金属切削机床的过载保护是保护电动机的过载,在有些机床中,还要对加工的刀具进行保护,如刀具铣床。多数刀具过载破损时,电机并没有过载。刀具损坏不仅使成本提高,效率降低,严重时还会使机床的部件损坏,使机床的精度严重下降。因此,刀具过载保护对于这类机床显得十分必要。 这类 Metal cutting machine overload protection is to protect the motor overload, in some machines, but also to protect the processing of tools, such as tool milling machine. The majority of tool overload is damaged, the motor is not overloaded. Damage to the tool not only increases the cost and reduces the efficiency, but also damages the components of the machine in severe cases and seriously deteriorates the precision of the machine tool. Therefore, tool overload protection for this type of machine is very necessary. This class
