Advantages of Roller Burnishing Tools

1. Cost Effective
   
   Roller burnishing is a cost effective method to achieve a good surface finish. Burnishing on a CNC lathe or mill can be less expensive than standard grinding.
   
   
2. High Surface Finish
   
   Roller burnishing can provide a surface finish between 0.05 Ra – 0.2 Ra on a turning or milling machine. This removes the need for secondary surface operations like grinding.
   
   
3. Surface Hardening
   
   The rolling method also has a work hardening effect for many material types, resulting in increased surface hardness. A harder surface will resist premature wear, improves corrosion resistance and increases the part service life.
   
   
4. Tolerance and consistently
   
   Size control is improved by burnishing. Use of a roller burnishing tool has the possibility of consistently attaining higher tolerance. In some situations an improvement in part roundness can also be obtained. This reduces the rework or rejections.
   
   
5. Simple to Use
   
   Burnishing tools can be used on non-CNC machines such as automatic lathes, semi automatic lathes and multispindle machines. The accuracy of the roller burnishing method is a function of the tool design, not the accuracy of the machine that is holding the tool.
   
   
6. Single Pass Operation
   
   Since roller burnishing is single pass operation very less cycle time is required to complete the job to required. A semi skilled operator can easily work.
