以汽车为首的众多机械零、部件需要切削加工,为易于切削材料,广泛使用添加了铅的易切削钢。不过,在制造业中,考虑到对环境及人体的影响,逐渐开始限制铅的使用,对切削油剂的使用要求也不断提高。为满足这类要求,必须有新的易切削钢,来代替含铅易切削钢。人们正在进行易切削钢的
A large number of automotive-led mechanical parts and components require cutting, making it easy to cut materials and widely used lead-free cutting steel. However, in the manufacturing industry, taking into account the impact on the environment and the human body, the restrictions on the use of lead gradually come to the fore. As a result, the requirements on the use of cutting oil are also constantly increasing. To meet these requirements, there must be new free-cutting steel to replace lead free cutting steel.
