General Burnishing Questions

Please refer to the chart:

The tool should be removed from the bore with a rapid feed.

The short answer is: yes. The stipulation is that material must be ductile in order for the burnishing process to work. The lower the ductility, the less results you get from the burnishing process. As materials get harder, they become less ductile. Therefore, the burnishing process has less effect on the material.

A multi-roller burnishing tool can be run on a lathe, mill, drill press or in some cases even by hand. A single point burnishing tool is meant to be run on a lathe but an exception would be in a boring head on a milling machine.

Yes roller burnishing works hardens the surface of the part. Please click here for the hardness table. Table Coming Soon!

Normally a coating will chip when burnished. Please consult us to discuss your specific application.

No. Plastic is not conducive to burnishing because it cannot be displaced, which is how burnishing works.

Our ID roller burnishing tools are interchangeable with the Madison-style ID roller burnishing tools. None of our other tools are interchangeable with any other brand.

Yes, coolant is necessary. Any good water-soluble or synthetic coolant will work with a recommended concentration of 8% or higher.

You can use oil in place of coolant if you prefer.

A single point tool is ideal so that the peak to valley ratio can be controlled. However, by adjusting the amount of stock left in the bore, you can burnish after reaming and possibly drilling.

ID Roller Burnishing Tool Questions

Yes. Most, if not all, of our tools are available with Imperial and metric shanks.

Our roller ID through and blind style burnishing tools are made with a right hand helix cage. They can only be run using a right hand spindle machine. If you would like a through style tool for a left hand spindle, it would be a special. Our full bottoming tools have no helix angle so they can run in either right or left hand rotating machines. Please call us to discuss.

This is all dependent on what kind of tool you require. Complete special tools of any kind typically take anywhere from 6-8 weeks. If the tool is a modified standard tool, the typical delivery is 3-4 weeks. Please call us with your specific application and we will quote accordingly.

Yes and no. Burnishing can help to improve the roundness of a part, but by design, is made to follow the existing bore. It may help to round it up, but we cannot guarantee that it will make it completely round.

Yes and no. It will depend on the diameter of the part and how much that diameter needs to be increased.

There is no clutch on a multi-roller burnishing tool.  The cage rotates via planetary gear rotation.  When the rollers make contact with the part surface they begin to rotate which then causes the cage to rotate at a slightly slower speed than the part in a turning machine or the spindle in a milling machine. (Link to roller burnishing animation.)

We manufacture three standard styles of rolls: Through, Blind and Full Bottoming. Our Through style roll has a short straight land behind the lead radius. This style of roll is only available on standard tools starting at .625 diameter. The Blind style has a lead radius and is also referred to as a close approach roll. It can burnish a through hole or burnish closer to the bottom of a bore than a true through style roll. The full bottoming roll is exactly what it sounds like, it is designed to burnish to the bottom of a bore. View it in the catalogue. Coming Soon!

Mechanical Joining Tool Questions

For most applications, the .031 radius roll will do an excellent job burnishing the part. However, there are applications and materials where other radii would be a better option. Please call us to discuss your specific application.
