三用硬合金刀施工硬合金的制成从炭素工具钢发展到合金高速钢,我们得到了较高的热硬度(Warmharte)以及耐磨性。但若要使这样的刀具达到一定的寿命,切削进行时的温度不得超过540℃。为了更进一步提高切削速度的努力结果,又发现了一种新的刀具材料。它含有大量金属炭化物与重炭化物,具有显著的自然硬度,因而发挥很高的切削性能,且超过了使用高速钢刀具切削峙所能承受的温度。起初由熔解制成的硬合金,因为它很容易脆断,以及对工件产生的振动很敏感,现在已经不再
Three-hard alloy knife construction hard alloy made from the development of carbon tool steel to alloy high-speed steel, we get a high hot hardness (Warmharte) and wear resistance. However, to achieve such a tool life, the cutting temperature should not exceed 540 ℃. In order to further improve the cutting speed of the efforts of the results, but also found a new tool material. It contains a large amount of metal carbides and heavy carbon compounds, has a significant natural hardness, which play a high cutting performance, and exceeds the use of high-speed steel cutting tools can withstand the temperature. Initially made of molten hard alloy, because it is easy to brittle fracture, and the vibration of the workpiece is very sensitive, and now no longer
