With the development of economy, roller burnishing tool has become an indispensable rolling tool in our production and life. The appearance of this tool provides convenience for people’s production and life. But what problems do we need to pay attention to when using roller burnishing tools? Many people don’t know much about this, and we’ll give you a brief introduction. I hope our introduction will help you. First of all, the surface roughness after processing is also affected by the height of the raised part and the shape processing because the ID roller burnishing tool is the processing method using roller compaction. Therefore, the diameter of the workpiece will change after processing(the inner diameter will be enlarged and the outer diameter will decrease). This change should be considered in order to be able to be processed within the dimension tolerance. In the decision to formally batch when using, we need to consider the size of the process, the diameter of the variation and the workpiece is related material, hardness, rolling, so after 2 ~ 3 times to try processing initial determine its size.
Processing part of the wall thickness: roller burnishing processing is to use part of the surface of roller rolling processing, make its densification, so in order to can withstand pressure for machining parts, artifacts should have enough wall thickness. The wall thickness is too thick or too thin, after processing will have the fluctuation or the true roundness drop.
The hardness of the machining part: the hardness of the workpiece that can be processed by the rolling head is 40HRC, but it is also specially designed for the rolling head of the workpiece with high hardness (the upper limit is 55HRC). The machining part of the high hardness workpiece due to the high pressure, the roller burnishing tool’s life is shortened.
Rotate speed and feed amount: the rolling head is rolled to the right for rolling processing; fixed rolling head, workpiece rotation. Both methods can get the same result. The speed and feed speed vary according to the diameter of the machining.
For the application of rolling tools, the factors that need to be considered are introduced here. Through our introduction, we know the problems that need to be paid attention to when using rollers. I hope you can do a better job with the application of the rolling tool.
