Adjust the perpendicularity of the laser beam with I2, and change the focal length so that the tip angle and clearance angle of the cutting edge are at a predetermined angle.
The laser beam is scanned several times and cut, and this cut surface is used as the flank surface z1. Support angle 24 made of diamond thin plate (Pito Chirib) B with cemented carbide after laser processing
Next, use a soldering pad made of A4-Cu-Ti alloy or the like to solder 1 piece 23 to form a cutting tool. When we conducted a cutting experiment on the T-luminium R7 base metal using a one-digit ultra-precision grinding machine, we found that the wax ftH2
No peeling occurred, and no damage to the cutting edge was observed. This is because the thickness of the diamond is considerably smaller than the thickness of the brazed portion 23), and when brazing during cutting, deformation of the portion has little effect on the diamond, and
The grain boundaries of Daihachi Send are also strongly bonded, making it difficult for the cutting edge to break.
