Warm Prompt
1.Machine tools must be reliably grounded;
2.The normal operation of machine tools must be checked before parts are processed;
3.Only after clamping fixture and cutting tool are pressed, can the working cycle be executed;
4.Do not touch the rotating and moving parts of the machine tool during operation;
5.Attention should be paid to spatter of cutting objects and cutting fluid when machining workpiece.
