1. Appearance before rolling cutter processing
Because rolling processing is a processing method using roller rolling, the surface roughness after processing is affected by the height and shape of the raised part (that is, the condition before processing).
Assuming that the surface condition is rough before processing (high convex part and deep depression part), the convex part cannot be completely buried in the depression part, resulting in a rough surface for processing.
In addition, the shape of the raised portion also affects the appearance after processing. When the regular concave-convex shape is cut by a lathe or a boring sheet, and the height is easy to roll, the ideal appearance can be obtained. Generally, the better the appearance before processing, the better the appearance after processing, and the wear of the rolling head is also less. Assuming demand, a process can be added.
2. Dimensions before rolling
Because rolling processing is a processing method using roller rolling, the diameter of the workpiece before and after processing will change (the inner diameter will expand and the outer diameter will decrease). In order to be able to process to within the tolerance range of the scale, this change amount should be considered to determine the scale of the previous process. The amount of diameter change is related to the material, hardness, and rolling amount of the workpiece, so the scale is determined after the start of 2 to 3 trial machining.
3. Rolling drive machinery
The standard models of rolling head include Morse taper mounting part and parallel mounting part. Rolling processing is different from cutting processing. It does not require high torque and can also be used with low-power machine tools. It can be installed on drilling machines, lathes, hexagonal lathes, boring machines, drills and other equipment to stop processing without special equipment.
4. Smooth and clean
Because rolling processing uses roller rolling to stop processing, fine dust will be generated. Dust not only affects the appearance quality, but also accelerates the wear of the rolling head, so it is necessary to inject a large amount of cutting fluid to remove the dust. The cutting fluid with low viscosity should be used when rolling. The cutting fluid with high viscosity has good smoothness, but it has poor cleaning performance and is not suitable for rolling processing.
