一、前言切削液可分为油剂和水剂两大类。水剂切削液大致又可分为乳化型、无机盐溶液(象苏打水这种类型)及化学合成型三种类型。乳化型切削液有较好的润滑性能,一般5%的乳化液的最大无咬卡负荷 PB 值在50公斤以上,极压乳化液可高达100公斤以上,加之冷却性比油剂好,又有一定的防锈能力,因此广泛的用于磨削、车削、钻孔、攻丝、拉削等加工。但存在 First, the foreword Cutting fluid can be divided into two major categories of oil and water. Aqueous cutting fluid can be roughly divided into emulsified, inorganic salt solution (such as soda type) and chemical synthesis of three types. Emulsion type cutting fluid has better lubricating properties, the general maximum 5% of the emulsion without bite card load PB value of 50 kg or more, extreme pressure emulsion can be as high as 100 kg, combined with cooling than oil, and A certain degree of anti-rust, it is widely used for grinding, turning, drilling, tapping, broaching and other processing.
