Skiving and Roller Burnishing: An Overview.

In today's industrial world, various methods are employed to enhance the quality and functionality of different products. Skiving and roller burnishing are two of the most widely used techniques when it comes to finishing metallic surfaces. These processes help improve the surface finish, dimensional accuracy, and overall performance of a wide range of materials. Let's delve into the details and understand what skiving and roller burnishing are all about.

Understanding Skiving:

Skiving is a manufacturing process used to reduce the thickness of a material, most commonly metal. It involves removing thin layers from the surface with the aid of a cutting tool, typically a skiving knife. The process is performed in a controlled manner, minimizing any potential damage to the material being worked on. Skiving is commonly used to create sharp edges, reduce thickness, and improve the surface finish of materials.

1. Skiving Tools and Techniques:

Skiving requires specialized tools to ensure precise and efficient material removal. Skiving knives, typically made of high-speed steel or carbide, are used to cut thin layers from the surface. These knives are available in various shapes and sizes to suit different applications. With the advancement in technology, automated skiving machines have become common, enabling greater precision and faster processing.

2. Applications of Skiving:

Skiving finds its applications in a wide range of industries, including automotive, aerospace, medical, and manufacturing sectors. It is commonly used for thinning tubes, creating precise grooves, and improving the surface finish of components such as hydraulic cylinders, heat exchangers, and gun barrels. Skiving is particularly effective in industries where high-quality finishes are crucial to performance and durability.

Roller burnishing is a metal finishing process that improves the surface texture and hardness of a material. It involves pressing hardened rollers against the workpiece's surface, plastically deforming and smoothing it. The rollers used in this process have a controlled pattern of irregularities, which allows for effective smoothing of the material.

1. Roller Burnishing Tools and Techniques:

Roller burnishing tools consist of a housing containing multiple rollers or balls. These tools are attached to a machine, which applies a controlled force on the rollers to make contact with the workpiece's surface. The process is typically performed using a lathe, milling machine, or a dedicated burnishing tool. The rollers come in various designs, including spherical or conical shapes, and can be made from materials like hardened steel, carbide, or ceramic.

2. Applications of Roller Burnishing:

Roller burnishing is a versatile process used in various industries, such as automotive, aerospace, and oil and gas. It is commonly employed to improve the surface finish, hardness, and wear resistance of components like shafts, gears, cylinder bores, and molds. The process can generate mirror-like surface finishes, which enhance the performance and longevity of the finished products.

Closing Paragraph:

In conclusion, skiving and roller burnishing are two essential processes employed in the manufacturing industry to enhance the surface finish and functional properties of materials. Skiving is used for removing thin layers and creating precise surfaces, while roller burnishing is primarily focused on improving the surface texture and hardness of materials. These techniques find applications across various industries and contribute significantly to product quality and performance.
