wear-resistant coatings of the tool were applied to yours. All over the world, wear-resistant coatings of cutting tools are used after each resharpening of the cutting tool and without its application, they do not start work. From here, since this direction is developing intensively, the types of coatings of the cutting tool are multiplying very intensively. The equipment for applying wear-resistant coatings, both on the cutting tool, and wear-resistant coating of metal will help to extend its service life many times over, is also very diverse. Therefore, as a cheerful engineer, I recommend that you do not neglect this benefit of technological improvement of the tool and it is MANDATORY to make a coating for the tool!
