Customer concerns about ultrasonic cutting knives？
What is the difference between ultrasonic cutting knives and traditional cutting knives?
Ultrasonic cutting knife is a device that utilizes wave energy for cutting and processing. Its characteristic is edge free cutting. Or more precisely, there is no cutting-edge technology in the traditional sense. Traditional cutting uses sharp blades to press against the material being cut. The pressure is concentrated at the cutting edge, which is very high and exceeds the shear strength of the material being cut. The molecular bonds of the material are pulled, opened, and severed. Because the material is subjected to strong pressure and hard pulling, the cutting edge of the tool needs to be very sharp, and the material itself also bears relatively high pressure. The cutting effect is not good for soft and elastic materials, while it is difficult to cut sticky materials.
How long can my ultrasonic cutting knife last?
FUNSONIC adopts a unique electrical discharge wire cutting technology for production. And the subsequent stress relief technology reduces the material stress of the tool, thereby improving its service life. Before the fatigue characteristics of titanium became a problem, FUNSONIC's cutting blades could operate continuously for many years.
How can I maximize the lifespan of my cutting blade?
Accidental contact between the cutting blade and metal components (such as trays, belts, or other non food materials) can damage the cutting blade, while other non food materials can damage the blade. This type of misuse is the most common cause of damage to the ultrasonic tool head. Proper automation, proper machine programming, and good maintenance practices can greatly prolong the process. Operating the cutting tool with excessive amplitude can result in premature failure of the tool head due to the generation of additional fatigue stress. This is usually caused by the use of inappropriate amplitude shifters in the system. FUNSONIC will provide appropriate specifications for the amplitude lever when purchasing tools and recommend only using the specified amplitude lever. It is recommended to use only the specified amplitude lever for each tool.
Is it necessary to regrind my cutting blade?
Using ultrasonic technology, the sharpness of the blade is not as critical as mechanical knives. In fact, many designs of ultrasonic cutting tools have a small flat surface set on the tool tip to extend the tool's service life and improve performance. The vibration motion provides more cutting effects than the sharpness of the tool. If appropriate operating techniques are used and accidental tool collisions are avoided, there is generally no need to regrind during thousands of hours of operation. If the ultrasonic tool is worn or damaged, it should be sent back to FUNSONIC for re grinding. If the ultrasonic tool is worn or damaged, it should be sent back to FUNSONIC for re grinding and re adjustment.
