A Comprehensive Analysis of Boring Pipe Processing Technology: From Principles to Application Scenarios
I. Principle and Definition of Boring Pipe Technology
Boring is a process for precision machining of the inner holes of workpieces by rotating cutting tools. Its core objective is to enlarge, trim, or improve the dimensional accuracy, shape accuracy, and surface quality of existing holes. Different from drilling, boring focuses more on the semi - finishing to finishing stages. Usually, single - edged or multi - edged boring tools are used and the process is completed on machines such as boring machines and machining centers. After boring, the holes can reach an accuracy of IT6 - IT7, and the surface roughness Ra value can be controlled between 0.8 and 3.2 microns. It is especially suitable for scenarios with high requirements for positional accuracy such as coaxiality and perpendicularity.
II. Core Application Areas of Boring Pipes
1. Hydraulic Systems: The cylinder barrels of hydraulic cylinders are typical application objects of boring pipe technology. Deep - hole boring can process high - precision seamless steel pipes, ensuring the sealing performance and stability of hydraulic equipment in high - pressure environments.
2. Mechanical Manufacturing: Complex parts such as engine blocks, gearbox housings, and bearing seats often require the boring process to achieve precise multi - hole cooperation.
3. Processing of Special Materials: Deep - hole processing of materials such as stainless steel and aluminum alloy has extremely high requirements for cutting tools and processes. With its high stability, boring technology becomes the preferred choice.
III. Key Methods of Boring Processing
1. Single - Edge Boring: It has high flexibility and is suitable for small - batch or special - shaped hole processing. By adjusting the cutter head, it can meet the needs of different hole diameters.
2. Multi - Edge Boring: Adjustable boring heads or floating boring tools are used. It has high efficiency and is suitable for mass production.
3. Deep - Hole Boring Technology: For deep holes with a length - to - diameter ratio greater than 5, a special cooling system is required to solve the chip - removal problem. It is commonly used in the processing of cylinder tubes and shaft - type parts.
