How Exactly Granulator Knife is Sharpened?
Proper knife sharpening is a process that involves various steps.
First, precise knife sharpening typically begins with cleaning and removing any residue, to facilitate a high-quality sharpening.
Then, the knives are carefully measured and sorted to make sure that the least amount of knife material is removed while ensuring 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.
To improve wear resistance and help prevent against other materials sticking to the knives, we suggest special coatings or even a cryogenic treatment after granulator knife sharpening.
Regular professional sharpening of a granulator knife significantly improves the performance of your granulator. On average, a granulator knife can be sharpened at least 10 times before reaching the end of their life. Every time, we take off only the damaged part of your granulator knife protecting the life expectancy of your blades.
At Fernite, we work within the strict tolerances to deliver a sharpened knife that is like new.
