With the continuous development of the blade material, the shape of the blade is constantly changing. Starting is the overall tool, and then after the hard alloy blade is set in the blade, the blade is fastened to the blade, and so on. Blade repair also immediately appear market.
The machine blade is a method that will have an effective cutting edge of the whole super hard blade with a machine stake in the original knife or knife body and use, if the effective cutting edge all repair grinding, discard the need, that is, as a blade to use. Especially with the popularity of CNC machine tools, indexable inserts can accurately determine the tip position, or need regrinding and the labor-saving aspects made a great contribution, and improve the productivity. However, simply discard unused, from resource limited this consideration, there is a need to save resources was studied in a meat grinder blade found. So the blade grinding is a very economical performance.
Super hard alloy manufactured by powder metallurgy method, with higher speed and higher efficiency on cutting harder materials has become possible, to prevent the emergence of the now of artificial diamond and cubic boron nitride (Pian (CBN) etc. sintered tool. The material of the blade is more difficult to do, blade grinding is also difficult.
On the other hand, compared with the super hard blade material, so-called steel to improve the performance of the re valuation. Know the meat grinder blade in material, Fenggang is divided into tungsten and platinum, variety, a wide range of uses, especially widely used in forming cutter and super hard alloy in low speed range of the existing shortcomings in the field of. Because of the blade material, shape and type of trouble, the condition of the blade repair is also different. Therefore, knowledge about the blade material, tip shape, grinding wheel selection and blade repair grinding method seem more and more important.
