The Difference Between Ultrasonic Cutting Knife and Traditional Mechanical Cutting Tool
Conventional fiber material cutting methods include disk cutter cutting, broach cutting and reciprocating cutter cutting.
Their common shortcomings include:
1. Low cutting efficiency
Since conventional mechanical tools rely on pulling, rolling or reciprocating motion of the tool to break the workpiece material during processing, the cutting speed is limited.
2. Poor cutting accuracy
The lateral force is large during the cutting process of the tool, which is easy to cause deformation of the workpiece material, directly affecting the accuracy of the surface, and some micro-shaped surfaces are also difficult to process.
3. Sticky knife
The friction and thermal effects of conventional machining during the cutting process tend to result in sticking of the knife, resulting in a drop in cutting quality.
4. Tool and cutting head loss is large
Due to the large mechanical friction during the cutting process, the damage of the cutter and the cutting head is large, so the life is limited and the maintenance cost is also high.
5. Cutting limits
The weakness of traditional cutting methods is the inability to process certain high toughness materials. Typically, conventional cutting methods are not sufficient for the processing of Kevlar materials and the emerging dry UD materials.
Ultrasonic cutting can load ultrasonic vibration energy on the cutting tool. According to the basic principle of ultrasonic cutting, the energy can effectively break the boundary of the fiber material, so that the multi-layer fiber and prepreg can be realized in the above traditional cutting method. Cutting. Ultrasonic cutting fluids are more effective when cutting Kevlar and dry UD materials.
