Tangential Knives and Ultrasonic Knives
Tangential Knives and Ultrasonic Knives
Tangential knives and ultrasonic knives are specialized cutting tools used in cutting plotters, automated cutting systems and other precision cutting machines. They are designed for applications where accurate contours, clean cutting edges and precise material processing are required.
The knife design, cutting geometry and material are selected according to the machine, material and cutting process.
Tangential Knives
Tangential knives are cutting tools used in automated cutting systems and cutting plotters. Unlike rotary knives, the knife is guided along the cutting path and its orientation is controlled so that the cutting edge follows the required contour.
This makes tangential cutting particularly suitable for precise contour cutting and processing of sheet and flexible materials.
Typical applications include cutting:

• Plastics
• Rubber
• Felt
• Cardboard
• Leather
• Foams
• Films and other flexible materials

Tangential knives can be manufactured with different blade geometries and materials depending on the application. Carbide is particularly suitable for demanding applications where high wear resistance and long tool life are required.
Ultrasonic Knives
Ultrasonic knives use a high-frequency oscillating cutting movement to separate materials. The rapid vibration of the blade can reduce cutting resistance and support clean, precise cutting.
Ultrasonic cutting is used for a wide range of materials, particularly where conventional cutting methods may produce excessive deformation, fraying or material displacement.
Depending on the application, ultrasonic knives can be used for:
Plastics
Films
Textiles and nonwovens
Rubber and elastomers
Foams

• Composite materials
• Food products
• Technical materials

The appropriate blade geometry and material depend on the ultrasonic system, material properties and required cutting performance.
Precision Grinding of Tangential and Ultrasonic Knives
The cutting edge is critical to the performance of tangential and ultrasonic knives. Precision grinding ensures the required edge geometry, dimensions and surface quality.
Depending on the application, knives can be manufactured with specific cutting angles, edge geometries and materials to achieve the required cutting performance and service life.
Custom Tangential and Ultrasonic Knives
We manufacture custom tangential knives and ultrasonic knives according to customer drawings, specifications or samples.
Knife dimensions, mounting features, cutting angles and edge geometries can be adapted to the respective cutting system.
For demanding applications, carbide or other wear-resistant materials can be selected to increase tool life.
If you require tangential knives, ultrasonic knives or custom cutting blades, send us your drawing, sample or technical specifications. We manufacture precision cutting tools for automated and industrial cutting applications.
