There are many reasons to sharpen your industrial knives and blades with a professional such as Cutting Edge Knives. It’s common to drop off your knives at the local general machine store, but using a general machine store and not an expert who understands your industrial knives and blades could negatively impact your cutting operation. When you work with Cutting Edge Knives, you can rest assured knowing that your industrial knives and blades are in the hands of an expert who understands them. We have knowledge of metallurgy, abrasives, and cutting applications which allows us to choose the correct combination of wheels and segments for your material. Our skilled technicians can determine the exact combination of wheels and segments that will give you a superior cutting edge. 

In addition to having the necessary knowledge, at Cutting Edge Knives, we also have the correct grinding equipment. Not all grinding equipment and operations are created equally. When you bring your industrial knives and blades to a general machine store, chances are they will be grinding on the wrong type of equipment without the right type of coolant. This can lead to micro-fractures which can lead to large cracks and then to knives blowing up. You can avoid this huge safety hazard by taking your equipment to a knowledgable professional such as Cutting Edge Knives. We have the expertise and knowledge to help identify problems based on the wear patterns, cracks, and other damage. We inspect every knife before we sharpen it and we will let you know when it’s time to replace the knife when it can no longer be returned to working condition

When the life of your granulating blade is optimized, your production lines experience less downtime, your work environment is safer, and your output is consistent and reliable. To increase the life of your granulator blade, utilize a precision granulator knife sharpener, establish an appropriate feed rate, and accurately set the gap between your granulator blades. All of these steps will ensure the highest possible efficiency from your operation. 

Preventative maintenance can save your operation hours of unplanned downtime in addition to increasing the safety of the processing environment. In order to avoid unnecessary downtime, it is important to know how to recognize the early warning signs of a maintenance condition. 

To know if your granulator is working too hard, check the amp readings of your granulator just after maintenance, note the values, and then use this as a baseline. This baseline will help you determine when your granulator is working harder than it should. When amp readings increase this means the granulator blade is starting to dull and it’s time to change or sharpen the blades. A dull blade will also cause your granulator to lose efficiency and run hotter. As your granulator draws in more electricity, the internal temperate of the machine increases. This can lead to dangerous fire conditions and decreases the overall life of your granulator. 

To keep your granulator performing at its best make sure the gap between granulator knives is properly set and the gaps are consistent. The best gap size for your machine will be determined by the material being cut and machine specifications. If the particle sizes are uniform and you are still experiencing efficiency issues, your granulator knives may be wearing too quickly. An improper feed rate, imperfect blade material selection, and dirty and mixed material can all cause your granulator blades to wear prematurely.
