How exactly is a granulator knife sharpened?
- Professional knife sharpening is a process that involves various steps.
- Precise knife sharpening typically begins with cleaning and removing any residue, to facilitate a high-quality sharpening.
- The knives are then carefully measured and sorted to make sure that the least amount of knife material is removed. This ensures the tightest tolerances throughout the set of blades.
- To properly sharpen granulator knives, the knife is held in place and precisely rotated to match the exact angle requirements needed to meet the tolerances of the granulator machine.
- As the knife is sharpened, it is flooded with coolant to decrease heat and eliminate the risk of changing the hardness level of the material. Knife edges within a set are all ground simultaneously to a specific width to ensure optimized gap setting.
