Skiving and roller burnishing is a specialized metalworking process used for deep hole machining. This technology is commonly used to achieve high-quality surface finishes and precise dimensional tolerances in long, narrow holes. Let’s take a closer look at what skiving and roller burnishing are and how they are used in manufacturing.
Skiving is the process of removing material from the interior surface of a workpiece using a cutting tool with multiple cutting edges. This results in a reduced pore size and a smooth, uniform surface finish. Roller burnishing polishing, on the other hand, involves the use of hardened rollers to compact and smooth the surface of the workpiece, thereby improving its finish and dimensional accuracy. When these two processes are combined, they form a powerful method for achieving superior hole quality.
Deep hole machining involves machining holes with a high aspect ratio, often using turning and tumbling. This is particularly beneficial for applications in industries such as aerospace, automotive and hydraulic systems, where precision and surface quality are critical.
The Skiving and roller burnishing process begins with a turning operation, where a cutting tool removes material from the interior surface of the workpiece. Next comes the roller polishing stage, where hardened rollers are forced through the holes, compacting and smoothing the surface to achieve the desired finish and dimensional accuracy.
The advantages of Skiving and roller burnishing include improved surface finish, reduced hole diameter deviation, and increased workpiece strength and fatigue resistance. Additionally, the process eliminates the need for additional finishing operations, saving time and costs during the manufacturing process.
In summary, Skiving and roller burnishing are essential techniques for obtaining high-quality, precision-engineered holes in deep hole machining. By understanding the principles and applications of these processes, manufacturers can optimize their production processes and provide high-quality components to meet the needs of modern industry.
