Cemented carbide is a special metal. The hardness test of cemented carbide can reflect the difference in mechanical properties of cemented carbide materials under different chemical composition, structure and heat treatment process conditions. Therefore, the hardness test of metal materials is widely used. Carbide performance inspection, supervision of the correctness of heat treatment process and research of new materials.
When placing alloy cutters, the firm bolts should be tightened in sequence and evenly. However, the bolts should not be tightened too tightly, otherwise it will lead to the absolute prohibition of the placement of the turning tool. The length of the cutter head protruding from the tool holder should be small even if it extends beyond the permanent robbery (L) 2H), it will cause the alloy cutter to vibrate, thereby destroying the alloy sheet, and otherwise, it will also reduce the cutting amount. When external turning, the positioning of the turning tool, the tool tip should be exactly the center line, at least not higher than the diameter of the workpiece 0.01 mm, and when boring, the center should be accurately aligned.
Nowadays, diamond knives are widely used in industry, and diamond knives are very popular. This is because diamond knives have the advantages of high hardness, good cutting effect, fast heat conduction speed and long durability. Let's take a look at the classification of diamond knives! Diamond knives must be made of diamonds, but they are not pure diamonds. We all know that they are industrial diamonds.
Diamond knives are rare in our lives, but they are indeed widely used in industrial processing today. Let's take a look at the problems of diamond cutting tools in processing. We all know that in addition to the size requirements, there is a very important requirement for diamond cutting tools that there is no chipping in the cutting edge. What we call no chipping means that no chipping can be seen under the condition of 500 times magnification. We can detect the size problem directly with professional tools. Now let’s talk about collapse:
