Description

technical field [0001] The invention relates to the field of metal substrate processing, in particular to a cast iron drilling device and a drilling method thereof under the condition of internal cooling and low-temperature micro-lubrication. Background technique [0002] Cast iron is gradually being widely used due to its excellent tensile strength, fatigue resistance, elastic modulus and wear resistance, as well as excellent casting performance and thermal conductivity. The excellent performance of cast iron ensures that it can maintain sufficient strength at high temperatures. [0003] The excellent physical properties of cast iron make its machining performance even worse. In the process of cast iron processing, the cutting force required by the machine tool and the cutting force received by the tool are relatively large; the cutting temperature is high during the cutting process of cast iron materials, and the cutting heat is more likely to accumulate during the proces...
