双料两路冷却法是一种在磨削中已有过简单先例的技术概念。而现在在各种类型磨床上,所常用的冷却方法却是从外部,并只用一种冷却液来进行的。 在新的方法里是通过两条道路,一方面是通过外部冷却,另一方面是通过砂轮的内部冷却,并使用两种不同的冷却剂,外部冷却使用通常的冷却剂 The two-pass two-pass cooling method is a technical concept that has been a simple precedent in grinding. And now in all types of grinders, the commonly used cooling method is from the outside, and only one kind of coolant to carry out. In the new method, two roads are passed through on the one hand by external cooling and on the other hand by internal grinding of the wheel and by the use of two different coolants and external cooling by the usual coolant
