The significance of drilling drives the development of society. It plays an important role in the manufacturing industry, providing essential parts and processes for various industries. It is with the application of machine tool drilling technology that we can enjoy modern life and convenience.
The process of drilling machine tools needs to go through a strict process flow. First of all, we need to choose the right machine tool equipment, according to different requirements to choose different drill bits. Then, we need to adjust the speed and force of the machine to ensure the accuracy and stability of the drilling. Finally, we also need to use coolant to reduce the temperature, to ensure the life of the drill and the quality of the drill hole.
Drilling requires a rigorous process. First of all, we need to choose the right machine tool equipment, according to different requirements to choose different drill bits. Then, we need to adjust the speed and force of the machine to ensure the accuracy and stability of the drilling. Finally, we also need to use coolant to reduce the temperature, to ensure the life of the drill and the quality of the drill hole.
As the most common tool in hole processing, drill is widely used in mechanical manufacturing, especially for the processing of parts such as cooling devices, tube plates of power generation equipment and steam generators, etc., the application is particularly extensive and important.
First The Characteristics Of Drilling
The drill usually has two main cutting edges, and when machining, the drill is rotated at the same time. The front Angle of the bit becomes larger and larger from the central axis to the outer edge, and the cutting speed of the bit is higher the closer it is to the outer circular part, and the cutting speed decreases to the center, and the cutting speed of the rotating center of the bit is zero.
According to the shape of the workpiece, material, structure, function, etc., the drill can be divided into many types, such as high-speed steel drill (twist drill, group drill, flat drill), integral carbide drill, indexable shallow hole drill, deep hole drill, casing drill and interchangeable bit.
Second Chip Breaking And Chip Removal
The cuttings removal of drilling machine refers to the operation of removing the cuttings in time during the drilling process. The purpose of chip removal is to maintain the quality and stability of the drilling hole, improve the production efficiency and the processing quality of the workpiece.
The chip removal of drilling machine is an important link that cannot be ignored in the drilling process. Whether manual chip removal or automatic chip removal is used, it is necessary to ensure timely cleaning of chip cutting to ensure the quality and stability of drilling.
