Roller Burnishing

roller burnishing

Roller burnishing is a versatile metal finishing method that can be used on a variety of different applications. Roller burnishing tools come in many shapes and sizes. The two main varieties of these tools are single roll and multi-roll burnishing. This tooling is mainly used to achieve a specific surface finish, whether it is called out on a part print or for cosmetic purposes. There is no shortage of materials that roller burnishing tools work on, including steel, stainless steel, titanium, Inconel, aluminum, brass, bronze, cast iron, ductile iron and other ferrous and non-ferrous metals. The greatest advantage roller burnishing tools offer is their ability to eliminate certain secondary operations, in turn saving time and money.

Single roll burnishing tools are one of the most common tool types we offer at Monaghan Tooling Group. These versatileroller burnishing tools have been used in applications across the aerospace, automotive, heavy equipment, medical device, and many other industries. Single roll burnishing tools are offered for inside diameters (ID) and outside diameters (OD). There are a lot of different size options and roll options for single roll burnishing tools. Most rolls are made of carbide and can be refurbished to increase the life – and in turn – the value of the tool. Common applications for single roll burnishing tools include: bearing journals on shafts, ball joints, shafts for hydraulic and pneumatic valves, and shafts for electric motors.

Multi-roll burnishing tools are another popular tool-type we offer at Monaghan Tooling Group. These roller burnishing tools are offered for inside diameters (ID) and outside diameters (OD). These tools are used in a variety of different industries and help to improve part quality, along with eliminating secondary operations. Multi-roll burnishing tools come in three different styles: through-hole, blind hole and bottoming hole tools. The rolls from each style are replaceable wear parts that help to increase the life and value of the tool. Some applications for multi-roll burnishing tools include water pump bearing bores, oil pump bearing bores, seal & bearing bores in transmission cases, reclamation of cam & crank bores, bores in oil & gas valves and many, many other applications.

Roller burnishing tools are available in a standard size range or can be designed to fit your application. Monaghan Tooling Group and Elliott Tooling Technologies have also developed compact roller burnishing tools for applications where a machines’ working envelope is limited, as is found in most “swiss type” turning centers. For convenience, the body of the burnisher extends past the back of the tool block, allowing for quick and easy adjustment as required.

Roller burnishing tools are a fantastic way to improve your machining process and can be used on a variety of applications. If you would like to learn more about roller burnishing, contact one of our team members. We pride ourselves on being burnishing experts.
