The grinding tool is a work that needs patience, time, skill and even talent. Even if the fixed angle grinder is used, it can only solve the problem of fixed angle (the most difficult technology in the grinding tool technique). However, all other requirements can not be less, and patience, time and correct operation method are still needed to grind out sharp and durable tools.
Whether it meets the technical needs of sharpening is the best standard to test the quality of the sharpener, not in terms of simplicity or complexity. The fast sharpener is the simplest, but its essence is scraping rather than grinding. The effect is very poor, the sharpness is close to rough grinding, and the retention is even worse.
Because of the consideration of efficiency and workers’ technical problems, large factories changed their cutting tools to machine clamping tools long ago, so it is difficult to see lathe workers sharpening tools. Some lathe workers even think that sharpening is very dirty and hard, and secretly change the cutting tools to machine clamping tools. I don’t know that this kind of replacement makes them lose the opportunity to practice their skills and deeply understand the cutting tools. If you don’t have the basic knowledge of tool understanding, then you can’t choose the right clamping tool and blade.
Turning tool grinding is a basic operation with high technical content in cutting. The operator needs to be familiar with the relevant theoretical knowledge and grinding principle, and master the grinding method and operation skills.
