Drag and tangential cutting
Differences between drag and tangential cutting
Swivel or drag knife
Its simplicity has made drag knife (or swivel knife) technology, the most commonly used. In order to cut corners the knife can rotate freely in the knife holder. To orientate the knife direction, a drag-movement is made assuming the knife tip will follow accordingly.
Drag-movement
The drag knife cuts and stops before entering a corner
The eccentric blade is rotated by performing a drag-movement, while never leaving the media, to the desired angle
Once the drag-movement is finished the machine can continue cutting
Tangential knife
Tangential cutting technology guarantees a superior performance compared to commonly used drag/swivel knife techniques. The direction of the tangential knife is electronically controlled, by which T-series are capable of cutting very precise and with very high pressures. The perfect cutting makes weeding very easy, saving you a lot of valuable time.
Tangential movement
The tangential knife cuts and stops before entering a corner
The blade is lifted, for certain difficult corners, and rotated to the desired angle by an extra motor
Once the blade has the desired angle, the blade is lowered and cutting is continued
Conclusion
Drag knife
Faster cutting
Easier usage (only knife pressure adjust)
Tangential knife
More detail and smaller fonts
Thicker and rigid materials
More accurate knife depth adjustment
