Granulator Cutter The so-called cutting gap is the gap between the moving and fixed knives. Today, let's talk about some key points to note when setting the cutting gap of the granulator cutter.

　　Within a certain range, a larger cutting gap requires less cutting force. Conversely, the cutting force is large, and the wear and tear on the cutting tool is also large. When the gap approaches zero, the cutting force will become quite large until the strength of the cutting edge cannot withstand it and a fracture occurs. However, if the gap is too large, the quality of the slices will be significantly affected, so the cutting gap must be reasonably selected in production. According to experience, the cutting gap of the granulator cutter is controlled between 0.03 and 0.04 mm, which can ensure a certain cutting force and obtain qualified slices.

　　The gap of the granulator cutter is closely related to the thickness and strength of the material being cut. In the shearing process, the sheet is not 100% sheared; in fact, it is partially sheared and partially broken.

　　1. The larger the gap of the granulator cutter or the greater the ductility of the material, the greater the burr. The smaller the gap, the smaller the burr, and the better the shearing dimensional accuracy.

　　2. In the cutting process of the cutter, the entire thickness of the sheet is not completely cut by the granulator cutter. Part of the sheet thickness is cut and then fractured, and the more brittle the material, the larger the fracture surface.
