Description

品牌:国产      

含钴钻头  1.1/1.2/1.3/1.4/1.5到16柄径大量现货  适用加工304/306等不锈钢全新麻花钻

含钴钻头就是含有化学元素 钴Co
钻头原材料中,加入钴的目的是提高钻头的抗高温,抗研磨的特性,从而使钻孔达到目的.
实际操作上,一般用于加工不锈钢,铜,铝制品.这些产品的都有high tensile特性,也就是可塑性差.这些材料钻孔过程中,排出的削都依附在钻头上,为了解决这个问题,后人就发明了含钴钻,群钻等等.就像2个紧紧握住的手,非要用力拽开的话,就得在分离处,不断的扣,磨.这样,高温就产生啦.普通钻头一遇高温,急速膨胀,钻柄部不断施加的扭力就让钻头本身断掉,或者钻尖翻遍不能用.
简单一句话,含钴钻就是加入了化学元素钴,用来切削高研磨,容易产生高温金属的高速钢钻头.
