How to solve the problems existing in Roller Burnishing Tools?

In rolling process, all kinds of Roller Burnishing Tools are necessary, whether Roller and Burnishing Tools or Flat Surface Roller Burnishing Tools. It is important to choose the right tools in the process. However, after a long period of use, we can find that there are some problems in the use of Roller Burnishing Tools, the wall thickness and hardness of the processing are required. Let’s get to know each other.


  1. The wall thickness of the processing part.

Roller Burnishing Tools is used to process the surface of the workpiece with rollers to make it densified. Therefore, in order to be able to withstand the processing pressure, the parts to be processed should have sufficient wall thickness (20% of the inner diameter). When the wall thickness is too thin or partially thin, the processing will have the fluctuation or the true roundness drop.

This is usually addressed as follows:

1). Reduction of roll pressure;

2). The use of clamps to support the outer circumference of the workpiece;

3). The rolling process is carried out before the thin wall thickness.


  1. Hardness of the processing part.

RBT Roller Burnishing Tools has a limit of 40HRC on the hardness of the workpiece, but also the roller head used for machining the high hardness workpiece (the hardness limit is 55HRC). When the rolling process is high hardness workpiece, the processing part is due to the high pressure, the tool life is shortened. Therefore, in order to obtain the required precision machining surface, the main measure is to reduce the rolling pressure.

In a nutshell, we know some of the requirements to be met in the use of extruders such as ID Roller Burnishing ToolsSingle Roller Burnishing Tools. The wall thickness and hardness of the part of the workpiece should be required. If not, we need to deal with it according to the above method. The wall thickness of the workpiece is too thin, the hardness is too high, these are not satisfied the condition. Choosing the right tool is the best.
