performance index of diamond tools : 1 、 硬度可达8000HV , 为硬质合金 的80 120倍 ; 1 , the hardness is up to 8000HV , the hard alloy of 80 -- 120 times ; 2 、 导热系数为 700W/mK ,
 performance index of diamond tools:


1硬度可达8000HV为硬质合金的80——120倍

1, the hardness is up to 8000HV, the hard alloy of 80 -- 120 times;


2导热系数为700W/mK硬质合金的1.5——9倍甚至高于PCBN和铜所以热量传递更迅速

2, the coefficient of thermal conductivity for 700W/mK, as the hard alloy of 1.5 -- 9 times, or even higher than that of PCBN and copper,so the heat transfer more quickly;


3摩擦系数一般仅为0.1——0.3硬质合金的摩擦系数0.4——1因此可显著减小切削力

3, the friction coefficient is only 0.1 -- 0.3 ( friction coefficient ofcemented carbide is 0.4 -- 1 ), it can significantly reduce the cutting force.


4热膨胀系数仅为0.9×10 -6——1.18×10 -6仅相当于硬质合金的1/5因此CDW20牌号金刚石刀具热变形小加工精度高

4, the thermal expansion coefficient is 0.9× 10 -6 -- 1.18× 10 -6, only the equivalent of cemented carbide 1/5, so CDW20 grade diamond tool thermal deformation is small, high precision machining.


5刀具与有色金属和非金属材料间的亲和力在加工过程中切屑不易粘结在刀尖上形成积屑瘤

5, the tool and non-ferrous metals and non-metallic materials affinity between the very small, in the process of processing chip is not easy to bond on the tip of built-up edge formation.


结语CDW20牌号金刚石刀具不但硬度高而且韧性优异,不但解决了使用传统刀具不耐磨的问题而且解决了金刚石刀具由于脆性大而经常崩刀的问题车削玻璃钢时, CDW20牌号金刚石车刀具呈现出刀具耐用度高车削光洁度高加工效率高的特点

Conclusion: CDW20 grade diamond tool not only high hardness, andexcellent toughness, not only solved using traditional tools do not wear problem, but also solve the diamond tools because ofbrittleness and often (Editor:admin)
