The deep hole skiving roller burnishing machine is an efficient and precise deep hole machining equipment, and its working principle is mainly based on the composite machining technology of scraping and rolling. The following is a detailed explanation of its working principle:

　　1、 Basic composition

　　The deep hole skiving roller burnishing machine tool mainly consists of a host, deep hole fixture, scraper, rolling machine, driving device, cooling system, and working fluid circulation system. Among them, deep hole fixtures are used to fix workpieces, scrapers are used to scrape hole walls, and rollers are used to improve aperture accuracy and surface smoothness.

　　2、 Working principle

　　Scraping stage:

　　At this stage, the scraper enters the interior of the workpiece and scrapes the burrs and protrusions on the hole wall to reduce the thickness of the hole wall and preliminarily level it.

　　During the scraping process, a certain amount of friction and cutting force is generated between the scraper and the hole wall, thereby removing the uneven parts on the hole wall.

　　Rolling stage:

　　The roller then enters the interior of the workpiece to further smooth the already scraped hole walls.

　　Rollers are usually composed of multiple rollers that roll within the hole wall and apply a certain amount of pressure, thereby further improving the aperture accuracy and surface smoothness.

　　During the rolling process, rolling friction and compression are generated between the roller and the hole wall, resulting in a mirror like effect on the surface of the hole wall.

　　Coolant and working fluid circulation system:

　　Throughout the entire machining process, coolant is continuously injected into the workpiece through the working fluid circulation system to cool the machining area and remove the generated heat and chips.

　　The coolant also serves as a lubricant, reducing the frictional resistance between the scraper and roller and the hole wall, and improving machining efficiency and quality.

　　3、 Processing characteristics

　　High precision: capable of controlling aperture accuracy within 0.01mm, meeting the needs of high-end manufacturing industry.

　　High efficiency: By adopting automated processing methods, the efficiency of deep hole machining can be significantly improved.

　　Wide applicability: It can be used for processing workpieces of different materials and apertures, such as steel, cast iron, aluminum alloy, etc.

　　Good cooling effect: The cooling system can timely cool the machining parts, reduce thermal deformation of the workpiece, and improve machining accuracy.

　　4、 Application Fields

　　Widely used in aviation, automotive, hydraulic, textile and other industries for processing high-precision deep hole parts, such as aircraft engines, hydraulic systems, automotive engines, transmission systems, as well as hydraulic cylinders, hydraulic valves and other components.

　　In summary, deep hole skiving roller burnishing machine achieves high-precision and high-efficiency machining of deep holes through the composite processing technology of scraping and rolling. Its working principle is simple and clear, its processing characteristics are prominent, and it has a wide range of applications. It is one of the indispensable and important equipment in modern manufacturing industry.
